New Delhi, March 10 -- The Federal Aviation Administration briefly grounded all JetBlue flights early Tuesday morning due to a request from the airline, the agency said in a notice posted to its website.

It was not immediately clear why JetBlue requested the ground stop, which was lifted about 40 minutes after it was imposed.

The airline and the FAA didn't immediately respond to emails from The Associated Press requesting more information.

The airline, which was founded more than 25 years ago, has its headquarters in New York City and its flagship terminal at the city's John F. Kennedy International Airport.
