Oneworld says it will be the first global airline alliance to complete the roll-out of interline e-ticketing between all members of the group.
As a result, Oneworld customers will be able to travel with one electronic ticket throughout the combined network served by the alliance’s eight member airlines - American Airlines, British Airways, Qantas, Cathay Pacific, Iberia, LAN, Finnair and Aer Lingus - and their 17 affiliates.
Together, they fly to 602 destinations in 136 countries worldwide.
Finnair and Cathay Pacific are the latest partners to offer the service, and the remaining three members - Aer Lingus, Iberia and LAN are expected to roll it out in the next month.
