AS don’t allow you to change the number to a non-AS number.
One advantage of using your AS number is that you earn EQM on the award flight. The downside…. likely no status benefits if you have status in another program.
Thanks,that's annoying. I am booking for whole family and they don't even have AS number but all with BA. One is BA gold so would like to take advantage of this.
