Card/Rewards Suggestions???
 

Really need some help on what to pick. Trying to find an airline and hotel rewards program, along with a few cards tha fit me. Here's a personal breakdown so far:
I'm 19, I have 4 cards (1 falls off the 5/24 rule in march)
I have the discover it, a fee harvester (it was a rough time, had fees waived and it sits at a 0 balance just to add on to credit age), a Chase Freedom and a Best Buy Citi Premier rewards card. Yes I know half of them are useless.
I am able to reach almost any min spend requirement by paying my tuition, which is reimbursed every semester. I live in Texas and my closest airports are DFW and DAL which fly a lot of AA and SW, and quite a few united. Had I not been under the 5/24 I would've done the double app on the SW card for companion pass, but that's not an option unless that deal stays around for another 6 months or so (highly unlikely). Was also looking at the Hyatt card as the point redemption on signup bonus alone could net me at least 8 nights, however I'm not sure if it's the best long term value or not compared to other hotel rewards/cards. Any input would be appreciated and I'm sorry if this is hard to follow as my situation is probably different than most. Thank you!
