The situation regarding schedule changes seems to have become worse--not better.
In the past you would get the message in RED that there had been a schedule change--you would see both the old and the new flight info. You then had to call SMS to get them to "clean up the record." This was annoying enough and my understanding at the recent RWT stuff was that the problem was being addressed and, even some indication, that it had already just been fixed.
Now, however, my wife had two itineraries where there were schedule changes and I had one--and the only way we were alerted to this fact was that we weren't even able to open the record--each time it would say the system was unavailable. A call to online support "cleaned up" the records and I can see them again. Still, this is a step in the wrong direction--not the right one--you couldn't even compare the old to the new.
I use Windows XP and IE 8.0.6001.18702.
