Quick Answer
For most travellers, the fastest and most reliable way from Luton Airport (LTN) to Stansted Airport (STN) is by train via London. The journey involves taking a Thameslink train to London St Pancras, transferring across London to Liverpool Street station (via Tube or taxi), and then catching the Stansted Express. Total travel time is approximately 2 to 2.5 hours, with costs ranging from £30 to £60+ depending on how you book. The cheapest option is a combination of National Express coaches, taking 3-4 hours for about £15-£25 if booked well in advance.
By Train: The Fastest Public Transport Route
The rail journey is the most efficient public transport link between the two airports, leveraging London's major rail hubs. It's a multi-leg journey but offers good frequency and speed.
Step-by-Step Guide: The Standard Route
- Luton Airport to Luton Airport Parkway: Take the free, frequent Luton DART shuttle from the terminal. Journey time: 4 minutes.
- Luton Airport Parkway to London St Pancras International: Board a Thameslink train. Services run every 10-15 minutes. Journey time: 25-50 minutes depending on the service (semi-fast vs. stopping).
- Cross-London Transfer (St Pancras to Liverpool Street):
- Tube (Recommended): Take the Hammersmith & City, Circle, or Metropolitan line eastbound directly to Liverpool Street station. Time: ~20 minutes.
- Taxi/Walk: A taxi takes 10-15 minutes but can be costly (£10-£15). Walking is not practical with luggage (approx. 1.5 miles).

Ticket Types, Costs & Booking Strategy
| Ticket / Leg | Approx. Cost (One-Way) | Booking Advice | Key Consideration |
|---|---|---|---|
| Thameslink (Luton to London) | £10 - £25 (Anytime) | Use contactless/Oyster for cheapest off-peak fare. Book advance singles via train operators for fixed times. | Peak hours (6:30-9:30 AM into London) are significantly more expensive. |
| London Underground Transfer | £2.50 - £5 (Peak) | Use the same contactless/Oyster card. Included in daily fare cap. | Part of TfL network; fare depends on time of day. |
| Stansted Express | £10 (Advance) - £21 (Walk-up) | BOOK IN ADVANCE ONLINE. Advance tickets can be 50% cheaper and are for a specific train. | Walk-up fares are very high. Advance tickets sell out. |
| Combined Total (Budget) | £25 - £35 | Book Thameslink advance + Stansted Express advance. | Requires commitment to specific train times. |
| Combined Total (Flexible) | £45 - £60+ | Use contactless for Thameslink/Tube + walk-up Stansted Express. | Maximum flexibility but most expensive. |
Pro Tip: Check if a "Super Off-Peak" ticket is available for your Thameslink journey, offering deep discounts for travel outside busy times.
By Coach / Bus: The Most Budget-Friendly Option
For cost-conscious travellers without tight time constraints, long-distance coaches (buses) offer the lowest fares. This is a direct bus-to-bus service, avoiding central London train stations.
The Standard Coach Route: Via London Victoria
The most straightforward coach route involves one change at London's main coach station.
- Luton Airport to London Victoria Coach Station: Take either the National Express A1 or the Green Line 757 service. Both run frequently (every 20-60 minutes). Journey time: 60-90 minutes depending on traffic.
- London Victoria to Stansted Airport: Transfer to the National Express A9 or A10 coach. Services run hourly. Journey time: approx. 90 minutes to 2 hours.
Total Journey Time: 3 to 4.5 hours (highly traffic-dependent). Total Cost (Advance Booking): £15 - £30.
Key Operator Details & What to Know
| Operator | Route | Frequency | Luggage Allowance | Booking Site |
|---|---|---|---|---|
| National Express | A1 (LTN to Victoria) & A9/A10 (Victoria to STN) | Very Frequent / Hourly | 1 large suitcase + 1 carry-on included | nationalexpress.com |
| Green Line | 757 (LTN to Victoria) | Every 30 mins | Limited space, may incur fees for large bags | greenline.co.uk |
Advantages: Very cheap, direct to airport terminals, comfortable coaches with WiFi/USB.
Disadvantages: Long journey time, severely impacted by London/M25 traffic, less frequent late at night.
Essential Tip: Always book online in advance for the lowest "Fun Fares". The price difference between booking a week ahead and on the day can be over 100%.
By Taxi or Private Transfer: Door-to-Door Convenience
This is the most straightforward but also the most expensive method, suitable for specific needs rather than general travel.
Costs & Practicalities
- Approximate Distance: 50-60 miles (80-95 km).
- Approximate Travel Time: 1 hour 15 minutes to 2+ hours, heavily dependent on M1/M25 motorway traffic.
- Approximate Cost (Pre-Booked Private Transfer): £120 - £180 for a standard saloon car.
- Approximate Cost (Black Cab/Metered Taxi): £180 - £250+. Not recommended due to extremely high cost.
When Does a Private Transfer Make Sense?
Consider this option only if:
- You are travelling in a group of 3-4 people, splitting the cost makes it comparable to train fares.
- You have a lot of luggage or bulky equipment (e.g., sports gear, musical instruments).
- You are travelling with very young children, elderly companions, or have mobility issues.
- Your flight arrives very late at night or departs very early in the morning when public transport is not running.
- Your connection time is critically tight and you cannot risk any delays on public transport.
Booking Advice: Use reputable pre-booked minicab services like MiniCabIt, HolidayTaxis, or local Luton/Stansted firms. Pre-booking fixes the price and ensures a driver meets you at arrivals. Avoid unlicensed touts.
Cost & Time Comparison: Luton (LTN) to Stansted (STN)
| Transport Method | Approx. Journey Time | Approx. Cost (One-Way) | Key Advantage | Key Disadvantage | Best For |
|---|---|---|---|---|---|
| Train via London | 2 - 2.75 hrs | £25 - £60+ | Fastest public transport, reliable schedule | Multiple changes, can be expensive last-minute | Solo travellers, couples, those on a moderate schedule |
| Coach via Victoria | 3 - 4.5 hrs | £15 - £35 | Cheapest option, direct to terminals | Very slow, traffic-vulnerable | Budget travellers, flexible schedules |
| Private Transfer / Taxi | 1.25 - 2+ hrs | £120 - £250+ | Door-to-door, no hassle with luggage | Extremely expensive, traffic-vulnerable | Groups, special needs, odd-hour travel |
Verdict: The train offers the best balance of speed and cost for most. The coach wins on pure budget. Private transfer is a premium solution for specific circumstances.
Essential Travel Tips & Insider Experience
1. Buffer, Buffer, Buffer!
If you have a flight to catch at your destination airport, treat this as an international connection, not a simple bus ride. Allow a minimum of 4-5 hours between your scheduled landing time at Luton and your needed check-in time at Stansted. This accounts for potential flight delays, baggage reclaim, passport control (if arriving from outside the UK), and unexpected delays on the road/rails.
2. The Luggage Challenge
Navigating the Tube with large suitcases between St Pancras and Liverpool Street is challenging. Stations like King's Cross St. Pancras are vast and often have stairs or long walks. If you have heavy bags:
- Consider taking a taxi for the cross-London leg (adds £10-15 but saves stress).
- Use lifts (elevators) where available—look for the wheelchair-accessible signs.
- Pack light if possible. This journey is not suited for those with multiple large bags per person.
3. The "Golden Rule" of Ticketing
Never, ever walk up to buy a Stansted Express ticket on the day. The walk-up fare is punitive. Always book it online in advance, even if it's just a few hours before. The saving is substantial.
4. Technology is Your Friend
Download essential apps before you travel:
- Citymapper or Google Maps: For real-time Tube/bus directions in London.
- National Rail Enquiries: For live train times and platform information.
- National Express/Green Line Apps: To store your mobile coach ticket.
5. Consider the "Third Airport" - London Heathrow?
In some rare cases (e.g., a very long layover, specific airline routes), it may be worth checking flight prices from London Heathrow (LHR) instead of Stansted. The coach connection from Luton to Heathrow (National Express 707) is direct and takes about 1 hour. However, this only makes sense if your final destination is better served from Heathrow.
Frequently Asked Questions (FAQs)
Is there a direct train from Luton Airport to Stansted Airport?
No, there is no direct train service connecting Luton Airport (LTN) and Stansted Airport (STN). The journey requires at least one change, typically in London. The most common and efficient route is by taking a Thameslink train to London St Pancras International, then transferring to the London Underground (Tube) or a taxi to Liverpool Street station, and finally catching the Stansted Express train to Stansted Airport.
What is the cheapest way to get from Luton to Stansted Airport?
The cheapest way is by taking a combination of coach services. First, take the National Express A1 or Green Line 757 bus from Luton Airport to London Victoria Coach Station. From there, transfer to a National Express A9 or A10 coach directly to Stansted Airport. Advance online bookings can cost as low as £15-£25 total for the combined journey, though travel time is longer (approx. 3-4 hours).
How long does the train journey from Luton to Stansted take?
The total train journey time, including transfers, typically takes between 2 hours and 2 hours 45 minutes. This includes: the Thameslink train from Luton Airport Parkway to London St Pancras (25-50 mins), the transfer across London via Tube/taxi (20-40 mins), and the Stansted Express from London Liverpool Street to Stansted Airport (47 mins). Delays during peak hours or missing a connection can extend this time.
Can I use an Oyster or Contactless card for the entire journey?
No, you cannot use Oyster or Contactless payment for the entire journey. You can use them for the Thameslink train into London and for the London Underground transfer. However, the final leg on the Stansted Express from London Liverpool Street to Stansted Airport requires a separate ticket, which is not part of the Transport for London (TfL) fare system. You must purchase a specific train ticket for this segment.
What is the best option for an early morning or late-night transfer?
For very early morning (before 5:30 AM) or late-night (after midnight) transfers, public transport options are severely limited or non-existent. Your most reliable options are: 1) A pre-booked private transfer or taxi, which operates 24/7 but is expensive (£120-£180). 2) Staying at an airport hotel at one airport and taking the first available public transport the next morning. Always check the latest timetables for the first/last trains and coaches.
Is it worth booking a private transfer between the airports?
A private transfer is worth it only in specific circumstances: for large groups (3+ people) where the cost can be split, for travellers with a lot of luggage or mobility issues, or for those on a very tight schedule where a missed connection would be disastrous. For solo travellers or couples, it is generally not cost-effective compared to trains or coaches. It offers door-to-door convenience but at a premium price of £120-£180.
How far in advance should I book train or coach tickets?
For the best fares, book as far in advance as possible, especially for the Stansted Express train leg. Train tickets are often released 8-12 weeks ahead, and advance singles can be significantly cheaper. Coach tickets (National Express) also offer lower 'Fun Fares' for early bookings. For travel during peak seasons (summer, Christmas) or on weekends, aim to book at least 4-6 weeks ahead to secure availability and better prices.
What happens if my first flight is delayed and I miss my booked transfer?
Policies vary by provider. For flexible train tickets (Anytime or Off-Peak), you can usually take a later train. However, advance train tickets and most coach tickets are tied to a specific departure time and are often non-refundable and non-changeable. It is crucial to build a large buffer (at least 4-5 hours between flight landing and your transfer departure) to account for delays, baggage claim, and passport control. Consider travel insurance that covers missed connections.
