Friday flights now cheapest as traditional travel booking wisdom dies according to new data

The days of booking your flights six months in advance to save a buck are officially over.

As domestic airfares tick up 3% this year, a massive shift in travel data reveals that Friday has dethroned the weekend as the cheapest day to both book and fly — saving savvy travelers hundreds on everything from quick trips to Las Vegas to international treks to Tokyo.
