jet drag

The feeling of exhaustion that is a result extensive and tiring plane travel. Includes, but is not limited to, security checkpoints, ticket collection, mad rushes to arrive at airport gates earlier than necessary, trying to keep up conversation with seatmates, adjusting the body for a wide variety of pressure and altitude changes, and lugging 40 pounds of luggage through international airports. May not necessarily pertain to time zone changes that are associated with jet lag.
