BA and Iberia began imposing a £8 charge “per fare component” on GDS bookings from November 1.

In a statement, Travelport confirmed that BA and Iberia content “will be available to all customers”, including its “rich content, branded fares, fare families and multiple ancillaries”.

However, Travelport said businesses without a private channel agreement “will be subject to the airlines’ surcharge”.

Travelport added that it was “working to develop NDC [Iata’s ‘New Distribution Capability’ standard] connections and is on track to achieve Iata Level 3 status in the coming weeks”.

Paul Broughton, Travelport’s UK and Ireland managing director said: “All our customers will continue to benefit from Travelport’s tools beyond booking capability that enable workflow automation, change management processes, multiple content integration, robotics for fulfilment and other vital services.

“We are confident that the evolving technology and commercial changes in airline distribution strengthen the value of our travel commerce platform as a dynamic aggregator working at unprecedented scale and speed and with unmatched reliability and cost," he added.
