You'll have an amazing time, and I'm excited for you!

For F:
1. The FA will help store your luggage for you, as it goes towards the floor and they'll keep it secured with two straps in case you're wondering where your carry on luggage goes. They'll give you a "beach bag" where you can put your clothes into when changing into pajamas, and I use the same bag to keep my pajamas to take home.
2. The treat basket is taken away at takeoff and returned when reaching altitude.
3. The air vent is a twisting motion to open and close, don't try to push the cap as it won't move.
4. If you like caviar, you're in for a treat; you can order more if you would like. Dine on demand concept, with whatever you want. Towards the end of the flight, sometimes they may run out of options, but I never had an FA say no. Excellent wine and liquor selection, and you if you like Cognac, you can blind taste the Hennessy Paradis vs Tesseron.
5. On the A380, the FA will ask you when you would like to reserve the shower suite for a time that you would like (usually I like to reserve 2.5 hours before landing). For the shower, it's 5 minutes of water time, but with light passenger loads, they will be happy to reset it for 10-15 minutes of water time if needed. They'll have a dedicated shower attendant to help if you need anything. Bathrooms are cleaned after each use, so everything is kept tidy throughout the entire flight.
6. You can go to the J bar in the back, and socialize or just relax. Usually the F bar is quiet. The F FA will let them know to serve you F alcohols when you are back at the J social bar.
7. I'm a big fan of row 2 for window seats, as I feel there is too much bathroom traffic for row 1.
8. DXB F lounge is huge! Some fliers lounge hop for different wine selection. I usually skip eating at the lounge, and prefer to dine on the airplane, as I feel the food on the plane is better than the lounge; which is opposite for some other airlines.
9. Can book chauffeur service.
10. If the cabin is not full, they can make your bed in the suite across from you.
11. Some F lounges allow direct gate access to your flights or some flights, such as in DXB and also at SFO (if you fly from there in the future).
12. Meet and greet service upon arrival at DXB; and they'll take you to the connecting flight terminal F lounge.
