I just found that there is a cheaper ticket hidden under Grab a Deal at MAS website.
I also learned one thing. Do not use FireFox to making the booking if you planned to pay using Maybank2u or CIMBClicks. The payment page requires a pop up window, but FireFox will not show it and you will be just waiting and hanging there forever. If you refreshed, it will then show an error page.
Use IE and you will be fine.
