First time in Thailand, really enjoying it so far. If I have a flight leaving from DMK on AirAsia on a Wednesday afternoon and I have luggage to check, how much earlier should I plan on arriving at the airport? I don't mind sitting in a lounge to wait if it has some food and drinks, and it looks like there are some options in Terminal 2. From a different thread it seems like three hours is too much time. Is two hours enough?

From Lumphini Park area, would Grab be a good option to take to DMK? That's what I used when I arrived from BKK. Thank you!
