Quick Answer
The best overall way from Luton Airport (LTN) to Heathrow Airport (LHR) for most travelers is a combination of the Luton Airport Express train to central London, followed by the Elizabeth Line (Tube) direct to Heathrow. This balances speed, cost, and reliability. The cheapest way is the direct National Express coach. For the fastest door-to-door time with heavy luggage, a pre-booked private transfer is superior. Total journey time ranges from 1h 15m to over 2 hours, with costs from £10 to £150+.
By Train: The Step-by-Step Guide
Traveling by train is the most frequent and often the fastest public transport option, but it involves a multi-leg journey. There are two main rail routes, each with a critical initial step: getting from Luton Airport Terminal to Luton Airport Parkway station via a short shuttle bus.
| Route Option | Key Steps | Approx. Total Time | Advantage |
|---|---|---|---|
| Via London St Pancras (Recommended) | 1. Shuttle to Parkway 2. Luton Airport Express to St Pancras (22 mins) 3. Tube (Piccadilly/Elizabeth Line) to Heathrow |
1h 30m - 1h 50m | Fastest train leg, excellent central London connections. |
| Via Thameslink (Budget) | 1. Shuttle to Parkway 2. Thameslink train to Farringdon/Blackfriars (45-55 mins) 3. Elizabeth Line to Heathrow |
1h 45m - 2h 10m | Often cheaper, Oyster/Contactless accepted on train leg. |
The Essential Shuttle Bus
Before any train, you must take the DART (Direct Air-Rail Transit) from directly outside the terminal to Luton Airport Parkway station. The journey takes about 4 minutes. Tickets are usually included in your train ticket if purchased to/from "Luton Airport". If bought separately, it costs approx. £5.
Deep Dive: The Elizabeth Line vs. Piccadilly Line to Heathrow
From central London, you have two direct Tube options to Heathrow:
- Elizabeth Line: Faster (approx. 30 mins from Paddington), newer trains with dedicated luggage space, and air conditioning. Slightly more expensive than the Piccadilly Line.
- Piccadilly Line: Slightly cheaper, but slower (approx. 50 mins from central London), with older trains and less luggage space. It's a good budget backup.
By Coach/Bus: The Most Economical Choice
For budget-conscious travelers, direct coaches are the best value, eliminating stressful London train station changes.
National Express (The Primary Operator)
National Express runs frequent, direct services between LTN and LHR. Coaches are comfortable with amenities like free Wi-Fi, power sockets, and air conditioning.
- Journey Time: 1 hour 15 minutes to 1 hour 45 minutes (highly traffic-dependent).
- Frequency: Up to every 30 minutes during peak times.
- Cost: From £10-£15 one-way if booked online in advance. On-the-day fares can be significantly higher.
- Luggage: One large suitcase (20kg) and one carry-on included. Check allowances before travel.
- Pick-up/Drop-off: At Luton Airport's Coach Station (a 5-minute walk from the terminal) and directly at all Heathrow terminals.
Green Line Service 757 (An Alternative)
This service is less frequent but can be cheaper, especially for last-minute travel. It runs between Luton Airport and Heathrow Central Bus Station, stopping at several points in West London. Travel time is longer, often over 2 hours. It's useful if your schedule aligns, but National Express is generally more reliable for airport transfers.
By Taxi & Private Transfer: Door-to-Door Convenience
This is the most expensive but also the most convenient and stress-free option, especially for families, groups, or those with lots of luggage.
Pre-Booked Private Transfer (Highly Recommended)
Booking a fixed-price transfer in advance is safer and often cheaper than finding a taxi on arrival. Your driver will meet you in the arrivals hall with a name sign.
- Cost: £80 - £120 for a standard saloon car. Minivans for groups cost £100 - £150+.
- Journey Time: 45 minutes to 1 hour 30 minutes, depending on M1/M25 motorway traffic.
- Best For: Groups of 3+, families with young children, travelers with mobility issues, or those arriving on a late-night flight.
- Reliability: Flight monitoring is often included, so the driver adjusts for delays.
Black Taxis & On-Demand Minicabs
London Black Cabs are available at the taxi rank but will be extremely expensive for this cross-city journey (likely £150+). Local Luton minicab firms can be hailed or called, but always agree on a fare beforehand. Using a licensed, pre-booked service is strongly advised for transparency and safety.

Traveler Experience & Insider Tips
Managing Luggage
The train/Tube route involves lifts and long walks (e.g., at St Pancras). If you have more than one large case per person, seriously consider the direct coach or a private transfer. Some travelers use luggage forwarding services like Send My Bag for complete freedom.
Timing is Everything
Avoid Peak Hours: Weekdays 7-9:30 AM and 4-7 PM will see the worst traffic (affecting coaches/taxis) and crowded trains/tubes. Midday travel is smoothest.
Navigation in Stations
London stations are large. Look for signs for the Elizabeth Line (purple) or Piccadilly Line (dark blue). Allow an extra 10-15 minutes for transfers, especially during your first visit.
Contingency Planning
If your flight into Luton is delayed, a pre-booked train ticket may become invalid. Flexible train tickets cost more. For tight connections, a coach or transfer with more frequent services/forgiveness for delays is safer. Always have the TfL Go app or Citymapper app downloaded for live London transport updates.
FAQs: Luton Airport to Heathrow Airport Transfers
Is there a direct train from Luton Airport to Heathrow Airport?
No, there is no direct train service. The journey requires at least one change, typically at London St Pancras International (for the Luton Airport Express) followed by the London Underground (Tube) or the Elizabeth Line to Heathrow.
What is the cheapest way to get from Luton to Heathrow?
The National Express coach is consistently the cheapest option, with advance fares starting from £10-£15. The journey takes about 1 hour 15 minutes to 1 hour 45 minutes, depending on traffic.
How long does the fastest transfer take?
The fastest public transport option is a combination of the Luton Airport Express train (22 mins to St Pancras) and the Heathrow Express train (15 mins from Paddington). The total door-to-door travel time, including transfers and waits, is approximately 1 hour 30 minutes.
I arrive late at night. What are my options?
After about midnight, scheduled public transport options become very limited. Your main choices are a pre-booked licensed minicab or a taxi. National Express has some late services, but check schedules carefully.
Is it easy to travel with a lot of luggage?
Train and Tube transfers with multiple large bags can be challenging due to stairs and crowds. For heavy luggage, a direct National Express coach (luggage allowance applies) or a pre-booked private transfer is highly recommended for convenience.
Can I use my Oyster or Contactless card for the whole journey?
Not for the entire journey. You can use contactless/Oyster on Thameslink trains from Luton Airport Parkway and on London Underground/Elizabeth Line services. However, you must buy a separate ticket for the Luton Airport Express shuttle bus and the train from the airport parkway station.
Which option is best for a family or group?
For groups of 3 or more, a pre-booked private minivan transfer often becomes cost-competitive with buying multiple train tickets. It offers door-to-door service, fixed pricing, and handles luggage easily, reducing stress.
Should I book my transfer in advance?
Yes, it's strongly advised. Booking train tickets in advance can save money. Coach (National Express) tickets are cheaper when booked online. Private transfers and taxis guarantee availability and a fixed rate, especially important during peak hours or for late-night arrivals.
