Monday evening I head for the airport to catch my flight to Istanbul. Trying to do it most affordably. Get someone to send to 1 Utama bus station- FOC. Take Skybus to KLIA2 – RM15. Take KLIA express to KLIA from KLIA2- RM2. If you have the time, this will work. It took me around 1 hour 45 mins to get from I Utama to KLIA. It was 8 pm so traffic was still a tad heavy. I guess you can make in faster rike during non peak hours.
