Death in the Clouds
A standard mystery plot: someone is murdered on a passenger flight while it is in the air. From a writer's perspective, this has the advantage of providing both a closed setting and a limited suspect pool without either feeling overly contrived. These days it also provides the additional puzzle of how the killer smuggled a weapon on board. The detective can either be on the flight or brought in once the plane has landed. The successor to Thriller on the Express (though it still gets used in non-modern settings).
As a Death Trope, all Spoilers will be unmarked ahead. Beware.
