I’ve been told that Business Premier Lux suites which are not sold (as a ‘seat selection’ to BP passengers) will be made available to other BP passengers in the following order:
* upgrade bid (so it appears that these bids will be available as an option even in BP)
* recognition upgrade certificates (see above)
* complimentary bump-up for any EP1 in business class, followed by Elites and then Golds.
