A Thomson Airways flight to Bristol from Orlando in Florida had to turn back over the Atlantic after two crew members fell ill.
The plane was due to land in Bristol earlier today but had to return an hour after leaving America's east coast.
The airline said it was a medical emergency and that the safety of customers and crew was of primary importance.
Passengers were taken to local hotels and are due to arrive back at Bristol airport early tomorrow morning.
