Any aircraft with the original generation engines on is a CEO, not only those with the space flex cabin or a rearrangement to get somewhere close to it. CEO has nothing to do with the interior. All 129 BA Airbuses that are not NEOs are therefore CEOs, all with variations of the V2500 engine, except 1 which has CFM56s.
