I was just told to go to Toronto next week. The Delta flights are mostly sold out from MCO, so I checked Northwest. They have good flights available, with "YUP" fares going up, which is an automatic FC upgrade, and H fares back, which are coach. YUP fares are available for the return, but are $400 more than the H fare. If I buy an H fare, will I be able to request FC upgrades on NW the same as on DL?
