How we calculate this

Flights per day
The number of flights (code-shares counted once) that entered Airportia's schedule data with a scheduled departure on that UTC day. It is updated every hour, so the newest day can still grow, and it includes flights that were later cancelled. Totals include all tracked flights, including cargo.

Coverage follows the schedule feed: some regional airports and airlines are missing or report few actual times. These are Airportia's own figures, not official statistics from airports, airlines or regulators.
