If you travel at all, a Chase Southwest rewards card is where it is at, if you are near a SW airport.
My wife and I use ours for *every purchase we can* (1 point per dollar) plus I booked hotels, rental cars, and airline tickets for work and personal travel on it for 3x points.
We have hit "companion" status, so she travels for free with me, if I book a ticket. I pay for my ticket with points, she flies free - we haven't paid for 2 R/T tickets in a few years. We accumulate points faster than we can use them.
With COVID, there has been no travel, so we are now over 250,000 points. That covers trips to Boston to visit our daughter, Hawaii next year (hopefully), Cabo to see my father, etc, etc.
Worth looking into, if cheap travel is your thing.
