WW - Jet2 will continue to do 70% for as long as they can get away with it, make your own mind up on how this year's recruitment went! As has been said many times, everyone who joins on 70% find themselves upgraded to 100% within months. This looks set to continue for as long as the airline expands (a good while yet).
I heard a few months back (even before the crisis) that next year's intake is likely to be mostly non type rated due to the pool of rated pilots drying up.
Jet2 are in the process of setting up an in-house TRTO. Sims are being purchased and installed at Multiflight LBA. Once it's up and running, I presume bonded ratings might follow.
