I'm of a similar height and you're leaving out the third option. Fly and suffer. Sit like a GSD with hip dysplasia.
But in all seriousness, you're not used to it by now? Paying more for clothes that fit properly, a car that fits without hair brushing on the headliner or knees in the steering column, air mattresses, real mattresses, tents, bicycles, shoes, etc.
It's true - I'm used to having to pay more for the same and for putting up with a certain level of expected discomfort. I just find with flying there's not a good alternative option. I can shop around for a car that fits me in the right price range, I straight up just don't have a choice with flying.
