When GF is cheaper than BF the website returns the Global First fare instead of the higher priced BusinessFirst fare. If your BusinessFirst search is returning an A fare this is probably what is happening. Sometimes if Z and P fares are not available the A fare will be lower than the J, C, or D fare.
