JetBlue Airways plans to install Amazon‘s Project Kuiper on some of its airplanes to bolster in-flight Wi-Fi, the companies announced Thursday, in a vote of confidence for the nascent internet satellite service.

The technology will be added to about a quarter of the airline’s fleet, with the rollout beginning in 2027 and expected to be complete in 2028, JetBlue President Marty St. George said on a call with reporters.

The team-up is a significant win for Amazon, which has been working to build a constellation of internet-beaming satellites in low-Earth orbit, called Project Kuiper. The service will compete directly with Elon Musk’s Starlink, which currently dominates the market and has 8,000 satellites in orbit.

Amazon has sent up 102 satellites through a series of rocket launches since April. It’s aiming to meet a deadline by the Federal Communications Commission, which requires it to have about 1,600, or half of its full constellation, in orbit by the end of July 2026.

The company hopes to begin commercial service later this year.

“Even though we still have a lot more work to do, we’re super excited to have JetBlue as the first airline customer for Kuiper,” Chris Weber, Kuiper’s vice president of sales and marketing, told reporters.

Starlink has signed up a growing number of airlines to use its services. JetBlue is Kuiper’s first airline partner, though Amazon has signed several deals recently as it tries to expand the service, including with European plane maker Airbus in April.

JetBlue has offered free in-flight internet for years through a partnership with Viasatwhich operates a network of geostationary, or GEO, satellites. That partnership will continue, St. George said.

He praised Amazon’s satellite service, saying Kuiper offers high speed, low latency and high reliability compared with GEO satellite networks. JetBlue could eventually use a combination of low-Earth orbit and GEO satellites for in-flight internet, St. George added.

U.S. airlines have been working to improve their in-flight Wi-Fi, which has long been derided for slow speeds and high prices.

Southwest Airlines on Thursday said it will offer free Wi-Fi to members of its Rapid Rewards loyalty program through a partnership with T-Mobile starting Oct. 24.

Delta Air Lines followed JetBlue in unveiling complimentary connectivity in 2023 for its SkyMiles loyalty program members. Hawaiian Airlines is using Starlink for free in-flight Wi-Fi, and Alaska Airlineswhich acquired that carrier last year, recently said it would outfit its planes with the same service.

United Airlines is also working to equip its planes to offer its loyalty program members free Wi-Fi through Starlink. American Airlinesfor its part, in April said it plans to have free in-flight internet on most of its planes next year for members of its AAdvantage program.
