IATA Airport Code: BKK
Airport Tax: 700 Baht (30 Singapore Dollars)
Internet or Wifi: Expensive over 150 Baht per hour. No free usage.
City to Airport Taxi Fare: 200 Baht to 400 Baht
Airport Express Bus: 150 Baht (infrequent 1 per hour, 4 destinations)
Airport Link (Train): 45 Baht (new in 2011)



Summary: The hefty airport tax is certainly not budget-travel friendly. Most other countries in the region charges much lower airport tax. Even Singapore charges less. In Malaysia, there is even a discount for using budget airlines such as AirAsia since they will use the
Low Cost Carrier Terminal (LCCT). The LCCT provides free internet WIFI usage. In BKK with the
absurd 700 Baht airport service fee? No! There is a gimmicky 10 minute free wifi coupon at the Information Counter which will take you a long walk to get to, and then when you're connected, the speed is slow and the 10 minutes are used up within - ha - minutes!
There is a food court at Level 1 with prices starting from 35 Baht to 100 Baht. Average 50 Baht meals.
