I phoned to put a mileage plus number in to a friend of mine's United reservation - only to find that there was one there already! I wonder - she is part of a 34 person group!</font>
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 #.
