For several months now we have been haggling with USAir over a cancelled flight and poor customer service in Philadelphia, PA. They cancelled the flight based on air traffic control putting our flight in a waiting status but say its still not their problem they cancelled the flight. Passengers at customer service that evening swore and caused scenes with different agents but we refuse to step to that level. But those passengers received free lodging while we had to pay a lot for a room based on low supply and high demand. Their customer service continues with lame apologies but no real action. We will refuse to fly USAir and want everyone to know their shady practices.
