One caveat. The seats on this flight are standard F seats, like those on a regular domestic flight. They do not recline to a nearly flat level and do not have leg rests, so comfort may be an issue on the 6 hours each way. Granted the F seats sure beat coach, but they are not what one thinks of as F or J seats on a 767 or 777 to South America. The advantage is that EUA's apply to these flights, so you do not have to burn miles for an upgrade.

I agree with the rest of the comments.
