AirAsia has also list down the justification of choosing the site for the airport. Among them are:- Location - The new location is cost efficient, good connectivity to highways and railway lines, and a readily available land. The land is owned by Sime Darby. AirAsia also claimed that the land proposed by the airport operator, Malaysia Airports is unsuitable due to Express Rail Link height and power issues. The land is also has poor soil quality making it more expansive and time costing to develop. AirAsia claims that distance between both airport runaways exceed international standard of 2 km. Access - AirAsia claims that the new terminal has seamless connectivy via road and rail. Passenger Capacity - According the AirAsia, the phase 1 of the airport will able to handle 30 million passenger a year, and phase 2 will able to handle 50 million per year.
AirAsia on its website claims that building a second terminal building opposite the current one, as envision in the KLIA master plan was not possible due to Express Rail Link powers cable height issues.
According to a local business newspaper, AirAsia enjoys incentives such as waiver of all aeronautical charges except Passenger Service Charge, which is borne by the passenger expires in 2007. The incentive was given as a part of convincing AirAsia to move from Subang Airport to Kuala Lumpur International Airport. However, the incentives covers not only KLIA but all airports where AirAsia operated. Incentive covers waivers on landing, parking, aerobridge and check-in counter charges. It expected that AirAsia wants it own an airport to help better manage airport costs.

It also indicated that by having two (international) airports would mean duplication of services such as fire and rescue, air traffic control, immigration and customs, which in turn would raise the cost of air travel. Finally, the association cited potential problems in managing air traffic as the site of the new airport at Labu is too close to KLIA....
