For London you are better off using STA's deal. All flights will stopover in Bangkok. The OP on AFF reckons India is a good deal too but don't know much about that.
Pick flights from now until 30 November 2016.
Thai Airways website is very difficult to find the cheap fares. You must enter the dates on the specials page where a new window will open up. Always find the fares from the specials page otherwise you might be presented with a different price (according to AFF). Skyscanner seems to be picking them up but again you'll need to go through manually as the calendars don't seem to be populated.
There are no additional fees or charges by booking through BestJet.
Via AFF
