MIAMI – JetBlue Airways has announced more flights to Cuba and Haiti.

The New York-based airline said Thursday that it would add a new charter flight to Cuba this summer.

The Friday flights from Tampa to Havana will begin June 5. Travelers have to make arrangements directly with JetBlue partner ABC Charters.

Some restrictions on travel to Cuba were eased in January. JetBlue senior vice-president Scott Laurence says the addition reflects the “thoughtful approach we are taking in Cuba over the long-term.”

JetBlue already operates three other weekly charter flights to Cuba from Tampa and Fort Lauderdale.

The airline also announced new seasonal flights from Boston to Port-au-Prince, Haiti. Those flights will run from June 17 through Sept. 5. JetBlue also flies daily to Haiti from New York and Fort Lauderdale.
