I got onto Avios.com chatline to figure out what's happening with DUB-LON reward availability and they told me that for Nov/Dec they only have 5 of the 12/13 flights available for reward booking and that they are all sold out - not one seat on any day (and they told me there are 8 reward seats on all these 5 flights) - considering how Nov is a "quieter" travel month, it seems incredibly unlikely that not one seat i s available. They then proceeded to tell me that on 1 Jan - there is loads of availability.!! Either they have pulled availability completely or there is an issue in the system ... IMHO
