In my personal opinion, along with Singapore Airlines and British Airways they are the best airline I have ever flown. Super food, loads of legroom, and Dubai is a fantastic airport. I have also done the DXB-BKK leg - I believe the flight leaves Dubai at something like 2.30 in the morning, so the unfortunate side-effect is that you will be totally shattered by the time you have finished spending one hour at Bangkok immigration, and you might be unable to cope with the heat and humidity until you get some rest. My advice is therefore to get into an air-con taxi ASAP, get to your hotel and sleep it off, unless you can sleep on the plane (I never can)!
I used to think the brain is the most fascinating part of my body. But, hey, who is telling me that?
