British Airways flies to more than 200 destinations around the world. This year the legacy U.K. carrier launched service between London Heathrow and Nashville and announced that it will fly from Heathrow to Pittsburgh beginning in April and seasonally from Heathrow to Charleston, S.C., also starting in April. In October, British Airways opened a First lounge in New York JFK's Terminal 7, part of a $65 million investment in the terminal that also included upgrades to check-in, security and boarding gates.
