The Productivity Commission has found airports aren’t ripping off airlines who use their runways or travellers who pay up to $17 to park near their terminals.

The report comes as a blow to the QANTAS and Virgin Airlines groups, who claimed they were being gouged by the airports and wanted a new body that could rule on disputes.

The commission did raise concerns about how much taxis, buses and hire car operators are charged to use access roads, and questioned why Brisbane and Sydney airports had some of the highest international access fees in the world.
