ETA: Since you are in the DFW area and the airport of choice is most likely DFW... consider flying Southwest out of Love Field. They have some fantastic airfares, especially if you book on the "sale" days. Another positive about Southwest is that if you miss your flight or something comes up whatever.... as long as they know before you check in and get on that plane, 100% of the funds go credited to your account. The funds in this account CAN be transferred to someone else in the family if needed and they are good for 1 year from the date of the cancellation. Those funds can be used for ANY flight ANY where they go. American and other airlines will give you credit BUT you have to use that ticket to go to the same location within a year and it is not transferable.
Also book hotels online with the hotel to get good deals. If you ever need help, let me know. I did ALL of the travel planning and booking for hubby for 30 years. I'll make sure you learn the ins and outs of the travel portion.

Original...
I have a Bank of America and a Chase card used for business ( I put my personal things on is as well but those are minimal) These cards are always paid in full before any statement is cut and never carry a balance. So if you are looking interest and fee wise, I have no clue because I have no interest and no fees.
That said, both of these cards offer cash back. I'd MUCH rather get $$ back onto my statement or in my savings. Both of my cards are business cards so they might have different rules but I can easily get $1200 CASH BACK a year with each card. I just got $615 back on Chase this past month and around Christmas, I will cash in again. That is $2400 FREE money back in my savings. I refuse to pay a yearly fee.
Back before we did cash back we did airline miles and it was fantastic then, however, the airlines (and hotels) have made it SO hard to use it is just not worth it.
Another card we had was by Citibank Driver Edge and you accumulated cash back towards a car, any car you buy. The deal was, make you car deal the best you can and once you are done, THEN, send the paperwork to Citibank and they would cut you a personal check for the amount of benefits you have accrued. We got $2500 back AFTER the purchase of a new car a few years ago. This was so long ago that I don't know if this card is still around.
All that said, you know me on this site as saying debt is evil.. IT is.. However you go about it, just watch the rules and make sure it is paid in full so you have no worries about extra charges.
I realize my cash back is probably higher than the norm and that is because it is a business card and utilized for business which can generate more expenses than a normal household.
