20 Cheap Flights This Summer from London Under 3 Hours Away

20 Cheap Flights from London Under 3 Hours Away

(Return Flights starting from £25)

“If there is one thing I’ve learned after travelling to over 30 European countries, it’s this: cheap flights from London this summer are everywhere if you know where to look.”

Europe is easily my favourite place to travel. It is so close (under 3 hours flight time), so diverse, and every destination feels completely different. One weekend you are in Italy, the next you are in Eastern Europe, and it can cost less than a night out in London.

Over the years, I have made it a rule to never pay more than £50 for a one-way flight in Europe, and most of the time, I do not even get close to that.

In this guide, I’ll show you exactly how I find the cheapest places to fly from London, and more importantly, 20 of the cheapest flights from London you can actually book this summer under 3 hours flight time away..

Why Look for Cheap Summer Flights from London?

Are Cheap Flights Really That Easy to Find?

Short answer: yes.

Flights around Europe are some of the most competitive routes in the world. Budget airlines are constantly lowering prices to fill seats, which is why you’ll regularly see return flights for £25 to £60. If you are looking for cheap summer flights from London, there are often more options than people realise.

I have even managed to fly for £1 before using promo codes, so deals do exist if you are paying attention.

That said, £25 to £50 return is the realistic sweet spot for many cheap European flights from London, especially if you are flexible.

What Should You Check Before Booking?

Always check:
