My Experience
Having sent absolutely no emails, I found myself upgraded to Ambassador Gold Status today.
I had changed my alliance to Delta before signing up for Ambassador.
No kit yet, but there is an authorization on my credit card for $150.00.
To the person above who got charged $100.00: That seems to be the renewal rate. Have you been an Ambassador before?
I await my kit and hopefully, 25,000 miles, even though DL really made me severely unhappy last week on my way to a funeral with respect to their handling of preboard status in ATL and DFW.
