There will be no significant uptake and to think otherwise is dreaming.

Ask yourself where the type rated pilots would be found.

FAA increased the retirement age to 65. There is no retirement age in Canada. The only restriction in either country is the ICAO 'over/under' for international.

Most of the US majors have recently improved their contracts so why would a senior B777 Captain trade that to move to the Middle East and work twenty days a month. Similar story for eligible Canadian B777 Captains.

Sorry, I don't believe it will ever happen. The draw has always been from the low cost operators with non type rated pilots.
