Hi
Last year i was in same boat with Air NZ and QF UK - I looked at salaries promotion and destinations - QF UK was far better - with Air NZ too much seniority at QF none so promotion quick.
At QF we fly to 3 destinations - and already they get a bit tiresome after 6 times in a row to HKG - (however i have saved money and an extra 600.00 a month on top salary is good !!!.) Air NZ only 2 destinations.
VS has more varied destinations where Air NZ not salary at Air NZ more than VS but staff travel is very poor compared to VS.
PLus the AIR NZ new uniform is shocking !! - VS very nice.
Its a hard one but I feel I made right choice.
Oh - yeah - VS train on, 3-4 aircraft ??? Air NZ only 1 ha ha .
Well done and good luck.
