1.) For the last round of recruitment, all bases were open. The vast majority got what they wanted.
2.) I fly from an airport in the south and am engaged only 3 times a week. 85 hours per month over the summer doing charters can come very quickly. A couple of Canaries, several Turkeys and a few Greek Island trips has you up to 85 hours in no time.
3.) Everywhere. Most I believe are ex EZY Flexi or Aer Lingus. Only about 15 cadets.
