OK I'm starting to get confused about this CPU and auto-splitting of PNR thing at check-in. My husband and I are flying EWR-SFO-OGG round trip in a month and by that time he will be silver and eligible for CPU on SFO-OGG legs. We are both on the same PNR. So my questions are as follows:
1. So when he checks in and says that he would like to be considered for upgrade that is when our ticket will be split?
2. There is no way to guarantee being upgraded together?
3. Where will I be on the upgrade list relative to him?
Currently at a month out our SFO-OGG flight has 0 booked in first so hopefully our chances our good going there at least (5 booked out of 16 coming back), but I'd love some clarification.
