How Cirium measures airport and airline on-time performance

Cirium has a proven track record of reporting on OTP results for more than 15 years – the longest of anyone in the industry. We try to stay true to the industry definitions of OTP and make sure we represent the data in a transparent and consistent way, but criteria has evolved over the years.

Report calculation – Airline calculations

Key evaluation criteria
Available Seat Kilometres (ASK) — the number of seats available multiplied by the number of kilometres flown — captures an airline’s total production in terms of their total passenger carrying capacity and distance flown.

Flights
The total number of flights flown — captures the airline’s total volume of passenger flights flown.

Seats
The total number of seats flown — captures the airline’s total volume of seats flown.

Regions Served
The total number of regions served by an airline — captures the airline’s global prominence across report regions. An airline is considered to serve a region if it operates one (1) or more flights per day to or within that region. An airline’s home region counts as one of its regions served.

Actual Gate Arrival Time (AGA) Coverage
The percentage of flights in Cirium’s database for which the AGA field is present — ensures a minimum data quality standard required to evaluate the airline’s performance. Airlines can boost their coverage by becoming a Cirium Data Supplier. Find out more at

Completion Factor
The percentage of flights not cancelled — captures the airline’s ability to complete their flights as scheduled.

Report calculation – Airport calculations

Each month Cirium reviews the total number of flights in a given month
(approximately 3 million) for every airport globally in an ordered list, then looks at where the percentile demarcations fall. For the annual OTP review, we take the total number of flights in a given year for every airport.
Airports are selected based on a combination of factors.
