FYI A number of us purchased these promotional fares out of JFK in F booked as A. I was on the line with UA 1k today and she informed me of a schedule change. My January 2003 JFK to SFO had a five minute time change to 8:40 AM. The computer put me on the 7:00 AM outbound flight 0003. The same thing happened with my March 2003. So if you are outbound JFK to SFO on flight 853 you will probably find your flight and departure time changed. Please check.
