Our only alternative is Pittsburgh Airport and our only option is USAir at this point. After 20 years I have to say DO NOT take USAir from SXM thru Philly. It always arrives late and you are stuck in Philly until the next morning. Charlotte is way better for a return flight. Unfortunately this year b/c of pricing we are returning home through Philly...wish us luck we won't miss our connecting flight to Pittsburgh.
