How to Book Cheap British Airways Flights

Book Now, Pay Later & Finance

Our ‘book now, pay later’ payment options may not make the total cost ‘cheaper’...but they can make booking your airfare much more affordable by splitting the cost over time. Instead of paying the full amount today, you can break up the cost into more manageable chunks, paid over a fixed number of weekly monthly insalments. Many of our shorter-term payment plan options are completely interest-free — you only pay the total cost of your flights, without any extra costs or hidden fees.

Our buy now, pay later and finance payment plan options include Afterpay, Affirm, Klarna and Zip, among others. Whether you book flights with British Airways, or any of the other 600 airlines that we ticket, you can spread the cost over time when you book through Alternative Airlines.

Choose the Cheapest Time to Fly

The day and time that you fly will often be just as important as any other factor when you’re looking for cheaper flights. Here are some top tips to help you find the cheapest time to book your flights:

1. Fly during the shoulder season

Rather than flying during peak periods, fly during the shoulder season. You may find that by flying to Europe in September, rather than in July or August, you’ll see a reduction in the cost of your flights.

2. Don’t fly during public holidays.

For the cheapest flights, avoid travelling during public bank holidays such as Christmas.

3. Catch a red eye flight

Fly at night, or look out for flights that depart really early in the morning or late at night.

4. Use our Best Fare Finder tool

This is a great way to find the cheapest time to fly. We use a traffic light system, so when you select your departure and arrival dates you can see what days offer the cheapest flights. If you can be flexible with your dates of travel, consider selecting a ‘green’ date to benefit from the cheapest prices.
