Nothing new here relative to what's already been reported, but another data point. Opened an new account in July 2011, deposited $100K (did not cycle). Got 50K AA and Delta, then withdrew all but $500. Just did the AA 50K for existing accounts and deposited $100K. Got the "type of account is not eligible email". Called and they said that message can mean lots of things. They reviewed my account and said the message was because I got the AA offer last summer, but that it had been more than 12 months so I was eligible again.
I was reminded that I needed to keep the funding in the account for 6 months
