Wow, didn’t realize KLIA also offers fast-track services. I guess where there’s demand, there’s supply. I’ve always found KLIA pretty efficient usually through in 15–20 minutes.
We’re still contemplating whether to book fast track for our trip next month. Feedback seems mixed, anywhere from 15 minutes to two hours

. A friend who travels there often suggested just turning up, checking the crowd on the day, and if it’s bad, slipping $20 in the passport and handing it to the guard. I was pretty shocked, but they claim it works much like fast track. Anyone tried this?
