Trying to book a seat for baby on points in Flying Blue for a delta ticket, air france only show a choice to book award seats for adults or kids 2-11, is there an issue if i try to book the 2-11 with an earlier birthday? Alternative is to call and buy direct from delta and pay the full major cash payout, but anyone with experience as to whether delta would say the ticket is invalid if the birthday is 2 years ahead/wouldnt adjust it? (i posted this in the skyteam search tips thread, but maybe more appropriate here.)
