I'm headed to Brazil (GIG or GRU, schedule hasn't firmed up yet), which is an overnight flight ex ORD or IAH (~10 hours). I can fly on the 777-200 in the 2-4-2 arrangement, or on the 767-300 in the 2-1-2 arrangement. I'm 6'2", and hoping to sleep. Traveling alone for business.

Which config is better for one of my height, all things considered? Note that the single seats on the 763 are all taken already per the seat maps, so I'd be in one of the outboard pairs.

I'm sure this is answered elsewhere, but I'm in a bit of a hurry to book the tix on short notice, and am hoping someone might be kind enough to give me a quick answer.

Thanks,
Jeff J
