Point 4. In which direction? Up or down?
Given that most UK recruitment in the last year has been almost exclusively "cadets" and most future openings at other UK operators will be going the same route, there are a significant number of experienced pilots unable to get anywhere as a result, I would therefore imagine that the level will be up.
I have in excess of 8000hrs and a lot of heavy jet time, including the 744 and I have been sitting at home for the last 12 months whilst 200hr guys off the OAT conveyor belt have been getting what few jobs are available at the likes of J2 and Ryan and Flybe (and paying for the privilege) I very much doubt that I am the only one.
I'm sure that there will be plenty of people "having a go" with 1500 hrs on TP's and good luck to them but GSS will probably have a largish number of people with a lot of relevant experience to choose from. I know that the aviation world has gone collectively crackers over the last year or two but I reckon experience will for once count in this instance. I certainly hope so.
Unless of course, everyone else has gone to Emirates.
