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.
