I had a flight booked using miles from PWM to ANC for my father and I...it was a 40k standard reward....I decided I couldn't bear that long in coach so called today to pay for a 90k first class ticket for us both....they refunded the 80k miles I had originally used and then only deducted 90k from my account (should have been 180)....when I look I still see us both on the ticket with confirmed seats in first both ways...did I just come out 90k miles ahead? will we have problems when the day comes and I try to check in? Is there a way to confirm that the ticket is 100% all set for us both?
