You’ve no reason to trust me. No you can’t get training out of flying Red Air other than airborne time itself which would be better served flying as Blue. You simply can’t get the required ‘ticks’ when flying Red Air. That’s not open for debate.
People are leaving, that’s the point, and of those people leaving they have been asking for follow on tours on the FL and are not getting them for various reasons; entirely valid reasons for the majority.
