I was perusing AmEx's cards and saw they have a new Delta card, the Blue Delta AmEx. It's got no annual fee and I think it would be a good addition to the wallet. The current public offer is underwhelming on the bonus - 10,000 miles after $500 spend, but I thought it might be better through a referral link. The Gold and Platinum are both double the public offer through the referral links at the moment (60k vs. 30k and 70k vs 35k respectively), so I thought maybe the Blue would be the same way. Anyone have one of these cards that can give me a referral link?
