Amazon Leo (Kuiper)
Amazon's LEO satellite constellation, rebranded from Project Kuiper to Amazon Leo in November 2025. It now has both JetBlue (rollout from 2027) and Delta (500 aircraft from 2028) signed, but no commercial aircraft are flying with it yet.
Amazon Leo is the new name for Project Kuiper, Amazon's LEO satellite constellation built to compete with Starlink. The rebrand landed in November 2025; the aviation deals followed fast. JetBlue signed first, in 2025, to replace Fly-Fi's Viasat service starting 2027. Delta followed on March 31, 2026 with the bigger one: 500 aircraft, installs starting 2028. That answered the question of what the last two Starlink holdouts among big US carriers would do. Amazon has committed to 3,236 satellites and is still deploying, so no commercial aircraft are flying with Leo yet. First passenger flights are realistically 2027 on JetBlue.
Strengths
- Expected speeds and latency comparable to Starlink
- JetBlue and Delta deals make it the credible second LEO option
- Competition should pressure aircraft-WiFi pricing downward
Drawbacks
- Not operational on any commercial aircraft
- Constellation still ramping, far fewer satellites in orbit than Starlink
- No real-world flight performance data yet
How fast is Amazon Leo (Kuiper) in flight?
Not measurable yet. Amazon's marketing materials suggest 100-400 Mbps with latency under 100ms, comparable to Starlink. Real-world performance depends on constellation density (still ramping), antenna design, and the aircraft hardware Amazon eventually ships. Until first deployments, treat the specs as projected.
Is Amazon Leo (Kuiper) free?
Pricing not announced. JetBlue's current Fly-Fi is free to everyone and the Leo transition is expected to keep that. Delta's free-WiFi-for-SkyMiles-members model will presumably carry over to Leo aircraft. Nothing is confirmed until planes fly.
Amazon Leo (Kuiper) FAQ
When will Amazon Leo WiFi be available on flights?
JetBlue is the launch partner, with installs expected to start in 2027 as Fly-Fi transitions off Viasat. Delta follows in 2028 with a 500-aircraft program. No firm in-service date has been published for either.
What happened to Project Kuiper?
Amazon renamed it. Project Kuiper became Amazon Leo in November 2025, a nod to low Earth orbit. Same constellation, same aviation ambitions, new brand.
Which airlines have signed with Amazon Leo?
JetBlue (2025, fleet-wide Fly-Fi replacement starting 2027) and Delta (March 2026, 500 aircraft starting 2028). Those are the two biggest US carriers not on Starlink, which makes Leo the de facto second camp in the LEO WiFi race.
Will Amazon Leo be faster than Starlink?
On paper the specs are comparable. Both target similar speeds (100-400 Mbps) and similar latency (sub-100ms). Real performance won't be known until aircraft start flying with it. Starlink has a multi-year head start on orbital density.
Is Amazon Leo free on planes?
Pricing not announced. JetBlue is expected to keep the free-WiFi passenger experience it has had since 2017. Delta gives free WiFi to SkyMiles members today and has said nothing about changing that on Leo aircraft.
Should I wait for Amazon Leo before booking flights?
No. Leo isn't on any aircraft yet. If you want the fastest in-flight WiFi available today, look for Starlink-equipped flights. Leo becomes relevant in 2027 and beyond, as JetBlue and then Delta start installations.
Why is Amazon competing with Starlink?
LEO satellite broadband is a multi-billion-dollar market across aviation, maritime, government, and consumer. Amazon has the engineering depth and launch capacity to build a credible alternative. Airlines want a second-source supplier so they're not locked into SpaceX terms. The JetBlue and Delta deals prove that demand is real.
