How to book the cheapest flight to Boulder?
Picking up cheap flights to Boulder is as simple as booking your ticket with Orbitz. But if you’re eager to make sure you’re nabbing the best flight deals around, here are a few tips worth following:

  • Depending on where you’re taking off from, select the ‘Nearby airports’ function (located under the departure and arrival options). In some instances, alternative departure points will offer better prices on fares.
  • If your plans aren’t cast in stone, click on the ‘Show flexible dates’ link to see the flight deals for different departure dates. You may find a cheaper fare.
  • Select ‘Show options’ to filter your search results. You can choose your preferred airline and seating class here. Under ‘Sort & Filter’ to the left, you can even specify whether you’d like to fly in the morning, afternoon or evening.
  • The early bird gets the most impressive deals, so book as soon as you’ve worked out your travel dates. The most affordable airfares are quick to sell out and prices increase as the departure date nears.
  • Consider combining your hotels, flights and car rentals into a package deal to make your dollar go further.
  • Don’t fly during the busy season if possible. By avoiding school vacations and summer, you can save plenty on your airfares.

Generally speaking, January is the cheapest time to purchase your airfare. This is followed by February and August. Keep this in mind while tracking down a cheap flight to Boulder.
What day of the week is the cheapest to book a flight to Boulder?
Land a fantastic flight deal by booking on a Tuesday, Wednesday or Saturday. These are typically the best days of the week to score cheap fares to Boulder.
What is the cheapest day of the week to fly to Boulder?
If you’re chasing cheap flights to Boulder, leave at the start of the week. Orbitz data from 2020 shows Monday is the cheapest day to jet off, followed by Tuesday. Saturday has the most expensive fares, so avoid flying on this day and do your wallet a favor.

What do I need for the flight to Boulder?
Nothing’s more enjoyable than jetting off on an adventure, but it’s smart to be prepared. These practical tips will help get your journey started on the right foot:

  • Whether you print it out or use an electronic one, you’ll need your boarding pass to walk on to the plane. You’ll also need some form of government-issued ID. If you’re flying internationally, make sure your passport is valid.
  • Make time fly by even faster on your short flight by packing the right things. Think tasty snacks, a water bottle and entertainment. If you’d like your journey to Boulder to go nice and quietly, squeeze some headphones in your bag too.
  • Whatever the weather’s doing outside, plane cabins can get chilly. Bring a sweater on board to keep yourself nice and toasty.

If you think a first or business-class fare is out of your reach, you may want to think again. Here are some top tips to help you score a premium flight to Boulder for a whole lot less:

  • Flexibility is everything. By being open to other travel dates, you’ll have more chances of picking up a great deal on business or first-class airfares.
  • Low-cost airlines offer first or business-class seats at a fraction of the usual cost. Ditch the full-service carriers and book with one of these cheaper options.
  • Take advantage of your airline’s loyalty scheme and use points to upgrade your seat. You can also bid for an upgrade in an online auction.

Anytime is a fantastic time to experience Boulder, but February, March and June are the busiest months. For most places in the Northern Hemisphere, the summer commences June 20. If you’d sooner spend most of your days in a T-shirt than a winter jacket, this time of year may be perfect for you. Expect average daily highs of 75 ºF and nighttime lows around 55 ºF.
