Quick Answer
For most travelers, the best overall way to transfer from Don Mueang (DMK) to Suvarnabhumi (BKK) is the AOT Airport Shuttle Bus: it's direct, costs only 50 THB, and takes about 60-80 minutes. The fastest reliable option is a pre-booked private car (45-60 mins), while the cheapest is Public Bus 554 (35-40 THB, 60-90 mins). There is no direct train; a train combo (Red Line + ARL) is possible but complex with luggage.
Option 1: Train Combo (SRT Red Line & Airport Rail Link)
While there's no direct train, a connection using Bangkok's newer rail lines is feasible for travel-light, adventurous passengers. It involves two separate train systems.
Pros: Punctual, avoids road traffic, very cheap.
Cons: Multiple transfers with luggage, walks between stations, not 24/7.
Step-by-Step Guide:
- Walk to Don Mueang Train Station: It's a 10-15 minute covered walk from DMK Terminal 2 (follow signs).
- Take the SRT Dark Red Line: Buy a ticket to Bang Sue Grand Station (the terminus). Cost: ~33 THB. Time: 15 mins.
- Transfer to the MRT Blue Line or SRT Light Red Line: At Bang Sue, follow signs to transfer to the MRT (subway) heading to Taopoon Station (just one stop) or take the Light Red Line one stop to Bang Son.
- Take the Airport Rail Link (ARL): From Taopoon (MRT) or Bang Son (Light Red), you need to get to Makkasan Station or Phaya Thai Station to access the ARL. This requires another MRT/ARL transfer. Then, take the ARL express or city line to Suvarnabhumi Airport (BKK). ARL Cost: 35-45 THB. Time: 25-30 mins.
Total Estimated: Cost: ~70-120 THB. Time: 70-100 minutes (excluding wait/walk times). Not recommended with large suitcases or during peak hours.
Option 2: AOT Airport Shuttle Bus (Recommended)
Operated by Airports of Thailand (AOT), this is the official, dedicated shuttle service. It's the best balance of cost, comfort, and convenience.
Key Details:
- Route: Direct between DMK and BKK.
- Frequency: Every 30-60 minutes.
- Operating Hours: Approximately 05:00 - 24:00 (confirm on arrival).
- Travel Time: 60-80 minutes, subject to traffic.
- Ticket Price: 50 THB per person (pay onboard, exact change helpful).
- Luggage: Stored in the hold, typically no strict limit per person for standard travel luggage.
Where to Find It:
- At DMK: Go to the 1st floor, Gate 6 at Terminal 1. Look for the "Airport Shuttle" sign.
- At BKK: Go to the 2nd floor (Arrivals Level), Gate 5.
No advance booking is required. Just queue and board. This service is highly reliable and used by airport staff and flight crews.
Option 3: Public Bus (The Cheapest Way)
For the ultimate budget traveler, regular public buses connect the airports. Bus 554 (DMK - BKK Direct) and Bus 555 (Suvarnabhumi - Rangsit via DMK) are the key routes.
| Bus Number | Route | Frequency | Fare | Estimated Time | Notes |
|---|---|---|---|---|---|
| 554 | Don Mueang - Suvarnabhumi (Direct) | Every 20-40 mins | 35-40 THB | 60-90+ mins | Best direct public bus option. Can be slow in heavy traffic. |
| 555 | Suvarnabhumi - Rangsit (via Don Mueang) | Every 30-60 mins | ~50 THB | 70-100 mins | Also works, but ensure it stops at DMK. |
How to Take the Bus:
- At DMK: Bus stops are on the ground floor (1st floor) outside Terminal 1. Look for the bus stop shelters with route numbers.
- Payment: Pay the conductor in cash after boarding. Have small bills.
- At BKK: The bus will drop you at the Transportation Center, from which a free airport shuttle bus runs to the passenger terminals.
Warning: Buses can be crowded, have limited space for large bags, and travel time is highly unpredictable. Only recommended if you are on an extreme budget and have light, manageable luggage.
Option 4: Taxi & Private Transfer (Door-to-Door)
The most convenient, door-to-door option, ideal for families, groups, those with heavy luggage, or arrivals during late hours.
Metered Taxi (From Official Queue):
- Cost: Meter starts at 35-40 THB. Total fare typically 500-700 THB.
- Additional Charges:
- Airport Surcharge: 50 THB (added at DMK).
- Tollway Fees: 70-100 THB (paid by passenger, keeps journey faster).
- Total Expected Cost: 550 - 850 THB.
- Time: 45-75 minutes, heavily dependent on traffic.
- How to Get One: Follow "Taxi" signs to the official taxi stand on the 1st floor of DMK. Take a ticket with a queue number. Always insist "Meter, please" and ensure it's turned on.
Pre-Booked Private Car (Recommended for Peace of Mind):
Book online via services like Klook, Viator, or local companies. A driver will meet you at arrivals with a name sign.
- Cost: 900 - 1,500 THB for a standard sedan.
- Pros: Fixed price (no meter surprises), meet-and-greet, often includes tolls, cleaner/more comfortable cars, English-speaking driver.
- Perfect for first-time visitors, late-night arrivals, or stressful connections.

Traveler Tips & Hacks for a Smooth Transfer
Essential Advice:
- Factor in Traffic: Bangkok traffic is notorious. Always add a 60-90 minute buffer to any road-based transfer (bus, taxi) for your flight check-in at BKK.
- Layover Minimum: If you are self-transferring between airlines, a minimum of 4 hours between landing at DMK and your next flight from BKK is strongly advised.
- Money: Have small Thai Baht notes for buses, shuttle, and tolls. Taxis often claim not to have change for large bills.
- Sim Card/Data: Buy a local tourist SIM at DMK Arrivals. Having internet for maps and rideshare apps is invaluable.
- Late-Night Arrivals: If your flight lands after ~11:30 PM, your only realistic options are taxi or pre-booked car. Plan and budget accordingly.
Luggage Hacks:
- Pack Light for Public Transport: If using bus/train, one carry-on-sized backpack or roller is the maximum for a comfortable trip.
- Luggage Storage: Both airports offer left luggage services. If you have a long layover and want to explore, consider storing bags first. Rates are ~100-150 THB per bag per day.
Frequently Asked Questions (FAQs)
Is there a direct train between Don Mueang and Suvarnabhumi Airports?
No, there is no direct train line connecting Don Mueang Airport (DMK) and Suvarnabhumi Airport (BKK). The most efficient rail-based method involves a combination of the SRT Red Line commuter train and the Airport Rail Link (ARL), requiring a change at Makkasan Station (ARL) or Bang Sue Grand Station (for the Red Line). This journey is not recommended for those with more than small carry-on luggage.
What is the cheapest way to get from DMK to BKK?
The cheapest option is the public bus. Bus line 554 runs directly between the two airports for a fare of only 35-40 THB (approx. $1 USD). However, travel time can be 60-90 minutes depending on Bangkok traffic, making it the best choice for budget travelers without heavy luggage who are not in a rush.
What is the fastest way to transfer between the two airports?
The fastest reliable method is a pre-booked private taxi or airport shuttle, taking 45-60 minutes outside of peak traffic hours. While the train combo can be faster in theory (50-70 mins), the need to change trains and walk between stations adds significant time and hassle, especially with luggage, making road transport faster in practice.
How much does a taxi cost from Don Mueang to Suvarnabhumi?
A metered taxi costs between 500-700 THB ($14-20 USD), plus potential tollway fees (70-100 THB) and a 50 THB airport surcharge. The total journey typically ranges from 550-850 THB. Always insist on the meter ('meter, please') and be prepared for potential traffic delays which can increase the final meter cost.
Can I use the same shuttle bus for both airports?
Yes, the official airport shuttle bus service operated by the Airports of Thailand (AOT) is a dedicated, comfortable option. It runs every 30-60 minutes, costs 50 THB per person, and takes about 60-80 minutes. It's a good middle-ground between public buses and taxis in terms of cost, reliability, and convenience.
I arrive late at night. What are my options?
After midnight, public train and bus services are extremely limited or stop. Your primary options are: 1) Metered Taxi (available 24/7 at taxi stands), 2) Pre-booked Private Transfer (highly recommended for reliability and safety), or 3) Rideshare apps (Grab/Bolt), though pick-up points may be less convenient and drivers scarce. Plan and book ahead for late-night arrivals.
I have a long layover (6+ hours). Is it worth leaving the airport?
With 6+ hours, you can consider a quick trip into the city. However, you must account for 2-3 hours total transfer time round-trip and strict airport re-check-in/security times (at least 2 hours before a domestic flight, 3 hours for international). It's only advisable if you have a very long layover (8+ hours) and light luggage. Consider leaving bags at luggage storage services in either airport first.
Is the transfer easy with lots of luggage or young children?
Not with public transport. The train combo involves stairs, long walks, and crowded carriages. Buses have limited space. With heavy luggage or young children, the hassle and stress outweigh any cost savings. We strongly recommend a pre-booked private car or taxi for door-to-door service, despite the higher cost. It's the safest and most comfortable choice for families and those with lots of bags.
