Obviously this is not good news, but none of it is actually new. Flybe have already forecast a full year loss of around £15m for 2012/2013 (the figure being announced today is for the first/traditionally strongest half of 2012/2013). The four aircraft being parked has also been known for some time.
It's also worth mentioning that the internal email I received today regarding the half year results makes no mention of job losses or jobs being at risk. Of course the impact on staff doesn't necessarily mean job losses, it could be just another year or two of no bloody pay rise.
Time will tell. Lets hope the government see sense and stop flogging domestic passengers with APD - this hits Flybe hard.
