Major,
The letters going the rounds are showing positions on the 747 or A330 only. These are the fleets with the most training sectors.
You will not start in HKG, it will be in Adelaide to do your licence conversion. You can only start after you have given proof you have resigned from your previous position. You will get paid around $100 a week in Adelaide with food and board provided.
You will sign a bond for your training at around HK$500,000, that bond disappears after 6 years.
After finishing Adelaide people are being delayed starting in HKG doing their simulator training, I have heard in excess of 6 months for some people on the 747 this year.
You have the information.
