Southwest Airlines is the latest commercial airline to cut back some of its routes to Cuba.
Starting Sept. 4, Southwest will no longer fly to two Cuban cities: Santa Clara and Varadero.
Varadero is one of Cuba's hottest destination and Santa Clara was the destination last year for the first commercial flight in decades to Cuba.
Airline officials said there is not enough sustainability in those markets, especially in light of the recent changes President Donald Trump made when it comes to travel policy toward Cuba.
But the discount airline is applying to add another daily round trip between Fort Lauderdale and Havana.
It currently has two daily flights to Havana.
Cuba reportedly earned $3 billion from tourism in 2016 and the Cuban government expects a higher income in 2017.
The number of foreign visitors is up 22 percent compared to the same period last year.
Cuba expects to reach a record 4.2 million visitors this year.
