AirlineGrades is not affiliated with the Bureau of Transportation Statistics,
the Department of Transportation or any airline. The record covers domestic
flights operated by carriers large enough to be required to report, so smaller
and charter operators do not appear. A grade describes how often flights on
this airline, route or airport arrived on time in the period shown — it is not
a prediction about any individual flight, and it is not travel advice.
