Southwest Airlines is making moves in the Caribbean.
The carrier officially launched new daily nonstop service to four Caribbean destinations on Sunday, all out of its growing Caribbean-network hub in Fort Lauderdale.
The carrier has launched daily nonstop service from Fort Lauderdale to Grand Cayman, Cayman Islands; Montego Bay, Jamaica; Belize City, Belize; and Cancun, Mexico.
Also Sunday, Southwest launched two other new Caribbean routes: one between Cincinnati and Grand Cayman and the other between Chicago-Midway Airport and San Juan, Puerto Rico.
The new flights are the latest part of a major regional expansion for the low-cost carrier, which earlier this year launched service between Denver and Belize.
Southwest had already been operating daily flights between Fort Lauderdale and Nassau, Bahamas, along with a number of flights to destinations in Cuba.
The new flights represent the first significant challenge to competitor JetBlue’s fast-growing Caribbean network, as rival American Airlines seems to have slowed its expansion in the Caribbean.
