Eastbound, I'm no expert on contracts, but just be advised that you are in the drivers seat before you begin the contract, not after you sign on the dotted line.
Just a couple of questions, who will you actually be getting paid by? Will the local taxes be paid?
International school tuition is approximately $1000 per month, per child. A decent two bedroom apartment runs about $1000 minimum in Saigon, probably higher in Hanoi. Traffic is tough in both cities, the airport is a 45 minute drive from Hanoi proper.
A320 salary here is approximately $117,000 USD (includes housing) the first year without the travel allowance. About 12K higher on the second year.
Will the aircraft be "VN" registration, just curious.
Good luck, D.L.
