Mark Gale, the airport's chief executive, said: "We continue to work with all our key stakeholders and airline partners on both short-term and long-term projects aimed at enhancing the airport's operation, which in turn keeps PHL competitive to serve our world-class region. We believe that we share common interests in finding an acceptable solution for all parties."
US Airways, backed by other airlines, went public in January with opposition to a new runway along the Delaware River on 212 acres now owned and operated by United Parcel Service as a large airfreight facility.
At the time, US Airways said it did not oppose the entire expansion, but rather the proposed runway, which airlines contend would not greatly alleviate delays because Philadelphia's airspace, shared with New York, is so congested. Nor would a new runway necessarily attract more international service, airlines said.
The city contends the runway is important to reduce chronic delays, especially in inclement weather, and to accommodate future growth. The expansion would create thousands of temporary construction jobs.
US Airways spoke out after the city demanded that airlines sign a 15-year lease agreeing to pay for the runway.
In a 159-page regulatory filing, US Airways said that the expansion over the next 13 years would "result in huge cost increases for airlines serving Philadelphia" and that "expenditures have already begun."
US Airways' hub in Charlotte, N.C., is its largest, with 595 daily flights. But Philadelphia, an international hub with 429 daily flights, generates more revenue.
The city has estimated the total expansion cost at $6.4 billion. Airlines, which would foot much of the bill in rates and charges through debt service on airport revenue bonds, say it could cost $10.5 billion.
While no city tax dollars would be used, the Federal Aviation Administration permits a $4.50 passenger facility charge on each departing traveler to defray costs of airport improvement projects.
