Unless you can get a bulkhead on the 763, the sUA 772 will be better for a tall pax. The small footwells on the 763 are a problem in non-bulkhead seats.

On the 772, try for row 6 or 7.

I prefer Row 1 of the 763.

At 6'2" I think the 777 seat may be better because of foot room particularly if you have a large foot size. Depending on your size(width) you may find the 767 more accommodating because of the increase width of the seats. With my dimensions 5'8" and 200+ pounds I prefer the 767 seat and really enjoy the middle seat.

In any case if sleep is a priority and 767 middle seats are unavailable, I would opt for a window seat on either aircraft so you are not disturbed while sleeping. While some people find the footwell size on the 767 to be a problem at 5'8" and a 8 1/2 shoe size it has never been a problem to me.

Middle of 763--no climbing or being climbed over!

I'd go the 763. The seats are wider by 3". As already stated, the area around your feet can be tight.

Given your height and desire to sleep, I'd say definitely pick the 3-class 777. Some of the 2-class planes, the 767-300ER in particular, have a different seat design that has less length and less space for your feet to rest when sleeping. I find even the bulkhead of these planes, while having a very large footwell cutout unlike the rest of the plane, still have short length. The middle seat in these aircraft sounds great in practice, but they are extremely compromised as far as length is concerned. I'm 6'2" and I simply cannot lie flat or sleep in these seats. Further, I've had my drink spilled twice due to the tight aisles.

The 3-class 777 will have a denser cabin, but the seats are noticeably longer and IMO have slightly better cushions for sleeping. Both planes will allow you to collapse the armrests for more width, but the 777 seat is a smidgen less wide (I don't think it's 3" though).

One last thing - since the 777 is a 3-class plane, you can pay for an upgrade into F (or on the oft chance possibly be operationally upgraded), and that seat is the pinnacle for sleeping (they provide a mattress pad).

Thanks for all of the quick input, guys. I've 6-2 and have size 13 feet, so the tight footwells and shorter length might be a problem for me on the 763, and there wasn't availability in Row 1 or any middle seats.

Just booked ICT-ORD-GRU on the 777-200. 9A and 9K, but might switch to 6K on the return leg (UA shows it available, but our company's travel agent didn't).

According to UA, the 763 seat is 1" wider. The 772 seat may feel narrower because there is less personal space.

The cushioning is better on the 772. The lack of personal space can be an issue though.

I'm the same height and shoe size and can confirm that you have absolutely made the right decision (unless you happen to be a fetal position sleeper I suppose). the 747 and pmUA 777 with 2-4-2 seating are the way to go for you. Avoid the pmCO 764 at all costs - even the bulkheads.

Grab 6K. Much much better seat!

I think it really comes down to your sleeping style when comparing the sUA vs. sCO seats. I'm 6'6" and wear size 15 and I prefer the sCO seats (bulkheads of course, but even the "regular" ones). I'm a side sleeper, so the foot space doesn't bother me as much - but I do appreciate (and notice) the extra width.

I second this!! You'll def prefer 6K over row 9.

I did ORD-GRU earlier this year in 6A both ways. On the way down the IFE had some issues so during dinner service I moved back to 10A. It miraculously fixed itself after the dinner so I moved back to 6A. 6A was so much quieter and smoother (no engine vibration) than 10A was.

I was surprised as I've sat in row 9 before and don't recall the vibration. I think it's relative, so had I been in 10 the whole time I probably wouldn't have noticed the engine vibration, but after moving back and forth on the same flight it was very noticeable.

Disagree...I'm 6'3" with size 11.5 feet and I slept like a baby in the 764 bulkhead BF seat EWR--FCO in July.

Good points. I tend to be a side sleeper as well, and can't stand the pmUA 777 C seats...just feel too cramped, plus there's barely any personal-storage room.

In flying between L.A. and Fortaleza, Brazil in biz class next Feb/March, considering 777-200 through Houston and Rio or 767-400 through Newark and Sao Paulo. Former has 2-2-2 seating, latter 2-1-2. Latter costs a bit less. Leaning against the Houston-Sao Paulo option since that 777-200 is a 3-class and the biz class has 2-4-2 seating, with some seats facing backwards (wife would not want to run risk of having seat moved to one of those). Space counts more than sitting side by side to us. We have taken Delta biz class in 767s with truly lie-flat seats, and those were great, but currently United prices lower in biz (not first).

Any experiences with the two of these in regards to comfort and service? We have taken the 767 when it flew via Houston (I remember the 2-1-2 seating).

the 2-class 77E and 764s use the exact same seat so there's barely any diff in comfort.

i'm not a big fan of the 2-4-2 so I'd skip that unless the pricing is really in your favor
