A new airline information system being launched by the International Air Transport Association should result in passengers being given a wider range of choices when they book tickets.
The association hopes to trial the "new distribution capability", or NDC, later this year in places including Australasia, which it says will bring airline systems into the internet age.
Older systems were not flexible enough to take into account the wide range of new airline products, said IATA's director general and chief executive Tony Tyler.
"By bringing modern merchandising capabilities to the selling of airline products, we will enable much richer comparison shopping," he said.
Features could include Wi-Fi availability, duty-free shopping, specialty food and beverage services, anything that adds value to a traveller's experience.
