What am I flying over on a US flight?
A US transcontinental flight spends hours over terrain with almost nothing under it: the Great Basin, the high plains, stretches of Nevada and Wyoming with no cell coverage. Whether there is a moving map in front of you depends entirely on the airline, so on a Southwest, Frontier, Allegiant, Alaska or American narrowbody, SkyDot is often the only one on the aircraft.
Hours with nothing underneath
New York to Los Angeles is close to six hours, and the memorable stretch is the two hours over the Rockies and the Great Basin. It is also exactly where a connected tracker struggles, because there is no ground network beneath you to reach.
GPS does not care. Your position comes from satellites overhead, so the map keeps moving over the emptiest terrain in the country as reliably as it does over Chicago.

The screens went from the aircraft that fly these routes
Widebodies kept their screens. A 777 or a 787 still has one in every seatback. But those fly the international routes — a transcon is a narrowbody, and the narrowbodies are where the screens went. American stripped them from every A319, A320, A321 and 737-800 in its domestic fleet, finishing in 2025, and Southwest, Frontier, Allegiant and Alaska never fitted them. United and Delta are the two that kept screens on many single-aisle aircraft.
Wifi does not fill the gap, and it is rarely free in the way it sounds. American gives it to AAdvantage members, Delta to SkyMiles members, Southwest to Rapid Rewards members — you enrol, you sign in, and your itinerary joins a marketing profile. United and Alaska still charge outright. JetBlue is the one that just gives it to you.
None of that buys a map. Pay for the wifi on an American 737 and you have internet in a cabin where the screen the map lived on no longer exists. The connection and the moving map stopped being the same purchase, and only one of them is still on the aircraft.
Questions
Do US domestic flights still have moving maps?
It depends on the airline. United and Delta still fit seatback screens on many single-aisle aircraft. American removed them from its narrowbodies from 2017, and Southwest, Frontier, Allegiant and Alaska never had them — those cabins stream to your own device, and the flight map is rarely part of it.
Does it work over remote areas with no cell service?
Yes, and that is where the difference shows. GPS is satellite positioning, so coverage over Nevada or Wyoming is the same as over a city. The map itself is already on your phone.
Do I need to buy inflight wifi to use it?
No, and buying it would not get you the same thing. Download the North America map pack on the ground and the whole flight runs offline — no session to pay for, no loyalty programme to join, and no screen needed in the seatback in front of you.
