Fare Class XV?
 

Can anyone explain fare class XV to me? I haven't seen this show up on my CO account summary before, but it's there from my most recent flight, IND-IAH-MSY-IAH-IND, all 4 segs EUA's.

upgraded V class.

X-anything is an upgrade of that fare class to first. You'll only see it on your OnePass statement, not on the boarding pass or reservation online.

You may already know this part, but in case not, here goes: on your online reservation, an EUA shows up as fare class R (First), even though you paid for coach. Your purchased economy fare class then disappears, never to be seen again. So, if you want to track your paid fare classes, wait for your OP statement, or print your itin right after you book, before any EUAs happen. (Or, as is more frequently the case, if any EUAs happen.) :(

Then why on a recently flown "Z" fare does my co.com "recent activity" page show me as having flown a "XZ" segment? Since Z is discounted first class, I don't see how I scored an upgrade, as you describe above.

As an aside, I was not credited the 150% elite miles that I ought to receive from a "Z" fare. Has this happened to anyone else out there? If so, any suggestions toi get my extra 50% EQM's?

My preferred class of service is XX, my favorite beer too! :p

I just flew Z class DEN-IAH-BOS-EWR-DEN and I too did not receive the additional 50% EQMs. I just placed a call to OP Svc Ctr and they are looking into it. Try it, couldn't hurt.
