On this flight, travel editor Madison Blancaflor was seated in first, cards and loyalty senior reporter Andrew Kunesh was in biz, reporter Chris Dong was in premium economy and senior reporter Zach Griff was in coach. TPG sent four reporters with a range of flight review experience on AA's flagship jet, the 304-seat Boeing 777-300ER, from JFK to Miami and back. With just two weeks left until these routes go all-Boeing 777, we decided to put it to the test - but not just in first or business class. In fact, two routes - Miami (MIA) to New York-JFK and MIA to Los Angeles (LAX) - will even exclusively be operated by Boeing 777 jets. In June, 2,855 domestic flights will be operated by AA's largest jets, per Cirium schedules. With domestic travel ramping up this summer, it's easier than ever to find a domestic flight operated by a wide-body, especially if you're flying American Airlines.
