President Barack Obama's historic trip to Cuba officially began Monday as President Raúl Castro greeted him with a military honor guard and the playing of the U.S. and Cuban national anthems at the Revolutionary Palace here.
On Tuesday, the Treasury Department was to invite U.S. airlines to submit applications to be allocated the new flights. American Airlines, Delta, United Airlines and JetBlue have previously expressed an interest in running regular flights to Cuba.
Mexico gave refuge to Cuba's Castro brothers in the 50s, then condemned Cuba's human rights record in the aughts. Now the countries' relations are again warming.
