when is best time to buy airline tickets
In general, airlines offer their cheapest flights during business hours, when value-minded business travelers are booking flights. The best single time and day to book a flight is 3 p.m. Eastern time on Tuesday, according to Rick Seaney, CEO of FareCompare. Early morning or late-night flights are less popular, and therefore cheaper. Purchasing a so-called red-eye flight may also save you money.
But a study by Expedia and the Airlines Reporting Corporation says that based on billions (yes, billions) of passenger flights from January 1, 2016, through October 24, 2016, the best day to buy airline tickets is Sunday, especially if you're booking more than 21 days in advance.
