VS-LHRCSA,
yes, the new temps will be posted onto 'A-division' (767;777;747) for the duration of their contract.
personally, i am of the belief that all the redeployed regional ground staff who take up these temp postions at WW LHR will be offered permanent positions on this same fleet at the end of their contract - and quite rightly so.
most of them have years and years worth of service under their belt and deserve to be looked after.
as for the rest of the temps (i.e. external recruits) i don't think that they will be let go. i'm sure that they will be offered LGW after their contract expires.
whatever you decide to go for - good luck. you will eventually end up where you want to be. some of you will just have to be patient.
it took me years and years to get to where i am now - and it was well worth the wait.
GOOD LUCK.
