How can you get a great rate on tickets from SEA to LON?

We've been doing this for years, so we know a couple ways to find the best price on your flight to London. You can pocket that extra cash for more than just getting from point A to point B with a little know-how.

What is the best day of the week to book a flight?

With the right attitude and flexibility, you can fly for less. Below are the cheapest days to fly:

  • Tuesday and Wednesday—You know how most stores are not crowded midweek? Same thing here. So, get on while the getting is good.
  • Thursday and Saturday—Get a head start on that Friday crowd. This also works on your return flight. Shorten your vacay by a day and increase your savings.
  • Monday through Thursday—If you're flying internationally, deals are often available when departing these days.

Can staying the weekend get me a cheaper ticket?

If you stay through the weekend, generally that return ticket to SEA can be cheaper since you'll be leaving earlier in the week. All those business travelers have less flexible itineraries, so that means more savings for you. We are all for that!

Why travel during the off-peak season?

It's all about going to a place when its weather is at its best. Summertime is when Europe, Hawaii, and Alaska are at their most popular. During spring, New Orleans, Florida, and California open their arms to tourists. Winter is prime for Mexico and the Caribbean because of its warm weather, as well as ski and snowboard destinations like the Colorado Rockies. During fall, Northern California, the Pacific Northwest, and New England draw visitors. Flying during less popular periods can mean extra money in your wallet -- yes, please!
