Book Cheap Flights in April 2026

Use our calendar to find the cheapest flight

The best place to start when you're looking for cheap flights in April with Alternative Airlines is our handy Best Fare Finder calendar. Our flight search calendar highlights all the cheapest flights in green and all the most expensive flights in red. It's really easy to use and useful as it eliminates the most expensive times to fly before you've even run a search.

To use the calendar, just click to select a date as you normally would on our flight search form. The calendar will automatically load with dates colour-coded.

Sort by 'lowest price'

Once you've run a flight search on our site, we will list all available flights for your chosen dates and destinations.

By default, we sort these results by 'Recommended', however, if you care more about finding the cheapest flight than you do the shortest journey time, you can change the results to sort them by 'Lowest Price'.

This will bring all the cheapest results for your chosen dates in April to the top of the results so that you don't have to search through hundreds of flights yourself.

Pick a payment method that'll help you save

While it won't technically make your flight any cheaper, if you choose the right payment method, it can make your flight easier to pay off and budget for, which can help you in the long run.

For example, our Buy Now Pay Later and financing payment options allow you to spread the cost of your flight over time. This means that you won't have to pay the total cost of your flight upfront and can pay it back in easy-to-manage instalments.

We have various different Buy Now Pay Later options, such as Afterpay, Klarna, Affirm and more! You can find them all at the payment stage of the booking process.
