Between the 2004 until about 2014/2015 the low cost airlines recruitment pattern was either low hour cadet on a SSTR and flight pay only contract (eg: Easyjet Flexicrew), or experienced time on type 737/320 pilots. Frequently low hour cadets were recruited on such schemes in preference to experienced turbo-prop pilots, instructors and even jet experienced (non 737 or 320 rated). Low hour cadets (from one of the big three) paying for the rating on flight pay only deals are extremely cost effective, so as Airlines look to save costs you may find that the recruitment policies begin to mirror that seen prior to the 2015 recruitment boom.
