Whether a flight has Starlink depends on the aircraft, not the route — here's how to get a real answer in under a minute.
It's on your booking confirmation, boarding pass, or airline app — two letters plus 1–4 digits, like UA123. The digits alone work too; the checker assumes United.
Open the flight checker, type the flight number, pick your travel date, and hit Check. The answer comes straight from the live database — no signup.
Within about 2 days of departure, United Airlines has assigned an actual aircraft, so the answer reflects the WiFi provider United Airlines itself lists for that aircraft on united.com. Further out, no aircraft is assigned yet — you get a probability built from which aircraft recently flew that flight number, clearly labeled as an estimate.
Aircraft swaps happen up to the gate. Check again the day before you fly — the page updates continuously as assignments firm up.
A verified yes means we observed the assigned aircraft's status directly; a probability means no aircraft is assigned yet and the number reflects that flight's recent history — not a guarantee. Some United aircraft still carry older WiFi systems while the rollout continues, so "has WiFi" and "has Starlink" are not the same question. Wondering about the price? Starlink WiFi is free.
