London to Edinburgh is one of the busiest domestic routes in the UK, and you can do it by air or by rail. Flying is quicker in the air but not always door to door, while the train takes longer but runs from city centre to city centre. This guide compares the two on speed, cost, airports and environmental impact so you can choose what fits your trip. Fares and timetables change constantly, so check live prices for your dates.
Which is quicker, flying or the train?
A flight is usually around an hour and a half in the air, while the train is several hours. But the comparison is not that simple. For a flight you must travel to the airport, arrive in good time for security, collect baggage and then travel into the city at the other end. For the train you normally travel to the station, board and arrive in the centre of Edinburgh. Once those extras are counted, the gap narrows, and for some journeys the train is competitive.
- Count travel time to and from each airport or station, not just the journey itself.
- Allow for security and boarding time on flights.
- Remember that trains can be affected by engineering works or delays, as can flights.
- Check the running time for your specific departure.
Which is cheaper?
It depends on when you book and how flexible you are. Advance rail fares can be good value if you book early and choose off-peak times, while last-minute rail tickets can be expensive. Low-cost flights can look cheap, but bags, seat selection and airport transfers can add up. Always compare the total cost of the journey, not just the headline fare. Our cheap holidays guide includes general tips on comparing costs, and our hand luggage guide explains how baggage rules can change the price.
- Book as early as you can for the widest choice.
- Be flexible on time and day to find lower fares.
- Check cancellation and change rules.
- Add up extras such as luggage, transfers and food.
- Consider split tickets on rail only if the terms are clear.
Which airport should I use?
London has several airports, and the best one depends on where you live and which airlines fly the route. Many travellers from the South East compare Gatwick with other options, since it is accessible by train from Sussex. Our holidays from Gatwick page and train comparison explain the practical side. Check which airports have direct flights to Edinburgh on your dates, because routes and schedules change.
On the Edinburgh side, the airport is outside the city centre, so allow time and budget for a tram, bus or taxi into town. If you are bringing a lot of luggage, factor that in.
What about the carbon footprint?
As a general principle, rail travel tends to produce lower emissions per passenger than short-haul flying on the same route, though exact figures depend on the train, the aircraft and how full each one is. If environmental impact matters to you, look at the operators own published figures and independent comparisons rather than relying on a single number. We do not quote figures here because they vary between sources and over time.
Which is better for different kinds of traveller?
Business travellers
Many value the train for the ability to work on board and arrive in the city centre. Others prefer the speed of a flight when they are tight on time.
Families
Trains give more room to move around and fewer luggage restrictions, which many parents like. Flights can be quicker but involve more queues and rules.
Budget travellers
Compare both carefully. Advance rail fares or low-cost flights can each win depending on the date.
Weekend breakers
If you only have two nights, the time you save by flying may matter. See our weekend breaks from Brighton ideas for other short trips.
Planning your Edinburgh trip
Edinburgh is compact and walkable, with a historic old town, a castle, museums and plenty of places to eat. It gets busy in August and around Christmas and Hogmanay, so book accommodation early for those periods. Check opening times and ticket rules for attractions on their official sites. Our Edinburgh Christmas markets guide covers the winter season.
- Arrange travel insurance if you have non-refundable bookings.
- Consider a hire car only if you plan to leave the city.
- Pack for changeable weather.
- Check baggage rules before you fly.
How to decide in five minutes
If you are short of time, a quick checklist can settle the question. Look at your actual starting point, because living near a good airport or a mainline station changes the answer. Then compare the total cost, the door-to-door time and how much luggage you are bringing. Finally, think about how you want to feel on arrival, since many people find the train more relaxing and a flight more efficient.
- Starting point: which is easier to reach, an airport or a mainline station?
- Luggage: a large case suits the train, while a cabin bag suits a budget flight.
- Time: add transfers, security and boarding to the flight time.
- Cost: include bags, seat fees and transfers on both sides.
- Flexibility: check the change and refund terms on each ticket.
- Comfort: think about whether you want to work, sleep or sightsee on the way.
Tips for getting a better price
Prices for both modes change with demand, so the same trip can cost very different amounts depending on the day. Booking early often helps, and travelling at less popular times can bring the fare down. Be wary of third-party sellers with unclear terms, and compare with the operator own website before paying. Rail fares in particular can differ depending on the ticket type, so read the conditions on time restrictions and changes.
- Set a price alert if the booking tool offers one.
- Compare nearby airports or stations.
- Check whether a railcard or other discount applies to you.
- Avoid peak travel days if you can.
- Read the baggage terms before choosing a low-cost flight.
Accessibility and comfort
Both options offer assistance for disabled travellers, but you usually need to arrange it in advance. Trains typically provide step-free access at major stations and space for wheelchairs, while airports offer special assistance from check-in to boarding. Contact the operator ahead of travel and ask for details specific to your needs. If you are travelling with young children, consider the time you will spend queuing, since this can influence which option feels easier overall.
What to expect on the day
On a flight day, plan to be at the airport comfortably ahead of departure, keep liquids and electronics easy to reach for security and check your baggage allowance one last time. On a train day, arrive at the station in good time, check the departure board for your platform and find your reserved seat if you have one. In both cases, a charged phone with your tickets saved offline is a simple way to avoid stress.
Delays can happen on either mode, so do not book a tight connection straight after arrival, such as a timed attraction or a restaurant reservation, unless you have built in a buffer. If you are travelling for a business meeting, aim to arrive the evening before. Our city breaks hub has more ideas for planning short trips around the UK and Europe.
Packing and travelling light on either option
Your luggage can tip the balance between the two. On the train you can usually carry larger bags without extra fees, and you do not need to measure them against a cabin limit. On a flight, a small cabin bag can keep costs down, but checked bags and sports equipment add to the price. Think about what you are taking, and whether you would rather avoid baggage rules altogether. Whichever you choose, keep your tickets, a charger and a drink easy to reach.
Making a longer weekend of it
If you are heading north for leisure, the journey is part of the trip. A daytime train gives you scenery and time to relax, while an early flight can give you a longer day in the city. Browse our city breaks and UK holidays guides for ideas on how to build a trip around your travel choice.
