Sounds like he is a coffee with his Baileys rather than a Baileys with his coffee kind of guy. Why the heck not.

The 767 with 4 rows is an upgrade IMO over the 757, but both are good. A 767 with more than 4 rows is a huge upgrade, but don't get your hopes up. I just prefer the 2 aisles of the 76 series plus the cabin is much bigger and feels better to me on a long flight. I think that is why I don't care for the upperdeck on the 744's.

I wouldn't nomally say this, but as someone who does not travel frequently and since this is a pretty long trip, make sure you drink plenty of water. It is easy to get dehydrated when drinking and traveling for 8 hours in a low humidity environment.
