Boston (BOS) to St. Louis (STL)

Are you flying to St. Louis for a much-needed vacation or is it about time for you to have a family reunion? Or maybe you're traveling for work? Hey, anything that gets you away from that desk is a win in our books. You're in the right spot to get a killer deal on your upcoming flight from Boston. Whether you are an airline aficionado or only have a few trips under your wing, read on to see how to book a too-good-to-be-true flight.

How can you get a great rate on tickets from BOS to STL?

We've been doing this for a long time, so we know a couple ways to snag the best rate on your flight to St. Louis. You'll make spending less look so very good with a little know-how.

What is the cheapest day to fly?

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 vacay by a day and increase your savings.
  • Monday through Thursday—If you're flying internationally, deals are often available when departing these days.

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 itineraries, so that means more savings for you. Of course, we don't want to twist your rubber arm or anything.

What are shoulder seasons?

Shoulder or off-peak seasons are when most vacationers aren't traveling to certain locations. So when it's cold, most people head off to warmer places like the Caribbean, Mexico, Hawaii, etc., just like the birds (they had it figured out). But in the summer, you'll find that Europe gets busy. You can usually save on your ticket when you fly when everyone else isn't.

Is that the lowest price?

Unsurprisingly, you're not the only vacation-hungry person waiting a good price on a ticket from Boston to St. Louis. You might miss out on your chance to dial in the time and the flight you wanted.

How else can I save on my flight from Boston to St. Louis?

We think the Hotwire Hot Rate is one of the best deals out there, although we may be slightly biased. It's one of our ways to help get you a great deal on your flight from Boston (BOS) to St. Louis (STL). After your purchase, you'll get the time and name of the airline, but it is a risk where you can reap the rewards.
