American Airlines offers business class on long-haul international flights as well as transcontinental flying between major markets like New York and Los Angeles or San Francisco. American Airlines refers to its top-tier business class product as Flagship Business.

Flagship Business class has a lot of great perks to offer. Here’s what to expect when traveling in an American Airlines Flagship Business class cabin.

How to book American Airlines business class

In addition to purchasing an American Airlines business class ticket outright, travelers can also get a business class seat by redeeming AAdvantage miles.

The mileage cost depends on what route you're flying and the demand for that flight. If you're flexible, you can book American Airlines business class between the U.S. and Europe for as few as 75,000 AAdvantage miles each way.

AAdvantage members also have the option to redeem miles to upgrade after purchasing an eligible economy or premium economy ticket. Just note that mileage upgrades typically require a cash copay. Depending on where you're flying, a mileage upgrade may not be the best value.

Complimentary upgrades to Flagship Business are available to all AAdvantage elite members on transcontinental flights and flights to Hawaii. AAdvantage elites generally need to be booked on a paid ticket — not an award ticket — to be eligible for an upgrade. However, Executive Platinum elites can even score an upgrade on award tickets.

In addition, flyers can use systemwide upgrades to upgrade to American Airlines Flagship Business class for no additional cost. AAdvantage members can select systemwide upgrades through the American Airlines Loyalty Point Rewards program or earn them upon reaching Million Miler status.

The airport experience

American Airlines business class passengers can use priority check-in lines and accelerated security queues at some airports. Travelers can check two bags without charge, and these carry priority bag tags so that they should be delivered first upon landing.

During boarding, business class passengers can board through the priority lane. You'll get either Group 1 or Group 2 boarding, depending on if there's a first class cabin.

Flagship Business class passengers can access American Airlines Admirals Clubs and American Airlines Flagship Lounges on the day of travel.

The latter are impressive lounges with large buffets offering sushi, soups and salads. Self-serve bars offer a wide range of cocktails, wines, beers and champagne while refrigerators stock bottled water, juices and sodas.

Business class travelers flying into London Heathrow are treated to another special perk: the Arrivals Lounge.

Unique to London, it features a place to relax with a cup of coffee, refreshments, breakfast and showers. The lounge also offers clothes pressing so travelers can head straight to a meeting from the airport.

American Airlines business class seats

All American Airlines Flagship Business class seats can recline 90 degrees into fully-flat seats. Even better, on all American Airlines Boeing 777 and 787 aircraft, each seat offers direct aisle access — meaning travelers don't have to step over anyone to move around the cabin.

However, some American Airlines business class seats are better than others. Here's our breakdown of the best business class seats on American Airlines.

Best American Airlines business class seats

After a massive fleet simplification in 2020, American Airlines offers four types of business class seats. Here's our ranking of how they stack up.

1. Safran Cirrus II seats (Boeing 777-300ER)

The business class seat found on American Boeing 777-300ER aircraft is generally regarded as American Airlines' best business class seat. This reverse-herringbone business class seat is spacious, offers well-designed storage compartments, easily accessible outlets and seat controls. Most importantly, this seat avoids the pitfalls of other American Airlines business class seats.

These business class seats are found on all American Airlines Boeing 777-300ER aircraft. That means you can book this aircraft and know that you'll have an excellent business class seat. Unfortunately, that's not true for other American Airlines aircraft.

2. Collins Aerospace Super Diamond seats (Boeing 787-9, 777-200 and 787-8)

American Airlines' new business class standard is the Super Diamond seat. These seats are well-regarded for all facing forward, offering a variety of storage and feeling spacious.

The only ding against these seats is with the tray table. The tray table is stored under the in-flight entertainment screen, reducing the clearance of the footwell. Side sleepers may feel a bit squeezed in the thigh or knees when trying to sleep with the seat fully reclined.

Super Diamond business class seats are found on all American Airlines 787-9 aircraft, over half of 777-200 aircraft and the newest deliveries of 787-8 aircraft. On these newest aircraft, the seat has been improved even more with the addition of an adjustable privacy screen between middle seats.

3. Safran Concept D seats (Boeing 787-8 and 777-200)

American Airlines "Concept D" business class seats are typically considered American Airlines' worst long-haul business class seats. These seats alternate between forward- and rear-facing seat pairs.

The seats are connected to one another and aren't anchored down properly. So, when your seatmate moves, you'll feel it. These seats also don't have as much storage as the Super Diamond business class seats.
