Wow - this is just a mess. Way to think through the eventual fallouts before launching this AA... ugh.
So - I'm now caught in a loop. I joined BE donkey's years ago, and have used it for my 2 person LLC. When the "multiple fliers" requirement kicked in a few years back, we made it fine, but via the independent contractors I would hire on for jobs, and us booking their travel (and forcing them to fly AA against their Global Services protests!)... I guess if everyone has to have the same email domain, AA wants me to let the half dozen electrical engineers I have forced to fly American every time we travel LAX-LHR in paid J, to go back to their beloved United!
Seems the new program is only for companies that exclusively travel in-house employees on jobs!
<looks around at the VERY different corporate landscape of today than American executives must think exists>
Moreover - as has been pointed out, BE never needed a FEIN. Tying the registration to an FEIN and legacy BE number is fine... but the "name" we used on our BE when we registered is not the exact name that is on the FEIN - so of course we're in a blackhole of AA IT... would it have killed them to roll over companies automatically, and then force the FEIN update? (And offered support so we could work through the errors?!)
What a stupid and shortsighted move.
