I do fly budget for the most part because that's all my budget can allow lol. It's not too often I fly though. Last budget flight I went on they canceled one day, I had to scramble to move my hotel around (was going to Mexico, first and only time out of the country) then the next day they canceled it again! I was unable to scramble dates around the second time. So my "budget" airline cost me a whole day of vacation that was already paid for.
If I can spring for it I like Southwest. At least they don't make me pay for bags lol
