UA2666 delay history
How we count: on time means leaving or reaching the gate less than 15 min late. With only a takeoff time, a departure is late from 35 min, as takeoff comes after taxiing. With only a landing time, 1 to 14 min late is unclear and not counted. Cancelled flights are not counted. History, not a prediction.
