As an, all too frequent, passenger I've come to loath my fellow pax. I used to love flying, but once I got a job that entailed a lot of flying, I've grown to hate it. Based on experience (am clocking around 200K miles/year), made the decision never to fly long-haul on my own time, but if forced then only in business.
Enter darling wife, whos best friend recently immigrated to another continent. Wife insist we go visit her forthwith, and I check mileage balance. Unfortunately, had just spent most of the balance flying our families up/down for visits, so not enough miles for 2 c-class tickets. Told her we'd have to wait, but she wanted to go NOW. Fine, I said, then either you go economy or we pay for one c-class ticket (which was around 4K Euros). Wife has a hissy fit, I stand my ground. End of story? She went to visit her friend, I stayed at home.
Never, ever, will I fly long-haul in monkey class. And seat reclining is just one of many reasons.
