The prediction for UA1377 is based on the aircraft actually observed or claimed to operate this route, not a generic fleet-wide guess. Based on the airline's published installation figures for the aircraft types observed on this flight: A21N 20 flights at 88% equipped; A321 1 flight (no published figure). Weighted by observed flights, the expected share of equipped aircraft is 88%. 5% of observed flights were on a type with no published figure and are left out.

No prediction can guarantee a specific aircraft. Airlines perform last-minute equipment swaps for maintenance, operational needs, or schedule changes — meaning a Starlink-equipped tail can be replaced by a non-equipped one on the day. A score of 80% or above means historical data strongly favours Starlink on this flight, but it is not a guarantee. For the most reliable information, check the airline's gate display or app on the day of departure.
