Cheapest Day to Fly – Wednesday
We did an in-depth study of our proprietary historical airfare database (world’s largest) and pinpointed the cheapest day to fly is Wednesday for domestic travel (gory details at the link).
Wednesday is one of the three cheapest days, the others are Tuesday and Saturday (Friday and Sunday the most expensive days to travel). The cheapest day to travel internationally are a bit different — we are working on this research and it should be up shortly.
The cheapest time to fly is typically the first flight out in the morning – yes, that means you have to get up at 4am. Next best times are flights during/after lunch and flights at the dinner hour (of course the absolute cheapest time to fly is on those limited routes with red eyes).
