I posted a week or so ago asking if it would be OK to get a duplicate players card and have my girlfriend and I play at the same time to get to Chairman status faster while at the same time not being marked as advantage players and getting no-mailed -- or worse, banned/points confiscated/etc.
I read the details on the card they have at the rewards center and it says under general rules "Only members listed on a Boarding Pass account may receive information or engage in any transaction(s) relating to that Boarding Pass account."
So, that seems to indicate you should not play multiple cards at the same time. Unless a bunch of people say it's fine then I'm probably not going to do it.
One thing I did notice in the rules is that you can link two Boarding Passes together. When I asked about this more at the Rewards Center they said the accounts are still separate, but the points you can spend on comps are shared. It doesn't share status points though. The Rewards Center person said we'd still get individual offers and both be able to individually take part in giveaways and stuff. Would there be any reason to link or not link our two accounts together?
