Getting Out of London: How to Travel Internationally

London is one of the best-connected cities on earth. Multiple major airports, direct trains into Europe, and enough departure options to get you almost anywhere on the continent for less money than a dinner out. The trick is knowing which option actually makes sense for your trip, because the cheapest flight is not always the cheapest journey.

The Airports: Know Which Is Which

London has six airports. They are not equal, and the one you use matters.

Heathrow is the big one. Long-haul flights to North America, Asia, the Middle East, Africa, and the rest of the world. If you’re leaving Europe entirely, you’re almost certainly going through Heathrow. It’s a large, efficient airport and getting there from central London is straightforward: the Elizabeth line connects Heathrow to central London in around 40 minutes, with fares from £13.90. The Piccadilly line is cheaper at around £5.50 with contactless but takes closer to an hour.

Gatwick is where you want to be for most mid-range and full-service European routes. British Airways, easyJet, Norwegian, and a range of others fly from here. The Southern or Thameslink train from London Bridge, Victoria, or Farringdon gets you there in around 30 minutes and the off-peak contactless fare is £10.70. That’s it. No coach, no faff, no 90-minute journey to the back of beyond. You tap your bank card at the barrier and get on a train. Gatwick is the most painless of London’s airports and is genuinely underrated as a result.

Skip the Gatwick Express. It costs £24.10 single versus the £10.70 contactless fare on Southern or Thameslink, saves about five minutes, and is not worth the difference under any circumstances.

Stansted is Ryanair’s main London base, along with other ultra-budget carriers. Flights are cheap. Getting there is less so, or at least less convenient. Stansted is in Essex, significantly further from the city centre than Gatwick or Heathrow.

Your two main options:

National Express coaches run from multiple points across London from £9.50 one-way, booked in advance (typically more like £13 one way), and take around 45 minutes to 1.5 hours depending on traffic and where you get on. Book the return at the same time and it’s cheaper still. Flix bus is also another similarly priced alternative.

The Stansted Express train from Liverpool Street takes 48 minutes and typically costs £23 one way. Faster than the coach, but Liverpool Street is not central for everyone and the fare goes up sharply if you don’t book in advance.

Either way, factor the transfer into your journey time calculation before getting excited about that £19 flight. Remember you may also need some sort of transport to get to the National Express bus stop or the Stansted Express train station.

Luton is the fourth option and the most awkward to get to, which is worth knowing before you book anything flying out of it. It’s around 48km from central London, used mainly by easyJet, Wizz Air, Ryanair, and TUI for European and some North African routes.

The train is the fastest option in theory. Thameslink runs from St Pancras International to Luton Airport Parkway in around 20 to 50 minutes depending on the service. The catch: you can’t walk from the train station to the terminal. The Luton DART, an automated transit system, connects Luton Airport Parkway to the terminal in under four minutes and costs extra on top of your train fare. It’s not a dealbreaker but it is an additional step and an additional cost that people don’t always spot when they’re comparing options.

National Express coaches run from London Victoria to Luton Airport up to 47 times daily from £7.50 one-way, with the fastest journeys taking around 40 minutes. For many people coming from south or west London, the coach is actually more convenient than the train given it drops you at the terminal directly.

Luton is fine. It’s just worth going in with eyes open about the transfer, and giving yourself the same time buffer you’d give Stansted.

London City Airport is the one most visitors overlook, and for some trips it’s the smartest choice. It sits just 11km from the city centre, and the DLR gets you to Liverpool Street in around 20 minutes. The downside is limited routes. Airlines operating here include British Airways, Aer Lingus, and KLM, covering European business routes rather than the full budget spectrum. If your destination happens to be served from City, the transfer alone makes it worth considering over any other London airport.

Southend is a small airport in Essex, further out than Stansted, with limited routes. Unless you’ve specifically found a flight from there that works, it’s not worth factoring into most itineraries.

The Real Cost of Flying from Stansted or Luton

This is the part people don’t think about until they’re living it.

You need to be at Stansted at least 90 minutes before departure. Budget airlines run through some of the busiest terminals in the country and security queues can get genuinely unpleasant. Miss the flight and the next available fare is rarely the same price as the one you just lost.

In practice: the flight rarely takes off on time. Budget carriers run tight turnarounds and any delay compounds along the day. Expect 30 minutes late on average, often more.

When you land: getting through customs and into the city centre at your destination typically adds another 90 minutes, sometimes more depending on passport control queues.

Add it all up. A “cheap” morning flight from Stansted to Rome:

• Leave home 5am to reach Stansted by 7am
• Board at 8:30am, take off closer to 9am
• Land, clear customs, reach central Rome: 2pm

That’s nine hours door to city centre. And you’ll do the same in reverse on the way home. On a short trip, that’s nearly a full day of your time gone on logistics.

Driving and the Ferry: The Full Picture

Taking your own car into Europe is an option, and for some trips it makes sense, particularly if you’re travelling with a group, carrying a lot of kit, or planning to drive around once you arrive. But go in with a clear-eyed view of what it actually involves.

The drive from London to Dover takes around two hours via the M25, M2, and A2. Dover itself is fine. The port is straightforward to navigate, there are regular sailings, and the crossing itself is short. DFDS operates up to 30 daily sailings from Dover to Calais in around 100 minutes, with fares from £99 for a car and up to four passengers one-way. Booked well in advance and split across a group, that’s reasonable value.

Typical prices range from around £82 to £160 one-way depending on the season and how far in advance you book. Peak season and leaving it late will push you well above that.

Once you’re through Calais and onto French roads, here’s the honest truth: the drive through northern France is not exciting. It is flat, agricultural, and largely motorway. You’ve spent the best part of half a day getting to the coast, crossed a body of water, and now you’re driving through rural France on the A26 looking at fields. If your destination is Paris or further south, you’re looking at several more hours of motorway. It gets more interesting eventually. It takes a while.

Check-in at Dover closes 60 minutes before departure for passengers with a vehicle, and in busy season the advice is to arrive at least two hours before sailing. Factor that into your 5am departure calculation.

For the trip to make sense, you either need the freedom of having a car at your destination, a group large enough to make the ferry cost per head worthwhile, or a specific route that doesn’t work well by public transport. As a solo traveller heading to a major European city, the train is almost always faster, simpler, and less exhausting.

The Train to Europe: Faster Than It Looks

The Eurostar departs from St Pancras International, right in central London, and takes around two and a half hours to Paris and two hours to Brussels. Amsterdam takes just over four hours direct. Other destinations include Lille, Rotterdam, and Cologne, with seasonal services to ski resorts in the French Alps.

The key difference from flying: customs and passport control are handled at St Pancras before you board, so when you arrive in Paris or Brussels you walk straight out of the station and into the city. No 90-minute transfer from an airport on the outskirts. You board in central London and step off in the centre of Paris. That time difference matters more than the headline journey time suggests.

On price: booking 30 days in advance typically costs around £100 return to Paris, while leaving it to 7 days out can push that to over £200. Tickets open up 10 to 11 months in advance, and the cheapest fares go early. Book as soon as you know your dates.

The train will often cost more than a budget flight on paper. Factor in airport transfers, baggage fees, security time, and the transfer to the city centre on arrival, and the gap closes significantly. For Paris, Brussels, or Amsterdam, the train is the better journey almost every time.

Coach Travel: The Budget Option

If you want to cross into Europe on the absolute minimum budget and time is flexible, coach travel is worth knowing about. Flixbus and Eurolines operate services from London Victoria to Paris, Brussels, and Amsterdam, with tickets often available from £15 to £25 one-way booked in advance.

The trade-off is time. London to Paris by coach takes around seven to eight hours depending on the crossing and border delays. You’ll sit on a ferry for 90 minutes in the middle, cross through northern France, and arrive considerably more crumpled than you left. It’s fine for an overnight journey where you sleep through the dull bits. For a daytime trip, the Eurostar wins without much argument.

Book Smart

A few rules that apply across everything:

Book directly with the airline or train operator. If anything goes wrong, a rebooking or cancellation is handled directly between you and the provider. Third-party booking sites add a layer of complexity that helps no one when things go sideways.

For train tickets to Gatwick or any UK rail journey, Trainpal is worth using. It splits tickets in ways the main booking sites don’t always surface, which can cut the price meaningfully. With a railcard the savings compound further.

Book early. The price difference between booking a Eurostar six weeks out and booking it two weeks out can be £100 or more. Budget airline fares follow the same pattern. The seat exists. It just costs considerably more the closer you leave it.
