Thanks for the responses!
Not to bring it off topic, but another UA
question related to the international 763s: Are there any differences in the F and J seats (old configuration)? That is, for the planes that have not recently been refurbished with the new F and J seats, from looking at photos the old seats look pretty similar. Any differences in terms of space, comfort, etc.? (SeatGuru doesn't say much about it.)
