Spirit Airlines data for the five quarters from the fourth quarter of 2007 to the fourth quarter of 2008 are not included in the May 6, 2009 release because the airline is updating its reports. Atlantic City, NJ, is not included because Spirit operates more than 90 percent of the flights there. The Atlantic City average fares in the July 23, 2008 press release were based on incorrect data. The data available on the BTS website for the second and third quarters of 2008 have been revised from the data released on July 23.

Average fares in cities in which Southwest Airlines has a large market share may not be comparable for the period before 1998. Before 1998, Southwest reported all passengers as one-way passengers with one-way fares. Beginning 3rd Quarter 1998, the Department of Transportation removed the reporting exemption and Southwest began reporting complete round-trip journeys. Southwest's reported fares roughly doubled after the reporting change.
