When I'm flying somewhere for work, I'm often willing to pay for an upgrade to business-class. It's not that I'm am opulent fop who deserves the best--I mean, I live in a motorhome--it's that I can't afford to lose two days of work while I'm on assignment. There;s just not enough space, with the width of my shoulders and my need to work on a laptop, to be productive when I'm seated in coach.
