Jet lag: physical condition caused by crossing time zones during flight. The condition is generally believed to be the result of disruption to the circadian rhythms (i.e. the "light/dark" cycle) of the body. It can also be exacerbated by experiencing sudden changes in climate or seasonal conditions, as well as the reduced oxygen, partial pressure, excess noise and low humidity commonly experienced in the cabin of an aircraft.

Air Frace: incompetência; meter os pés pelas mãos; aldrabões; etc.
