US Airways said on Wednesday that its July passenger traffic increased 4.9 percent and a key revenue measure climbed 8 percent, a sign that airlines are still benefiting from fare hikes earlier this year.
The airline set a July record for "load factor," or the percentage of seats filled on the average flight.
"Our July consolidated (mainline and Express) passenger revenue per available seat mile (PRASM) increased approximately 8 percent versus the same period last year," President Scott Kirby said in a statement.
Passenger revenue per available seat mile rose 8 percent. The July increase was slightly better than the 7.6 percent increase for the April-through-June quarter.
US Airways said paying passengers flew 6.21 billion miles last month, up from 5.92 billion in July 2010. Excluding regional flights under the US Airways Express banner, the company's main unit, US Airways, saw traffic rise 5.1 percent.
Passenger-carrying capacity including US Airways Express rose 1.9 percent, to 7.08 billion available seat miles, a measure of one seat flown one mile. Excluding Express, capacity rose 2 percent.
With passenger traffic rising faster than capacity, average occupancy increased to 87.7 percent from 85.1 percent.
