I saw these new airlines while browsing and thought I would pass them on. They seem fantastic value.
First up is Oasis which flies from Gatwick (London) to Hong Kong for £99 each way (which after taxes etc works out to around £300 return.
The other airline is Nokair
This flies from Hanoi to Bangkok. I looked today and the prices were $8.97 from Hanoi to BKK and $0.09 from BKK to Hanoi! After tax this worked out less than $100 return.
Take a look. Let me know if you see any other cheap airlines that you think might be useful or especially if you find a cheap way from Hanoi/HCM (I'm moving to Ho Chi Minh early December) to Hong Kong.
