British Airways is trying out biometric technology for international flights, making them the first UK airline to do so.

The technology enables fliers within the trial to "smartly" travel through the airport without having to show their passport, according to reporting from Travel Industry Wire.

American Airlines, a major U.S.-based airline headquartered in Fort Worth, Texas, is planning on eliminating first-class tickets on international flights.

In an investor call, Vasu Raja, chief commercial officer for American Airlines, said, "First class will not exist on the 777, or for that matter at American Airlines, for the simple reason that our customers aren't buying it."
