I'm not sure what's happened but all of a sudden instead of getting £100 off with 15k Avios it's now £200. Whether it's permanent or not I don't know or maybe even a mistake. They have 31 Dec return flight for £269 and 9 March for £360. 31 Dec is out LHR, back LGW. Can't remember what March airports were but they have a mixture of both. Very cheap. Never seem prices this low but great deals for sure. Update It's a Black Friday deal, must book by 30 November 2015 for travel before October 2016.
