Revealed: the best day to book flights

Associated Press put out a short report saying that, although travellers dream of the perfect trick to find the cheapest airfare every time, every trip, there is no easy formula for best time to book airline tickets.
There are theories, some of them backed up by real number-crunching, like shop on a Tuesday, 57 days before your flight. But using a tidy formula to find the cheapest fare may be as futile as trying to time the stock market, the report says.
Airlines Reporting Corp, which handles tickets sold through travel agents, pinpointed Day 57 as when you?ll find the cheapest average domestic fares. But in a nod to the inexactness of the science, it also said that the lowest domestic prices are relatively unchanged about 50 to 100 days before a flight.
