How the figures were made
The table puts routes in the order of their scheduled flights. It does not put them in the order of their on-time shares, and it assigns no cause.
A route is one direction between two airports. Flights are the scheduled flights of reporting airlines in the BTS files. A route has a change when it had 360 flights or more in the 12 months before.
A program makes this page from the BTS files with fixed sentence rules. How the figures are made. BTS and TSA files.
