An Alaska Airlines plane declared an emergency and made a priority landing at Seattle after taking off with a worker trapped in the cargo hold.
The pilot of flight 448, bound for Los Angeles, was alerted by the sound of banging “from beneath the aircraft”, an Alaska Airlines statement said.
The baggage handler emerged from the pressurised hold, saying he had fallen asleep inside it, the airline said.
The worker “appeared OK” but was taken to hospital as a precaution, it said.
The aircraft had been been in the air for 14 minutes.
Alaska Airlines said it was “actively investigating the matter”.
