Hi Dan,
I signed up trough the link you posted to gain silver status with BMI. I flew yesterday on US Airways from Los Angeles to NY and recieved my two free bags and priority check in etc. However , this morning I recieved an email from BMI stating the following:
Dear Chaya
We're pleased to see that you recently joined our Diamond Club frequent flyer programme. However, I'm writing to you because unfortunately the link you used to join was an exclusive by invitation only offer and as noted in our terms and conditions was non transferable.
Regrettably, we will not be honouring the Silver status, and over the next few days your account will be downgraded to Blue status. Our decision is final, and we won't be entering into any further correspondence on this. On a positive note though, our frequent flyer programme is one of the most generous programmes around, and you only need to earn 16,000 membership status miles to earn a Silver membership. When you fly with us, or any of the Star Alliance airlines, you'll reach Silver status in no time at all. You'll also have access to all our offers and promotions, as well as being the first to hear about our great sale fares. We hope you'll still enjoy the benefits of your Diamond Club membership.
Regards
Keeley Downing
Diamond Club Manager
I just wanted to let you know so that you can warn anyone else who signed up.
