American Airlines formally opened an office in Havana Wednesday, and an executive said the company will move ahead with its plans for Cuba despite uncertainty over what president Donald Trump's administration will bring. The inauguration came 2 months after American Airlines flew the first scheduled commercial flight from the US to Havana in more than 50 years. Several airlines had begun routes to other Cuban cities earlier and before that there were costly charter flights. The company said the flight and the office reflected the company's commitment to doing business on the island after president Barack Obama initiated detente with Cuba. Obama's successor has criticised that move, and before his inauguration tweeted that he might "terminate" detente between the US and Cuba. <br/>
