United's computer, and the computers of most major airlines, compare the FF number entered into the PNR with the name on record for that #. If they don't match, the computer doesn't accept the FF# into the record. Even a single letter mismatch in the last name will result in rejection of the FF #.</font>
I beg to differ on this point. Several times last year I had my TA purchase tickets on United for relatives in order to take advantage of a corporate discount. In all cases, my FF number ended up on the record. Some of the passengers had the same last name, but some did not. United accepted the FF number every time. I had to call United to have them change out the FF number to the correct one.
