How do you get the best deal on a flight from BOS to SEA?

We've been in the game a long time, so we know a few ways to get the best price on your flight to Seattle. You can pocket that extra cash for more than just getting from point A to point B with a little know-how.

Which days of the week are cheapest to fly?

It pays to be a weekday warrior. Those middle children of the work week, Tuesday and Wednesday, typically have the best rates. Next in line are Thursday and, surprisingly, Saturday. Most people like to come back from their trip on Sunday so you can save by leaving a day earlier.

Why are flights cheaper if you stay over the weekend?

If you stay through the weekend, generally that return ticket to BOS can be cheaper since you'll be leaving earlier in the week. All those business travelers have less elastic schedules, so that means more savings for you. Good thing to tell your boss if you have a business trip -- wink-wink.

Can you save while traveling during the off-peak season?

There's good reason that many people travel during certain times of the year -- they want to enjoy incredible weather. Summertime is when Europe, Hawaii, and Alaska are at their most popular. Florida, New Orleans, and Southern California are the most popular in springtime. Winter is prime for Mexico and the Caribbean because of its warm weather, as well as ski and snowboard destinations like the Colorado Rockies. Who doesn't love some good fall foliage? The Pacific Northwest, Northern California, and New England are popular this time of the year. If you can plan your trip around these peak seasons, you'll not only save money, but you'll typically avoid the crowds. Win-win in our books.
