I was cx HKG based
Hi! cyn_sou,
For you concern, money, as LHR based CX crews, it would not be much.
I can't tell you the exact amount, but I am so sure, heard from the old colleague based in London, they told me it was too little.
Especially, only flight to HKG, means you always stay in CX's hotel, allowance is not so much, and you stay far away from downtown... there is nothing much around the hotel.
If money is what you are looking for... it doensn't seem to be a wise choice.
If seeing more differences is what you are expecting, sorry, it's quite bored.
But, why don't you try and ask CX how's the salary? Then decide whether you go further with their interview?
