Hi pilotboy, the full service is available to you on the plane, but you will find, the F cabin is in total darkness 10 minutes after you hit cruising altitude and everyone has already changed into their pjamas and the main requests are for extra pillows and blankets. When you arrive in the Bangkok lounge, if you are hungry, let the supervisors know, they will sort something out for you. Conversely if you would prefer to sample a selection of entrees on board the cabin crew will assist in arranging this. The table is large and they can display it all for you. Don't worry if you do not feel like eating or drinking, you will find the majority of regular late night traverllers don't either

If you like a good night's sleep, you can request they wake you at the last minute, before landing.
