We use T-100 traffic data and DB1B fare data from the U.S. Department of Transportation to identify patterns and effects of entry by network carriers and low-cost carriers in non-stop U.S. airline markets. For the sample period from 1996 to 2009, we find that entry activity of low-cost carriers...

The article studies the evolution of the U.S airline industry from 1995 to 2009 using T-100 traffic data and DB1B fare data from the U.S. Department of Transportation. Based on a differentiation in market size and major players, entry and exit, concentration, fares, service, costs and profits,...
