BA and Iberia have no further obstacles to their combination. The two oneworld carriers will have their path to merger smoothed by shared use of the Amadeus reservations platform. This will surely now confirm that Iberia will also migrate to use Altea Inventory and DCS from Amadeus. The structure of the new group allows for more airlines to be added in future. Willie Walsh is said to have a shopping list. Most of the airlines rumoured to be on it are also Amadeus customers. This is unlikely to be coincidence.
