Traveling by plane usually involves feeling cramped with little space between fellow passengers and luggage. But American Airlines plans to sell tickets that offer an upgrade from a seat to a whole suite.

American Airlines' new Flagship Suite business class is set to enter service in June. Here's where you can fly it first.

Set to debut on select flights from Philadelphia, American's Flagship Suite seats include privacy doors, personal storage space, a wireless charging pad and a chaise lounge seating option.
