After reading this thread I decided to check our reservations. The confirmation code they had sent no longer existed. I went to website and the flight # from RDU to CLT had changed but the time was the same. DH called US Air and they had put us on a later flight out of RDU and we would have missed out connection to SXM by an hr. We would have had a 23 hr layover in CLT. Hopefully we will be OK now.

We did not receive any email or notice of change and if I had not read this thread I would not have checked our reservations. We would have missed a day in SXM and a lot of extra expenses. Thanks to this group for sharing their experiences. It certainly helped us out a lot.
