Codeshare Upgrades
I am a CO platinum living in Houston. I am about to purchase a IAH-DTW-SEA-ANC-SEA-MSP-IAH ticket for only $300. This will be on a NW ticket; to/from SEA will be on NW; SEA-ANC-SEA segments will be on Alaska Air. Is there any reason to expect a platinum upgrade on the Alaska Air segments? Logically, I believe this should be the case, but I am actually dealing with 3 different entities here. Assuming that all parties want to do the right thing, there is a good chance for confusion, especially in a situation like this. Any input will be appreciated.
Thanks,
pjc
