Called to separate my/wife's PNRs so I could request complimentary upgrade on N fare, as my wife has no status (I'm PM). Phone agent took care of it quickly and said she'd send me an email confirming the change, along with my new confirmation number. Got the email later that evening, which showed me CONFIRMED into First w/o seat assignments on R fare. This on all 4 legs of trip (2x outbound and 2x return). Checked my wife's and she also is now confirmed into first w/o seats. Of course, I quickly assigned seats Anyone else ever experience this? Will it stick?
