said July traffic rose 9.4% from a year ago.
The Dallas-based airline said it flew 5.2 billion revenue passenger miles during the month, while its load factor, or the proportion of seats filled, rose 1.9 points from a year earlier to 79.4%.
The news comes on the heels of an agreement Friday with the airline's flight attendants, and less than a month after a surprising earnings shortfall at the longtime Wall Street favorite. The company's weak second quarter, which was blamed on rising cost problems, came just ahead of the surprising departure of CEO Jim Parker.
On Monday, Southwest fell 22 cents to $14.25.
