JetBlue ran its first official direct flight from New York City's John F. Kennedy Airport to Havana's José Martí International Airport on Friday, the first in a planned series of weekly charter flights. It's the first major airline to do so, though smaller outfit Sun Country was the first to start servicing the two cities, Time reports. JetBlue also runs flights to Cuba from Florida cities following the easing of travel restrictions earlier this year as the two nations work to restore diplomatic ties after half a century without relations.
