The money raised from the sale of slots at LHR was in the region of £40m. Yes this was a significant sum however it was also roughly the same amount invested by the Walker Trust in order to simply keep the airline flying from 2001-2003. My understanding is that most of this money was used to repay the trust, however I do not dispute that the windfall from the sale of the LHR slots has significantly helped Flybe's 'bottom line'.
Compensation from the RJX was not as significant as you may expect, afterall Bae did stipulate that they would build the aircraft ordered by Flybe. At the time of the order cancellation the industry was on it's way down. It has been noted that the cancellation of the RJX programme was a blessing in disguise for Flybe as it meant money allocated to the fleet renewal could help shore up the airlines finances in wake of the downturn.
The sale of the CRJ's cost Flybe a small fortune! It certainly did not make the airline money. The associated crew training costs onto alternative types and the cost of ferrying the aircraft out to India cost Flybe an awful lot of money.
I accept that Flybe commanders do not recieve as high a jet wage as other airlines however the prop salary is amongst the best in the country as far as I am aware. The next plan is to replace the 146 but with what is anyone's guess. Initially it looks like the RJ100 may be likely with THY, Swiss and SN Brussells looking to get rid of theirs. 737/319 and EMB 190 are also on the cards.
