I am not big on airline credit cards but Delta has/had a promotion that you could easily accumulate 75,000 miles quickly when getting a new credit card. Sometimes they will have a mailing for this and other times I have noticed it on their site or an agent would mention it I was able to use miles (45,000) last year for my trip. I don't currently have one of their credit cards but would consider one if I knew I was going to travel and they have the same 75,000 offer.
