On-time performance is for February 15 - April 15, and is provided by Flightstats.com. Figures are for marketed, or codeshare, flights: For example, if American Airlines advertises a fare for a flight that is operated by Delta (carriers often make such marketing agreements), and the Delta flight is delayed, that delay is reflected in the on-time performance ratings for both airlines.
