Four passengers were kicked off of Saturday’s Delta flight DL4527 from Fort Wayne to Atlanta as a result of a flight attendant and passenger arguing over putting a cell phone into airplane mode.
Since the ban on use of electronic devices during taxi and takeoff was lifted, passengers are still supposed to have devices in airplane mode (non-transmitting) once the doors of the aircraft are closed. However this is almost never enforced at all, and certainly not systematically, on the hundreds of flights I take in the U.S.
