Note all BA inventory around late 24 June to ~am 25 June will be limited to fully flex buckets only.
As part of our ambitious £7bn transformation programme, we are updating and re-platforming our Revenue Management system.
As a result, from 24 June 2025, we will be moving from evaluating our availability from Point of Sale (POS) to Point of Commencement (POC) - this move aligns with NDC and direct channels. These system changes allow us to continue to deliver advanced modern retailing for NDC connected partners globally and further enhances the breadth of customer benefits when shopping with us.
As we move to our New Revenue Management System, there will be a number of hours where inventory may be restricted. We are hopeful that there will be minimal impact to you during the transition period, which will commence on 24 June at approximately 22:30 (BST).
During this period, availability will be degraded, with only the highest booking classes available in each cabin (F, J, W & Y). Once the period of restricted availability is removed, it will then take a further 2-3 hours for all flights to fully optimise. This timeline may differ slightly dependent on how you connect to British Airways Inventory.
