How to find cheap flights from Paris to London

The Paris–London route is short enough that airlines compete hard on price, which works in your favour if you know when and how to look.

  • Book 3 to 8 weeks ahead. Last-minute fares on this route rarely drop; they climb. The sweet spot for low-cost carriers is usually about a month out.
  • Fly midweek. Tuesday and Wednesday departures are consistently the cheapest days, while Friday and Sunday carry a premium from both business and weekend travellers.
  • Compare all four London airports. Flights land at Heathrow, Gatwick, Luton and Stansted, and the difference between the cheapest and most expensive airport can exceed the fare itself once you factor in transfer costs.
  • Set fare alerts. Prices on this route swing by 30–40% week to week. Run a search on TopTravelCentre and check the calendar view for the cheapest dates in the month.

Paris and London airports: which to choose

From Paris, you have two realistic options:

  • Charles de Gaulle (CDG) — the main hub, with the widest choice of flights and times, including most full-service departures to Heathrow. Connected to central Paris by the RER B train in about 35 minutes.
  • Orly (ORY) — closer to the city and often cheaper, especially for full-service flights to London City and low-cost departures. The Orlyval metro link reaches central Paris in roughly 30 minutes.

On the London side:

  • Heathrow (LHR) — best if central London west side is your destination; the Elizabeth Line gets you to the centre in under 40 minutes.
  • Gatwick (LGW) — strong low-cost schedule; the Gatwick Express reaches Victoria in about 30 minutes.
  • Luton (LTN) and Stansted (STN) — usually the cheapest fares, but both sit 45–60 minutes from central London by train or coach. Add the transfer cost before deciding the fare is a bargain.
  • London City (LCY) — a short hop from Orly; ideal if you are heading to Canary Wharf or the City, though fares tend to run higher.

Airlines flying from Paris to London

This route has genuine variety, so think about what matters most — price, timing or luggage.

  • Full-service options operate the dense shuttle-style service between Charles de Gaulle and Heathrow, with flexible tickets, included cabin baggage and frequent departures from early morning to evening. If your plans might change, a flexible ticket here can beat a cheap non-refundable fare.
  • Low-cost carriers fly from both Paris airports to Gatwick, Luton and Stansted, with headline fares that can drop below €30 in low season. Watch the add-ons: a cabin bag, seat selection and airport transfers can double the real cost.
  • Corporate-friendly flights from Orly to London City suit business travellers who value the fastest door-to-door time to the financial district rather than the lowest fare.

For most leisure travellers, the best move is simple: compare every Paris–London flight on TopTravelCentre, filter by total price including bags, then pick the airport pairing that suits your London base.

Best time to fly: price trends by season

  • Cheapest months: January, February and November. Winter weekdays outside school holidays regularly show the lowest fares of the year.
  • Most expensive: late June and July, plus the Christmas and Easter holiday weeks. Summer weekends on this route sell out early at high prices.
  • Time of day: early morning and late evening departures are usually cheaper than the 7–9am business peak.
  • Events to plan around: fashion weeks, major matches at Wembley and the marathon push fares up sharply for specific weekends — book those dates well ahead or shift a day.

Money-saving tips for this route

  1. Price the train as a benchmark, then beat it. The Eurostar is convenient, but advance-purchase plane tickets are often dramatically cheaper — the trade-off is airport time. On a strict budget, flying usually wins.
  2. Travel hand-luggage only. Bag fees are where low-cost airlines make their margin. A backpack and a compliant cabin bag keep your fare near the headline price.
  3. Check both Paris airports. Orly and CDG fares often differ for the same day; the difference can pay for your airport transfer.
  4. Book the return as two one-ways. On this route, mixing carriers for outbound and return is frequently cheaper than a round trip with one airline.
  5. Fly into the airport nearest your hotel’s side of London. A €15 saving that costs you £25 in cross-city travel is not a saving.

FAQ

How long is the flight from Paris to London? Around 1 hour 15 minutes in the air. Door to door, expect 4 to 5 hours including airport time and transfers.

What is the cheapest day to fly? Tuesdays and Wednesdays in low season (January, February, November) are reliably the cheapest combinations.

Do I need a visa? France and the United Kingdom are both outside each other’s common travel areas, so you pass passport control. EU ID cards are no longer accepted for most travellers to the UK — carry a valid passport.

Is it cheaper to fly or take the train? Advance-purchase flights are usually cheaper than walk-up train fares, especially midweek. The train wins on city-centre-to-city-centre time.

Which London airport is closest to central London? Heathrow via the Elizabeth Line and London City via the DLR offer the fastest central connections, but compare the full fare picture before choosing.
