Hi guys,
I'm based in SGN with Jetstar 737 and I can tell you that VN needs huge amount of pilots. First because some are leaving and second because you can see several aircraft grounded because they don't have crews to operate them.
I recommend coming to SGN, things are really cheap... specially if you know where to search and you don't need to live in your 300 m2 house with swimingpool and tennis court.
Here in Jetstar they are also looking for pilots and with the introduction of the first A320 in one month it seems that they will have to pay the same as VN Airlines pays to CPT and FOs. I believe they're still looking for DEC for the 737, don't know about the req.
