Train vs Flight Guide

What should I know about The Door-to-Door Reality?

Flight schedules are deceptive — the airtime is just part of the journey. True door-to-door time: arrive airport 2 hours early (international), 1.5 hours (domestic). 30-60 minutes getting to airport (often further from city centre than train stations). Security: 20-45 minutes. Boarding: 20-30 minutes. Disembark and exit airport: 30-60 minutes (plus passport control for non-Schengen). Transfer from airport to city centre: 30-90 minutes. Total overhead: typically 3-4 hours each way for short-haul flights once all the airport and transfer time is added, which is why trains often win on total door-to-door time for shorter routes despite a slower cruising speed.

What should I know about Hidden Costs of Flying?

The headline flight price often excludes: checked luggage: £15-50 per bag per flight (return). Allocated seating: £5-30 per person per flight. Airport parking or transfers (often more expensive than city centre stations). Airport food and drinks (2-4× city prices). Priority boarding if relevant. Travel insurance excess for delays. Carbon offset (optional). Duty free temptation. These can add £50-200 per person to the headline flight cost for a return trip. Train advantages: usually city centre to city centre travel, with no equivalent hidden add-on costs beyond the ticket price itself.

What do I need to know about Carbon Footprint Comparison?

The carbon difference is dramatic for European routes: London-Paris by Eurostar: approximately 6kg CO₂ per person return. London-Paris by flight: approximately 120-150kg CO₂ per person return (including radiative forcing). The Eurostar is 20-25× lower carbon. This is because: Eurostar runs on electricity (largely low-carbon French nuclear power). The journey is so short that most aviation emissions occur at high altitude (where radiative forcing multiplies the warming effect). London-Edinburgh comparisons consistently show the train producing a small fraction of the emissions of the equivalent short-haul flight, making it one of the clearest examples of the rail advantage on carbon grounds.

When Flying Makes Sense?

Train usually wins (time and/or cost) for: London-Paris, London-Brussels, London-Amsterdam (Eurostar). London-Edinburgh, London-Manchester, London-Glasgow (LNER/Avanti). Most intra-UK routes under 400km. Flight usually wins for: routes without direct rail links requiring changes. Very long European routes (London-Rome, London-Barcelona: 10-24 hours by train vs 2.5h flight). Routes crossing sea without tunnel. When connections would require overnight stays. Compromise: overnight sleeper trains — combining the journey with the night's accommodation, so the travel time doesn't feel like time lost from the trip itself.
