The U.S. government on Thursday tentatively approved scheduled commercial airline service to Havana from 10 American cities, further bridging the gulf between countries as close as an hour flight but long kept at a greater distance by the Cold War, according to AP. The decision is another long stride in President Barack Obama's effort to normalize U.S.-Cuba relations. Eight U.S. airlines are expected to begin round-trip service as early as this fall between the U.S. and the Cuban capital, Transportation Secretary Anthony Foxx said. The U.S. cities are Atlanta; Charlotte, North Carolina; Houston; Los Angeles; Newark, New Jersey; New York; and four in Florida, Miami, Fort Lauderdale, Orlando and Tampa. Of the 20 daily nonstop flights allowed to Havana, 14 are from Florida, home to the largest population of Cuban-Americans.
