How do you get the best deal on a ticket from St. Louis to Silicon Valley?

Hotwire has been doing this for years, which means getting that great deal on a Silicon Valley flight is easy-peasy. You'll make spending less look so very good with a few simple steps.

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. Most people opt to depart at the beginning or end of the week.
  • Thursday and Saturday—Get a head start on that Friday crowd. This also works on your return flight. Shorten your holiday by a day and increase your savings.
  • Monday through Thursday—If you're flying internationally, deals are often available when departing these days.

What's the Saturday night stay rule?

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

What are shoulder seasons?

Off-peak and shoulder seasons are when most vacationers aren't going to certain locations. So when it is cold, most people head off to warmer climates like the Caribbean, Mexico, Hawaii, etc., just like our feathered friends. But in the summer months, you'll find that Europe gets busy. If you want lower airfare and avoid the crowds, travel when everyone else isn't.

Is that the lowest price?

Airline carriers change their rates often. If a price you love pops up, then grab it! You're not the only vacation-hungry person seeking an awesome deal on a flight from St. Louis to Silicon Valley. You may miss your chance to dial in the time and the flight you wanted.
