Call out to experienced flight searchers/geeks/experts.....making last-minute travel plans LON-SFO-SYD-MEL. Want to leave next Mon 30/1, and watching prices go up and down last few days with the usual suspects - Kayak, Momondo, Skyscanner, Matrix... They are similar to each some days, then other days vary so much! All of them up and down.
Any advice if prices will ALWAYS go up, or if they might go down as well in the days before? Is waiting and holding my nerve a COMPLETELY bad idea? Any tips appreciated.
