I just want to chime in in sympathy with the OP. At 6'3", which is hardly 6'7", coach seats are downright crippling. At 6'7"? I just can't imagine. You'd have to hope and pray that some kind flight attendant would have mercy on you and just bump you up to 1st.
You know how, when you're a little kid, you say "If I were president, I'd make every weekend a 3-day weekend"? Well if I were president, the first law I'd pass would be to make a mandatory seat pitch of 38" in coach.
