We just came back from a vacation in Kota Kinabalu, Malaysia. When we arrived in the airport, we took the airport taxi because we felt safer that way. There is a booth inside the airport where we paid for a coupon costing RM 45 (about $10). On our way back, the taxi costs only RM 30. When we asked the taxi driver, he said that it is a flat rate of RM 30 whether you are going to coming (airport – city trip). That was also our experience in Ho Chi Minh, Vietnam the other year. And then it occurred to me that also here in Manila, the airport taxi is more expensive than the regular taxi.
