I like NWA better and right now they even have some offer on their first page of web site about getting 7k on your sign up for Wp FF account! read it there. I find they have shorter hold times and i have had more success in mile redmeption, and ease of web site use, but thats just me, maybe.

The only thing I dont like is the guy's voice who is there when you are on hold. he sounds kinda stressful and when you are on hold with an airline, its bad enough.

I also like NWA because if you cannot find your award flight on their site, the phone people MAY still have some seats on that same itin, and while you have to pay the $15 fee, it could be worth it there. I KNOW united does not have this little thing, and I dunno about DL.

DL can be good, however, if you are a member of Singapore Airline's krisflyer. I used to submit miles from DL and United flights to them and get credit on their airline, which is part of Star Aliance. So its one way to consider it ...
