Hey guys, I was hoping to get some advice for an app run. I got 50k miles last year when I got the Continental card, and I got 30k AA miles on each the VISA & AXP AAdvantage cards.

Unfortunately, I just used both of these to book first class flights (cost the same as economy) for both my mom and I for this summer. So, since all my miles are done, my mom has said she'd be okay with me doing an app run using her name.

I need to know which cards would get me miles through signing bonuses that would be most useful for flying between the following locations:

DFW -> Minneapolis -> Norfolk, VA -> DFW

Any ideas?
