Sorry for bringing back this old thread, wasn't sure where to ask this.

I had an IAH-LGA-IAH ticket, outbound in Y(K fare) and inbound in F (A fare). I called in this morning to upgrade the outbound, and it went into Z, but oddly the return also became Z. Will this cause any problems for me? I think A is a higher fare then Z, right? Why do you think this happened? Just the best way to refare the ticket?
PQM/PQD earnings look to be showing up right though.

Thanks!

Also I never received a new eticket, and the one in manage booking on the website still shows the old fare classes. does this mean it wasn't reticketed properly?
