Summer Holiday Flight Deals from the UK: When and How to Book

Why summer flights cost so much

The reason is simple: millions of families want to travel during the same few weeks, because that is when schools are closed. English schools usually break up in the third or fourth week of July and return in early September, and airlines and tour operators raise prices to match demand.

Flights that cost £60 a head in June can cost £250 in the first week of August. That is not a scam, it is supply and demand, and it means that even small changes in your dates can make a big difference. The cheapest approach is to avoid the peak weeks altogether, or to be well prepared if you cannot.

Checking the total, not the headline

A family of four can be caught out by add-ons that nobody mentions in the headline price: a hold bag each way, seat reservations so that children sit with parents, priority boarding and airport parking. On a low-cost fare, these can double the cost.

Before you commit, work out the full price for your group, including transfers and a meal on the flight if you want one. A fare that includes more can be cheaper than one that looks lower on the first page of results.

The calendar: English and Scottish school holidays

Most English schools break up around 22 to 24 July and return in early September, with local variations. Scottish schools break up in late June and return in mid-August, so fares from Scottish airports peak earlier. Welsh and Northern Irish schools follow their own dates.

Check your local council's term dates, and compare with the school holidays of the other nations. If you have no children, you have a big advantage, because the weeks before and after school holidays are significantly cheaper.

Dates that save the most

Late May half-term to early July is usually the best value, with warm weather in most of southern Europe. The first two weeks of September are another sweet spot, with the sea still warm and prices dropping sharply.

Within the school holidays, flights on Tuesday, Wednesday and Saturday are cheaper, and the first and last weeks cost less than the middle. Flying on a Saturday morning rather than a Friday can save hundreds of pounds for a family of four.

What the same week costs in July, August and September

As an illustration, a family of four flying from Manchester to the Spanish Costas might pay £450 in late June, £1,300 in the first week of August and £600 in mid-September. Hotels follow a similar pattern, so the gap across the whole holiday is bigger than the flights alone suggest.

These are only examples, but they show why moving two weeks can be worth more than any booking trick. If you can use the shoulder weeks, a better hotel and a longer stay may cost less than a short peak-week trip.

The cost of taking children out of school

Taking children out of school in term time can lead to a fine, and rules differ across the UK. In England, fines for unauthorised absence are set nationally, currently £80 per child per parent if paid quickly, rising to £160 if paid late, and repeated absences can lead to further action.

Some families decide the saving is worth the fine, but others find it is not, once you count the penalty and the risk. Check the rules with your school and council, and consider whether a flight in the first week of September is a better compromise.

When to book

The best fares for summer are often released in the autumn, and the cheapest ones go first. Booking nine to twelve months ahead gives the best choice, and booking four to six months ahead is still reasonable. Last-minute deals in August are rare and risky.

Set a price alert as soon as you know the dates. Our guides to tracking fare drops and the best time to book flights in 2026 explain how, and how far in advance to book international flights gives the wider picture.

Booking with a family: a sensible order

Start with the dates, because they limit everything else. Then pick two or three destinations, check the flights from your two nearest airports, and look at hotels. Only then compare packages and flight-only prices.

Book the flights and the first night's hotel on the same day, so the key parts of the trip are fixed together. Leave small things, such as excursions, until you arrive, since they are cheaper and more flexible once you are there.

The airlines and operators

Jet2, easyJet, Ryanair, TUI, British Airways and Wizz Air all fly summer routes, and Jet2holidays and TUI also sell package holidays. Jet2 and TUI include a bag in their fares, while low-cost airlines charge extra.

Compare packages with flights only, since in peak weeks a package can be good value. Check what is included, such as a hold bag, transfers and a meal, and look for ATOL protection. Our guide to basic and standard fares explains the main differences.

Popular destinations and what they cost

Spain, including Alicante, Malaga, Palma and the Costas, remains the most popular, with Portugal's Algarve, Greece's Crete, Rhodes and Corfu, Turkey's Dalaman and Antalya, Italy and Croatia not far behind. Prices vary a lot between them in August.

Greece and Croatia are among the most expensive in peak weeks, while Turkey and Spain's less fashionable areas can be cheaper. If you are flexible, look at what is cheapest and build the holiday around that.

Regional airports versus London

Many families outside the south-east can fly from their nearest airport, which saves driving or trains and parking costs. Manchester, Birmingham, Bristol, East Midlands, Leeds Bradford, Newcastle, Edinburgh and Glasgow all have strong summer programmes.

Compare prices from several airports, and count the extra cost of getting there. A two-hour drive to a cheaper airport may not save money after fuel, parking and tolls.

Beaches, sea temperature and the best weeks

In southern Spain and the Balearics, the sea warms to around 22 to 24 degrees by late June and peaks in August and September. Greece and Turkey are similar, and the Algarve's Atlantic water is cooler. September is often the warmest sea of the year for swimming.

That is why the early autumn weeks are so popular with those who have no school constraints. Beaches are less crowded, restaurants have tables and the heat is more bearable than in August.

Flight-only or package?

For a family, a package may include a bag for each person, transfers and a meal, and can be cheaper than adding those to a flight-only fare. It also gives ATOL protection, which refunds you if the operator fails.

Flight-only gives more freedom, and it can be cheaper outside peak weeks. Compare both for the same dates, and read what is included. Our vacation packages service and family vacations service can compare options.

Heat, wildfires and extreme weather

Southern Europe now regularly sees heatwaves in July and August, with temperatures above 40 degrees in Spain, Italy and Greece, and wildfires have affected islands including Rhodes and Corfu. If you have young children or health conditions, think about when and where you go.

Choose accommodation with air conditioning, plan activities for mornings and evenings and keep up to date with local advice. You can read what you are entitled to in our guide to delay and cancellation rights.

Queues, EES and ETIAS this summer

Summer is the busiest time at European borders, and the EU's new Entry/Exit System has added fingerprint and photo checks that can slow queues, particularly at the start of a holiday. Allow extra time at departure and arrival.

Your passport must be valid for at least three months after your return date and less than ten years old. ETIAS is planned and its start date has changed, so check the official information.

Travelling with children on a long summer flight

Short flights suit families, and anything under four hours is manageable. Book seats together, since airlines charge for seat selection, and pack snacks, entertainment and a change of clothes in the cabin bag.

Check the airline's rules on pushchairs and car seats, and the rules for liquids. Early morning flights can be cheaper, but they are hard on tired children, so consider a mid-morning departure.

Airports in summer

UK airports are busiest in the first weekend of the school holidays, and security queues can be long. Arrive at least three hours before your flight, book parking in advance and use fast track if the queue is long.

Check the airline's advice on arrival times, and have your boarding pass ready. If you have a very early flight, consider an airport hotel the night before, which can be good value with parking included.

Parents, teachers and flexible workers

Families with children in school have little choice about dates, but others do. If you are a teacher, a school worker or a parent of pre-school children, you have more flexibility than you think, and a week in June or September can transform the budget.

If you work in a job that allows remote work, consider a longer trip in the shoulder season. Many people are able to take a week in September and work from the destination for a few days, which spreads the cost of flights.

Cheap summer routes from the regions

Some of the cheapest summer flights are to Spain's Costas, Majorca and Ibiza from regional airports, and to Turkey and Greece from Jet2 bases. Alicante, Malaga and Palma have dozens of daily flights.

If you are flexible, look at less obvious airports such as Reus, Murcia or Almeria, which can be cheaper than the big ones. Check the transfer time and cost before you decide.

City breaks and staycations as alternatives

If the price of a summer holiday is too high, a city break in June or September, or a trip in the UK, may be a better option. Edinburgh, Cornwall and the Lake District are lovely, though also expensive in August.

Compare the cost of a week abroad with a week at home, and consider a short break instead of a long one. Our guide to cheap city-break flights from the UK covers short trips.

Insurance and the GHIC

The UK GHIC gives you access to state healthcare in the EU, but it does not cover repatriation or private treatment. Travel insurance is sensible for any holiday, and a family annual policy can be cheaper than buying separately.

Check the cover for medical costs, cancellations and baggage, and keep your documents with you. If you have a pre-existing condition, declare it.

Money-saving habits for a summer holiday

Book early, travel in the shoulder weeks, compare airports and packages, and travel light. Use a card with no foreign transaction fees, and book airport parking and transfers in advance.

Eat where locals eat, and use supermarkets for snacks. Small habits add up to a significant saving over a week, and make the holiday less stressful.

Mistakes to avoid

What goes wrong most is booking late for peak weeks, ignoring bag fees, choosing the cheapest fare without checking the transfer and forgetting passport validity.

Less obvious ones include taking children out of school without checking the rules, underestimating heat and not allowing enough time at the airport. A bit of planning avoids most of them.
