Is a train or plane cheaper from London to Paris?

What is the cheapest flight from London to Paris?

According to Skyscanner (flight comparison site), the cheapest one-way flight from London to Paris starts around €62, typically on budget carriers like Ryanair or easyJet. That price usually applies to off-peak routes such as London Stansted to Paris Beauvais — airports well outside the city cores. Business Insider reported a same-day scenario where a Vueling flight from Gatwick cost £31, while the cheapest Eurostar ticket that day was £97. That extreme gap shows flights can undercut trains when you shop aggressively.

What is the cheapest Eurostar ticket?

Eurostar’s U.S. website lists tickets from $52 (roughly £42.50) one-way, while Trainline (train booking platform) shows advance fares starting from $73.29. The catch: those cheap train seats sell out fast, and same-day walk-up prices can be three times higher. Omio’s travel comparison puts the average train price at €103, versus €55 for a flight — reinforcing that last-minute train travel usually costs more.

Comparison of flight and train prices

5 data points, one pattern: flights win on headline price when booked early, but lose on extras.

Mode Cheapest one-way Average one-way Baggage fees Airport transfer cost
Flight (budget) €62 €55–€100 €10–€30 €10–€25
Eurostar £42.50 €103 None None (central stations)
Bus €25 €34 None None
Bottom line: Budget fliers can beat train prices, but only if they subtract the cost and hassle of getting to outlying airports and paying for luggage. For most central London travelers, the train’s all-in price is competitive once those extras are factored in.
Why this matters

A £31 flight from Business Insider’s example looked dirt cheap, but add £20 for a suitcase and £12 for a Gatwick Express ticket, and the total hits £63 — still less than the £97 Eurostar that day, but not dramatically so.

The pattern shows that the cheapest option depends on how you account for extras.

How long is a flight from London to Paris today?

Average flight time

The flying time between London and Paris is about Klook travel blog 1 hour 15 minutes, but the total journey — including check-in, security, boarding, taxiing, and baggage claim — typically stretches to Klook travel blog 3 to 4 hours. That’s more than double the air time and still longer than the Eurostar’s city-center-to-city-center time of around 2 hours 20 minutes.

Flight time from different airports

The actual flight duration varies by departure and arrival airports. London Heathrow to Paris Charles de Gaulle is the longest route (about 1h20min), while London City to Paris Orly can be slightly quicker. Budget airlines often use Stansted or Luton, adding an extra 30 minutes of flight time due to approach patterns.

Trip.com and Google Flights let you see today’s exact departure and arrival times. For the most current schedules, check the airline’s own site or a reputable aggregator like Skyscanner.

Bottom line: The flight itself is short, but the full travel day rivals the train once you include airport transfers. For travelers near an outer London airport, the time gap narrows.

The time advantage of the train is clear for central travelers.

What is the cheapest way to get from London to Paris?

Compare prices: flight vs train vs bus vs ferry

Omio (multi-modal travel aggregator) consistently lists the bus as the cheapest option, with average prices around €34 and tickets as low as €25. Trains average €103 (but can drop to £42.50 on advance bookings), and flights average €55. Ferries (Dover–Calais with a connecting train) run about €30–50, but the total travel time exceeds 8 hours.

Booking tips for cheapest fare

  • Book flights 6–8 weeks ahead for the best deals (Skyscanner)
  • Eurostar cheap tickets are released up to 11 months in advance; grab them early (Eurostar)
  • Bus companies like FlixBus and BlaBlaCar Bus offer flexible cancellation and frequent sales (Omio)
  • Compare total costs including luggage, meals, and transfers (see table above)

Price range from €25 to €120

The price spectrum is wide: bus from €25, train from £42.50, flight from €62, ferry combo ~€40. The cheapest overall mode is the bus, but it takes 7–9 hours. For those who value time, the train is the best compromise between cost and speed.

The upshot

A traveler with more time than budget can score a bus ticket for the price of a dinner out. But a professional making a day trip will pay up to €200 round trip for the convenience of a flight or train — and the train still wins on downtown-to-downtown speed.

The pattern: the cheapest option is bus, but time constraints push travelers toward train or flight.

Is it quicker to fly or train from London to Paris?

Flight total travel time including airport transfers

A typical flight from a central London airport (Heathrow) requires: 30 minutes to the airport, 30–45 minutes check-in/security, 15 minutes boarding, 1h15min flight, 20 minutes taxi, 30 minutes baggage claim, plus another 30–60 minutes into central Paris. That adds up to 3.5–5 hours door-to-door.

Train city center to city center time

Eurostar (direct rail operator) quotes the fastest journey at 2 hours 16 minutes. Trainline (train booking platform) reports an average of 2 hours 31 minutes. Both are between St Pancras and Gare du Nord — two central stations — so no extra transfers.

3 data points, one verdict: the train is almost always faster when both city centers are the start and end points. Klook (travel booking blog) notes that even with perfect logistics, a flight takes 3–4 hours total, while the train is a consistent 2h20min. The only exception: if you live within walking distance of an airport and your destination is near a Paris airport, the flight can match the train’s door-to-door time.

Bottom line: For the vast majority of travelers starting or ending in central London or Paris, the train is the faster option. The flying time advantage is eaten up by airport logistics.

The implications: train wins on speed for central travelers.

What is the cost of the bullet train from London to Paris?

Eurostar ticket prices

Eurostar (direct rail operator) sells tickets from $52 (£42.50) one-way on its U.S. site. Trainline (train booking platform) lists advance fares from $73.29. Walk-up prices can exceed $200 in busy periods.

Factors affecting train cost

  • Time of booking: advance tickets are cheapest; same-day is priciest
  • Class of service: Standard from $52, Standard Premier (meal included), Business Premier (flexible) from $200+
  • Season: summer and holiday periods see higher demand and prices
  • Day of week: midweek is cheaper than Friday/Sunday

How to get cheap Eurostar tickets

Sign up for Eurostar’s newsletter, book 6–11 months ahead, and consider a Flexi fare if your plans might change. Comparison sites like Omio can also surface deals.

Bottom line: The train’s base price is competitive with flights, but its real value is the lack of hidden fees and the city-to-city speed. For organized travelers who plan ahead, it’s the most predictable option.
The catch

Last-minute Eurostar fares can double or triple, making a budget flight suddenly cheaper even after adding baggage and transfers. The trade-off is most acute for spontaneous travelers.

The catch: last-minute pricing can flip the cost advantage.
