The True Door-to-Door Time
Flight times are deceptive. A Paris–London 'flight' of 1h 15m requires arriving 90 minutes early, taking the Tube to Heathrow (45-60 min), clearing security (30 min), then landing at Gatwick and reaching central London (50 min). Total: 4h 30m minimum. The Eurostar from Paris Gare du Nord to London St Pancras takes 2h 16m door-to-door with 30 minutes check-in. Train wins by over 2 hours.
Route-by-Route Comparison
Paris–London: Train (Eurostar 2h16m) vs Flight (4h30m door-to-door) — Train wins. Paris–Brussels: Train (Thalys/Eurostar 1h22m) vs Flight (4h+) — Train wins. Paris–Amsterdam: Train (Thalys 3h20m) vs Flight (4h door-to-door) — Train wins. Berlin–Munich: Train (ICE 4h) vs Flight (3h30m door-to-door) — Flight slightly faster. Madrid–Barcelona: Train (AVE 2h30m) vs Flight (3h45m door-to-door) — Train wins. Above 700 km, flying usually wins on time.
Carbon Footprint
A Paris–London flight emits approximately 54 kg CO2 per passenger (Economy). The Eurostar emits just 4 kg CO2 — 93% less. For Paris–Amsterdam, the Thalys emits 2 kg vs 65 kg for a flight. The EU's 'Fit for 55' initiative has prompted France to ban short-haul flights where a train under 2.5h exists — similar laws are under discussion in Germany, Austria, and Belgium. Choosing the train for sub-700 km journeys makes a measurable environmental difference.
Cost Comparison
Budget airlines appear cheaper but add checked baggage (€25-50 each way), transport to/from airports, and sometimes hidden fees. A Ryanair Madrid–Barcelona flight listed at €25 often costs €80+ with one bag. The AVE Promo fare is €14-35 and includes 2 bags free, city-centre-to-city-centre. For 2 travellers, train tickets bought 6 weeks ahead are usually comparable to or cheaper than budget air tickets, especially when factoring in baggage.
Frequently Asked Questions
Is the train always slower than a plane for long distances?
For routes over 700 km (e.g., London–Madrid, Paris–Rome), flights are usually faster door-to-door. Under 500 km, trains win almost every time.
Which European routes have banned short-haul flights?
France banned domestic flights where a train under 2.5h exists (Paris–Lyon, Paris–Bordeaux, Paris–Nantes). Similar rules are being introduced in Germany and Belgium.
