How long is the flight from London to Paris?

A direct flight between London and Paris takes 1 h 10 to 1 h 25. Based on route schedule data (FlightsFrom, Skyscanner, FlightConnections):

  • LHR → CDG (Heathrow ↔ Charles de Gaulle): ~1 h 15–1 h 25. British Airways and Air France, with very high frequency (BA can run 40+ flights a week on this pair).
  • LGW → CDG (Gatwick ↔ Charles de Gaulle): ~1 h 15–1 h 20. easyJet leads the low fares.
  • LGW/STN → ORY (Gatwick or Stansted ↔ Orly): ~1 h 25–1 h 35. Vueling is the dominant carrier at Orly.

The fastest flight is around 1 hour 10 minutes, but that’s time in the air only — add the airport transfers (below), where the train clearly wins.

Which airlines fly the route (and which are cheapest)

The market splits between premium carriers and low-cost airlines, which is great news for your wallet:

  • British Airways — dominates LHR ↔ CDG. Ideal if you want checked baggage, lounges, or Oneworld connections.
  • Air France — flies to CDG (and sometimes Orly) from Heathrow and Gatwick. Strong for morning and afternoon corporate travel.
  • Vueling — owns the routes into Orly from Gatwick and Stansted. Competitive fares if you travel light.
  • easyJet — the low-cost powerhouse on Gatwick ↔ CDG, with one-way fares that can drop below £25.
  • Ryanair — the cheapest of all, but to secondary airports: Stansted ↔ Beauvais (BVA), about 85 km from Paris.

Golden rule: on this route, low-cost carriers set the price floor. Before you book, compare all London–Paris flights at once on TopTravelCentre to see instantly which airline and airport is cheapest for your dates.

Airports: where you land (and take off) matters a lot

On London–Paris, the airport is almost everything: it changes the price, the total travel time, and the transfer cost.

London: five options

  • Heathrow (LHR) — the big hub, best connected (Elizabeth / Piccadilly Line). Priciest, but fastest to the center.
  • Gatwick (LGW) — easyJet’s base and Vueling’s strong point to Orly; a good price-and-connection balance (Gatwick Express ~30 min).
  • Stansted (STN) and Luton (LTN) — Ryanair and easyJet territory: lowest fares, but far out (Stansted Express ~45 min).
  • London City (LCY) — the most central, business-only; high fares.

Paris: three options

  • Charles de Gaulle / Roissy (CDG) — the international hub; RER B to the center in ~35 min.
  • Orly (ORY) — south of the city, often closer than CDG and cheaper (Orlyval or tram T7).
  • Beauvais (BVA) — ~85 km out, Ryanair only; the shuttle takes ~75 min. The cheapest ticket, but watch the time and bus cost.

Often-forgotten tip: the cheapest ticket isn’t always the cheapest. Add the airport-to-center transfer before deciding. A flight that’s £25 pricier into CDG can end up cheaper than one into Beauvais once you pay the bus and lose two hours. Compare prices by airport on TopTravelCentre.

Plane vs Eurostar: when is flying worth it?

The big difference between London–Paris and other routes: the Eurostar runs center-to-center (St Pancras ↔ Gare du Nord) in about 2 h 15 non-stop (over 400 million passengers since 1994). That’s why most leisure traffic moves by train.

Choose the plane if you fly from/to Gatwick, Stansted, or Luton and grab a low-cost sale fare (sometimes under £25 one-way), connect to another flight, or travel as a group. The Eurostar wins if you go center-to-center —door-to-door is often faster than flying, with no security queues or airport transfers— or if you travel light and value comfort.

If you decide to fly, search your London–Paris flight on TopTravelCentre (all airports at once) and compare it with the Eurostar website before you commit.

When is the cheapest time to fly to Paris?

Data from search engines like Skyscanner, KAYAK, and Expedia agree on the lowest-demand (and therefore cheapest) months:

  • March — the consistently cheapest month (end of winter, low demand).
  • January — after the holidays, prices collapse.
  • February and November — also affordable, outside school breaks and holiday peaks.

When to avoid: July, August, May bank holidays, Christmas, and Easter (demand pushes prices up). If summer is your only option, fly mid-week and book early.

7 real tactics to get the cheapest flight

  1. Fly Tuesday, Wednesday, or Thursday. The cheapest days of the week; weekends always cost more.
  2. Book 1–3 months ahead. Not too early, not last-minute: that’s the sweet spot for European routes. (Learn more in our guide on how far in advance to book a flight.)
  3. Compare airports, not just dates. Orly and Gatwick are usually cheaper than CDG and Heathrow.
  4. Round trip, almost always — and on the same airline when possible.
  5. Stay flexible on dates. Shifting by a day can save 20–30%.
  6. Travel light when you can. Low-cost carriers discount the base fare; checked bags cost extra.
  7. Use a metasearch that groups every airline. The fastest way to never miss a deal. For more tactics, read our tips to find cheap flights that actually work.

How much does a London–Paris flight cost? (price ranges)
