What is a cheap flight calendar?

A cheap flight calendar is a popular way to compare airfares across multiple days. Many airlines use fare calendars to help customers spot the cheapest travel dates quickly and easily. It’s particularly useful if you have flexible plans and want to avoid overpaying for a seat.

At Alternative Airlines, we’ve got the Best Fare Finder tool. You’ll see a colour-coded calendar that displays the lowest fares available across several days. The green bars indicate what we call “Great days to fly” - days where flight prices are notably lower than average.

It’s ideal if you're a bargain hunter, flexible traveller or if you want to stretch your budget further. The Best Fare Finder combines real-time pricing from 600+ global airlines with flexible payment options, so you can book smart and pay in a way that suits you.

Tips for booking cheaper flights

Finding cheap flights is part planning, part timing and part flexibility. Here are some tried and tested tips that can help you save:

  • Travel midweek - Tuesdays and Wednesdays often come with lower prices, as fewer people fly on these days.
  • Book early - The earlier you book, the more chance you have of grabbing a lower fare, especially during peak travel periods like holidays or school breaks.
  • Use our cheap flight calendar - A day or two can make a big difference. Let the cheap flight calendar guide your choice.
  • Consider nearby airports - Flying into or out of smaller or alternative airports can unlock significant savings.
  • Sort our results by "cheapest" - After you've made a flight search, you can sort the results to show the cheapest fares available for your chosen route.

A little flexibility can go a long way. The more open you are to adjusting your travel plans, the more likely you are to find a great deal on your flights!
