How to find cheap flights in September?

  • Be adventurous. Look for a deal rather than a destination.
  • Be a travel hacker. Travel during “unpopular” times – early morning, late evening.
  • Be an explorer. Consider departing outside of your regular airport.
  • Be a bargain hunter. Look at long layovers as a bonus destination.
  • Be a fool for tools. Use Skyscanner’s Everywhere Search & sign-up for Price Alerts.

  2. Type in your origin and destination locations
  3. View September price options in Calendar (color-coded dots) or Chart (bars of varying heights). Then just select your dates to view flight options based on the cheapest days to fly.

Top destinations to visit in September

San Juan, Puerto Rico – There are three bioluminescent bays in Puerto Rico, but the brightest is off the coast of Vieques Island. It is known fondly by tourists as Mosquito Bay. The bioluminescence is caused by microorganisms that glow in a blue-green color when disturbed. These microorganisms are present in a high enough concentration in this bay to create a visible glow for visitors, which is a rare sight.

Bangor, Maine – To truly see the Milky Way, you need to escape the light pollution of cities and towns. The Acadia Night Sky Festival offers just the opportunity. This festival celebrates “the starlit skies of Downeast Maine” and draws amateur and professional astronomers to attend workshops, speaking sessions and hands-on experiences during the day, and to stargaze at night.

Denver, Colorado – Fly into Denver, but then head southwest to Breckenridge for the annual Breckenridge Wine Classic or Breckenridge Oktoberfest (if you stay long enough, you can attend both!). The weather is beautiful this time of year, making these outdoor experiences even more enjoyable.

Skyscanner Price Alerts

Travel research and data can point to the cheapest days to fly and help you identify when plane tickets will be available at the lowest prices. The easiest way to monitor changes in prices is by setting up a free Skyscanner Price Alert.

When you have entered the detail of routes you are interested in then you will be immediately sent an email to let you know when the price changes on your chosen flight. Skyscanner constantly monitors price changes to give you the most up-to-date information. When you find the best time to book a flight, let Skyscanner help you start your next travel journey.
