A contract baggage handler who became trapped in the belly of an Alaska Airlines jet on takeoff from Seattle after falling asleep in the plane's cargo hold this week has been banned from all future work at the airline, a company spokeswoman said on Thursday.

The employee of Menzies Aviation, which is contracted to provide ground services for Alaska Airlines, made news on Monday as an unintended stowaway on Flight 448 when he woke up from a nap inside the sealed baggage hold to realize the plane was already airborne.

The pilot of the Los Angeles-bound flight turned the jet around to make a safe but unscheduled emergency landing back at Seattle-Tacoma International Airport after the crew and passengers heard banging from below the cabin and flight deck.
