2 for 2 so far this year. Most personal travel is WFBF on a Z fare and OPM flights are usually booked last minute and I upgrade with miles on segment that’s usually booked solid with paying fares:. CWA <-> MSP. CIU<-> MSP is always a comp upgrade. DLH-MSP can be tough but it’s such a short fight.
3/1 ORD BOS booked in C+ upgraded at 24 hr window GM with Amex Reserve
