as a silver ua is the best compared to any other *a. e+ and the hope in h3ll you'll get a cpu. and to be honest, i'm 2/4 upgrading as a silver, canada-iah odds tend to be ^^^ for silvers
I agree with you here. Last week I was scheduled to fly YYZ-DEN-LAS but it didn't look like my upgrades would clear, so during OLCI, looked at the four other routing options UA was offering me to change to for
free (ORD, IAD, EWR, IAH), checked out the seat maps, and picked IAH. Sure enough, left with 2 empty seats in J so all silvers would have been upgraded.
