For years, airplane wifi was an expensive joke: pages that never loaded and video calls that dropped. Between satellite constellations, newer antennas and post-pandemic demand, a lot has quietly changed. Here is what is actually true now, what it costs, and how to tell before you book whether your flight will have usable internet.
The honest summary is that airplane wifi has gone from mostly useless to genuinely usable on a growing share of flights, but the gap between the best and worst equipped aircraft is now enormous. On a Starlink-equipped plane you can stream video and take calls. On an aging ATG-equipped regional jet you will struggle to load email. The route to a good experience is knowing which aircraft you are on before you fly.
The three generations of airborne internet
Air-to-ground, or ATG, was the first generation and still flies on thousands of aircraft, especially on domestic narrow-bodies in North America. Two antenna towers on the bottom of the plane talk to cell towers on the ground. Because the system never leaves the ground network, latency is decent, often 100 to 150 milliseconds, but bandwidth is thin, the connection only works over land, and it saturates when the cabin is full. If you have ever paid twenty dollars and then watched a spinner for three hours, this is probably why.
The second generation is older satellite service over Ku-band, using conventionally pointed antennas that track satellites as the plane moves. Coverage is near-global, including over oceans, but bandwidth per aircraft is modest, latency sits around 600 to 800 milliseconds because the satellites are in geostationary orbit 35,786 kilometres up, and weather can degrade the link. This is still the workhorse on most long-haul fleets worldwide.
The third generation is where the real change happened. Low Earth orbit constellations, chiefly Starlink with around 7,000 operational satellites at roughly 550 kilometres altitude, cut round-trip latency to 30 to 60 milliseconds, which is better than many home connections. Flat electronically-steered antennas with no moving parts track the constellation continuously. Airlines including Qatar Airways, United on many routes, Hawaiian, and a growing list of others have installed Starlink kits, and where it is installed the experience is closer to airport lounge wifi than to the airplane internet of 2019. Meanwhile next-generation Ka and LEO-hybrid systems from Viasat, Inmarsat and Panasonic are lifting Ku-class aircraft toward hundreds of megabits per plane.
The Ka-band systems flying on newer aircraft are the middle story. Viasat-equipped jets, common on some European and Middle Eastern carriers, routinely deliver 20 to 40 Mbps to the aircraft, enough that a full cabin can browse and stream without collapse. If your aircraft is listed as Viasat or Ka-band equipped, expectations can be reasonable.
What it costs in 2026
Pricing has consolidated around a few patterns. Many North American carriers bundle wifi into subscriptions: monthly plans in the 30 to 50 dollar range for unlimited domestic use, which pays for itself in two or three flights if you fly regularly. European low-cost carriers often sell session passes from 3 to 10 euros for messaging tiers up to 25 to 35 euros for full streaming tiers on longer sectors. Full-service long-haul carriers increasingly give a free messaging tier to all passengers and charge 15 to 30 dollars for the full-flight premium tier. A few carriers, notably those racing for goodwill with Starlink installs, now offer the whole thing free to every passenger, speed limits included, and treat the cost as marketing.
Tethering logic also matters. If you have a phone plan with airline wifi benefits, several major carriers and premium credit cards include free or discounted passes on specific airlines. Check that before paying the walk-up price at 38,000 feet, which is always the most expensive way to buy.
How to know what you are getting before you fly
This is the part most people get wrong, because the airline brand tells you almost nothing. Equipment varies aircraft by aircraft. Three practical checks:
First, look up the registration or aircraft type on your booking, then check a site like Aerolopa or the airline’s own wifi page, which usually names the provider, whether Viasat, Intelsat, Inmarsat, Panasonic 2Ku or Starlink. The words Starlink or Ka-band are good news. The words Air-to-Ground or ATG mean keep expectations low, and remember ATG does not work over water at all.
Second, check whether the airline differentiates pricing by aircraft. Airlines with mixed fleets often charge the same price on a 5 Mbps ATG plane and a 150 Mbps Starlink plane, which is the worst value in aviation short of airport bottled water.
Third, on the day, ask for the latency rather than the headline speed. A speed test that shows 40 Mbps with 700 millisecond latency will feel broken for anything interactive, while 15 Mbps at 40 milliseconds feels fine. Satellite orbit, not bandwidth, is usually what makes airplane internet feel slow.
Working practical rules for a long flight
If you need to work rather than browse, the difference between a survivable session and a wasted one is mostly preparation. Download files and offline copies of documents before boarding, because even good connections are lost for ten to twenty minutes around taxi, climb, and weather. Prefer asynchronous work: email and document editing sync fine at high latency; video calls do not, unless the aircraft is LEO-equipped, in which case calls are genuinely possible, and many airlines now explicitly permit them. Expect dropouts over polar regions, high latitudes and deep oceanic gaps even on satellite systems, because beam coverage thins there. And treat any deadline that depends on a connection at 38,000 feet as an optimistic one.
The five-year picture
The direction of travel is not subtle. Starlink and its coming competitors, including the aviation-targeted layers of other LEO constellations, are on track to equip the majority of new wide-body deliveries, and retrofit programs are moving through legacy fleets at pace. The airlines that caused the most wifi misery over the past decade were mostly those locked into old ATG and Ku contracts, and those contracts are expiring. By the late 2020s, the expectation that a full-flight video call over the Atlantic works is likely to be normal on new aircraft and a lottery on old ones.
Until then, the one-sentence version: check the aircraft, not the airline, before paying for wifi, treat LEO-equipped flights as fully usable, treat ATG flights as messaging-only, and never schedule anything irreversible around a connection you have not tested at altitude.
