Published October 12, 2026
Looking for cheap flights to UK? Fares to the UK change constantly, but knowing when to book and which airport to use can save you a lot. Here's what to know.
Airports serving UK
Most travelers arrive at London Heathrow (LHR), Gatwick (LGW), Manchester (MAN), Edinburgh (EDI) and Birmingham (BHX).
Cheapest time to fly to UK
Fares are usually lowest in January to March and November. The best weather is generally May to September, when prices rise — book 2–4 months ahead if that's when you'll go.
Our top money-saving tip
Manchester and Edinburgh can be cheaper entry points than London.
Tuesday, Wednesday and Saturday departures are often cheaper, and staying flexible by a day or two can cut the fare.
Why visit UK
Travelers love the UK for London, the Scottish Highlands, historic cities and countryside.
Before you go
Check if you need a UK ETA or visa before travel. Always confirm entry rules with official government sources before you fly.
