What's more relevant is not the time to downtown Philly (seriously, do they think business travelers and condo-dwellers want to fly into ILG instead of PHL in order to get to center city Philadelphia???) it's the time to get to suburban Delaware and Chester counties. Shoot, ILG is actually closer to Lancaster and Reading, PA than PHL airport is. THAT's where ILG should throw some marketing cash. I don't think someone in center city Philly who can hop on a SEPTA train for $7 and be at the airport in 30 minutes is really going to mess with getting to an airport south of Wilmington.
