United Airlines debuted Starlink Wi-Fi on its first passenger flight to Detroit, marking a milestone in in-flight connectivity with SpaceX’s satellite internet.

On Thursday, the morning flight from Chicago’s O’Hare International Airport introduced high-speed, gate-to-gate Starlink internet for United Airlines passengers. The Starlink-equipped United Embraer E-175, tail number UA5717, departed at 7:35 a.m. for Detroit Metropolitan Airport.

United announced the rollout on X, stating, “That lightning-fast Wi-Fi we told you about? It’s here. Our first customers just found out what it’s like to break the Wi-Fi barrier and stream, scroll, shop, and game just like at home with Starlink. And it’s FREE for MileagePlus members. Rolling out across our fleet now.”

The service leverages Starlink’s 7,000+ low Earth orbit (LEO) satellites to deliver broadband globally, including in remote areas. United is the only major U.S. airline currently offering Starlink. The airline plans to expand the service across its two-cabin regional fleet and introduce it on mainline flights by year-end.

Sean Cudahy from The Points Guy tested Starlink’s Wi-Fi pre-launch, praising its ease and reliability. “I ran a speed test, and it clocked the Wi-Fi at 217 Mbps of download speed, and 26.8 Mbps of upload speed,” Cudahy shared, noting its suitability for long flights.

Beyond aviation, SpaceX is pitching Starlink as a GPS alternative, emphasizing its potential for Positioning, Navigation, and Timing (PNT) services. This dual capability underscores Starlink’s versatility.

In a letter to the FCC, SpaceX wrote, “One opportunity stands out as a particularly ripe, low-hanging fruit: facilitating the rapid deployment of next-generation low-Earth orbit (‘LEO’) satellite constellations that can deliver PNT as a service alongside high-speed, low-latency broadband and ubiquitous mobile connectivity.”

As SpaceX expands Starlink’s applications, from aviation to navigation, United’s adoption signals a broader shift toward satellite-driven connectivity on long flights. With plans to equip more aircraft, United and Starlink are redefining in-flight internet, promising seamless digital access at 30,000 feet.

SpaceX is positioning its Starlink constellation as a viable GPS alternative. In a letter to the Federal Communications Commission (FCC), SpaceX stated that it could leverage Starlink satellites for next-generation Positioning, Navigation, and Timing (PNT) solutions.

GPS has been run through a single provider in the United States, the Defense Department. The FCC intends to use Positioning, Navigation, and Timing (PNT) solutions to complement GPS technologies. In its letter, SpaceX highlighted Starlink’s potential to deliver PNT services alongside its broadband offerings in its letter to the FCC.

“As the Commission identifies specific actions to contribute to the whole-of-government PNT system resilience effort, one opportunity stands out as a particularly ripe, low-hanging fruit: facilitating the rapid deployment of next-generation low-Earth orbit (‘LEO’) satellite constellations that can deliver PNT as a service alongside high-speed, low-latency broadband and ubiquitous mobile connectivity,” SpaceX wrote.

SpaceX also emphasized its ongoing work to integrate PNT into its cellular Starlink service, which is expected to be launched with T-Mobile in July. The private space provider also stated that Starlink satellites already operate independently of GPS. This lays the groundwork for resilient PNT delivery across authorized frequencies, SpaceX noted in its letter.

“SpaceX has also been actively working to integrate PNT solutions into its direct-to-device commercial service offerings. In so doing, SpaceX can advance the Commission’s goal in this proceeding to maintain American leadership in next-generation PNT services both here at home and in over 130 countries it serves around the world.

“SpaceX looks forward to playing an integral role in creating a more robust, resilient, and secure PNT ecosystem for Americans and people around the world,” SpaceX noted.

SpaceX also advocated for a “technology-neutral approach” to GPS alternatives in its letter, while critiquing EchoStar’s unused 2GHz spectrum for mobile satellite services. Meanwhile, Globalstar, Apple’s satellite provider, also pitched its services as a GPS complement, stating that its services “can function as either an alternative or a complement to GPS.”

“Notably, Globalstar’s satellites transmit outside of the L-band, which provides PNT users with added immunity from GPS jamming and spoofing. In addition, Globalstar’s satellite transmissions at 2.4GHz are stronger than GPS signals, bolstering resilience, performance, and reliability,” GlobalStar noted.

EU antitrust regulators are scrutinizing SES’s $3.1 billion bid to acquire Intelsat, probing whether SpaceX’s Starlink poses a credible rival in the satellite communications market. The European Commission’s review could shape the future of Europe’s space industry.

The Commission has sought feedback from customers of SES and Intelsat to assess Starlink’s competitive impact. According to Reuters, the questionnaire asks if low-earth orbit (LEO) satellite providers like Starlink and Eutelsat’s OneWeb are viable competitors for two-way satellite capacity. It also explores whether LEO suppliers are winning tenders and contracts and their potential to influence competition over the next five years. Additionally, regulators are evaluating customers’ bargaining power and ability to switch to rival suppliers.

SES operates a fleet of about 70 multi-orbit satellites for video broadcasting, government communications, and broadband internet. It aims to scale up through the acquisition of Intelsat. The move is part of a broader push in Europe to bolster home-grown satellite solutions, countering U.S. giants like SpaceX’s Starlink and Amazon’s Project Kuiper.

SES is in talks with the EU Commission and a few European governments to complement Starlink services, addressing concerns over reliance on foreign providers.

“Now the discussions are much more strategic in nature. They’re much more mid-term, long-term. And what we’re seeing is that all of the European governments are serious about increasing their defense spending. There are alternatives, not to completely replace Starlink, that’s not possible, but to augment and complement Starlink,” said SES CEO Adel Al-Saleh.

The EU Commission’s preliminary review of the SES-Intelsat deal is expected to conclude by June 10. The preliminary review will determine whether the SES-Intelsat deal is cleared outright, requires concessions, or faces a full-scale investigation if significant concerns arise. As Europe seeks to strengthen its space-based communication resilience, the outcome could redefine competitive dynamics in the satellite sector.

With Starlink’s LEO technology disrupting traditional satellite services, the Commission’s findings will signal how Europe balances innovation with strategic autonomy. SES’s efforts to scale and collaborate with governments underscore the region’s ambition to remain competitive, potentially reshaping the global satellite landscape as demand for reliable connectivity grows.
