U.S. President Barack Obama plans to loosen Cuban travel policy to allow students to go to Cuba, the administration announced Friday. Also, more airports will be allowed to offer charter service. Right now, only three airports _ in Miami, Los Angeles and New York City _ can offer authorized charters to Cuba. That will be expanded to any international airport with proper customs and immigration facilities as long as licensed travel agencies ask to run charters from the airport. On Friday, one Florida airport was already taking steps to offer service to Cuba. The White House press office sent out a release saying Obama had directed the changes, which do not need congressional approval. They will be put in place within two weeks. Changes that Obama made last year already increased Cuban-Americans' ability to visit family and send money to relatives.
