WASHINGTON, Nov. 28 (Xinhua) -- The first scheduled commercial flight from the United States to the Cuban capital Havana in more than half a century landed on Monday amid uncertainty about U.S. President-elect Donald Trump's Cuba policy.
The American Airlines launched the flight from Miami, Florida, and it has more business plans to fly to Havana including a flight from Charlotte, North Carolina on Wednesday.
Earlier this year, several U.S. airlines started flying routes to other cities of Cuba, which is some 145 km away from Key West, Florida.
Before the airliner landed in Havana, Trump tweeted that he might "terminate" the thaw in U.S.-Cuba relations initiated by President Barack Obama.
"If Cuba is unwilling to make a better deal for the Cuban people, the Cuban/American people and the U.S. as a whole, I will terminate deal," he said.
The tough comment requesting more concessions from Cuba is suggestive of a hard-line stance and is expected to raise more speculation and uncertainties about Trump's Cuba policy after the death of Cuban revolutionary leader Fidel Castro on Friday.
Washington resumed diplomatic relations with Cuba in July 2015, with its 55-year-long trade embargo against the Caribbean island nation still in place.
In 1961, Fidel Castro declared Cuba a socialist country. Before that, large-scale reforms he led, including nationalization of industries and banks, prompted Washington to sever ties.
Negotiations to normalize U.S.-Cuba ties began since two years ago between Obama and Fidel Castro's brother Raul Castro, who succeeded him in 2006.
U.S. media reported Trump's aides said nothing on Cuba has been decided.
However, a change to reverse the existing course is expected to face pressure from advocates of the detente and the business people.
The U.S. daily commercial flights bound for Cuban cities and more expected for Havana represent a U.S. corporate investment in the island as well as economic interests on both sides.
The flights to Cuba are "the key thing to watch," said Darrell West, senior fellow at the famous Washington-based think tank Brookings Institution. "That is where the greatest opening took place and it is the ones where companies already have invested the most."
"Trump has appointed hardliners to his administration so he may well reverse Obama's policies," West said, while noting the possibility of a moderate approach by Trump.
"His background as a developer of hotels, casinos, and resorts may guide his instincts on this issue in favor of further investment in Cuba," he said.
