I'm 6'2" and I can't stand the horrible short seats on the 767-400 and 787. It's an embarrassment and I don't say that lightly. There's no comfortable way to use those seats as beds unless you're in the handful of bulkhead seats. The 777-200 3-class is really sad for personal space, but it's a better seat in every other way (for me, a tall person). It's long, and has a softer cushion. Game over. Screw being closer to your seatmate, there's nothiing worse than an unusable $7,000 business class seat.
