I just came back from Los Angeles to Luxembourg on Cargolux 744F LX-OCV. The upper deck on all our 10 aircraft is equipped as follows :
Cockpit (of course), behind that on the starboard side a little galley and 2 10-men liferafts, on the port side the emergency exit with the slide. Then on the starboard side you get have the door that leads to the ladder down to main deck, opposite on the port side is the lavatory. Then you have 6 Business Class-like seats (just as shown on Chris Coduto's photo) posted by FlyVirgin744, one couple on the starboard side, 2 rows with 2 seats each on the port side. At the end of the upper deck is a little door that leads to a small room with 2 bunks for crew rest. The 744F has 3 passenger windows on each side of the upper deck. As you see on Chris's picture, the second row on the port and the row on the starboard side have 2 windows each, the third window leads into the crew rest compartment.
"Passengers" on these flights are usually deadheading crew members, Cargolux employees on business or holiday travel and cargo attendants (e.g. for horses). It is not possible to buy a ticket for these flights.
Service is minimal as there's no flight attendant on board. The passengers enjoy a cold meal while the crew gets warm meals, the reason for that is that it is too dangerous for the passengers to operate the oven.. they could burn down the aircraft by putting plastic plates in the oven etc.... there are snacks, sandwiches and cold and hot drinks available. The crew is usually very open-minded towards aviation-interested passengers so that I could enjoy a jumpseat on most sectors.
All in all it is a real fun to travel on Cargolux
