Delta Air Lines has all but finished its multi-year push to put free Wi-Fi on every flight. The airline says a new satellite that came online last week has closed its final coverage gap over the Pacific, meaning connectivity now stretches across even its longest routes to Asia, Australia and the South Pacific. More than 95% of its roughly 1,300 aircraft are equipped, with the full rollout expected to wrap up in the coming months.

Delta kicked off the trend back in early 2023 when it announced free Wi-Fi for members of its SkyMiles loyalty program, and most major US carriers have since followed suit. So a milestone like this should be a victory lap. Instead, the airline is facing awkward questions about its choice of technology.

The issue: Delta has opted not to install Starlink, widely seen as the fastest in-flight internet available today. Its biggest rivals are all in. United has Starlink on 43% of its jets and is running a pointed status-match offer to lure Delta loyalists. Alaska is around 40% complete, and Southwest says it expects to finish outfitting its whole fleet before either of them — all offering the service free to loyalty members.

Delta's response is twofold. First, it argues that full global coverage at scale — the same service on a regional jet or an Airbus A350 to Sydney, Melbourne or Auckland — is something competitors can't match yet. Second, it says the existing network is getting faster: aircraft are being switched to a new Viasat satellite with significantly more bandwidth, a process expected to be done on North and South America flights by Thanksgiving. Upgrades on regional jets and Boeing 717s are also finishing up.

Longer term, Delta is betting on Amazon's Leo satellite service, which it signed onto earlier this year as the world's largest airline customer. The catch is timing: Leo is unproven and won't appear on Delta planes until 2028. In the meantime, rivals will be flying with faster Wi-Fi today. Delta's chief marketing and product officer, Ranjan Goswami, compares the situation to repainting the Golden Gate Bridge — a continuous job built on what he calls a solid foundation.

For travellers, the practical takeaway is simple. If you're flying Delta soon, free Wi-Fi should be available on nearly any route, and speeds should improve noticeably through the end of the year, especially in the Americas. If blazing-fast internet is a priority and you're flexible on airline, United, Alaska and Southwest are currently mid-rollout on a system that's winning the speed argument — and all of them will give it away free if you join their loyalty programs. Either way, the days of paying for sluggish in-flight browsing are firmly behind us, and the competition is only making things better for passengers.
