Today the Government has tabled a Bill in Parliament to amend the Malaysian Aviation Commission Act 2015 (MAVCOM) to give more power to MAVCOM to regulate unfair practices of all airlines flying out from Malaysia.
The explanatory statement of the Bill states:

It is overdue for the govt to regulate and stop the hidden charges imposed by airlines. They are too many charges on top of the actual fare. If you go to the website of airline, your fare may be RM500 and you have to pay for food, check in baggage, seat and etc. The total may cost you more than RM700 in total. Soon they will also impose fees for using the toilet or breathing the air in the aircraft. MAVCOM must stop this nonsense. Make sure that all airlines have to advertise their all in fare. The current trend of add on costs are unacceptable.
I wonder which airline gave the lunch meeting to MPs. Why is the airline so interested? Worried that they cannot have hidden charges after this Bill is passed!
