Tokyo on Avios via Finnair / Qatar / JAL
I would like to visit Tokyo this year and as is well known it is one of the hardest routes to score reward flights on. I have a fair amount of Avios though so could use one of Finnair / Qatar / JAL but I'm really struggling with availability. Are there any platforms that will allow me to see availability though the year much like SeatSpy for BA?
TIA all and apologies if this has been asked before.
