What is the cheapest day to fly?

Going with the flow can pay dividends when it comes to getting an affordable flight. Our dear friends, Tuesday and Wednesday, typically have the best rates. Next, Thursday and, surprisingly, Saturday. Most like to fly back from their trip on Sunday so you can save by leaving a day earlier.

Why travel during the off-peak season?

Shoulder or off-peak seasons are when most people aren't flying to certain locations. So when it is cold, most people head to warmer places like the Caribbean, Mexico, Hawaii, etc., just like the birds (they had it figured out). But during the summer months, you'll find that Europe is really popular. You may not get the ideal weather, but you'll generally get better prices and avoid the crowds.

Is that the lowest price?

Airlines change their rates seemingly by the minute. If you find the price you like, then get it. There are a lot of other people that are longing for an awesome bargain on a ticket from Boston to San Francisco. You could miss your opportunity to get the flight and the times you need.
