Dave Z: they seem to be updating the system all the time with new dates - as far as I know, if you haven't picked a date within 2 weeks of receiving the "congratulations, you're through Stage 2" email, they'll take you off the system. HR never seem too sure when new dates are added though, but I'd wait a week or so and check again. I'd definitely recommend a visit to an aerodrome and an area centre (as many before me have said, the chances of working at Prestwick/Swanwick are high, so it would be wise to see what they do over there).
Jack.raven: I now have no idea what's going on with start dates. At my stage 3 (end of Jan) we were told we'd be lucky to get to start in September/October, but to be prepared for December/January (not good for me)!! I speak to Hr a week later, and I'm told April full but July empty. I don't know.......
