DALLAS -- Passenger flew fewer miles on Southwest Airlines Co. in August but they paid more per mile than a year ago.
The Dallas-based company, which also owns AirTran Airways, said Monday that passenger revenue for every seat flown one mile rose 4 percent compared with August 2012. That follows an increase of 4 percent to 5 percent for July.
Southwest said that traffic dropped 2 percent, as passengers flew 9.17 billion miles last month, down from 9.36 billion miles in August 2012.
Southwest and AirTran added seats, however, with capacity rising 1.4 percent. Part of that increase came from longer average trips -- up 4.8 percent, to 1,007 miles.
