Personally with the current training load I don’t think they will have a choice. It will be 747 Capt and FOs only. Under a RIN there is no return of service on a higher type, so Captains close to 65 can RIN to the 380 and there is nothing they can do about it except VR them, start their training and waste the resources, pay them gardening leave. As usual a decision was made to get rid of the 747 at short notice after planning was working on probably another 5 years. It is and will be chaos for the foreseeable future IMO.
