I thought that it was before only with A3 issued tickets, but now seems to be also for OA. Or maybe I remember it wrongly..
That must be out of date - from the days before OA and A3 effectively because the same company. Now all OA issued tickets are also issued on 390 stock. And, in any case, I don't believe OA offer any flights with C class so it's not relevant anyway
