Flying tomorrow, SFO to CPH, Two of us have Premium Economy, trying to get Business. Minimum bid is $300. I bid for just over $500. Not sure going to get it, on ExpertFlyer, went from three pairs of seats available, to five blocked, and one taken.
What does SAS block seats for? Becaue they are taken by reservations, but not selected by the flyer yet.

What are my chances, we are still about 31 hours before departure time tomorrow?

Thanks for your thoughts

EDIT: Called SAS, since I was confused about Check-In times. I read that check in is 30 hours, except for flights TO the US. So, since my flight tomorrow is FROM US, (CPH), then I thought 30 hours. SAS said I was right, check in should be 30 hours, and he wasn't sure why I could not check. So, I asked question about Business Upgrade, he said there were 10 seats empty on Business. So, if that is true (ExpertFlyer says seven seats available or blocked), then maybe my chance are good. Stay stuned.
