this is a bit of a funny time to be looking for flights we r currently in what we call in the industry "no mans land!!!" the current early birds that were out finished on the 23rd dec and the next round of early birds hasn't been launched yet so current pricing is basically at a full fare with no specials. usually airlines will come out with the next round of Earlybird specials in jan that will finish at the end of feb so while they will not be as cheap as if u booked back in sep/ Oct they should be cheaper than u r currently finding. that said there are no guarantees with airlines we r just working on the patterns from the last few years.
I would wait 7/10 days and try again. if they drop then u shud def book sooner rather than later as it will only go up as availability goes down
pm me if u need help
