Hi, WW apparently stated that with IAG buying Aer Lingus, EI would rejoin One World – which translates to EI flights generating BAEC tier points. However, there is precisely no mention of just when this is going to happen on the One World website.
Presumably, this is all part and parcel of integrating EI’s commercial operations, passenger route planning, cargo, finances etc. into IAG’s overall planning process. After the BD acquisition, IAG ought to be relatively skilled and fleet of foot around such integration processes.
