President Barack Obama has taken steps toward easing travel restrictions to Cuba. While scheduled airline flights to Cuba from the United States are not yet permitted, airlines can offer charter flights for Americans to travel to Cuba under certain circumstances, including "people-to-people" education exchanges with a sponsoring organization.
Airlines typically work with a charter operator such as Cuba Travel Services, which partners with American Airlines and JetBlue on charter flights to Cuba from other cities.
Delta CEO Richard Anderson earlier this year said Delta would resume flights to Cuba and launch scheduled service when allowed, but that it wouldn't be a "game-changer."
In addition to the charter flights Delta operated three years ago, Delta also served Cuba from 1953 to 1961.
