The fact that your assessment results expire after 11 months & you subsequently get booted out of the hold pool is plain(excuse the pun!)stupid. I completely understand why you have to wait 11 months before re-applying if unsucessful.
So if it's true that BA are considering extending the time allowed in the hold pool that is a sensible move. In times of penny pinching why spend time & resources interviewing/sim checking someone who has made the grade 15ish months earlier.
It's not as if you turn into a complete idiot in such a short space of time.....
