Agree that it happens. But it doesn't feel right to go from best Comfort+ seats to the very back of the plane, with zero compensation or willingness to fix offered.

I never expect an upgrade from Delta. But once the upgrade is granted, I do expect that Delta won't downgrade me over a flight number change and then say "You have a coach ticket. Upgrades are not guaranteed." I also expect that Delta IT will maintain granted upgrades on schedule change Saturday. I don't think that's too much to ask.

Between that, charging me to SDC on an expensive coach ticket, and not allowing me to SDC for free on a domestic First Class ticket per the policy, I feel like Delta is nickel-and-diming a lot more than they did in the past. PM used to have some great value. It doesn't feel like it has as much currently.
