Looking for a good airline rewards credit card. I have an AMEX delta but have not been very happy with it.?

I am planning on switching to something else. Anyone have any good suggestions?

Thanks

Don't cancel your Delta, send a secured message via Amex website or call customer service to convert your Delta to another Amex product like Amex Blue as mentioned.

This way you don't get hit with another hard inquiry, will keep the original account opening date and you'll have a card you can hopefully use.
