Ask frequent travellers where their holiday budget disappears and most will say the same thing: the flight. On long-haul routes or during school holidays, a ticket can cost more than a week's accommodation. Which is exactly why airfare is where a bit of method pays off — knock £100 off the fare and you've just funded an extra night away, a nicer hotel or a very good dinner.
The single biggest lever is flexibility. Fares move constantly with demand, season and how full the plane is, so the less rigid your dates and airport, the more those swings work in your favour. If you can shift a trip by a day or two, or fly from a nearby city instead of your home airport, you're already ahead of most people searching.
The second lever is how you search. Juggling a dozen airline sites in separate tabs is slow and you'll still miss things. Comparison platforms pull fares from many carriers into one view so you can sort by price, duration or stops — Kiwi.com, which commissioned this guide, lets you compare routes, flexible dates and nearby airports in a single search, and some platforms can even combine flights from airlines that don't normally sell each other's tickets, which occasionally produces itineraries a standard search would never show. The catch: check connection times carefully and find out what happens if one leg is delayed before you commit. Pair this with price alerts — set one for your route and let the deal come to you instead of checking fares every morning.
The third lever is the one people skip: the total cost. The cheapest number on screen is rarely the cheapest trip. Budget carriers and bare-bones fares often hide their real price in add-ons — checked bags, cabin bags, seat selection, card fees, airport transfers from secondary airports. Before you pay, add up what the journey will actually cost you door to door. A fare £30 higher on a search result can easily be £50 cheaper once bags and transfers are included.
None of this requires luck or insider contacts. It's a repeatable routine: stay flexible on dates and airports, compare widely in one search, set alerts and do the boring maths on the full price. Do it consistently and the savings compound across a year of trips — money that's far better spent at your destination than in the air.
One honest note: this piece comes via a partnership with Kiwi.com, so treat the platform recommendation as a starting point rather than the only option. The underlying advice — flexibility, alerts and total-cost thinking — works with any comparison tool or airline site you like.
Who's this for? Anyone booking their own flights, but especially families locked into school holiday dates (flex on airports instead) and long-haul travellers, where even small percentage savings translate into serious money.
