Quick Answer
For most travelers transferring between Bangkok's airports, the best overall option is the official, free airport shuttle bus if you have a connecting flight ticket. It's direct, takes about 60-90 minutes, and costs 0 THB (free). The fastest option in light traffic is a taxi or private car (45-60 mins, 500-800 THB / $14-$22). The cheapest public option is the local public bus route 554 (approx. 35 THB / $1), but it is slow (2+ hours). There is no single direct train; a train combination takes 70-90 minutes and costs ~100 THB ($2.80).
1. Free Airport Shuttle Bus (Best for Connecting Passengers)
This is the most recommended method for passengers with a connecting flight. Operated by the Airports of Thailand (AOT), it's a dedicated, comfortable coach service.
Who is it for? Passengers with a same-day confirmed ticket for an onward flight from the other airport. You must show your boarding pass or e-ticket itinerary.
| Feature | Details |
|---|---|
| Cost | FREE (for qualifying passengers) |
| Travel Time | 60 to 90 minutes, depending on traffic |
| Frequency | Every 30-60 minutes |
| Operating Hours | Approx. 5:00 AM to 11:00 PM (confirm at counter) |
| Luggage | Ample storage in under-bus compartments |
| Where to Board at DMK | Gate 6 on the 1st floor of Terminal 2. Look for the "Airport Shuttle Bus to BKK" sign. |
| Where it Drops at BKK | Level 2, Gates 3, 4, 7, or 8 (varies). Ask the driver. |
Step-by-Step Guide & Important Notes
Step 1: After collecting your luggage at Don Mueang, proceed to the 1st floor (Arrivals Level) of Terminal 2.
Step 2: Find the AOT Airport Shuttle Bus counter near Gate 6. Present your passport and your confirmed flight ticket/boarding pass for a flight departing from Suvarnabhumi Airport (BKK) later that same day.
Step 3: You will receive a ticket and be directed to the waiting bus. Buses are air-conditioned and comfortable.
Note: Schedules can be irregular. Always allow a minimum of 4 hours between your landing at DMK and your departure from BKK to account for bus wait time, traffic, and check-in. For official details, check the AOT website.
2. By Train (The Scenic & Urban Adventure)
While there's no direct line, a train journey is possible and offers a glimpse of Bangkok's modern rail network. It involves three separate systems and is best for travelers with light luggage who are not in a rush.
The Route: DMK (SRT Red Line) → Bang Sue Grand Station (Transfer) → (MRT Blue Line) → Makkasan or Phetchaburi Station (Transfer) → (Airport Rail Link - ARL) → Suvarnabhumi Airport (BKK).
| Leg of Journey | Train System | Approx. Time | Approx. Cost | Key Notes |
|---|---|---|---|---|
| DMK to Bang Sue | SRT Dark Red Line | 15-20 mins | 15-20 THB ($0.40-$0.55) | Station is a 10-min walk from DMK Terminal 2 via footbridge. |
| Bang Sue to Makkasan/Phetchaburi | MRT Blue Line | 15 mins | 25-30 THB ($0.70-$0.85) | Follow signs for the MRT inside Bang Sue Station. Phetchaburi is directly connected to the ARL. |
| Makkasan/Phetchaburi to BKK | Airport Rail Link (ARL) | 25-30 mins | 35-45 THB ($1-$1.25) | Express trains are slightly faster but less frequent. |
| TOTAL | 3 Systems | 70-90 mins (plus transfer time) | ~75-95 THB (~$2.80) | Requires multiple ticket purchases. Not suitable with heavy bags. |
Deep Dive: Stations, Transfers, and Tickets
Starting Point - Don Mueang Station (SRT): This station is not inside the airport. Exit Terminal 2, use the elevated walkway (follow signs), and walk for about 10 minutes. Purchase a token for the SRT Dark Red Line to Bang Sue Grand Station.
The Hub - Bang Sue Grand Station: This is a massive station. After exiting the SRT gates, look for signs to the MRT Blue Line. You will need to exit and re-enter through separate ticketing gates. Buy a token for the MRT to Phetchaburi Station (not Makkasan, for a seamless transfer).
Final Transfer - Phetchaburi Station (MRT/ARL): At Phetchaburi, follow signs for the Airport Rail Link (ARL). The systems are physically connected. Purchase a separate ticket for the ARL to Suvarnabhumi Airport (BKK).
Payment: No single ticket covers all. Use cash for tokens (SRT, MRT) or buy a single-ride ticket for the ARL. Regular commuters use different contactless cards for each system.
3. By Public Bus (The Budget Champion)
For the absolute lowest cost, the public bus is unbeatable. However, it is the slowest and least comfortable option, entirely subject to Bangkok's gridlock.
Recommended Route: Bus 554 (Don Mueang - Suvarnabhumi). This is the most direct public bus route.
| Aspect | Details |
|---|---|
| Cost | Approx. 35 THB (about $1). Exact fare paid to conductor. |
| Travel Time | 2 to 3+ hours. Highly unpredictable due to traffic. |
| Frequency | Every 20-30 minutes. |
| Operating Hours | Early morning until late evening (approx. 4:00 AM - 10:00 PM). |
| Where to Board at DMK | From the public bus stop on the ground floor (Level 1) outside Terminal 1. Look for the sign for bus 554. |
| Where it Drops at BKK | At the Public Transportation Center, from where you take a free shuttle bus to the passenger terminal (adds 10-15 mins). |
Practical Realities & Alternative Buses
The Experience: Buses can be crowded, non-air-conditioned (or old A/C buses), and make many stops. Not recommended with large suitcases or during peak heat hours.
Alternative Routes: You can also take bus A1 or A2 from DMK to Victory Monument, then take bus 551 to BKK. This might be slightly faster if traffic is lighter on that route, but it involves a bus-to-bus transfer in an area that can be confusing for newcomers.
Who is it for? Solo backpackers or ultra-budget travelers with very light luggage, plenty of time, and a high tolerance for adventure and discomfort. Always have small change for the fare.
4. By Taxi or Private Transfer (Door-to-Door Convenience)
This is the most straightforward, door-to-door option, ideal for families, groups, those with heavy luggage, or travelers arriving late at night.
Key Advantage: Direct from DMK arrivals to BKK departures. No transfers, no walking with bags.
| Option | Cost (Approx.) | Travel Time | How to Book/Find | Best For |
|---|---|---|---|---|
| Official Airport Taxi | 500 - 800 THB ($14 - $22) + possible 50 THB airport fee + tolls (70-100 THB) | 45 - 90 mins | Follow "Public Taxi" signs to the official desk on Level 1. Get a ticket with driver details. | Most travelers needing a cab. Insist on "Meter On". |
| Ride-Hail (Grab/Bolt) | 500 - 900 THB ($14 - $25) - dynamic pricing | 45 - 90 mins | Use the app. Designated pick-up points at DMK. | Those wanting upfront pricing and cashless payment. |
| Pre-Booked Private Car | 1,200 - 2,000 THB ($33 - $55) | 45 - 90 mins | Book online via Klook, KiwiTaxi, or hotel concierge. | Groups of 3-4, guaranteed service, late-night arrivals, stress-free travel. |
Cost Breakdown, Tolls, and Tips
Understanding the Cost: The meter should start at 35-40 THB. The total will be Meter Fare + 50 THB Airport Surcharge + Tolls. Tolls on the expressway are paid by the passenger (keep small bills). The driver may propose a flat fare; it's often better to insist on the meter ("Meter, please").
Traffic is Everything: The quoted time and cost range is vast because of traffic. A late-night trip can be quick and cheap (on meter), while a 5 PM trip will be long and costly.
Pre-Booking Advantage: A pre-booked car, while more expensive, offers fixed pricing (no surprise meter jumps), an English-speaking driver who tracks your flight, and a meet-and-greet with a name sign. This is invaluable after a long flight.
5. Ticket & Cost Comparison: Which is Best for You?
This table summarizes all key data to help you decide at a glance.
| Transport Method | Approx. Cost (THB / USD) | Approx. Travel Time | Convenience / Comfort | Best Suited For | Key Consideration |
|---|---|---|---|---|---|
| Free Shuttle Bus | 0 / $0 | 60-90 mins | High (Direct, A/C coach) | Passengers with a connecting flight ticket | Must show proof of onward flight from the other airport. |
| Public Bus (554) | 35 / $1 | 120-180+ mins | Very Low (Traffic, stops, crowds) | Ultra-budget, light-packers with ample time | Extremely unpredictable. Not for tight schedules. |
| Train Combo | ~100 / ~$2.80 | 70-90 mins + transfer time | Medium (A/C trains, but multiple transfers) | Solo travelers/backpackers with light luggage | Complex with bags. Walk between systems. |
| Taxi (Metered) | 500-800+ / $14-$22+ | 45-90 mins | High (Door-to-door) | Couples, those with luggage, general convenience | Cost/time vary wildly with traffic. Insist on meter. |
| Pre-Booked Private Car | 1,200-2,000 / $33-$55 | 45-90 mins | Very High (Guaranteed, meet & greet) | Families, groups, late-night, stress-free priority | Fixed price. Most reliable and comfortable option. |
Decision Summary: If you qualify, take the free shuttle. If not, and you value time/convenience, choose a taxi or private car. If you are on a severe budget and have time, consider the train (over the bus) for a more reliable schedule.
6. Traveler Experience & Insider Tips
Beyond schedules and fares, here are practical insights from frequent travelers.
Luggage Strategy
- Heavy Bags? Avoid the train. The walks and stairs between SRT, MRT, and ARL are challenging with rollers and backpacks.
- Shuttle Bus Luggage: Use the under-coach storage. Keep valuables in a small bag with you.
- Taxi Tip: Have a photo of your luggage ready. Reputable drivers at the official taxi desk will note the number of bags.
Timing is Crucial
- Minimum Connection Time: Always allow at least 4 hours between your scheduled arrival at DMK and departure from BKK. For international connections, 5+ hours is safer to account for immigration, baggage, traffic, and airline check-in deadlines.
- Bangkok Rush Hours: (7:00-9:30 AM and 4:00-8:00 PM). Add at least 60-90 minutes to any road-based transfer (Shuttle, Taxi, Bus) during these times.
- Late Night/Early Morning: Public transport options are limited or nonexistent. A pre-booked private transfer is the most reliable choice.
Navigation & Communication
- Have Your Destination Written in Thai: For taxi drivers, have "สนามบินสุวรรณภูมิ" (Suvarnabhumi Airport) saved on your phone or written down.
- Use Maps Offline: Download the Bangkok area on Google Maps to navigate train stations without data.
- Airport Information Desks: If confused at DMK, go to the AOT Information Desk on Level 2 for the most accurate, current advice on all transport options.
FAQs: Don Mueang to Suvarnabhumi Airport Transfer
Is there a direct train from Don Mueang Airport to Suvarnabhumi Airport?
No, there is no single direct train connecting Don Mueang (DMK) and Suvarnabhumi (BKK) airports. The most efficient public transport route involves taking the SRT Red Line commuter train from DMK to Bang Sue Grand Station, then transferring to the MRT Blue Line to Phetchaburi Station, and finally walking to the Airport Rail Link (ARL) station for the train to BKK. This requires multiple transfers and tickets.
What is the cheapest way to get from DMK to BKK?
The cheapest option is the official airport shuttle bus, provided for free to passengers with a connecting flight ticket from the opposite airport. The public bus (route 554) is also very affordable at around 35 THB ($1), but it is much slower and less convenient due to Bangkok traffic.
How long does a taxi take between the two airports?
A taxi or private transfer typically takes 45 to 90 minutes, heavily dependent on Bangkok's notorious traffic. During peak hours (7-9 AM, 4-7 PM), the journey can easily exceed 90 minutes. At night with minimal traffic, it might take as little as 40 minutes.
Can I use the same ticket for all trains between the airports?
No. The train journey involves three separate systems: the SRT Red Line, the MRT Blue Line, and the Airport Rail Link (ARL). You will need to purchase a separate ticket or use a different contactless card for each system. The Rabbit Card works on the ARL and BTS, while the MRT and SRT have their own cards or token systems.
What is the best option for a late-night or early-morning transfer?
For transfers outside public transport operating hours (roughly 6:00 AM to midnight), a taxi or pre-booked private transfer is your only reliable option. The shuttle bus has limited hours, and trains do not run 24/7. Pre-booking a car is highly recommended for peace of mind during these times.
Is the shuttle bus free for everyone?
No, the shuttle bus is specifically for air passengers with a same-day connecting flight ticket from the other airport. You must show your boarding pass or flight itinerary for the upcoming flight from Suvarnabhumi (if coming from Don Mueang) or Don Mueang (if coming from Suvarnabhumi) to board for free.
Which option is best with a lot of luggage?
A taxi or private car is by far the best option with heavy or multiple bags. The train route involves significant walking, stairs, and crowded carriages, which can be challenging with luggage. The shuttle bus has storage compartments, making it a good middle-ground if you qualify for the free service.
Should I fly between Don Mueang and Suvarnabhumi?
Flying is not a practical option. There are no scheduled commercial flights between Don Mueang (DMK) and Suvarnabhumi (BKK) as they are both in the same metropolitan area. The time and cost of checking in, passing security, flying, and collecting baggage would be vastly greater than any ground transport option.
