Hi Shannon,
On the current UA website, there is a way to exclude yourself from the Complimentary Upgrade List. You can even choose individual segments in which to be excluded. So, if there's only "crappy" F seats remaining on the BOS-ORD part of a BOS-ORD-PHX trip, you can remove yourself from the upgrade list for BOS-ORD but remain on the list for ORD-PHX
Will there be such a capability on the new system?
Thanks.
