All Three of Austin's European Nonstops Belong to Foreign Airlines

Austin-Bergstrom's transatlantic board is short and it is entirely foreign-flag. British Airways to London. Lufthansa to Frankfurt. KLM to Amsterdam. Three routes to Europe, and no US airline on any of them.

That may change next week. Delta is expected to announce nonstop Austin–Paris service on August 13, for a summer 2027 start. The report comes from the aviation account JonNYC; Delta declined to comment when Simple Flying asked. If it holds up, it would be the first transatlantic route a US carrier has flown from Austin.

American is not the airline making that announcement, and five years ago it would have been the obvious one.

American built Austin, then handed it back

In June 2021 American announced fourteen new Austin routes and talked up roughly a hundred peak-day departures once its partners were counted. At the top of the build it served more than three dozen destinations from the city, spending like a carrier building a focus city it never formally named.

Then it reversed. Twenty-one routes came out in November 2023. Nineteen more went in January and February 2024. Boston, Las Vegas, Nashville, Orlando and Raleigh followed that November, and Orange County ended in January 2025.

What survived is a set of connections. Over the twelve months through April 2026, American flew eleven destinations from Austin: eight of them its own hubs, plus Cancún and Los Cabos.

Delta flew twenty-six.

Southwest, then Delta, then American

Figures from The Frequent Flier's traffic database, built on the Transportation Department's T-100 filings, for the twelve months through April 2026:

• Southwest: 38,446 departures, 41.0% of the airport
• Delta: 19,396 departures, 20.7%
• American: 14,094 departures, 15.0%
• United: 11,497 departures, 12.3%

Delta carries 3.95 million passengers a year at Austin against American's 3.44 million, across more than twice as many destinations. Austin is one of Delta's three focus cities alongside Cincinnati and Raleigh-Durham, and Delta was still adding there last year: five new routes, fifty-five peak-day departures for summer 2025, roughly a fifth more seats.

American's remaining Austin flying is efficient. Its load factor is 80.2%, a shade above Delta's 79.8%. Eight well-filled hub flights is a rational operation to run. It is a smaller ambition than the one American announced in 2021.

Europe is the part nobody bid on

The three European routes are the fullest flights at the airport, running six to nine points above Austin's overall load factor, and between them they moved about 207,000 passengers in the twelve months through April.

Every one of those seats belongs to a European carrier.

There is history in the gap. Norwegian flew Austin to Gatwick from 2018 to 2020 and Austin to Paris on 787s before the pandemic ended both. Air France announced Austin–Paris for spring 2020 and never operated it. British Airways opened the market in March 2014 and carried more than a million Austin passengers in its first ten years, 191,181 of them in 2023 alone.

Both transatlantic joint ventures already reach Austin on European metal. British Airways flies London inside its joint business with American, approved by the Transportation Department in 2010; KLM flies Amsterdam inside Delta's joint venture with Air France-KLM. A Delta flight to Paris, Air France's hub, would be the first time either alliance put a US aircraft on an Austin route.

Austin has not gotten back to 2023

The airport's departures peaked at 97,937 in 2023. They have not recovered: 89,900 in 2024, 91,501 in 2025, 93,779 over the twelve months through April 2026. Traffic is being rebuilt around a different set of carriers than the ones that grew it.

Reliability tells on it too. Arrival on-time performance at Austin over the twelve months through May 2026 runs United 80.3%, Delta 78.3%, Southwest 77.0%, American 71.3%. American is the least punctual of the four majors at an airport where it now flies the third-most departures.

Delta is expected to say something on August 13. If a Paris route starts in summer 2027, the T-100 filings that would show whether Austin can hold a US-flag widebody won't land until the back half of that year, and our route pages refresh monthly as new filings arrive.
