AF upper deck

Can anyone tell me something about AF upper deck? I have never taken a flight other than in a lower deck. Is there any difference? I maybe must point out that I am not very much into experimenting. I like feeling safe and comfortable all the time. Any good points?

Hello. You really dont have anything to be afraid of. In the upper deck you have a rest area for about 15 people. There is relief crew up there. In other part of upper deck can be put about so many seating as for 75 troops. So you really can relax. Even more because there is less people and less noise. There is a plenty space to feel comfortable. Now this is very common thing and it is not at all some experiment. Have a nice flight.
