I was "Grabair" sponsored a few years ago and I remember being pushed to the back of the queue when it came to flying so that "airline sponsored" guys could go first.
This was happening to another guy who was "self sponsored" and he ended up complaining to Tim "nice but dim" SharKland.
Also remember an AirUK sponsored guy being given 3 days notice to get out of his room in the local halls of residence so that a new BA cadet could have it.
Took ages to complete my non approved IR there due to; lack of instructors,
aircraft going tech,
airline sponsored guys getting preference,
simulator being upgraded at short notice(after driving up to CFD to find all slots on one sim cancelled without notice)this went on for weeks instead of days.
Stories at sCabair----too many to mention?
