How does United Airlines define "on-time performance"?

United Airlines defines "on-time performance" as the percentage of flights that depart and arrive within a specified timeframe, typically understood as being within a certain number of minutes from the scheduled departure or arrival times. This metric is crucial for evaluating the efficiency and reliability of the airline's operations. High on-time performance indicates that the airline can manage its schedules effectively, leading to increased customer satisfaction as passengers can expect their flights to operate as planned.

This definition is significant not just for operational assessment but also for evaluations against industry standards, as many travelers prioritize punctuality when choosing airlines. The focus on departure and arrival time is essential because it directly impacts the travel experience, influencing connection times and overall travel plans for passengers.
