It'd be a start if BA/IB/EI were all fully in Amadeus Altéa. Wish I knew why IB was hanging onto Resiber, and EI to ASTRAL. Get on with it!
And Vueling is on Navitaire (which is an Amadeus low cost subsidiary), Level built their own system but I think it's now swallowed into Navitaire. Astral is allegedly vastly cheaper to operate so EI don't want to give it up (and Iberia hated being on a bit of FLY for a while at LHR). Moreover I bet that Air Europa - the only IAG airline on Altéa apart from BA - will be forced on to Resiber!
