Per an email reviewed by TheStreet, T-Mobile has advised customers that “free in-flight Wi-Fi may no longer be available on some flights and airlines starting April 13, 2026.”

The email does not specify which airlines are affected. T-Mobile says it “sponsors” free in-flight WiFi on Delta, Alaska/Hawaiian, and Southwest flights in partnership with Intelsat.

However, big changes in the airline industry (and satellite biz) are having impacts on the long-lived T-Mobile Wi-Fi that customers have come to rely on in flight. The good news is that even if T-Mobile’s “free in-flight Wi-Fi” offer goes away, its replacement will be more generous for everybody.

What does ‘T-Mobile sponsored Wi-Fi’ even mean?

It’s a common misconception that T-Mobile provides Wi-Fi on flights. Instead, T-Mobile simply pays an amount of money to “sponsor” Wi-Fi onboard, slapping its name on the side of the plane and taking credit for the satellite services.

For the most part, that means that T-Mobile has been the customer-facing name for Gogo In-Flight Wi-Fi through a partnership with its parent company, Intelsat. But as Gogo falls out of favor and the industry pivots towards new Wi-Fi, T-Mobile is sponsoring alternative solutions.

It just so happens to have a backup: SpaceX‘s Starlink, which it partnered with in 2022. However, not all airlines are continuing to accept T-Mobile’s money. The T-Mobile In-Flight Connection program no longer covers United and American Airlines.

Why United & American dropped T-Mobile Wi-Fi

At its core, many airlines are dropping Gogo Inflight because it’s slow, inconsistent, and outdated compared to ‘newer’ satellite options. This battle in the sky is getting increasingly congested.

In 2024, United Airlines announced that it would add Starlink to its aircraft, replacing Gogo on its fleet. The first flight with Starlink onboard was operated in Oct. 2025, offering free Wi-Fi to all United MileagePlus® members. Notably, T-Mobile is not involved in this pivot, much to the surprise of flyers who noticed the cell carrier dropped by the air carrier on Tuesday.

In January, American Airlines signed a similar partnership with AT&T, quietly discontinuing the free T-Mobile-sponsored Wi-Fi in favor of one sponsored by its competitor. Ironically, it will run on Viasat or Intelsat products — the branding is all that will change. Similarly, American’s new deal offers free Wi-Fi for AAdvantage members.

T-Mobile sponsors Starlink on Southwest, Alaska

Despite the changes at the aforementioned airlines, T-Mobile seems to still want its name out there. It’s putting on a new outfit to “sponsor” in-flight Wi-Fi on Southwest and Alaska.

While Southwest Airlines is in the process of replacing Gogo with Starlink on aircraft as part of an effort that it announced in February, Southwest continues to credit T-Mobile for offering “access to free WiFi fleetwide.” In other words, T-Mobile is paying to continue sponsoring Southwest Wi-Fi, even though it’s now using Starlink.

Alaska Airlines is striking a similar tone, just months after renewing its partnership with T-Mobile. It plans to add Starlink to its fleet in 2026, with plans to have it installed across its entire fleet by 2027.

JetBlue & Delta entertain a dark horse

It is worth saying: Not all airlines are going the Starlink direction. In fact, JetBlue and Delta are entertaining an alternative, which likely precludes a T-Mobile partnership.

For starters, JetBlue does not work with T-Mobile today. Today, JetBlue gets its high-speed “Fly-Fi” from ViaSat, but it plans to begin using Amazon Leo (formerly Amazon Project Kuiper) in 2027, becoming the first major carrier to add the still-unproven satellite constellation.

We say unproven because Leo is still not operating. Amazon plans to launch 1,500 satellites to orbit by mid-2026, but even then, it will pale in size compared to Starlink, which also sits in low Earth orbit.

To that end, Leo might end up being faster than Viasat’s GEO satellites by virtue of being closer to the plane, but with the constellation so close to Earth, scale will matter. That’s notable because by 2028, Delta plans to drop Gogo Inflight in favor of Leo, too.
