I think you got a great offer. I haven't seen many people on here get their fee waived in the past year. I called yesterday and asked for the retention department, the girl was puzzled.. then called it another name. They told me they couldn't do anything since I haven't been charged the actual fee yet. But I would have taken the fee waiver, but I guess you could use it with a pay by miles and get $120 off. When I called they were trying to tell me that I would be getting the $99 companion voucher, but from what I've heard they are really hard to use.

$70k in charges, with at least a 3-7% fee they charge, they've made at least $2,100 minus whatever they pay delta for the miles (110k miles).

I wonder if you could get away with asking for a fee waiver on an upgrade to the Plat Delta card, which is $150?
