FORT LAUDERDALE, Fla. (AP) - Spirit Airlines says it's canceling all of its Sunday flights after its pilots went on strike.
Pilots walked out Saturday morning in a pay dispute with the small, Florida-based discount airline.
The strike has already stranded thousands of travelers.
Spirit says it is refunding tickets and trying to get passengers onto flights on other carriers.
Spirit carries about 16,000 passengers a day, many of them between the Eastern U.S. and the Caribbean and Latin America.
