Qatar Airways is really pushing it with their current sales in Business Class – you can now book return fares to Bangkok from Oslo for just $1,119 RT.
There aren’t a lot of dates but the Qatar Airways website has a handy 15 day search tool. Look for the Business Promo for NOK ~5,000 fares.
The fare bucket is I and should earn 100% or more with most Onewarld programs.
