Short answer: on the London to Paris route in 2026, the plane vs train choice comes down to two things. Eurostar wins on speed and simplicity — about 2 h 16 from city centre to city centre — while budget airlines now win on headline price, with easyJet fares from Southend to Paris from £68 against a cheapest next-day Eurostar fare of £196. The right answer depends on where you start and how far ahead you book.
The London–Paris corridor has become one of the most fiercely contested short-haul markets in Europe, and 2026 is the year the gap narrowed. Airlines have piled in with new routes and extra frequencies, betting they can tempt travellers away from rail. So when you weigh up London to Paris by plane vs train, what actually wins? Here is the honest comparison.
Why London to Paris is suddenly a price war
By spring 2026, aviation analysts expect more than 50 flights every day between the two capitals, spread across five London airports (Heathrow, Gatwick, Luton, Stansted and London City) and two Paris hubs (Charles de Gaulle and Orly). That sits on top of Eurostar's frequent high-speed service between St Pancras International and Gare du Nord.
Two launches tipped the balance. easyJet reinstated a Stansted–Paris Charles de Gaulle link on 5 March 2026, a seasonal route running mainly Mondays and Fridays through to October — its first service aimed squarely at northeast London and the East of England. Around the same time, Air France opened a Gatwick–Charles de Gaulle service on 29 March 2026, with two daily round-trips, taking on easyJet head-on. Together with existing flights from Heathrow, Luton, Southend and London City, the result is an unusually dense mesh of options.
The frequency gap is now real. Schedule filings suggest that on Fridays from April 2026, there will be around 27 flights each way between London and Paris, compared with about 18 Eurostar trains. For the first time in years, the plane is competing on choice of departure times, not just price.
Plane vs train: the price reality
This is where airlines land their punch. For a one-way trip the following day, the cheapest Eurostar deal was £196, while the cheapest easyJet flight from Southend to Paris CDG was £68 — barely one-third of the rail fare. easyJet markets lead-in fares on its London–Paris flights from around the mid-£30s, with sample one-ways reported between roughly €40 and €100 on popular spring and summer dates.
Eurostar can be cheap too, but mostly when you book early: advance fares fall well below £100, and the operator runs regular flash sales. The problem is last-minute and peak-date pricing, which is exactly where flights now undercut it. If you are price-sensitive and flexible on airport, the plane often wins the headline number — though baggage fees, seat selection and airport transfers can quietly erase the saving.
The catch with flights is the hidden time and cost. A £68 fare from Southend looks unbeatable until you add the rail or coach trip to the airport, the recommended two-hour check-in, security, and the transfer from CDG into central Paris on the RER B. Door to door, the "cheap" flight can take longer and cost more than the train.
Plane vs train: speed and convenience
Here Eurostar is hard to beat. The journey from London St Pancras to Paris Gare du Nord takes about 2 h 16, and both stations sit in the heart of their cities. There is no airport transfer at either end, security is quick, and the baggage allowance is generous compared with a budget airline's strict hand-luggage limits.
That is why, despite all the new flights, Eurostar is still expected to keep the majority share of point-to-point traffic between the two cities. Its appeal is the whole door-to-door experience: walk into a central station, board with minimal fuss, and step off in the middle of Paris ready to start your day. For more on check-in times, luggage rules and on-board classes, our Eurostar travel guide covers the details.
The numbers back the demand. Eurostar carried 19.5 million passengers in 2024, up 5% year on year, and is targeting 30 million a year. It runs the largest international high-speed network in Western Europe, serving 28 destinations — momentum that explains why airlines see the route as worth fighting for.
How to choose — and book smart
The truth is that "plane vs train" is no longer a fixed answer; it depends on your trip. A few rules of thumb:
- Live near Stansted, Luton or Southend? A budget flight may genuinely be cheaper and not much slower door to door.
- Travelling from central London, or carrying luggage? Eurostar's city-centre speed and baggage allowance usually win.
- Booking last minute on a peak date? Compare both — this is when flights most often undercut rail.
- Booking weeks ahead? Eurostar advance fares are frequently the best total value once airport costs are added.
The smartest move is to compare every option on the same screen rather than assuming.

In short
- More than 50 flights a day now link London and Paris in 2026, across five London airports and two Paris hubs.
- easyJet added Stansted–CDG (5 March 2026) and Air France added Gatwick–CDG (29 March 2026), intensifying the price war.
- On Fridays from April, around 27 flights each way run versus 18 Eurostar trains.
- Cheapest next-day fares: £196 by Eurostar vs £68 by easyJet from Southend — but airport time and transfers narrow the real gap.
- Eurostar wins on speed (~2 h 16, city centre to city centre) and is still expected to keep most of the traffic.
- Best tactic: compare plane and train together, and book early for the lowest total cost.
Frequently asked questions
Is it cheaper to fly or take the train from London to Paris?

How long does Eurostar take from London to Paris?
About 2 h 16 from London St Pancras to Paris Gare du Nord, city centre to city centre, with no airport transfer at either end.

Which is faster door to door, plane or train?
For most central-London travellers, the train. A flight's two-hour check-in, security and transfers from Charles de Gaulle into Paris usually make the total journey longer than Eurostar's 2 h 16, even though the flying time is shorter.
