What is OTP
On-time performance (OTP) data is critical to understanding the performance of airlines and airports.
Across the aviation industry, an airline departure or arrival occurring within 15 minutes of the scheduled time is considered on-time.
OTP is a crucial key performance indicator for airlines and airports, it helps to gauge their efficiency and also has the potential to set them apart from their competitors.
Understanding the data
On-time performance data shows the percentage of flights that have departed (for airports) or arrived (for airlines) on-time.
A flight is considered on-time if it has departed or arrived within 15 minutes of the schedule.
The higher the percentage, the better the OTP score.
Cancellations are included in our data and are considered not on-time.
For an airline or airport's OTP to be published, OAG requires access to flight status data for at least 80% of all scheduled flights operated, and to be ranked they must operate a minimum of 1,500 flights that month.
