How to save big on summer holidays.
Early planners can count on our data insights to uncover bang-for-your-buck summer destinations that don’t skimp on experiences – whether it’s sun-kissed beaches in Europe or far-flung escapes across the globe. We’ll guide you to hidden gems that are easy on the wallet, but also dish out destinations with prices where you’ll likely do a double take – adding an extra level of consideration to your travel plans.
European bargains:
Mediterranean coasts take the crown.
Want to stretch your pounds while exploring Europe? Lisbon stands out as our best-value destination, with return flights averaging £173. It offers a delightful blend of city charm and endless beaches to boot. With nearly a third of the Mediterranean coastline, Spain and Italy are also topping our radar for budget-friendly summer getaways. These countries offer several spots that combine culture with easy access to gorgeous beaches. For a change of pace, Albania is making its mark this summer again. You’ll find plenty of sunshine and beaches that can compete with the Caribbean without the hefty price tag – for flights and hotels.
Wander far, spend less:
from Asia to the U.S.
Who says long-haul travel has to cost an arm and a leg? North Africa is making waves, with Marrakech costing as little as £240 for return flights on average and Algiers following at an average of £316. North America is also in the mix, with Toronto, Miami, Chicago and Los Angeles all within budget reach. And if Asia is calling your name, Seoul and Jakarta are ready for you, with return economy flights averaging £660 and £683 respectively - just be mindful of rain and typhoon season when planning your trip.
Travel price peaks.
KAYAK's flight search data reveals many affordable options, but here it also highlights destinations where prices are on the rise. And it looks like price increases in some destinations could test your wallet next summer. These increases add an extra layer of planning and booking consideration if you’re aiming to keep your budget in the black.
Priciest destinations.
If you're thinking of a trip to Down Under, you'd better brace yourself - return flights to Brisbane, Auckland and Perth cost an average of £1,417, £1,336 and £1,270 respectively. Trips there are worth every penny, of course - if you’ve got enough of them.
Biggest price increases.
You might also want to save a bit extra for some closer escapes. Flight prices to Dublin are set to rise by 50% over the next year, while Bucharest and Lahore will see increases in flight prices of 23% and 18% respectively.
Buzz-worthy summer destinations.
Dreaming big for 2025? Then dust off your jumbo suitcases - because Brits are apparently setting their sights on far-flung adventures in Africa, Asia, and Australia for next summer, with major jumps in flight searches compared to last year. See which trending hotspots are catching British travellers’ attention.

Tips from Rachel Mumford, KAYAK'S UK Travel Expert.
European steals.
France and Türkei, two of my summer favourites, are looking more affordable next summer. Prices are dropping 16% and 10% respectively compared to this year.
Savings at your doorstep.
I’ve always believed you don’t need to go far to find something special. From coastlines to countrysides, the UK is full of summer treasures. And with domestic flight prices down 19% versus last year, it’s a great time to enjoy a staycation.
Long-haul deals.
I love a bargain, so these long-haul deals are hard to ignore. Japan, Australia, and Indonesia offer price drops of 18%, 7%, and 6% year-on-year. Pair that with favourable exchange rates, these are too good to miss.
Fancy flying.
I’m often asked if upgrading to premium class is ever worth it. With Business and First-Class searches up 31% and 21% respectively, but prices staying steady, next summer might just be the time to indulge.
