The fastest airport train is not always the best choice—and a train with “Express” in its name is not automatically worth paying extra for.

The cheapest London airport transfer depends on where you are staying. A direct train to the station nearest your accommodation may save more time and money than the service with the shortest advertised journey.

This guide compares the practical routes from London’s main airports, including when you can use contactless and how new Rakuten members may be able to receive £25 back after an eligible train purchase.

Luton Advance coach or Thameslink Luton Airport Express and DART St Pancras, Farringdon, Blackfriars, London Bridge
London City DLR The normal DLR route is already fast Canning Town, Canary Wharf, Stratford and Bank connections
Southend Advance Greater Anglia train The same direct train Stratford and Liverpool Street

Before choosing an airport transfer

Check these four things:

  1. Your arrival terminal: Heathrow has several rail stations, while Gatwick’s station is at the South Terminal.
  2. Your final destination: Paddington is useful for some hotels but inconvenient for others.
  3. Your arrival time: Passport control and baggage collection make flight arrival times unreliable.
  4. Every passenger’s ticket: Each traveller using contactless must have their own card or device.

Use Citymapper or a National Rail journey planner after landing to check disruption and the next practical departure.

Our guide to Oyster, contactless and London travel caps explains how to pay once you reach the London transport network.

1. Heathrow Airport: Piccadilly versus Elizabeth line

Heathrow has three direct rail options into London.

Cheapest: Piccadilly line

The Piccadilly line is normally the cheapest rail route between Heathrow and central London. It serves Terminals 2 and 3, Terminal 4 and Terminal 5.

The journey generally takes around 50–60 minutes, but it can be particularly convenient for accommodation near Earl’s Court, South Kensington, Green Park, Piccadilly Circus, Leicester Square or King’s Cross St Pancras.

You can pay with Oyster or contactless. The fare contributes towards the relevant TfL daily cap.

Best balance: Elizabeth line

The Elizabeth line is faster and more spacious than the Tube. It serves Paddington, Bond Street, Tottenham Court Road, Farringdon and Liverpool Street, with journeys into central London taking less than 40 minutes.

Oyster and contactless are accepted. Heathrow Elizabeth line journeys have special airport fares, so do not assume the price is the same as an ordinary Zone 6 Tube journey.

For many visitors, this is the best balance between speed, comfort and price.

Fastest to Paddington: Heathrow Express

Heathrow Express takes approximately 15 minutes between Terminals 2 and 3 and London Paddington. Terminal 5 takes a few minutes longer.

Advance single tickets can start from £10 when purchased at least 30 days ahead. Flexible or last-minute fares can be considerably more expensive. Children aged 15 or under can travel free in Standard Class with a paying adult under the operator’s current conditions.

Do not buy Heathrow Express automatically if you must then cross London from Paddington. The Elizabeth or Piccadilly line may provide a simpler complete journey.

2. Gatwick Airport: compare the destination

Gatwick’s station is connected to the South Terminal. A free airport shuttle links the North and South terminals. Trains to London generally take around 30–45 minutes.

Thameslink serves London Bridge, Blackfriars, City Thameslink, Farringdon and St Pancras International. It is often the most convenient choice for the City, King’s Cross, north London or an Elizabeth line connection at Farringdon.

Southern

Southern trains run to London Victoria, normally calling at East Croydon and Clapham Junction. A Southern service can be cheaper than Gatwick Express while reaching the same terminus.

Gatwick Express

Gatwick Express provides a direct service to Victoria. It can be convenient, but it is not automatically the cheapest train to Victoria. Compare it with Southern before paying.

Oyster and contactless pay as you go are accepted between Gatwick and London on participating rail services. Contactless is convenient, but Advance tickets, GroupSave, Railcard fares or a return ticket may cost less.

Get £25 back on a qualifying train purchase

New Rakuten members may currently receive a £25 referral reward after completing at least £50 of eligible shopping through Rakuten within 90 days.

This can be useful for a family or return airport train booking through a participating retailer such as Trainline—but only if that retailer and ticket category are eligible when you book.

This is not an immediate ticket discount. You pay the full price first. After the purchase tracks and the retailer approves it, Rakuten pays the eligible reward later, including through PayPal where available.

How to use the offer

  1. Join Rakuten through our referral link.
  2. Confirm that the joining page shows the £25 reward and £50 requirement.
  3. Search for Trainline or another eligible train retailer inside Rakuten.
  4. Read the retailer’s exclusions before clicking through.
  5. Complete the purchase in the same browser session.
  6. Avoid unlisted voucher codes and other cashback extensions.
  7. Keep the booking confirmation until the transaction and reward are approved.

The qualifying amount, participating retailers and referral reward can change. Treat the later payment as pending rather than guaranteed.

Referral disclosure: London for Cheap may receive a reward if you join through our link and complete the current requirements. Your reward is not reduced.

3. Stansted Airport: coach versus train

Stansted is outside the standard London fare zones.

Cheapest: advance coach

National Express and other coach operators connect Stansted with several London stops. Advance fares can start from approximately £5, although the cheapest tickets are limited.

Coaches operate throughout the night and stop directly outside the terminal. They can be useful for very late arrivals, early departures or accommodation near a coach stop. The disadvantage is London traffic, so allow considerably more time when travelling to the airport.

Our National Express new-customer discount guide explains the current offer. Compare the discounted fare with the train before booking.

Fastest: Stansted Express

Stansted Express runs to Tottenham Hale in approximately 37 minutes, Liverpool Street in approximately 48 minutes and Stratford in around one hour.

Tottenham Hale is useful for the Victoria line. Liverpool Street connects with the Central, Elizabeth, Circle, Metropolitan and Hammersmith & City lines.

Contactless payment is now accepted on Stansted Express. Oyster cards are not valid to or from Stansted Airport. Advance tickets may cost less than tapping contactless, so compare both.

4. Luton Airport: remember the DART

The railway station is called Luton Airport Parkway. It is not beside the terminal. The Luton DART automated shuttle connects the terminal and station in around four minutes.

Thameslink runs directly to St Pancras International, Farringdon, City Thameslink, Blackfriars and London Bridge. It is usually the most flexible rail option and some services operate through the night.

Luton Airport Express

East Midlands Railway operates faster trains between Luton Airport Parkway and St Pancras. The quickest rail-and-DART journey can take approximately 32 minutes from the terminal to St Pancras.

Buy the correct ticket

Use Luton Airport as the origin or destination if you want the DART included. A ticket only to Luton Airport Parkway may leave you needing to pay separately for the terminal connection.

Contactless payment is available for the journey, including the DART, but Advance rail tickets can sometimes cost less.

Coaches stop outside the terminal. A coach can be cheaper and avoids the DART transfer, but road traffic makes the journey less predictable.

5. London City Airport: use the DLR

London City is the easiest major London airport to reach by ordinary public transport.

Its DLR station is in Zone 3, with connections at Canning Town, Poplar, Stratford, Bank and Tower Gateway.

Use Oyster or contactless and touch in and out as you would for another London rail journey. The fare contributes towards the relevant daily cap.

6. Southend Airport: take the direct train

Greater Anglia trains connect Southend Airport with Stratford and London Liverpool Street. The airport station is a short walk from the terminal, and the journey to Liverpool Street normally takes around 45–55 minutes.

Southend is outside the London fare zones. Buy a valid National Rail ticket and compare Advance, Railcard and group fares.

Stratford may be the better interchange for east London, Canary Wharf or the Elizabeth and Jubilee lines. Liverpool Street is more useful for the City and onward central London connections.

When is a taxi worth it?

Public transport is normally cheaper for one or two adults, but a licensed taxi or pre-booked car may become reasonable when:

  • Four or more people share the fare.
  • You have several large suitcases.
  • Your accommodation is poorly connected.
  • You are travelling with small children late at night.
  • A disability or mobility requirement makes several changes difficult.
  • Rail engineering work affects the route.

Compare the complete door-to-door cost. Never accept an unsolicited ride from someone approaching passengers inside the terminal.

Late-night airport arrivals

Do not assume every rail service operates throughout the night.

  • Heathrow: The Piccadilly Night Tube operates on Friday and Saturday nights. The N9 night bus provides another overnight route.
  • Gatwick: Some Thameslink services operate overnight, but frequency varies.
  • Stansted: Coaches operate 24 hours and can be more useful after the final train.
  • Luton: Some Thameslink trains and airport coaches operate overnight.
  • London City and Southend: Check the final DLR or Greater Anglia departure.

Search using your expected station departure time—not the scheduled flight arrival. Allow for passport control, baggage collection and the journey from the terminal to the station.

Airport-transfer mistakes that cost money

Buying the express train without checking your hotel

A 15-minute journey to Paddington is not especially fast if your accommodation then requires two more trains.

Searching only for “central London”

Search for your hotel or nearest station instead.

Buying a Luton Parkway-only ticket

Make sure the fare includes the DART if you need to reach the terminal.

Assuming Oyster works at every airport

Oyster is not valid to Stansted, Luton or Southend. Contactless coverage is wider, but fare rules vary.

Using one contactless card for two adults

Every passenger aged 11 or over needs their own card, device, Oyster card or ticket.

Mixing a bank card and mobile wallet

Touching in with a physical card and out with the same card on your phone creates two incomplete journeys.

Chasing cashback instead of the lowest fare

A pending £25 reward is useful only when the underlying ticket is competitive and the purchase satisfies every condition.

Which transfer should you choose?

Choose the Piccadilly line from Heathrow when price matters most.

Choose the Elizabeth line from Heathrow for a faster, more comfortable journey to the West End, City or east London.

Choose Southern or Thameslink from Gatwick according to the station closest to your accommodation.

Choose an advance coach from Stansted or Luton for the lowest possible fare, particularly overnight.

Choose the Stansted Express or Luton rail connection when predictable journey time matters more.

Choose the DLR from London City Airport in almost every ordinary situation.

Before paying, compare the complete route, ticket restrictions and arrival station. The cheapest airport train is only a bargain when it takes you somewhere useful.
