Amazon's satellite service, Amazon Leo, will be available on Delta Airlines flights starting in 2028, the company has announced.

Under a multi-year agreement, Delta will begin rolling out Amazon Leo with an initial installation on 500 aircraft in 2028.

Amazon Leo, formerly Project Kuiper, is a low-Earth orbit connectivity-focused satellite constellation, similar to SpaceX’s Starlink. Amazon currently has more than 200 satellites in orbit, while Starlink has more than 10,000.

Amazon said its deal with Delta will provide customers with low-latency Wi-Fi “from gate-to-gate” and will be free for all Delta SkyMiles members. Amazon said the deal builds on a previous relationship with Delta, which began with Delta migrating its technology infrastructure to Amazon Web Services.

“Delta’s future is global,” said Ed Bastian, Delta CEO. “This agreement gives us the best, fastest, and most cost-effective technology available to better connect the world today, and it deepens our work with a global leader that shares our ambition to build what’s next—creating even stronger human connection for our people and our customers for years to come.”

Andy Jassy, president and CEO of Amazon, added: “We’ve designed Leo to provide high-speed internet to the billions of people on Earth without reliable connectivity, and this agreement with Delta is a great example of the impact and scale of the technology – bringing even faster in-flight Wi-Fi to tens of millions of passengers who fly Delta every year.”

“People increasingly want to stay connected wherever they are in the world, and Leo’s speed and reliability are going to have a big impact for businesses, governments, and consumers. It’s going to make the in-flight experience so much better, and it’s going to change what’s possible while traveling.”

This is the second airline to tap Amazon for satellite services, following JetBlue last year.

To date, Amazon has signed deals for Leo with Vodafone and Vodacom, Verizon, NBN Co., and Vrio. An AWS deal with mining company Gold Fields mentioned using what was then Kuiper for connectivity at its remote locations.

This announcement comes just a day after Irish flag carrier airline Aer Lingus announced that SpaceX's Starlink service had been onboarded to the first aircraft in its fleet.

In response to the announcement, Elon Musk, founder and CEO of SpaceX, which owns Starlink, crudely referred to the launch of Starlink on Aer Lingus as a “cunning” move, an apparent reference to the sexual act of cunnilingus.

Several major airlines offer Starlink on board, including British Airways, United Airlines, Qatar Airways, Air France, and Air New Zealand.
