I wasn't expecting the new program to be quite as good as the old Worldperks, but there is quite a difference from not quite as good to the steaming pile we're being left with. This change is the last straw for me. I barely make elite thresholds as it is, so I can't afford to blow miles on free tickets, so their only use for me was international upgrades.
International upgrades on B or Y fares lose a lot of their attractiveness without the 50% bonus. I was actually about to do a B-fare vacation to SIN mostly justified by making plat based on that this year, but don't think I'll be able to get it in before March 1, so I think all my and my company future travel is just going to be on a cheapest/convenience basis. Maybe I'll try a match to AA.
Have enough miles for two WBC tickets to anywhere, so probably do that with the wife and be done with Delta.
