Book Cheap Flights to London

London pulls you in for all kinds of reasons. Some go for the history. Others for the food. And then there are people who just want to wander along the Thames with a coffee in hand. Whatever your reason, one thing stays the same: The need for affordable tickets. To snag cheap flights to London do not expect accidental ‘miracles. It takes timing, openness & sometimes a bit of luck. But with HolidayGlobes, you are not left guessing.

When Should I Book Flights to London for the Lowest Fares?

To wait too long is risky for London flights. Book too early and you might miss later price drops. The sweet spot? Around two to three months before your travel date.

If you’re planning a summer trip, start looking even earlier. London gets busy from June to August. Flights fill up fast and prices climb.

For the cheapest rates, target these months:

• January
• February
• Early March

Mid-week departures (Tuesday / Wednesday) come with lower flight fares. Red-eye flights or odd-hour departures are mostly cheaper too. And don’t forget to check different days for your return trip. To fly back on a Saturday might cost more than returning on a Tuesday.

Which London Airport Should I Select for Cheap Tickets?

Most international flights land at London Airport Heathrow (LHR). It’s the biggest and busiest. But sometimes Heathrow isn’t the cheapest.

Other airports include:

• Gatwick (LGW) – Good for European budget carriers
• Stansted (STN) – Heavy on low-cost airlines
• Luton (LTN) – Another budget option

If your goal is pure savings, widen your search. Many budget airlines fly into Gatwick, Stansted, or Luton.

When you search for London tickets, tick “All London airports” if that option shows up. Sometimes landing at Stansted and taking a short train into the city saves you hundreds.

Can I Fly to Bangkok or Barcelona from London in Budget?

Yes, and here’s where it gets fun. Once you’re in London, use it as your jump-off point. A lot of travelers do this to stretch their trips. For example:

• Look for flights to Thailand from London on pocket-friendly airlines. Round-trip fares to Bangkok from London often go on sale.
• Heading into Europe? Flights to Barcelona from London are super common & often dirt cheap. Low-cost carriers like Ryanair and easyJet offer them for as low as $30 if you book early.
• When flying long-haul into London, think of building a multi-leg trip from there. Just watch layover times and airport transfers between flights.

How do I Grab Cheap Flights to London?

This is what helps (without the usual generic advice):

• Set fare alerts. Let websites ping you when prices drop.
• Search in incognito mode. Avoid price jumps from repeated searches.
• Be open to nearby airports for both departure and arrival.
• Don’t ignore budget airlines. Even for long-haul routes: Some lesser-known airlines offer solid deals.
• Book one-way segments if needed. Sometimes two separate one-way tickets work out cheaper than a round trip.
• When searching for cheap tickets to London, don’t just refresh one site over and over. Cross-check prices on a few platforms.
