Rumour has it that a good many of Astraeus' B757/767 rated pilots already have their name in the hat for jobs with Zoom UK.... indeed rumour has it there's enough of them to crew at least 1 (and maybe 2) more B767.
This is hardly surprising when you think that the basic salary for a Captain with Zoom UK starts at £75k (and add on to that the 'duty pay'... which then probably takes the package to over £80k pa).
Nb. Zoom UK's basic salary alone is actually a few thousand £'s more than the top salary available following years of long service at Astraeus.
4 of Astraeus' senior Captains have resigned to go to Zoom UK - and to my knowledge 2 were not B767 type-rated (alebit I suspect they are likely to be a rare exception to the rule of 'type-rated only' wherein in they all have a host of other skills and are already well known to the top-level management at Zoom UK).
