  • With dozens of flights a day operated by several major airlines, the New York–London route is a fiercely competitive one.
  • American Airlines and British Airways operate a trans-Atlantic joint venture, and together offer the most flights a day between the two cities.
  • I recently flew a round-trip with one flight operated by American Airlines, and one by British Airways. Here’s how they compared.

American Airlines and British Airways have been relatively tight-knit partners since at least 1999, when the Oneworld airline alliance launched.

They became even more intertwined in 2010 when they formed a trans-Atlantic joint venture — along with fellow Oneworld member and Spanish flag carrier Iberia. Unlike alliance or code-share partners, joint venture partners collaborate to set routes and prices, and operate specific routes together as one business with immunity from anti-trust regulations.

Effects of the joint venture are seen more clearly on the high-demand New York City — London route than almost anywhere else. Flown dozens of times a day by at least seven different airlines, the route is a competitive one, attracting both cost-saving leisure travelers looking for the most cost-effective way to fly families across the Atlantic, and business travelers who book high-cost last-minute tickets for urgent meetings and conferences.

However, despite competition from other airlines flying the busy New York–London route, the American Airlines and British Airways joint venture dominates, partly because of the number of flights they operate on the route — about 15 on an average weekday, which is more than any competing airline offers.

The joint venture is tight-knit and seamless enough that when you search for flights on one of the airlines’ websites, results from both airlines appear, indistinguishable from each other aside from a tiny note staying that the flight is operated by the partner. That’s how my wife and I ended up with an outbound flight operated by American Airlines, and a return flight on British Airways metal. I bought the tickets through British Airways during a sale.

Not only did we fly a leg on each airline — we had a chance to fly the same exact type of plane, a Boeing 777-200. Although I usually fly between New York and the UK once a year or so, I hadn’t flown a long-haul American Airlines flight in economy in a while, and my last flight on British Airways, which was a few years ago, was on a different type of plane — a 747-400. So, I was curious to see how the experiences compared.

While both the American Airlines day-time flight to Heathrow, and the British Airways afternoon flight out of London Gatwick were pleasant, here’s how they compared in a direct head-to-head.
