US Airways, City continue debating PHL expansion plans

The debate continues between US Airways and the City over whether to expand PHL runways and rebuild most of its air field. Are these necessary improvements or costly enhancements that won't relieve air traffic congestion and chronic delays? The story has been covered extensively by Inquirer reporters Linda Loyd and her successor on the airline and PHL beat, Paul Nussbaum. The most recent exchange of opinions between US CEO Doug Parker and Mayor Nutter is in a Sunday Inquirer story, reposted here to create a longer-lasting archival record for easy reference.
