Does BA mind if you switch out members every 6 months as the rules say you can. I want to transfer some miles so my wife can use the 2-4-1 promotion and fly CW with my kids, but I dont want to not be able to use my miles for other members of our extended family. BA does not allow transfers from my Diners club points to any other BA account other than my own. What I plan to do is first get milage awards for extended family members, then form a household account with BA, then make my wife primary member. I then will then book our 2-4-1 tickets using our combined mileage total. Whenever I now want to purchase tickets for extended family members I will remove myself from the household group.
