When should I buy an airline ticket?

In order to get the best price

on an airline ticket, it helps to know when to buy. Airline ticket prices are constantly changing. A general rule of thumb is to buy tickets at least 3 weeks before the flight. The most expensive time to buy would be the day of the flight, which is when business travelers often book. International flights usually should be booked as soon as possible, well in advance. Prices for flights within the US are usually best about 21 to 42 days before the flight, or about 3 to 6 weeks in advance. Prices just aren't as good outside of that time period. Discounts also often come into effect on Monday nights, so a good time to check prices would be late Monday night, or early Tuesday morning. Thursdays are the days to avoid purchasing a ticket. These are the days when markups happen, and many airlines routinely add $10 to the ticket prices. Finally, flights that take place during the week tend to cost a little less on average than weekend flights.

Happy travels!
