Hi everyone, I currently have an excellent credit score (so no concern there) and primarily use a Citi DoubleCash card for all purchases. I've noticed the 2% cash back on everything, doesn't seem to be everything (only "eligible purchases) and I was wondering if there was something better.

I currently have:
Citi DoubleCash
Chase Disney Visa
76 Personal Card (I get gas from there as it's the same as paying cash and get money back)

I travel maybe once per year on either United or JetBlue. My goal really is to be earning the most back in terms of statement credit or points that could be used toward a free airline seat. I'm pretty new to this whole thing so I was hoping some experts could give me a personalized recommendation. I've been reading a lot of blogs and am just unsure what is best for my particular situation.

Thanks in advance!
