Happened Tuesday night (AF 689 ATL-CDG). Monday afternoon all was good, seats booked, readyfly, meals selected, even called AF a few days prior to request childs meal. Tuesday morning and I go to check in online and it says "This flight has been cancelled at your request, if you did not do this please call". I called and within 15 minutes AF says VS screwed up. Call VS and after 40 minutes get an operator that says he can't do VS awards and transfers me but it drops me instead. Call and another 45 minutes and CS says it was AF that screwed up....40 minutes late they say all is well, same flight, still J cabin but seats will be provided by gate agent. Concerned got to airport over 3 hours before departure but it didn't help. Check in agent said economy, gate agent said economy. Called AF, called VS. It didn't seem to matter. The gate agent said reissue ticket as Z class and make a note but VS said they had no option but X or O. Finally just said I'll buy upgrade, but at this point an hour before take off two seats in J couldn't be co-located to accommodate our 8 year old.

It was bonkers having a (albeit Delta) gate agent argue with a VS service rep over speaker. They both said each other was wrong. For what it's worth manager came over and was quite rude, eventually they just said we have to go and straight up left, no to return until about an hour before take off. 10 year anniversary for my wife and I. She's in tears, my kids in tears, I'm just shocked that literally no one could tell me who I could talk to in order to straighten it out, despite both my bookings online with VS and AF showing biz. Again my return shows biz as well, but AF has already informed me this will be rejected at 24 hour check in mark, yet no one can tell me how to resolve.
