Billionaire tech titans Elon Musk and Jeff Bezos are going head to head in the space race to make high-speed wi-fi a standard feature on commercial flights. 

In-flight connectivity is a key battleground amid airlines' push to attract premium customers, with Musk's Starlink and Jeff Bezos' Amazon Leo satellite network emerging as the main providers of the technology.

This year Starlink, which operates around two-thirds ​of all satellites in space and is the major driver of revenue for SpaceX, has already signed up 11 new airline customers for in-flight wi-fi provision.

Compare that to 22 new airline customers ‌in 2025 and eight in 2024, according to Valour Consultancy, an aviation intelligence firm.

Amazon, which is still building out its Leo satellite constellation, faces a huge setback after a spectacular Blue Origin rocket failure last month. It has signed up its first customers, securing deals with Delta Air Lines and JetBlue Airways.

Installing satellite broadband on airliners represents a major cost for airlines, running into the hundreds of millions of dollars for large fleets.   

But carriers increasingly ​rely on premium products like in-flight wi-fi to boost their margins, and they're likely to commit more heavily in the coming years - Decius Valmorbida, president of travel at Amadeus, a travel technology company, calls ​the technology as a 'game changer.'

'It's going to become a necessity that every airline will rush to have its own version of. It is becoming a ⁠must‑have,' said Valmorbida.

Starlink, which uses thousands of low-Earth-orbit satellites rather than larger, slower geostationary satellites, is much faster than legacy systems, according to Ookla, a broadband analytics firm.

In a sign of demand ​across the airline spectrum, Southwest Airlines said it chose Starlink for its 'speed to market,' but has not ruled out Amazon's Leo as it pushes for industry-leading wi-fi. 

'There's multiple ways to get there,' said Tony Roach, Southwest's ​chief customer and brand officer.

American Airlines said in late May it that would equip more than 500 narrowbody aircraft with Starlink starting in early 2027.

Not everyone is convinced: Ryanair CEO Michael O'Leary has ruled out adopting Starlink, citing costs and fuel burn from the antennas, prompting a fiery dispute with Musk.

Jefferies analysts estimate American Airlines' Starlink rollout could cost $150 million to $250 million for equipment and installation, based on its fleet, before annual service fees ​that could exceed $60 million.

Lluc Palerm, research director at Analysys Mason, said airline wifi 'will become a battleground' ​between Starlink and Amazon Leo, though Amazon remains limited as its satellite constellation is in its infancy.

SpaceX now holds Starlink contracts covering more than 7,000 aircraft, cementing an 'undeniable' lead, said Daniel Welch, a senior consultant at Valour Consultancy.

Palerm ‌said Starlink's ⁠early gains are meaningful because switching providers is costly: aircraft must be taken out of service for installations, onboard equipment is provider-specific and contracts typically run for years.

The airline sales come as SpaceX's upcoming record-breaking public listing has sharpened investor focus on Starlink's expansion beyond consumer broadband. 

Starlink generated $11.4billion of SpaceX's $18.67billion revenue in 2025, according to SpaceX's IPO filing, making it by far the company's largest revenue source.

Starlink is emphasizing speed and installation simplicity, while Amazon is pitching a broader technology ecosystem, including cloud computing, entertainment and retail links that it says can help airlines serve passengers beyond basic connectivity.

Delta's choice of Amazon Leo ​illustrates that distinction. The carrier selected Amazon Leo for ​an initial 500 aircraft beginning in 2028, ⁠building on its Amazon Web Services relationship.

Legacy in-flight wifi providers including Viasat, Intelsat, Panasonic Avionics and Hughes remain embedded across large fleets.
