I am flying US on Fri. I got an email about this multiplier promo for check in.
Will this be offered for all members in party?
Also, I really want to use my UA # to get Mileage Plus miles to help Qlfy for *G.
Should I check in as usual, change the FF# to UA at the gate? If multiplier shows up great, if not, still not a bad deal.
Additional data: We are a family of 3 on the US mastercard $99 tickets, if it matters
