An Alaska Airlines flight that departed from Fort Lauderdale en route to Seattle had to make an emergency landing in Kansas City late Monday night because of the smell of gas.
KSHB-TV reported that more than 100 passengers were on the flight.
The plane was grounded around 11 p.m.
No one was hurt, but four flight attendants were sent to the hospital feeling lightheaded.
Two passengers said the airline offered them hotel rooms, but they said the conditions of the hotel were so bad they returned to the airport.
A replacement flight was not expected to arrive at the Kansas City airport until 12:30 p.m. Tuesday.
