Mate, if you're going to pose a question in an argument, at least make some bloody sense.
Now how many people here think that flying onboard a flight where there is possibly 5000 hours between Capt and FO? Or onboard with an experienced crew with possibly 25,000 hours between Capt and FO?
Think what?
Secondly, of course a captain "so-called" or otherwise will likely lose his command. DEC schemes in the UK are usually recruitment exceptions done with the acquiescence of Balpa to allow for growth where current company experience does not allow.
I know Captains with less than 18 months in the left gain a DEC at another outfit and I also know of Captains with several years left seat experience go to another company in the right seat.
