The idea of upgrading people on 320 might be plausible from operational point of view but not realistic. It doesn't really matter which airplane to be upgraded on it only matters how quickly, isn't it. The problem is the queue on 320 and limited sim slots resulting in backlog of about 50 guys, if I'm correct. Even though the latest OPS review states ongoing 330 upgrades, we shall see. There's a widespread problem within industry called shortage of everything sims, slots, TRI etc. Again why not to outsource it? Why not to upgrade on 777? If QR fills the right seats on 330 & 777 with cadets then the senior guys won't see their upgrade in due time. Well, it only confirms the notion among them.
Don't take it personally take it on the rocks!!!
