I think Flybe might be surprised at how few people are out there. I recently received an email thanking me for my application, but to now enter it via a CTC site. This is despite the fact that my application was over 12 years ago! If their application database is so out of date, they might find there are few applicants (apart from recent CTC guys) to fill the seats.
Anecdotally my current employer is struggling to find and retain FOs to fill 737 and 757s.
