Hello everyone,
I've tried looking over the forums to answer my questions but there is so much information its hard to find info specific to me. If my situtation looks familiar and you can point me to a thread that is similar, please do!

First I'll try to list information yall may need:
I currently do not fly often, perhaps once a year, all within the US. In the future I'd like to fly more often and maybe venture outside of the US some.

I currently fly out of Dallas,TX. *Edit* Airline and Cabin do not matter, I usually try to find the cheapest.

*Edit* I'll spend around $35k a year.

Ok, so my situation is pretty simple. I've recently discovered the benefits of rewards on credit cards and decided it would be a great thing to get into to allow me to travel more often. I'm looking for a card that gives me the most points or miles just for using it. I have discovered the following cards may work for me and would like some input or other suggestions.

Mariot rewards Visa[/URL]. 70k points for spending $1k in the first 3 months. 1 point per dollar.

American Express Premier rewards gold card. 25k points for spending $2k in the first 3 months. 1 point per dollar. 2X points for gas and groceries.

I'm leaning towards the Chase card but I'm not sure if im just being taken in by their marketing or it really is the best card for me. Also, I'm sure I could be missing another card I could benefit from.

If I need to provide more info, I'll be happy to.
Thank you VERY much for your time.
