I heard the move-up program is changing from a supervisor this morning while getting my move-up processed. I didn't get anything official, so i could be wrong. For those that are not familiar - the Move-Up is US Airway's same day stand-by program. The rules were vague at best - but allowed you to move up to an earlier flight for $50, waived if you're elite. What counted as an earlier flight? Is it by departure? or was it by arrival time? so if I was on a 9am BOS-PHX and i wanted to take an 8am BOS-LGA-PHX, was that allowed even if the LGA-PHX got me into PHX later? What about if I was on the 8am BOS-LGA-PHX and wanted to take the direct to arrive earlier? In the past, with a friendly agent, you could get most reasonable changes accomplished with a move-up. This was very helpful to add segments, or to fly on a flight that had first class availability. Now, the rules are stricter to get move-ups processed. You cannot change your connecting airports without having the ticket refared. So, if i was flying on the noon BOS-PHX, i could still move-up to the 9am BOS-PHX, but i could not take the BOS-LGA-PHX without having to refare my ticket. It's an unfortunate change - but likely not the straw that broke the camel's back. Other carriers (like UA) have much more restrictive same day change policies (orig fare class needs to be available).
