British Airways and American Airlines are two of the largest airlines in the world — and that dominance is pronounced on flights between the United States and Europe. But which airline should you consider for your next flight across the Atlantic? Let's look at British Airways versus American Airlines to see which airline you should choose.

Where they’re based and where they fly

Winner: American Airlines

For U.S.-based travelers, American is the clear choice when comparing route maps. While British Airways can be an excellent option if you're flying to London from one of the many cities that British Airways serves, American Airlines provides a broad reach throughout the U.S. and flies directly to plenty of international destinations.

British Airways

London-based British Airways currently flies to over 200 destinations across the globe. There's just one catch: when flying internationally, you'll usually need to connect in London to get where you want to go.

British Airways currently serves 26 airports across the U.S. — ranging from Atlanta to Washington D.C. But, you'll need to start at one of these airports to fly solely on British Airways. If you don't live in one of these cities, you can likely connect to a British Airways flight on American Airlines. But that will add yet another stop on the way to your destination.

American Airlines

American Airlines currently serves around 350 destinations in 50 countries. Although American is based in Dallas-Fort Worth, American hubs stretch across the U.S.:

Charlotte.

Chicago.

Dallas-Fort Worth.

Los Angeles.

Miami.

New York-JFK.

New York-LaGuardia.

Philadelphia.

Phoenix.

Washington-National.

American Airlines only flies directly to London from 11 U.S. airports, lagging behind British Airways. However, American serves a total of 14 European destinations nonstop. That means you can potentially eliminate the need to connect to get where you want to go. Even if you need to connect, domestic U.S. connections on American are easier than transiting through London.

Travel credit card availability

Winner: American Airlines

Not surprisingly, U.S.-based American Airlines wins this category. British Airways offers just one credit card option. Meanwhile, American Airlines offers a wide range of personal and small business cards — several of which make NerdWallet's list of the top airline credit cards on the market.

Airline loyalty programs

Winner: American Airlines

Although the British Airways Executive Club has some niche sweet spots, the American Airlines AAdvantage program is superior in several ways.

First, American continues to publish an award chart while British Airways hid its award chart years ago. The AAdvantage award chart prices flights by region, while British Airways award pricing is a sum of the Avios needed for each flight segment. Perhaps most importantly, American Airlines AAdvantage miles are much more valuable than British Airways Avios, according to NerdWallet analysis.

British Airways

British Airways Executive Club awards Avios — its mileage currency — based on the distance of the flight and the cabin in which you booked. Under this system, your earnings are the same no matter how much you paid for the flight. That’s a score for fans of cheap flights.

NerdWallet estimates British Airways Avios to be worth just 1 cent per Avios. That puts British Airways on the lower end of the spectrum compared to the other airline loyalty programs that we tested.

However, taking advantage of Executive Club sweet spots can potentially get a much higher value. British Airways' sweet spots include:

Flying to the Caribbean for as few as 7,500 Avios each way.

Booking nonstop domestic flights on American Airlines.

Flying to Hawaii for as few as 26,000 Avios round trip.

Upgrading with Avios.

British Airways Oneworld multi-carrier awards.

American Airlines

American Airlines utilizes a revenue-based loyalty program. Members earn 5 miles per dollar spent on tickets (before taxes and fees), with AAdvantage elite members earning a bonus on top of that. However, flying is far from the only way to earn AAdvantage miles. We've found a whopping 34 ways to earn AAdvantage miles.

American’s award chart is filled with plenty of value, both on American Airlines and its long list of Oneworld alliance and non-alliance partners.

NerdWallet's analysis found that American Airlines AAdvantage miles are worth 1.7 cents per mile for award redemptions. These figures put the value of American miles in the above average camp compared to of all airlines that we analyzed. It also represents a significant premium over the value of British Airways Avios.

Extra fees

Winner: American Airlines

British Airways add-on fees can quickly increase your travel costs. Even on standard economy fares, you'll need to pay to choose a seat up until 24 hours before departure. In addition, British Airways is the only airline in the Oneworld alliance that doesn't honor Oneworld elite checked baggage allowance on all tickets. And British Airways is only waiving change fees through September 2022.

Comparatively, American Airlines' policies seem downright generous.

British Airways

Checked bag fees: To find your checked bag allowance and fees, you need to use British Airways' baggage allowance calculator. Transatlantic fares generally include a free checked bag — except on basic economy fares where you'll need to pay up to $75. Even Oneworld top-tier elites don't get a complimentary checked bag on basic economy fares.

Seat assignment fees: British Airways frustratingly charges passengers for selecting a seat up until 24 hours before departure. The only exceptions are for passengers with elite status, who booked flexible fares or who booked first class.

Change fees: British Airways is waiving change fees for flights through Sept. 30, 2022, through its flexible booking policy. So you can change your dates or routes as many times as needed and only pay the fare difference.

American Airlines

Checked bag fees: American publishes a chart of checked bag fees by region. You'll pay $30 for the first checked bag on domestic flights. The first checked bag is free on standard economy fares for flights across the Atlantic, but you'll have to pay $75 if you’re flying basic economy.

Seat assignment fees: American Airlines passengers can select a standard seat for no charge, except when booking basic economy fares. If you want to sit together, basic economy passengers can choose a seat at booking for a fee. This fee is waived for elite members.

Change fees: When originating in North or South America, American Airlines flights are freely changeable for all domestic and short-haul international flights and particular long-haul international flights, as long as you don't book basic economy fares.

In-flight experience

Winner: British Airways

American swept every category so far. But, if you're solely focused on the in-flight experience, British Airways is the clear winner. From friendly and professional staff to free booze in economy, you may enjoy your flight more when flying on British Airways.

British Airways

On its long-haul international fleet, British Airways has taken strides over the past few years to install new economy, premium economy and business class seats — each with larger in-flight entertainment screens and better onboard amenities. Even in economy, British Airways serves excellent food and an extensive menu of non-alcoholic and alcoholic drinks. So yes, you can even get a gin and tonic in economy.

With that said, British Airways operates an entirely different model for intra-Europe flights. As British Airways competes with low-cost carriers on these routes, legroom is tight, and amenities are non-existent, while free drinks are limited to water.

American Airlines

American Airlines also invested in its "hard product" — installing new premium economy seats and excellent lie-flat seats in Flagship First and Flagship Business. However, that's where the investment stalled. As a result, American still struggles to provide consistently good onboard service and quality meals.

The bottom line

In the competition between British Airways versus American Airlines, there’s a clear winner: American Airlines. American Airlines provides a much more extensive route for U.S.-based flyers, additional credit card options, more valuable miles and lower fees. The only bright spot for British Airways is its superior in-flight experience — but only on long-haul flights.
