TS (not BS) are you a recruiter for a widebody airline though?
You might not hesitate to put TP pilots in a 777 or a 380 but the insurance premiums will surely go through the roof.
If your theory is such a great idea why aren't the Global airlines implementing this fantastic idea? The only reason EK is implementing this strategy and Emirates alone is because they can't get pilots to come and work for what they pay. Pay us what we are worth and the staffing problem is fixed overnight and you won't have to hire TP pilots.
