!MJN Air
* ComicTrio: Douglas the schemer, Martin the complainer, Arthur the idiot.
* FireForgedFriends: In the end, the crew of MJN have been through a lot together and will support each other, no matter what.
* JerkassHasAPoint: The MJN staff are doing their best, but nevertheless whenever another character suggests that they're cutting corners or are acting in an unprofessional manner, they've usually got a point.
* MeaningfulRename: At one point in the finale, as they scheme to [[spoiler:win the plane back from Gordon]], Carolyn refers to GERTI as Our Jet Still (rather than My Jet Now). Blink and you'll miss it, but [[spoiler:Douglas' pre-flight announcement at the end of the episode welcomes the passengers to "OJS Airlines."]]
* NotSoDifferent: In the series finale, Douglas implies that [[spoiler:he was like Martin when he was young and states that he got his confidence by impersonating his own captain, whom he admired, and eventually the confidence became real]]. The same, it seems, will happen to Martin as well.
* OddCouple: Martin and Douglas.
* OddlySmallOrganisation: MJN is an "airdot" as opposed to an "airline." Although there is a ground crew, the staff of MJN Air consists of the regular cast of two pilots, one steward and the CEO/stewardess. The problems created by only having the minimum two pilots [[DeconstructedTrope are occasionally acknowledged]], but justified by the company's PerpetualPoverty.
* PerpetualPoverty: The airline runs on a loss and every trip could be their last. Otherwise they'd be paying Martin...
* SexyStewardess: Averted.
--> '''Martin:''' For two very different reasons, neither Arthur nor Carolyn quite float my boat.
* VitriolicBestBuds: Martin and Douglas by the end of season three. Douglas will insult Martin endlessly, as he always does, but Martin is by no means above returning the favor for himself. And, despite the rampant jabs at one another, they do both certainly have each other's backs when the organic matter hits the spinning blades...

[[folder:Captain Martin Crieff]]
-->'''Played by''': Creator/BenedictCumberbatch
* AcePilot: Deconstructed. Martin is a very cautious and safety-conscious pilot, but not good at quick-thinking or improvisation in a tight spot. However, he landed the plane [[spoiler:on one engine after a bird strike]] in "St. Petersburg."
* {{Adorkable}}: Mostly insecure and sometimes nervously stumbling over his own words, but good-natured and a victim of bad luck. Just listen to him rattling off the Seven Dwarves in "Gdansk"! You just want to pick him up and hug him!
* AnimalsHateHim: In Uskerty, he winds up being attacked by bees and pestered by a goose, which then proceeds to [[spoiler: eat his father's signet ring]].
* TheBGrade: When Martin is told that he got 99% on a theory test (in which nobody has ''ever'' scored more than 84, and the testers conclude he must have cheated) he can only ask "... so I got a question ''wrong''?" [[spoiler:Turns out they were just confused by his British 7 (with no crossbar) looking like a European 1, so he was right after all.]]
* BuffySpeak: While he tries to be professional, Martin lacks Douglas's impressive vocabulary, and occasionally lapses into this.
-->'''Martin:''' But the thing is, weve taken away all the things that couldn't possibly have happened, so I suppose the only thing thats left, even though it seems really weird, must be the thing that did happen, in fact.
* ButtMonkey: His constant bad luck makes places him on the receiving end of many jokes, both in universe and out. Always being compared to Douglas doesn't help.
* CannotTalkToWomen: Gets tongue-tied when dealing with attractive women, e.g. Hester [=MacCauley=] ("Cremona"), Linda Fairburn ("Newcastle") and Princess Theresa ("Vaduz").
* CoolShades: Martin finds some aviators in "Johannesburg." He's reluctant to wear them lest Douglas mock him, but since Douglas isn't around he does -- and his confidence improves without the constant snarking as well. Of course by the end of the episode, before Douglas even gets a chance to get any good jabs in, they -- along with his newfound self-esteem -- get broken.
* {{Determinator}}:
** He qualified to be a pilot on his seventh attempt. Every time he failed he had to save up the money again in order to retry.
** He also managed to read and memorize the entire 600 page flight manual.
* EmotionalRegression: Suffers this when his brother and sister are around.
* ExpectingSomeoneTaller: It's a RunningGag that most people meeting Douglas and Martin assume Douglas is the captain.
* GeekPhysiques: Implied to be small and spindly. Has trouble getting people to recognise him as an authority figure. This can be a bit jarring when it comes to the promotional pictures, since Benedict Cumberbatch is actually six feet tall.
* GreenEyedMonster:
** Towards Douglas, who looks the part of an airline captain in addition to having the skills.
** In "Rotterdam", of the actor Carolyn hires to do the safety video also called Martin. Although eventually the two bond, when Captain Martin realises they are NotSoDifferent.
--> '''Martin''': See, you look more like a captain than me, you sound more like a captain than me, you've got a better uniform than me, and even a better name than me, [[SarcasmMode you must be very pleased]].
** And later:
--> '''Martin:''' How tall are you?
--> '''Other Martin:''' Oh, er... 6'2...
--> '''Martin:''' Ha! (to Douglas) Told you so Are you married? Oh, of course you are, kids too, I expect?
--> '''Other Martin:''' Yes, two.
--> '''Martin:''' Boy and a girl?
--> '''Other Martin:''' How did you know...?
--> '''Martin:''' Oh, just a hunch.
* GrewASpine: Martin noticeably manages to stand up to bullies in series 4.
* HardWorkHardlyWorks: Martin has devoted his entire life to being a pilot, sacrificing everything and working obsessively towards getting his licence and doing everything by the book which he has memorised. Yet all those years of dedication have made him merely competent, and markedly not as good a pilot as Douglas manages ''effortlessly'' to be - it just comes naturally to him, and absolutely doesn't to Martin. [[{{Determinator}} Not that Martin lets this stop him.]]
* InferioritySuperiorityComplex: He sometimes overplays his hand when demanding that people take him seriously.
* InsistentTerminology: It's ''Captain'' Martin Crieff! Most of Martin's interactions with Karl, the Air Traffic Controller, involve Martin berating him for neglecting to use the right terminology.
* LawfulStupid: When it comes to safety, to the point where he even [[ItMakessenseInContext refuses to allow an imaginary otter into the flight deck]].
* MaybeEverAfter: May or may not end up with Princess Theresa since the two have gone on some dates together and like each other.
* NoSocialSkills: Uptight, borderline neurotic, and utterly incapable of being "one of the blokes", even when he desperately tries.
* NotSoAboveItAll: Despite being a stickler for safety and professionalism, Martin is occasionally seen indulging his sense of humour during his cabin addresses on cargo flights, and goes out of his way to throw an improvised Christmas party for Arthur in the flight deck.
* OfficialCouple: [[spoiler:Martin and Theresa.]]
* PerpetualPoverty: He's not getting paid for being a pilot at MJN. Sometimes, for a treat, he has a baked potato.
* SensitiveGuyAndManlyMan: The Sensitive Guy to Douglas's Manly Man.
* SicklyNeuroticGeek: Has an "abnormality of the inner ear" that makes him reluctant to go swimming without earplugs in "Ipswitch", worries that being able to smell bacon might be a sign of impending doom in "Xinzhou", and plays up his injury to get out of hard work in "Ottery St. Mary".
* SmallNameBigEgo: Makes a big deal of the fact that he's an airline captain.
* TheUnfavourite: Always in the shadow of his elder brother Simon, and often bickers with his sister Caitlin, a traffic warden. However at the end of "Wokingham", his mother informs him that the whole family have always been proud of him, especially Simon.
* WellDoneSonGuy: Martin's late father tried to steer him away from becoming a pilot after he repeatedly failed his exams. Martin deeply regrets that his father never got to see him fulfill his dream.
* {{Workaholic}}: Aviation is his only interest.

[[folder:First Officer Douglas Richardson]]
-->'''Played by''': Creator/RogerAllam
* AcePilot: Deconstructed. Douglas is a highly (and effortlessly) skilled pilot, but a reckless one, his record of stunts resulting in his being knocked down to First Officer. For example, he managed to chase polar bears across Qikiqtarjuaq in a really old commercial charter plane, all the while making taka-taka noises.
* BecomingTheMask: Douglas reveals to Martin in "Zurich, pt. 2" [[spoiler:how he came by his calm and resourceful demeanor: he imitated Rory, [[AlwaysSomeoneBetter his first captain]] for "the first couple of years."]]
--> '''Douglas''': Then it just becomes part of who you are. That's why you have to pick your model carefully. You, of course, have picked ''terribly well.''
* BeneathTheMask: He appears supremely confident and self-satisfied, but this masks a deep and desperate desire to be a captain rather than a first officer (to the point where he [[spoiler:pretends to his wife that he's the captain]]). Douglas being Douglas, the mask is almost always extremely convincing. ''Almost'' always.
* BerserkButton: The fact that Martin caught him pretending to be the airline's captain to impress his wife.
* BrilliantButLazy: A natural pilot, but in "Ipswich" he outright says that he refuses to study and expects to pass the test on luck.
* BrokenAce: Downplayed because it's a comedy, but Douglas is a former alcoholic who has had a total of three unsuccessful marriages [[spoiler: and his most recent wife cheated on him with a Tai Chi instructor]].
* BornLucky: No matter the problem, he always gets out of it and looks brilliant doing so.
* BunnyEarsLawyer: Carolyn is fully aware of his love of {{Zany Scheme}}s, disregard for rules, and tendency to steal expensive whiskey, but he remains employed because of his skill as a pilot, as well as his general talent for getting MJN out of virtually any kind of trouble.
* {{Cloudcuckoolander}}: It's camouflaged by his impressive [[ExpospeakGag vocabulary]], [[InsufferableGenius intellect]], and [[DeadpanSnarker snark,]] but Douglas certainly has a bizarre sense of humour and a rather wacky imagination - his story about St Mary being eaten by otters is a good example, as are most of his cabin addresses and word games.
* CozyVoiceForCatastrophes: As evidenced by episode one, scene one.
--> '''Douglas:''' Just to let you know were making our final approach now into what I am ''fairly'' sure is Fitton Airfield. Unless its a farm. Or just possibly the A45. Its not the sea, because ''that''s blue...
* DeadpanSnarker: Douglas is the fount of eternal snark.
--> '''Carolyn:''' Now Douglas, as soon as we get to the motel, I want you to help me write my little speech for tomorrow.
--> '''Martin:''' What about me?
--> '''Carolyn:''' Well, okay, you too, but I want it to be unbearably snide and superior, so obviously Douglas is my primary resource.
* EstablishingCharacterMoment: His highly sarcastic cabin address in the cold opening to "Abu Dhabi", given in spite of the fact he knows that there are no passengers on the plane.
* [[GoodLookingPrivates Good Looking Pilots]]: Douglas has, apparently, put his pilot's uniform to ''very'' good use. He advises Martin to do the same, but Martin is [[NoSocialSkills too inept]].
* GreenEyedMonster: Towards Hercules.
* InsufferableGenius: To date, his skills include: aircraft piloting, cooking, piano playing.
--> '''Douglas:''' I'm very good at cooking.
--> '''Martin:''' Is there anything you're not 'very good' at? ''({{beat}})'' Douglas?
--> '''Douglas:''' I'm thinking. There are things I haven't tried yet. I suppose it's ''possible'' I'm not very good at some of those. Theoretically.
* JerkWithAHeartOfGold: He mercilessly teases his colleagues, but he becomes a good friend to Martin and a father-figure to Arthur.
* LargeAndInCharge: Subverted. Most people assume he's the captain because of his age and height.
* KarmaHoudini: He never gets a comeuppance for any of his schemes. Though being employed by MJN might be his punishment.
* MacGyvering: Many of his {{Zany Scheme}}s involve a form of this, most notably his solution in "St. Petersburg."
* ManipulativeBastard: Particularly towards Martin.
* NotSoAboveItAll: "Limerick" opens with Douglas bemoaning just how phenomenally boring flying from Russia to Limerick is, and inviting the passengers to the flight deck for sex. Fortunately, it's a cargo flight.
* OOCIsSeriousBusiness: When GERTI unexpectedly [[spoiler:"uses one of her engines to make a goose smoothie"]], both the fact that Douglas yells 'CHRIST!' in a genuinely shocked tone, and that he immediately becomes very professional and supportive of Martin alert us to just how perilous the situation is.
* OlderSidekick: A humorous variation. Douglas is first officer to Martin, who is younger and less experienced. Everyone always assumes Douglas must be the captain, which drives Martin crazy.
* SelfProclaimedLiar:
--> '''Douglas:''' I cannot tell a lie. What am I saying? I'm ''terrific'' at telling lies.
* SensitiveGuyAndManlyMan: The Manly to Martin's Sensitive.
* TallDarkAndSnarky: Depending on how canon [[WordOfDante the cast picture]] is. Roger Allam has dark hair, so most fans tend to assume that this applies to Douglas as well. Douglas's height, however, and his snark especially, fit this trope to a tee.
* [[spoiler: TheTeetotaler]]: Revealed at the end of "Fitton."
* TheAce: There's doesn't seem to be a skill he doesn't possess.
* TheCasanova: In his younger days.
* {{Troll}}: Teasing Martin, Carolyn and Arthur for any reason makes his job at MJN all the better.
* UltimateJobSecurity: An awful lot of his behaviour -- including low-flying GERTI over some polar bears having accidentally left the cabin address on so everyone on board can hear Martin screaming at him to stop, and stealing from the CEO at least once a year -- should at least get him suspended or disciplined. [[JustifiedTrope Justified]] by the fact that there isn't an alternative given MJN is an OddlySmallOrganisation, and he is very good at getting them out of tight spots at very short notice.
* WeaselCoWorker: Zigzagged. Douglas is certainly sneaky and a slacker, and often winds up getting Martin in more trouble than himself, but he is highly competent as a pilot, and is often the one who winds up bailing MJN out when trouble strikes.

[[folder:Carolyn Knapp-Shappey]]
-->'''Played by''': Stephanie Cole
* BerserkButton: Hates being called or treated as "a little old lady."
* DeadpanSnarker: Almost as much so as Douglas. The two often engage in SnarkToSnarkCombat.
* DesperatelyLookingForAPurposeInLife: Carolyn has put (lost) most of her share of her ex-husband's fortune into the airline, which has been running at a deficit for years. She holds on because being the CEO of MJN Air is "a good thing to be. Better than ... a little old lady."
* ExpectingSomeoneTaller: More than one person is surprised that the manager of MJN is a woman.
* TheILoveYouStigma: Herc and Carolyn in "Vaduz".
* MeanBoss: Certainly in the earlier seasons, although Series 4 has her [[PetTheDog being much nicer towards Martin.]]
* MisterMuffykins: Snoopadoop the cockapoo ("noblest of hounds!"), Carolyn's "ridiculous little dog". In Carolyn's defence, Arthur picked the name.
* NeverMessWithGranny: And while you're at it, you probably shouldn't call her "granny."
* NotSoAboveItAll: After witnessing Arthur's way of dealing with the ComicRolePlay intended to improve his stewarding skills (inventing new passengers played by himself who take over most of the requests, then turning on the seatbelt sign), Carolyn admits she might well have done the same thing and lets him borrow her car as agreed.
* OfficialCouple: [[spoiler:Herc and Carolyn.]]
* OohMeAccentsSlipping: Carolyn speaks with a more-or-less Received Pronunciation accent[[note]]Her vowels are generally a little more flattened than in 'classic' RP; this suggests the upmarket dormitory district of Cheshire, just south of Lancashire[[/note]]. Most of the time. In "Helsinki", when her Lancastrian sister turns up, Carolyn's accent gradually drifts back to her natural Lancastrian as she and Ruth spend more and more time bickering.
* PassiveAggressiveKombat: Carolyn and her sister Ruth.
* PlayingHardToGet: With Herc. He [[BelligerentSexualTension gives as good as he gets]], though.
* {{Tsundere}}: Behaves this way towards Herc.
* WomanScorned: The tone of the messages Carolyn leaves for her ex-husband definitely ring of this trope. And the airline is called "[[MeaningfulName My Jet Now]]."

[[folder:Arthur Shappey]]
-->'''Played by''': John Finnemore
* {{Adorkable}}: There's not a mean bone in this man child.
* BadLiar: In "Kuala Lumpur".
--> '''Douglas''': Answer this question with a lie. What's your name?
--> '''Arthur''': ''[stuttering]'' Arth...nold...man...er...cat...sir...man.
--> '''Douglas''': Arthnoldmanercatsirman... That's an unusual name. Tell me, is it made up?
--> '''Arthur''': Yes, it is. Augh!
** Douglas tries to teach him to lie better by using anecdotes from real life instead of trying to make things up, but this doesn't work since [[LimitedSocialCircle most of his anecdotes include the people he's trying to lie to]]. Telling Carolyn he's been at the dentist's when she took him last week, telling Martin he's been having lunch at an Italian restaurant with Douglas and Mar...[[LastSecondWordSwap k Ramprakash]].
* BerserkButton: Do NOT insult his mother.
** Admittedly his idea of going berserk is [[spoiler:putting a cake in someone's face]], but by Arthur's standards the merest hint of hostility is an extreme reaction.
** He's also furious when he's lied to, as shown in "Zurich" when he shouts at [[spoiler:his dad]] for trying to fool him into [[spoiler:returning GERTI to him]].
* TheDitz: Clearly neither book-smart nor street-smart.
* {{Cloudcuckoolander}}
* ConstantlyCurious: Arthur's attempts to find out from everyone else why aeroplanes can fly in "Abu Dhabi".
* DelusionsOfEloquence: Arthur has a habit of talking this way, combined with DepartmentOfRedundancyDepartment, when he goes into flight attendant mode;
-->'''Arthur:''' Ladies and gentlemen, as you can see our onboard transit process today has now reached its ultimate termination.\\
'''Carolyn:''' [[ExpospeakGag He means we've landed.]]\\
'''Arthur:''' Yes. So as yourselves prepare for [[PerfectlyCromulentWord disemboarding]], if I could kindly ask you to kindly ensure you retain all your personal items about your person throughout the duration of the disembarcation.\\
'''Carolyn:''' He means take your stuff with you.\\
'''Arthur:''' In concluding, it's been a privilege for ourselves to conduct yourselves through the in-flight experience today, and I do hope you'll refavor ourselves with the esteem of your forth-looking custom going forward.\\
'''Carolyn:''' ''[wearily]'' No idea.
* KavorkaMan: An InformedAttribute of Arthur's is his "mysterious and unaccountable pull over bossy pony-club types with Alice bands and stupid names".
* LethalChef: Arthur, inventor of such dishes as "surprising rice" and "fizzy yoghurt". The recipe for the latter is "yoghurt plus time."
-->'''Douglas:''' You're aware the reason for giving us two separate meals is to stop us both getting food poisoning? What's the point if you're just going to poison us both in two separate ways?
* ManChild: You wouldn't know he's in his late twenties.
* MommasBoy: He lives with Carolyn and loves and respects her above all.
* NoYou: Arthur responds to a fourteen-year-old saying his job is stupid with "no, ''you've'' got a stupid job!"
* OOCIsSeriousBusiness: Arthur's description of his dad.
-->'''Douglas:''' I think what we may be witnessing here, is Arthur trying to describe something with an adjective other than 'brilliant'.\\
'''Arthur:''' No, I wouldn't say he's b... well I mean, everyone's b... No, he's not ''brilliant.'' He's, ah... [[DamnedByFaintPraise he's all right.]]\\
'''Martin:''' God... he must be ''awful!''
* ThePollyanna:
-->'''Arthur:''' Brilliant! I love take-off delays.
-->'''Douglas:''' Oh, Arthur, please. Even ''you'' cannot love take-off delays.
-->'''Carolyn:''' ''(wearily)'' No, he does.
-->'''Arthur:''' Yeah! 'Cause take-off's the best bit of the whole flight, isn't it? And normally it's over before you can enjoy it. Whereas this way, we get to really build up to it!
* SarcasmBlind
-->'''Arthur:''' Mr. Birling said I'll never find another girlfriend.\\
'''Carolyn:''' I see. Well, Mr. Birling, the 70-something-year-old retiree from Sussex, is of course one of the country's leading experts on relationships, bu--\\
'''Arthur:''' Awww, is he? I didn't even ''know'' that!
** He's also terrible at ''imitating'' sarcasm, when he tries to imagine what kind of quip Douglas would make in their situation:
-->'''Arthur:''' I'm ''glad'' we're stuck under this bridge. That's a ''good'' thing.
* SelfInducedAllergicReaction: By eating dragonfruit in "Yverdon-Les-Bains."
* StaticCharacter: The only character of the main four not to undergo significant character development over the course of the show.
* TheWatson: He's usually the one to ask the pilots questions related to aviation and aeroplanes, which helps clarify the piece-that's-fallen-off-GERTI-of-the-week for the benefit of the audience. He becomes a much more ''literal'' Watson to [[CluelessDetective Martin's]] [[ActorAllusion "Sherlock"]] in the episode "Paris."

!Recurring Characters

[[folder:Gordon Shappey]]
-->'''Played by''': Timothy West
* BackForTheFinale: His last appearance before "Zurich" was "St. Petersburg."
* DamnedByFaintPraise: Martin and Douglas know Arthur's dad is going to be awful when Arthur describes him as "not brilliant."
* EvenBadMenLoveTheirMamas: Gordon claims in "Zurich" that the real reason he wants GERTI back is that it's named after his late mother. [[spoiler:Subverted in that Arthur immediately realizes he's lying, since of ''course'' he knows his own grandmother's name]].
* KickTheDog: Specifically, his treatment of Arthur.

[[folder:Mr. Birling]]
-->'''Played by''': Geoffrey Whitehead
* AwfulWeddedLife: With his "awful wife" Elizabeth
* OnceASeason: The annual tradition of "Birling Day," when they fly him to wherever the final of the Six Nations is being held.
* UnclePennybags: Mr. Birling's redeeming trait, at least in the minds of Douglas and Carolyn.
* ScrewTheRulesIHaveMoney: Because of his generous tips he knows he can do whatever he pleases on GERTI.

[[folder:Hercules "Herc" Shipwright]]
-->'''Played by''': Anthony Head
* AerithAndBob: The Shipwright siblings, whose father "was rather eccentric", are named Hercules, Wellington, Harrier...and Sarah ("he was eccentric, not mad").
* AcePilot: On par with Douglas in terms of flying experience.
* AlwaysSomeoneBetter: To Douglas.
* AwesomeMcCoolname: ''Hercules.''
* [[GranolaGirl Granola Guy]]: A strict vegetarian, apparently on moral grounds. Carolyn thinks it's because he's afraid that the sheep will come after him for revenge.
* TheILoveYouStigma: Herc and Carolyn in "Vaduz".
* OfficialCouple: [[spoiler:Herc and Carolyn.]]
* [[WhyDidItHavetoBeSnakes Why Did It Have To Be Sheep?]]: He's refuses to take a shortcut through a meadow because he's afraid of sheep.

[[folder:Princess Theresa of Liechtenstein]]
-->'''Played by''': Matilda Ziegler
* DeadpanSnarker: She's got a wicked sense of humour.
* EverythingsBetterWithPrincesses: Princess Theresa of Liechtenstein is a match for Carolyn - and as it turns out, in the other sense, for Martin!
* MistakenForPrankCall: Martin and Douglas each assume the other is behind a call from the Princess of Liechtenstein, with Martin asking if she needs [[DragonsPreferPrincesses rescuing from a dragon]]. Apparently it happens to her a lot. Later in the episode, Herc hears that the pilots have gotten a booking from the King of Liechtenstein and says "Well, that's clearly just Douglas doing a funny voice."
* ModestRoyalty: The Princess of Liechtenstein, who books her own flights and insists everyone call her Theresa. Her younger brother the King [[BrattyHalfPint is not an example]], and apparently neither is [[GrandeDame their mother]], of whom she pulls off a terrifying impression to cow Carolyn.
* OfficialCouple: [[spoiler:Martin and Theresa.]]
