Alaska Airlines had to cancel a flight out of California after a rat boarded one of its planes at Oakland International Airport.
The airline said that passengers were boarding the Portland, Oregon-bound flight on Tuesday morning when the rat jumped from the jet way on to the plane.
Passengers already on board came off, and the plane was taken out of service.
Most of the 110 passengers scheduled to take the flight were re-booked on a later flights to Portland.
'An Alaska Airlines aircraft departing Oakland International Airport was cancelled today due to reports of a mouse in the cockpit of the aircraft,' Alaska Airlines spokeswoman Keonnis Taylor said in an email to the Mercury News.
Taylor added: 'The flight's 110 passengers are being accommodated as appropriate by Alaska Airlines flights from San Francisco and San Jose airports.'
While most passengers were able to get new flights on Tuesday, some had to wait until Wednesday to fly out.
Alaska Airlines says it will resume using the plane when a professional exterminator certifies it is rodent-free.
The aircraft will also be inspected for any damage.
Oakland woman Ginger Hintz was one of the passengers who had to reschedule plans because of the rat.
'I asked the captain, "If we took a vote and accepted the risk of flying with it could we still go?"' Hintz told Mercury News. 'The pilot said he didn't want it around his feet. Maybe he had a phobia?'
She said she was given a $12 food voucher from the airline and was booked a new flight out of SFO - across the Bay from Oakland - on Tuesday night.
