Spartacan, Maude Charlee's words of caution are, sadly, quite accurate.
A couple of years ago Flybe did take on a batch of part-time remotely rostered pilots. The guys worked a 70% 7 on 7 off pattern, and this was a good situation for all concerned. The Company were able to plug the ever-increasing number of holes in its establishment plan around the bases, and the pilots themselves were able to live where they wanted to live.
Unfortunately, along came a new Ops Director who couldn't see further than the end of his nose, and, without considering what a benefit it was to have these flexible assets, decided that they were enjoying too much of a 'special' deal, and told them to accept a permanent base or leave. As Maude Charlee said, half of them chose to use the Flybe rapid revolving door. Of course the establishment holes still remain, so the number of nightstops are still the same, but over a 7 day period they now have to use several different guys from several different bases who would rather be at home, rather than a remotely rostered pilot who made the choice to be there. For some reason Flybe seems to enjoy pi*%ing its pilots off, and often deliberately finds a way to do it. When airline crew became affected by the Working Time Directive, the 7 on 7 off changed to 5 on 5 off.
The other downside of being part time at Flybe is that there is no part time protocol. Full time = 22 days per month, so part time is a proportion thereof, and whereas the average part time checkout operator at your local supermarket will work a percentage of the weekly full time hours, a Flybe part timer will generally work slightly over and above the number of hours that his/her full time colleague will during his/her days on. That's because the higher number of days off between working periods means FTLs are never breached, so they take advantage of this and hammer you! I basically worked full time hours for 70% of the salary, and for this reason part time pilots are appealing to the Flybe bean counters. BALPA is currently working on this issue, but there's so much other crap to wade through first.
Your decision to proceed with caution is wise, and quite frankly unless you live 5 minutes from a Flybe base the square bond makes it a no-brainer. There are many within that believe that the bond would not stand up to a legal challenge, but nobody's elected to go down that route yet.
Edited to word things a bit better
