First, the day you book: In a previous study Hopper found that the cheapest day to book your flight is Thursday for both domestic and international flights. However, there's a big caveat: The savings are smaller than you may think: about $10 for typical domestic routes and about $25 for international markets.
Why these days are cheapest: Most of us don't want to fly on Tuesdays, Wednesday or Saturdays, so airlines discount prices hoping the cheaper fares will get you to take that trip you were on the fence about, in order to fill up their (increasingly rare) empty middle seats.
