AA OW award: voluntary downgrade to Y then standing by at gate for biz on BA/CX?
I have an AA-issued OW award ticket in business, and I need to change dates. Date changes are free, so no problem there.
Problem is there is no business available on the dates I want, so I am thinking about voluntarily downgrading to Y to travel on the dates I need. Now, the question is, will BA or CX or IB allow me to standby for a business class seat if there is availability on the day of departure?
Thanks.
