So the real issue, is that I'm booking through a 3rd party website. I'm using AMEX travel, integrated into Concur. I can find a DL reservation in Y/B/M, but the last segment is always operated by KA. Or I can find a Y/B/M on KA, but operated by Delta.
I am so screwed!
avidflyer: you don't think a US to Asia flight is worth the miles to upgrade to BE? Sleep is important to me, so I really want a lie flat or something with a good recline. I'm PM on Delta, so I can get the Premium economy for nothing, but, is that what I really want?
