An economist created a formula to buy cheap airfare

An economist created a formula to buy cheap airfare. Makoto Watanabe is the author of a study (to be published in the journal Economic Journal) on how to purchase airline tickets cheaper.

Although we know that buying in advance can reduce costs (but runs the risk of a change of plans), it sometimes happens that a flight out overnight, so the prices are far above the ordinary .

However, beyond the exceptions, there is a way to purchase airline tickets more accessible.

To do this, the economist Makoto Watanabe created the mathematical formula:? A = GUG + min (k - g, (1 - g) (1 - r)). What does it mean? That the right time to buy tickets is eight weeks earlier.

It also makes mention of other factors to get cheap airfares, as taking into account the time of day you make the purchase. Watanabe recommended the purchase of tickets for the afternoon and on Wednesdays.

Anyway, sometimes, some journeys can not be made so early. But to the extent that you can choose to be taken into consideration these tips.
