That's was a really good question...
Does anyone else have anymore info on how COPA and Delta miles tie in? For example: I am flying on COPA this week and I used my Skymiles number.
The last time I flew COPA I joined One Pass because someone said that I couldn't get credited. When I got to the gate, the COPA GA said that I could use and get credited to my Skymiles account.
I am just curious if anyone else has any info or if the OP would like to share any experiences he picked up along the way. Then again, if they are joining SkyTeam, I won't have to think about this for long.
