What’s the next best airline?

So, I don’t fly often. Maybe 2-3 times a year but the entirety of my adult life I have flown almost exclusively on Southwest, especially now living in the DFW area for the last five years and being so close to Love Field.

That being said, for all of yall who fly more often then I do what do you think the next best option is? American is next “biggest” option for me but I hate DFW and the handful of times I’ve flown them there has always been some sort of minor inconvenience with every flight. I’ve got a few trips planned this year and looking for other options.
