I'm doing my best to work on my father. He flies at least two flights on United a year and never earns miles, even though he has a USAirways account with a number he doesn't know. I called US to get the number for him and they had his old office address on the account and they moved last century! He never signs up for hotel programs and is missing out on points and miles. He also writes me emails saying "I'm going to xxx next week, please get me the exit row".
