How we calculate On Time Performance

On various pages of our website, you will encounter a metric widely utilized in aviation and other forms of transportation known as OTP (On Time Performance). We believe that providing this metric assists passengers in planning their trips and exploring alternatives before purchasing their flight tickets.

We calculate the On Time Performance for all flights and airlines, when we have enough data to do so. In certain instances, it may not be feasible to accurately compute the On-Time Performance for a specific flight or airline due to inadequate or non-representative data, which could result in misleading conclusions.

Our calculation of On Time Performance and delay information solely relies on arrival times. This approach is chosen over calculating departure delays, as we consider arrival punctuality to be of primary concern to passengers.

The On Time Performance displayed on our website is calculated as follows:

  • On Time: Flights that arrive within 15 minutes of their scheduled arrival time, or earlier. In the absence of data for a specific flight, we assume the flight arrives on time, to avoid penalizing airlines for data unavailability.
  • Moderate Delay: Flights that arrive with a delay of 15 to 30 minutes.
  • Significant Delay: Flights that arrive with a delay of 30 to 60 minutes.
  • Major Delay: Flights that arrive with a delay exceeding 60 minutes.
  • Average Delay: The average delay is calculated by considering flights that arrive early as having a delay of 0 minutes. Early arrivals do not contribute to reducing the average delay calculation
