The timing of your booking matters almost as much as where you’re going. A package holiday to Majorca in the school summer holidays costs 40 to 80 per cent more than the same trip in late September. Book in January and the major UK operators are running their biggest deals of the year. Understanding these patterns lets you travel to the same places for significantly less money, or upgrade your accommodation for the same budget.
This guide covers when UK holiday prices are lowest, how school holidays inflate costs, the shoulder season windows that deliver the best value, and how far ahead you need to book for different holiday types.
When are UK holidays cheapest?
October and November are the cheapest months for most package holiday bookings. Once schools return in September, demand drops sharply and operators cut prices to fill remaining capacity. Late October to mid-November is often the lowest-cost window of the entire year for Mediterranean sun holidays.
February is the second cheapest window, outside of ski resorts and half-term weeks. Winter sun destinations such as the Canary Islands see some of their lowest prices between late January and mid-February.
The worst months for prices are the last two weeks of July and all of August, when school summer holidays drive a demand spike that affects flights, hotels, and package prices simultaneously. The week before and after Easter is similarly inflated.
For flights specifically, the cheapest booking window is different from the cheapest travel month. Our full guide to when flights are cheapest covers the data on timing by destination and season.

Is the January sale worth it?
Most major UK holiday operators launch their January sales in the first two weeks of the new year. TUI, Jet2, easyJet Holidays, and Lastminute.com all offer discounts on summer packages, typically 15 to 25 per cent off headline prices. For families who know which destination and week they want, these savings are real and significant.
The catch: you are committing 6 to 9 months ahead. If plans change, amendment fees apply. Some operators charge £25 to £50 per person to change travel dates. The January sale works best if you have already decided on a destination and are willing to commit to a specific week.
For airline-specific sale dates, see our guides to Ryanair sale dates, easyJet sale dates, and TUI sale dates. Package operators typically run their January sales from 2 January for two to three weeks.
Late November, covering Black Friday and Cyber Monday, is a second major sales window. Most operators now treat it as equivalent to the January sale. If you miss one, the other usually offers comparable discounts on the same summer packages.
How much do school holidays add to the cost?
School holidays inflate prices because millions of families can only travel in specific windows. Operators know demand will be there and price accordingly. The summer holidays are the worst offender, followed by Christmas and Easter.
A family of four booking a package to Greece in the last week of July or August can expect to pay £600 to £1,200 more than the same accommodation and flights in the first or second week of September. That is not a single operator’s markup; it is a market-wide supply and demand effect.
The table below shows typical price premiums by school holiday period, based on popular Mediterranean and short-haul destinations from UK airports.
| School holiday | Typical dates | Price premium | Best alternative window |
|---|---|---|---|
| Summer | Late July – end August | +40 to 80% Highest | First three weeks of September |
| Christmas | 19 Dec – 5 Jan | +30 to 60% Very high | Late November or 7–20 January |
| Easter | Two weeks around Easter | +20 to 50% High | One week either side of Easter |
| October half-term | Last week Oct – first week Nov | +10 to 30% Moderate | Mid-October or mid-November |
| February half-term | Two weeks mid-February | +10 to 20% Lower | Early February or early March |
One practical point: school holiday dates vary by region. England, Scotland, Wales, and Northern Ireland do not all break at the same time. If your children are in Scotland, your Easter break typically falls a week earlier than in England. That one-week shift can save £200 to £400 on a family package by avoiding the English school holiday peak.
The first and last weeks of the school summer holidays are also usually cheaper than peak mid-August. If you have any flexibility within the school holiday period, the first week of July and last week of August tend to be the lower-cost options.

The shoulder season sweet spot
Shoulder season is the period just before and after peak. For Mediterranean beach holidays from the UK, this means May, June, and September. These months offer conditions close to peak summer at significantly lower prices.
September is the single best month for European beach holidays if you have flexibility. Sea temperatures across the Mediterranean are still warm, typically 22 to 25°C at the surface. Air temperatures in southern Spain, the Greek islands, and the Algarve hold in the mid to high 20s for most of the month. The beaches are quieter, flights are cheaper, and restaurants are easier to book.
For European city breaks, October and early November are the shoulder season. Prague, Lisbon, Barcelona, and Rome are all noticeably quieter and cheaper in October than at any point between May and September. The weather is cooler but generally dry in October across most of southern and central Europe.
November is the cheapest month for city breaks in most years, though weather becomes less reliable. It is particularly good value for Lisbon, which stays mild through much of November and is drier than northern European cities. See our budget guides: Prague, Lisbon, Barcelona, and Rome.

For long-haul destinations, shoulder season varies by climate. Thailand’s shoulder from the UK is April to May and October to mid-November, between the dry-season crowds and the monsoon. Dubai’s shoulder falls in April, May, and October, between the extreme summer heat and the peak winter season from November to March. Full details are in the destination guides below.
How far ahead should you book?
The right booking window depends on what you are booking and when you want to travel. Package holidays to peak school holiday dates and last-minute flexible breaks follow entirely different logic.
Summer packages during school holiday weeks are the category where early booking matters most. Availability is limited: the number of direct flights to popular Mediterranean destinations in August is finite, and the best accommodation sells first. Booking 9 to 12 months ahead gives the most choice and, in most cases, a lower price than waiting for demand to build.
City breaks and off-peak travel follow different logic. Booking 6 to 10 weeks ahead for a European city break typically delivers good availability at competitive prices, because airlines and hotels discount unsold seats and rooms in this window.

| Holiday type | Booking window | What happens if you wait |
|---|---|---|
| Summer package, school holidays | 9–12 months ahead | Availability drops, prices rise |
| Summer package, non-school dates | 3–6 months ahead | Some last-minute availability |
| European city break | 6–10 weeks ahead | Flight prices rise in final 2 weeks |
| Long-haul flight-only | 3–6 months ahead | Prices spike sharply in final 3 weeks |
| Caribbean or Indian Ocean | 6–10 months ahead | Limited direct capacity from UK |
| Last-minute, flexible | 2–4 weeks before departure | Good packages appear but choice is limited |

Best time to visit by destination
We have published in-depth month-by-month guides for 10 of the most popular UK holiday destinations. Each covers weather conditions by month, the UK school holiday price impact, which airports fly direct, and the specific window that gives UK travellers the best combination of conditions and value.
- Best time to visit Tenerife from the UK: a year-round sun destination, but January to March offers the lowest prices outside school holiday weeks.
- Best time to visit Majorca from the UK: May and late September for the best balance of heat, quiet beaches, and value.
- Best time to visit Greece from the UK: June or September to avoid August crowds and the new daily visitor caps introduced on some islands in 2026.
- Best time to visit Turkey from the UK: April to June or September to October for the best conditions and price-to-quality ratio.
- Best time to visit Barcelona from the UK: May or October for the city at its quietest, with the Sagrada Família centenary making 2026 a particularly good year to visit.
- Best time to visit Portugal from the UK: September for the Algarve, when temperatures are still high and crowds have thinned; May for Lisbon and Porto.
- Best time to visit Lanzarote from the UK: October is ideal, with warm weather, fewer crowds, and the La Geria wine harvest adding a reason to go beyond the beach.
- Best time to visit Dubai from the UK: November to March for comfortable temperatures; avoid June to September when daytime heat regularly exceeds 40°C.
- Best time to visit Thailand from the UK: November to March for the main dry season; the two-coastline rule matters if you are travelling outside these months.
- Best time to visit New York from the UK: April to June or September to November for the best weather and the most competitive transatlantic fares.
Last-minute deals: are they worth it?

Last-minute packages, booked two to four weeks before departure, can be good value when operators have unsold capacity to shift. The trade-off is limited choice. You pick from what remains, not from the full catalogue. Destination, departure airport, accommodation standard, and board basis are all constrained by what is left.
Last-minute deals work best in shoulder and off-peak periods. In peak school holiday weeks, the demand is reliably there and operators have little incentive to cut prices.
A separate category worth knowing about is error fares, which are pricing mistakes by airlines or booking platforms that create short windows of dramatically low prices. These are unrelated to the booking calendar. Our guide to error fares covers how to spot them, how to book them, and what happens if the airline tries to cancel.

Frequently asked questions
What is the cheapest month to book a UK holiday?
Late October to mid-November is typically the cheapest period for immediate travel to Mediterranean sun destinations, as operators discount remaining capacity once schools return. For advance bookings, January is when major operators run their biggest sales on summer packages, with discounts of 15 to 25 per cent on headline prices.
When are UK holiday prices highest?
The last two weeks of July and all of August are the most expensive, driven by school summer holiday demand. Christmas and New Year (roughly 19 December to 5 January) is the second most expensive period. Easter fortnight is the third peak. All three are driven by the same supply and demand dynamic.
Should I book my summer holiday early or wait for a deal?
If you need to travel in school holidays, book early, ideally 9 to 12 months ahead. Availability at popular Mediterranean destinations in peak school holiday weeks is limited, and prices tend to rise as summer approaches. If you have flexibility on dates and can travel outside school holidays, booking 3 to 6 months ahead is sufficient.
How much cheaper is shoulder season compared to peak?
For Mediterranean beach holidays, September is typically 20 to 40 per cent cheaper than August for the same package. October and November are cheaper still, though with cooler and less reliable weather. The exact saving depends on the destination, operator, and specific accommodation.
Does it matter which week within the school holidays I travel?
Yes. The first and last weeks of the school summer holidays are usually cheaper than the peak mid-August fortnight. If your children are in Scotland, Easter falls a week earlier than in England, which can save £200 to £400 on a family package by avoiding the English school holiday peak. Small date shifts often produce meaningful savings.
Are package holidays always more expensive during school holidays than booking separately?
Not necessarily. Package operators negotiate bulk rates on flights and hotels that individual travellers cannot access. In peak periods, a package is often comparable to or cheaper than booking separately. The premium in school holidays is relative to the same package outside school holidays, not to DIY booking.
