From my ten aircraft base there has been one - single - FO resignation to go to the Sandpit.
I detect a lot more interest in the impending BA recruitment though.
However, CTC still have a hold pool. Courses in New Zealand have been filled every month and some of the courses are quite large >14. The end result being a very healthy supply of replacement Flexi-cadets. It is highly arousing for the Beancounters when they replace an experienced SFO with a Flexicrew Cadet..
Fair play to CTC, they didn't let any of their hold pool swimmers drown and they seem to have judged the demand side of the curve well enough to avoid a shortfall in supply.
