Airline Traffic Comparison, June 2009

Major airlines are those with an average of 100 or seats or more on regularly scheduled flights flown during June 2009. Regional carriers are those with less than 100 that are certified exclusively as Chapter 121 carriers (and fly only scheduled flights with 10 seats or more). Flights are counted by total segments flown, so a flight from New York to Los Angeles with a layover in Denver would be counted as two departures.
