Yes but 200 hour cadets turn into potential captains. The problem for Ryanair is not only losing Captains but it's also losing 3000 and 4000 hour Co-Pilots who have good training records and deemed suitable for command upgrade. Lots of these guys and girls are electing to join the likes of Norwegian,Emirates, the other airline that we can't name, Jet2, Aer Lingus, and a few have joined Easyjet.
The real problem as I see it will be when Norwegian and Emirates start recruiting at the same time.
