Cuba approves flights from 9 more American cities

United Airlines spokesman says one its jetliners carrying passengers from Washington to a Mexican beach resort has made an unplanned landing in Cuba due to a strange odor inside the craft.

The statement from spokesman Charles Hobart says United Airlines Flight 831 was carrying 135 passengers route to Cancun, Mexico, when the crew noticed an unfamiliar smell in the cabin.

Air travel between the United States and Cuba will become easier with the opening of charter flights to the forbidden island from an additional nine U.S. cities announced by Cuba authorities on Friday.

Cuban travel agency Havanatur Celimar said it added the cities of Tampa, Fort Lauderdale, Baltimore, Chicago, Atlanta, New Orleans, Dallas, Houston and San Juan, Puerto Rico, to the list from where charter flights would be accepted.

Cuba is preparing for an increase in visitors from its long-time ideological foe under a recent loosening of travel restrictions by the Obama administration.

The United States, which maintains comprehensive sanctions on the communist-run island and bans tourism to Cuba, does not allow regular commercial flights between the two countries.

But the Obama administration has lifted all restrictions on Cuban Americans visiting their homeland and allowed religious, academic and other professional travel by Americans to Cuba.

Havana Celimar has a monopoly on the Cuban end of U.S. charter flights and already receives travellers on flights from Miami, New York and Los Angeles.

The number of U.S. citizens visiting Cuba increased last year by 20 percent, to 63,000, according to Cuban statistics.

Some 350,000 Cuban Americans visited Cuba in 2010 after the Obama administration lifted all restrictions on their travel.

The travel opening annoyed Cuban American lawmakers who have introduced legislation in Congress that would reimpose a Bush-era restriction on Cuban American travel to the island of only one visit every three years and more strictly enforce the ban on U.S. travel to Cuba.

The lawmakers argue that the Obama administration is helping prop up the Cuban government, while the White House counters more people-to-people contact is the best way to undermine the island's communist system.

President Barack Obama has threatened to veto any move to undercut his people-to-people policy toward Cuba.
