When Should I Book Flights for my DIY Trip?
We’ve all been there – watching flight prices yo-yo up and down, wondering if today’s the day to book. Experiencing what I call “booking paralysis” – when you’re terrified of buying plane tickets in case the price plummets a week later. Or you jump in too quickly, worried they’ll double overnight.
In this guide, you’ll learn the best time to book flights for DIY trips and tricks to get the best deals – so you can book with confidence. I’ve pulled together insights from expert studies, personal experience, and practical tips to help you time your booking just right.
Why Flight Price Fluctuate So Much
Flight prices fluctuate massively. People sitting next to each other on the same flight could easily have paid a difference of hundreds. It’s all based on supply and demand – and some very complex algorithms.
Fares rise as seats fill up or travel dates approach, so timing is everything. You want to book when demand is low – that might mean snapping up a seat on a popular route early, or travelling off-season when fewer people are flying.
Airlines use dynamic pricing, adjusting fares based on route, popularity, season, competitor activity, booking patterns and how many seats remain unsold.
The earlier you start watching and planning, the better your chance of spotting a deal.
Check Out the Flight Price History and Trends
Before you do anything else, check the flight price history for your specific route on a site like Skyscanner or Google Flights. This gives you a clear picture of what’s normal and what’s a bargain.
Once you’ve done this, you’ll know which months tend to be cheaper and whether you’re getting a deal or paying over the odds.
How Far in Advance Should You Book Your Flights?
Booking Early for Peak Season Travel
From both research and experience, booking flights as soon as they’re released can secure the cheapest fares for peak travel times – summer holidays, Christmas, and school breaks.
We always book our February half-term ski flights as soon as they’re released. We know the prices won’t drop because demand is so high.
Be cautious though – sometimes social media can unexpectedly drive demand sky-high. We saw this happen with December Lapland flights. If the price seems ridiculous, don’t rush to book!
Airlines release flights around 11-12 months in advance, and for peak-season travel, these early fares are often the best value. Many regular travellers notice that once those early seats start selling, prices rise fast.
If you know your travel dates – especially for July, August or December trips – booking as soon as flights are released can lock in the best deal.
For Short-Haul Flights
For short-haul routes (especially within Europe), budget airlines like Ryanair, easyJet and Wizz Air tend to compete heavily on price. Fares often start low, climb steadily, and sometimes drop again during flash sales.
The sweet spot is usually around 6-10 weeks before travel, but for school holidays or popular destinations, early birds often get the best prices.
✨ Tip: Set a price alert around 12 weeks before you plan to travel so you can jump when fares drop.
For Long-Haul Flights
For long-haul routes, early planning usually pays off. Many travel studies suggest booking 6-8 months ahead for the lowest fares – especially for high-demand periods like summer or Christmas.
Long-haul airlines often release promotional fares several months in advance.
✨ Tip: Keep an eye out for the British Airways and Virgin Atlantic sales, usually in January and late August – they often trigger competitive prices across other airlines too.
Cheapest Months and Days to Fly
According to travel industry trends, January and November are often the cheapest months to travel, as demand dips just before and after the festive season.
Midweek flights are typically the quietest (and cheapest), while Fridays can offer savings compared to Sundays – the priciest day to fly since most people want to be home before the workweek.
If you’re flexible, use tools like Skyscanner’s “Cheapest Month” feature or Google Flights’ price tracker to find the best-value dates for your chosen route.
Booking Flights Around the School Holidays
Hunting for affordable flights over Easter, summer, or Christmas? The key is to plan early.
We try to book as soon as flights are released, but airlines like easyJet are now publishing schedules further in advance than ever – sometimes before you’ve even thought about your next trip!
Cheap seats for these peak holiday periods often appear between November and February, though prices can still fluctuate. If a route isn’t selling well, airlines sometimes launch flash sales to boost bookings.
Track your preferred routes and jump when you see a price dip. Setting up Google Flight alerts or subscribing to airline newsletters means you’ll catch those deals before they disappear.
When Last-Minute Works and When it Doesn’t
Last-minute flights can sometimes be cheaper, but usually only when airlines need to fill unsold seats. For popular routes, the opposite is true – prices go up the closer you get.
One charter airline that often bucks this trend is TUI. They sometimes offer deep discounts within a few weeks of departure, mainly to sunny European, Florida or Caribbean destinations.
Waiting for last-minute bargains takes nerves of steel – which we admittedly lack! But if we were braver, we could have saved hundreds on our flights to Florida last July.
Best Strategies for Finding Cheap Flights
- Use Price Trackers: Set up fare alerts on Google Flights or Skyscanner.
- Sign Up for Airline Newsletters: Airlines announce sales to subscribers first.
- Join Cheap Flight Alerts: Subscribe to Jack’s Flight Club or Secret Flying (on FaceBook) for handpicked deals.
- Travel on the Holiday Itself: Flying on Christmas Day or New Year’s Day can be surprisingly affordable.
- Avoid Peak Weekends: Returning on a Monday instead of Sunday can make a big difference.
- Book Early for Popular Routes: The most in-demand destinations sell out fast, so don’t wait too long.
Best Time to Book Flights to Popular Destinations
For popular destinations, it’s best to avoid the peak season if possible. Travelling just before or after can save you a small fortune.
Long-haul flight deals often appear one to two seasons before travel (for example, summer deals surface in winter).
Set up price alerts for exotic routes – flash deals to places like the Maldives or the Caribbean are rare, but they do happen and are worth snapping up quickly.
Common Myths About Booking Flights
- Flights are always cheapest on a Tuesday.” Not always true – though midweek often still costs less. Use monthly search tools on Skyscanner or Google Flights for a full picture.
- “Last-minute is best.” Only occasionally, and mainly if you’re very flexible.
- “Clearing cookies lowers fares.” Largely a myth. Instead, search on comparison tools or use a VPN for peace of mind.
Final Tips for DIY Travellers
Airfare pricing can feel like a guessing game, but understanding how airlines set their prices puts you back in control.
For most DIY travellers, the golden rules are:
- Research price trends on Skyscanner or Google Flights.
- Book early for peak season, especially when flights first go on sale.
- Wait a few months for short-haul budget routes outside major holidays.
- Stay flexible and keep an eye on trackers for sudden drops.
- Sort your car hire alongside your flights: if you’re picking up a rental at your destination, it’s worth running a quick search on Discover Cars at the same time as booking flights, since it compares quotes from dozens of local and international rental companies in one place rather than making you check each one separately. Most bookings come with free cancellation too, so you can lock in a good rate early and still adjust your plans later without losing money.
Knowing when is the best time to book flights is not about luck – it’s about strategy. And with a little forward planning, you’ll be the one bragging about how cheap your flights were at the airport bar.
