A late, it seems, welcome to the board!
"On another note, it is true that we benefit from our combined knowledge in achieving certain "legal" advantages that other travellers probably do not obtain. I am doubtful though that BA has an interest in removing those advantages, particularly for such a small group of people."
I'm sure on the whole that's true but it stands to reason that if loopholes were noted that could cause an unrealistic business disadvantage to BA/BAEC however small then it would also stand to reason for any employee to plug the loophole where applicable. I'm sure it's already happened in situations like the Tesco/BAEC points free-for-all.
