Im a member of BA Exec Club. I was recently downgraded to silver from gold even though i had 1715 tier points for the last year. I flew cathay throughout last year. What i would like to know is weather Marco polo will be better for me since i fly 4 times a year on cathay(DXB-HKG-LAX-HKG-DXB) and (HKG-CGK-HKG) on business class or should i enroll on American Airlines. Help??????
