Finally some reason. Yes, a seniority based system that allows senior Airbus Captains to transfer to the 777 before an FO does an upgrade on it. Likewise senior FOs get a transfer before the ankle-biting SOs do an upgrade.

There is only one organisation that should be championing this and it is the organisation you hopefully pay your subs too. But don't hold your breath. The silence is already deafening with regards to Staff Travel....
