Removal and addition to HHA
I have a HHA which includes my wife and 4 children in it.
My in-laws are going to HKG later in the year in CW. They have never flown before and are therefore not members of BAEC. If I add them to my HHA I can benefit from the Avios they will earn but I only have 1 slot left as I am already using 6 out of 7.
I read on this thread that only 1 change can be made every 6 months.
I have a family trip booked in April which will earn Avios for the whole family and the inlaws travel in October.
My plan is to remove one of my children after our trip in April so I can add both the inlaws. Would I have to make these changes simultaneously so it counts as 1 change?
