You are absolutely right but you don’t know how many of those RYR pilots don’t make the cut. Hundreds apply and very few make it to the carriers you mention. Does not make them special at all. There are so many people who try to leave RYR when they can….not as many as other airlines.
The training at Ryanair is great but the name is not so much. Other airlines recruitment teams know how basic the Ryanair recruitment process is for cadets.
