Hi mate. That sounds like a decent deal for November, and booking the Phuket leg in advance is possibly a smart move just now.
I do recall another BM getting stuck in Bangkok for a lack of Phuket flights. All the other usual suspects, KLM/Air France, BA/Qantas, Emirates are around 510-540 wherever you look at the minute.
I have some air miles and got a flight with Qatar airlines for 209.00 in September, it's the school holidays that seem to make the biggest difference, so avoid them.
My understanding of courier flights is that a company needs to send some freight in a rush, they need the luggage allowance and you get the seat. A cheap way of getting there but with only carry-on bags.
