JetBlue says it is investigating how one of its employees wound up in the cargo bin for a New York to Boston flight.

The man was discovered by baggage at Logan International Airport after the plane landed there on Saturday.

He reportedly told police that he became accidentally locked inside the aircraft's pressurized luggage compartment after falling asleep.

The 21-year-old man — whose name was not released — said he called JetBlue officials when he realized he was no longer on the ground.

A state police spokesman said the man was not charged with any crime and was returned to New York as soon as it was determined he was not dangerous.
