You keep meaning to book. The summer is quietly disappearing, the kids are getting restless, and every time you open a booking site you close it again because you have talked yourself into believing the price will drop if you just hold your nerve a bit longer.
So here is the question you actually want answered. If you are booking a summer holiday and leaving it late, when do you pull the trigger? A month before? A fortnight? The week you fly? The night before, sitting on the sofa at 11pm with your card in your hand?
The short version: for a package holiday, the sweet spot is roughly two to four weeks before departure. Not the night before. Not the morning of. Booking in the final few days is usually the worst thing you can do if the price is what you care about, because by then the cheap rooms and seats have gone and you are picking through the leftovers.
That is the headline. Now here is the full picture, with real numbers and the bits the deal sites tend to skip over.
First, how last minute is "last minute"?
The travel industry counts anything booked within about six weeks of departure as a last minute holiday. It used to mean booking days before you flew, but that has shifted. These days there are really two windows worth knowing:
The best-price window: two to four weeks before you go.
True last minute: inside the final 14 days.
Most of the genuine bargains live in that first window. The second one is more of a lucky dip, and the closer you get to the day itself, the more you are gambling on there being anything left worth buying.
When to book, broken down week by week
Since you asked it plainly, here is the plain answer, working backwards from your flight.
A month or more out (four weeks plus). You are a little early for the deep last minute discounts, but you have not missed anything either. Booking 31 to 45 days ahead still tends to come in cheaper than booking six months out, and you keep a proper choice of hotels and flight times. If you want a June or early July getaway, mid-April to mid-May is a solid time to lock it in.
Two to four weeks out. This is the one. For a seven-night package, around three weeks before you fly is generally the cheapest moment. For a shorter three-night break, aim for roughly four weeks ahead. This is when tour operators start marking down the flights and rooms they have not shifted, because an empty seat earns them nothing. Thomas Cook, On the Beach and eurochange all point to this same two-to-four-week pocket as the strongest window for package pricing, and it lines up with what the data shows.
The final week. Now it gets risky. Prices can still be good, but availability drops off a cliff. The specific hotel you had your eye on may be gone, family rooms and connecting rooms tend to vanish first, and what is left is often the stuff nobody else wanted. Sometimes you get a steal. Often you pay more for less.
The night before, or the morning of. Only for the genuinely flexible and the genuinely relaxed. You take whatever is going, from wherever it flies, and you do not get to be fussy. If you are a solo traveller or a couple who will happily go anywhere with a beach and a pool, you can occasionally pull off something ridiculous. If you are a family who needs two specific rooms in a specific resort in August, do not do this to yourself.
The catch nobody puts on the banner: last minute is not always cheaper
Here is the thing the "late deals" pages will not lead with. Leaving it late is a bet, and the bet only pays off when tour operators have over-ordered and are stuck with stock to clear.
When Which? tracked package prices across a summer, it found that in six of the ten countries it looked at, booking well in advance actually worked out cheaper. Last minute only won in the places where operators had misjudged demand and had too much to sell. Italy was a good example of the opposite: a week in Sicily booked eight months ahead came in around 340 pounds per person cheaper than the same trip left to the last minute. For a couple, that is nearly 700 quid left on the table for the sake of "seeing if it drops."
And there is one situation where holding out almost never pays: the school summer holidays. Demand in late July and August is already sky high, the cheaper room types sell out early, and once they are gone the price only climbs. If you are tied to those weeks because of school, booking early is nearly always the smarter move. Last minute rewards flexibility, and the school calendar is the opposite of flexible.
Why 2026 is actually a decent year to leave it late
That said, this particular summer is shaping up in the last-minute bookers' favour, so your instinct might not be daft.
In its latest research, published in mid-July 2026, Which? checked more than 17,000 package prices from easyJet Holidays, Jet2 Holidays and TUI, comparing what August trips cost back in March against what they cost now. August prices had dropped in 53 of the 71 European destinations it tracked, with some more than 200 pounds per person per week cheaper than they were in the spring.
The reasons are a mix of nervous demand around the eastern Med, higher jet fuel costs feeding into earlier pricing, and a clear shift in how people are booking. TUI told Which? that a lot more customers are holding off and booking much closer to departure than they used to, which is exactly what has driven those late August prices down. In other words, half the country is playing the same waiting game you are, and it has softened the market.
So this year, if you are flexible, leaving it late has legs. Just know that this is a market condition, not a permanent law. Next summer could easily flip back.
The cheapest last minute destinations right now
If you are ready to book and want to point yourself at where the value actually is, this is where 2026's August prices have fallen the hardest, based on that same Which? tracking. All figures are the average cost per person for a week, flights included, if you book now. If none of these grab you, our full rundown of the best summer holiday destinations for 2026 casts a wider net.
Dalaman area, Turkey, from around 808 pounds per person. The cheapest region this summer, down about 14 percent since March. The catchment runs along the Turquoise Coast from Fethiye and Oludeniz across to Marmaris and Icmeler. Calis, with its long promenade and its sunsets, is the better-value pick of the bunch at roughly 867 pounds.
Kefalonia, from around 829 pounds. Down about 11 percent, and worth flagging because it also topped Which?'s recent survey of the best Greek islands. Base yourself around Trapezaki or Lourdata for the quieter beaches.
Costa Dorada, Spain, from around 832 pounds. The cheapest Spanish stretch this year, south of Barcelona. Salou and Cambrils have come down, but Tarragona nearby gives you a Roman amphitheatre and an old town without the crowds.
Gran Canaria, from around 851 pounds. Down about 14 percent, and reliable year round if you fancy the same trip in winter.
Costa Blanca, Spain, from around 859 pounds, and Tenerife, from around 866 pounds (down 10 percent).
Malta, from around 869 pounds, and the Costa Brava, from around 878 pounds.
The Peloponnese, Greece, from around 903 pounds. The biggest percentage drop on the list at 16 percent, and a good shout if you want mainland Greece with far emptier beaches than the islands.
The single biggest faller, though, was the Algarve. A week there in August averaged 1,313 pounds per person back in March. Book it now and you are looking at closer to 1,100. Alvor and Tavira are the picks if you want the coastline without the July-August scrum.
Package or do-it-yourself? Why booking your own flights is the trap
There is a reason all of this advice keeps pointing at package holidays rather than booking flights and a hotel separately.
Flights are the part that punishes you for leaving it late. As a rule they get more expensive the closer you get to departure, not cheaper. The cheap fare classes sell first, and by the final three weeks you are buying from the pool of seats aimed at business and emergency travellers who have no choice but to pay. Occasionally an airline dumps unsold seats on a quiet route, but that is rare and you cannot plan around it. Skyscanner's own advice is blunt about it: last minute flights getting cheaper is the exception, not the rule.
Packages behave differently because tour operators buy flights and hotel rooms in bulk, months ahead, and an unsold block is money burning a hole in their accounts. When they need to shift stock late, they discount the whole bundle, which is how a last minute package can beat the same flights and hotel bought separately. That is the mechanism doing the work in those two-to-four-week deals.
If you would still rather build your own trip, book the flights one to three months out for short-haul Europe and treat anything inside two weeks as a premium you are choosing to pay for the flexibility. There is a whole other set of tactics for finding cheap flights worth knowing if you go down that road.
Where to book a last minute holiday
Once you know when, the where is easier. A few options, depending on how you like to shop.
Comparison sites are the sensible first stop, because they show you the same holiday across multiple operators and let you filter by budget and departure airport. TravelSupermarket lets you book right up to the day before you fly, and covers departures from all the major regional airports, so if you are flying from Manchester, Liverpool, Birmingham or Newcastle you can see what is going from your doorstep rather than being funnelled through Gatwick.
Booking direct with the big operators is worth it once you have a destination in mind. loveholidays, On the Beach, TUI and Jet2 Holidays all run dedicated late-deals sections. Jet2 Holidays is the pick of them on paper: it is now the UK's biggest tour operator and one of the few beach-holiday firms to hold Which? Recommended Provider status, having topped the Which? package survey for customer service more or less every year. TUI is the giant for long-haul and family holidays, but Which? rates it below Jet2 for beach breaks, so it is worth comparing the two before you commit. lastminute.com, Travel Republic and Hays Travel are worth a look too.
One non-negotiable: check the holiday is ATOL protected before you pay. Any flight-inclusive package from a proper operator will be, and it means your money and your trip home are covered if the company goes under while you are away. At the last minute it is tempting to grab the first cheap thing you see. Do not skip this bit.
How to actually squeeze the price down
The deals reward flexibility more than anything else, so the more of these you can say yes to, the better you will do.
Be open on where you go. If you are choosing between four sunny resorts rather than one exact hotel, you have four times the chance of landing on a good drop. Pick the destination by the best price, not the other way round.
Fly midweek. A Tuesday or Wednesday departure is usually cheaper than a Friday or Saturday, because fewer people want it. Shifting your trip by a single day either side can move the price more than you would expect.
Check nearby airports. Compare a few regional airports rather than defaulting to one, but factor in the cost and faff of getting there before you celebrate.
Set price alerts. If you have a rough date and destination, let Skyscanner or the comparison sites watch the price for you rather than refreshing the page ten times a day. Ignore the old "always cheapest on a Tuesday" myth for the day you book, though. The data does not back it up. What matters is the window, not the weekday.
The bottom line
If you are leaving a summer holiday late and want the cheapest price, aim to book two to four weeks before you fly, lean towards a package over booking your own flights, stay flexible on where you go and which day you leave, and check it is ATOL protected before you pay.
Do not book the night before expecting a miracle, and do not gamble on a last minute drop if you are locked into the school holidays, because that is exactly when waiting costs you. But this particular summer, with August prices down across most of Europe, holding your nerve for a two-to-four-week deal is a bet that is genuinely worth making. Turkey's Turquoise Coast and the quieter corners of Greece and Spain are where the money goes furthest right now.
