Getting Enough Sleep

In October, the F.A.A. issued an operations bulletin for “ultra long-range flights” that doubled the amount of time pilots and flight attendants must remain at their overseas destination. The change to 48 hours from 24 is intended to make sure that flight crews get two full periods of sleep before making the return flight.

But seven airlines have asked the United States Court of Appeals for the Federal Circuit in Washington to set aside the new requirements, arguing that they would impose “substantial burdens and costs.”
