The aviation industry in Pakistan stands on several pillars including regulators like the CAA, airlines both government-run and private, general aviation, MRO services, and airports. However, Pakistan lacks some key aviation services like regional airlines, dedicated air ambulance services, and more fixed-base operators. Only a few of Pakistan's 46 airports are profitable and there are just 4 airlines serving the country's population of over 200 million people. The national aviation policy has issues like allowing older aircraft ages and high taxes and duties that hinder industry growth.
