I came across this deal on the Secret Flying account on Instagram.
This is an excellent deal and super cheap for a business class with Qatar Airways.
The flights I found are available from May to December 2016 for £580 which is excellent via Kayak.co.uk
If you are looking for cheap flights to travel to Asia then these prices cannot be beaten for business class comfort.
You can use your Avios or book a cheap flight with Ryanair to get to Oslo from the UK. You can either fly directly from there or even stay a day and explore Oslo before heading to Thailand. From Thailand you can definitely explore some of the neighbouring countries with low cost airlines such as Air Asia and JetStar.
