Volare 737 & Duh
In the 35 pages on this thread you would have answers to your questions many times over-its been covered time & time again. That is why you now get half answers & quips-people are weary of answering the same thing over & over again!
As far as a commuting contract goes-that is what most people consider it is- but depending on where you home is it may not be practical to get home in a 2 week break. That is for each individual to decide. You will have a confirmed return ticket anywhere on the VAC network for each 2 week break-if you want to use it.
You are paid a monthly salary which takes into account the time you have off-the salary is the same every month-if you take leave or not. This applies to all the different contracts available ie: 6/2 or 5/3 or 4/4.
Good luck & any information you want about VAC or life in Vietnam is contained in this thread.
