Bangkok Airport Rail Link

The Bangkok Airport Rail Link is the cheapest way from Suvarnabhumi Airport (BKK) into the city, and traffic cannot slow it down: 45 THB and about 26 to 30 minutes to Phaya Thai, with trains from 05:30 to midnight. The line has had a rough 2026, with a depot derailment, wheel-inspection slowdowns and an operator handover. Take it if you travel light and land in the daytime. If you land late, travel as a family or carry heavy luggage, book a car instead.

Rail link essentials

• The Airport Rail Link (ARL) is a single 28.6 km line with 8 stations. It runs from Suvarnabhumi, Level B1 under the terminal, to Phaya Thai, where you change to the BTS Skytrain. It does not serve Don Mueang (DMK).
• Fares are 15 to 45 THB by distance. Pay with a contactless Visa, Mastercard, JCB or UnionPay card, a token or the ARL stored-value card. Rabbit cards are not accepted. Trains run 05:30 to midnight, with six to eight trains in service depending on demand, the Bangkok Post reported.
• Skip it if you land after about 22:30, travel as a family or group, have big suitcases, or your hotel is far from a BTS or MRT station. A taxi, Grab or a pre-booked private transfer is easier then.

What the Airport Rail Link is

The Airport Rail Link, also called the airport link or the Bangkok airport train, is an elevated commuter railway between Suvarnabhumi and central Bangkok. It opened in August 2010. For several years it ran two services: the all-stops City Line and a non-stop Express Line from Makkasan to the airport, paired with in-town check-in. The Express Line and the Makkasan City Air Terminal check-in were both suspended in September 2014 because of a shortage of trains and low demand, and neither has come back. Some airport signs still show a red “Express” icon, but every train today is a City Line train that stops at all eight stations.

Who runs the line in 2026

The SRT owns the line. Since October 2021 it has been run by Asia Era One, a consortium led by Charoen Pokphand (CP). That arrangement was part of the much larger Don Mueang–Suvarnabhumi–U-Tapao high-speed rail (HSR) public-private partnership. In July 2026 Asia Era One formally sought to end the HSR contract, and with it the ARL operation. After weeks of talks, the SRT and Asia Era One signed a temporary agreement on 29 September covering 1 October 2026 to 31 January 2027. Transport Minister Phiphat Ratchakitprakan said the deal leaves out the 60 million baht monthly operating fee Asia Era One had sought, so the operator relies on fare revenue. SRTET, the SRT subsidiary that already runs the Red Line, is due to take over on 1 February 2027.

For your trip, that means:

• The trains, stations and fares stay the same through the handover. Thaiger reports that passengers keep using the same trains.
• The three-airport high-speed line, which would one day link Don Mueang and Suvarnabhumi by rail, was still unresolved in October 2026. Do not plan around it.
• Brief service wobbles around the handover are possible, so check the official channels on the day you fly.

Airport Rail Link stations, in order

Trains run on one line with no branches: Suvarnabhumi, Lat Krabang, Ban Thap Chang, Hua Mak, Ramkhamhaeng, Makkasan, Ratchaprarop, Phaya Thai. Fares from the airport rise in 5 THB steps.

The station fares above come from 2026 travel guides and the fare boards at the stations. We found no official fare table online, so the boards at the gates have the final word.

Fares and tickets

How much the Airport Rail Link costs

Fares go by distance, from 15 THB for one stop to 45 THB for the full ride from Suvarnabhumi to Phaya Thai. Makkasan, the change for the MRT, costs 35 THB. Travel guides report that children under 90 cm ride free. We could not confirm any discount fares for visitors, such as student or senior fares, from an official source.

Ways to pay

1. Contactless bank card, the easiest. Tap-to-pay launched at every ARL station on 8 November 2025, rolled out by the Department of Rail Transport under Director-General Pichet Kunadhamraks. Thai government and press reports list Visa, Mastercard, JCB and UnionPay cards with the contactless symbol. Tap at the marked gates going in and coming out, and the system charges the right fare. At Suvarnabhumi and Phaya Thai you tap a separate reader in front of an open gate. Always tap in and out with the same card or phone; mixing them can trigger an incomplete-trip charge.
2. Single-journey token. Buy one from the ticket machines (English menu) or the staffed counter. The machines can be fussy with large notes, so carry small bills. Tap the token to enter and drop it in the slot to exit.
3. ARL stored-value card. Mainly useful for residents and regular commuters.

Rabbit cards (BTS) are not accepted. ARL tickets do not carry over to the BTS or MRT, so you pay again on each line. The BTS still does not take contactless bank cards, so you need a BTS single ticket or a Rabbit card there.

The common ticket and the “17 to 45 baht” headlines

You may read that Bangkok rail fares will be capped at 17 to 45 THB. The cabinet approved a common-ticketing scheme on 23 June 2026, aiming to start on 1 January 2027. The version the Transport Ministry outlined in October 2026 is a refund paid through the Paotang app to registered Thai citizens only: passengers pay the full fare first and get money back afterwards. As designed, foreign visitors keep paying normal fares on each line. Details could change before launch.

First train, last train and how often they run

• First train: 05:30 from both Suvarnabhumi and Phaya Thai.
• Last train: around midnight from both ends. Older timetables showed a last weekend departure of 00:08, but 2026 Bangkok Post reporting simply says midnight in both directions. Assume midnight.
• Frequency: travel guides quote about every 10 to 11 minutes at peak times (about 06:00 to 09:00 and 16:00 to 20:00) and every 12 to 15 minutes off-peak and at weekends. The Bangkok Post described the normal 2026 timetable as roughly every 10 minutes.
• Journey time: about 26 to 30 minutes from Suvarnabhumi to Phaya Thai and about 20 minutes to Makkasan. The line runs on its own track above the roads, so the time barely changes through the day.

If your flight lands after about 22:30, immigration, baggage claim and the walk to Level B1 can easily push you past the last train. After a long-haul flight, do not gamble on it.

Finding the train at Suvarnabhumi

Airports of Thailand puts the ARL station on Level B1, the basement of the Main Terminal.

1. After customs you come out into the arrivals hall on Level 2.
2. Follow the “Airport Rail Link” or “Train to City” signs to the escalators or lifts.
3. Go past Level 1 (taxis and buses) all the way down to Level B1. ATMs, currency exchange and convenience stores sit near the station entrance.
4. Tap your card at the gate or buy a token, then board. At Suvarnabhumi, arriving trains are emptied and briefly checked before staff let passengers on.

Luggage, crowds and access

• Luggage: there are no luggage racks, only standing space by the doors. One normal suitcase per person is fine outside rush hour. Two large cases each on a commuter train is hard work.
• Crowding: weekday peaks, roughly 07:00 to 09:00 and 16:00 to 20:00, fill trains with commuters. The evening rush toward the airport is the worst, and trains can arrive full at Makkasan. Board at Phaya Thai, the end of the line, to get on an empty train.
• Access: travel guides report lifts at all stations and near-level boarding, which helps with wheelchairs and strollers. The awkward exception is the street-level walk to the Yellow Line at Hua Mak.
• Heat and toilets: only the Suvarnabhumi station is air-conditioned; the other seven are open-air elevated platforms. We could not confirm public toilets at every ARL station, so use the terminal’s before you head down.

Changing at Phaya Thai and Makkasan

Phaya Thai to the BTS Sukhumvit Line

1. Leave the ARL gates (tap out or drop your token).
2. Follow the signs down one level and across the covered walkway to BTS Phaya Thai. It is a few minutes’ walk and easy with a roller case.
3. Buy a BTS single-journey ticket (cash or QR at the machines) or use a Rabbit card. Bank cards do not work on the BTS.
4. Siam is two stops away, via Ratchathewi. Nana and Asok are farther along the Sukhumvit Line. For Silom and Sathorn, change at Siam to the Silom Line (Sala Daeng, Chong Nonsi, Saphan Taksin).

Makkasan to the MRT Blue Line (Phetchaburi)

1. Leave the ARL gates at Makkasan.
2. Follow the signs onto the raised, mostly covered skywalk to MRT Phetchaburi. Allow 7 to 10 minutes on foot; it is warm at midday.
3. Go down through the security check to the MRT concourse, then tap a contactless bank card at the gate or buy a token. MRT Blue Line fares are 17 to 45 THB.
4. Sukhumvit (Asok) is one stop away. Carry on to Lumphini or Silom for Silom and Sathorn, or to Wat Mangkon for Chinatown.

Which change suits your area

2026 disruptions and where the line stands

The ARL is normally predictable, but three incidents in 2026 showed how few trains it has.

• 22 July 2026, Khlong Tan depot derailment. A four-car train came off the track at 00:47 while returning to the depot, blocking the only track in and out. For most of the day the line ran one train an hour. SRT Governor Anan Phonimdaeng put on seven special trains, including third-class diesel trains and air-conditioned carriages, on the Lat Krabang–Makkasan–Hua Lamphong route, plus BMTA shuttle buses from Suvarnabhumi Level 2, Gate 9. Full service resumed at 22:07, the Bangkok Post reported, and Asia Era One said it would replace the railway switch and upgrade the depot’s reversing loop.
• 29 to 30 July 2026, power outage. A fault between Lat Krabang and Ban Thap Chang forced trains to share one track near Hua Mak and cut service to every 30 minutes until 09:30 the next morning.
• 7 to 9 September 2026, wheel inspections. Asia Era One president Sarit Jinsit told the Bangkok Post that Siemens, which inspects the fleet, “requested additional checks of train wheel conditions and wear to thoroughly verify the safety and operational readiness of the fleet.” Thaiger reported that wheel wear “sidelined four of the line’s nine trains”, leaving five in service, and SRT Governor Anan Phonimdaeng expected all nine back by 14 September at the latest. Trains ran every 15 minutes (12 minutes for part of 9 September), with replacement buses. The normal timetable returned on the evening of 9 September.
• No new trains yet. As of late September 2026, no extra trains had been ordered. Thaiger reports the SRT is only “considering” buying more.
• October 2026: services ran normally from 1 October under the interim agreement. We found no major disruption reported between 1 and 17 October, which is no guarantee for your day.

Check the status before you travel on the official Airport Rail Link Facebook page, where the operator posts advisories, sometimes late the night before, or call the Era One Call Center on +66 2 091 1595. If the line is running a reduced service on your travel day, a door-to-door car takes the risk away. A fixed-price private transfer can be booked ahead.

Taking the train to the airport

• There is no in-town check-in. The Makkasan City Air Terminal check-in closed in 2014, so you check in at the airport on Level 4.
• Timing: allow about 30 minutes for the ride, plus time to reach the station and perhaps let one full train go. Then add a margin for slowdowns like the 2026 ones. For international flights, aim to reach Suvarnabhumi about three hours before departure.
• Rush hour: on weekday evenings, start at Phaya Thai, not Makkasan, so you board an empty train.
• Early flights: the first train (05:30) will not get you to the airport in time for most departures before about 08:00. Book a car instead.
• At the airport: from Level B1, take the lifts or escalators straight up to departures on Level 4.

When a car beats the rail link

The train suits solo travelers with light bags heading to a hotel near a BTS or MRT station, especially at rush hour. It is the wrong choice in these cases:

• Late-night arrivals: no trains after midnight, and landing after about 22:30 is already risky.
• Families with children: strollers, tired kids and bags on a standing-room commuter train, then a BTS change, make a hard first hour.
• Heavy or several suitcases: there are no racks, and the changes involve walkways and escalators.
• Groups of three or more: the rail and BTS or MRT fares together start to approach the cost of one car, and the car goes to the door.
• Hotels far from stations: Khao San, the riverside and many hotels down side streets still need a taxi at the end.
• Disruption days: see the section above.

Rail link, taxi, Grab, bus or private car

With a pre-booked car, a driver waits in arrivals with your name, the car fits your group and bags, and you know the price before you fly, whatever the time or the state of the train. It suits arrivals near or after midnight, family trips and longer runs such as Bangkok airport to Pattaya or Bangkok airport to Hua Hin. If you are a couple heading to a central hotel, Dida Global’s city center transfer charges per person, $18 each for two travelers (12 October 2026; 4.6/5 from 898 reviews), with the expressway fee and 90 minutes of free waiting. The Suvarnabhumi to Bangkok city guide compares every option by neighborhood, the Bangkok airport taxi guide covers the taxi queue and fares, and the private transfers comparison lists cars and vans for both airports.

Don Mueang travelers: the rail link does not go there

The Airport Rail Link serves Suvarnabhumi only. For Don Mueang, the rail option is the SRT Dark Red Line: Don Mueang to Krung Thep Aphiwat costs 33 THB on SRTET’s August 2026 fare table, and you change to the MRT Blue Line at Bang Sue. See the Don Mueang Airport guide.

Connecting between the two airports? Airports of Thailand runs a free inter-airport shuttle from Suvarnabhumi Level 2, Gate 3, from 05:00 to 24:00, every 30 minutes, for passengers with an onward flight ticket and a passport. The Suvarnabhumi to Don Mueang guide covers the shuttle, taxis and private cars. For everything else at BKK, see the Suvarnabhumi Airport guide.

Should you take the train?

If you are traveling solo or as a couple with light bags and land between early morning and late evening, take the Airport Rail Link: it is cheap, quick and clear of traffic. Check the official Facebook page on your travel day, because the line is changing operators and has had a shaky 2026. If you land late, travel with family or a group, carry a lot of luggage, or want to be driven to the door after a long flight, book a private airport transfer instead.

This guide draws mainly on Airports of Thailand’s Suvarnabhumi transport page, the Bangkok Post, The Nation, Thaiger and The Star/ANN reporting from July to October 2026, SRTET’s Red Line fare table, Thai government and press reports on contactless payment (November 2025) and independent travel guides (Thailand Insider Guide, Mapa-Metro). We checked the facts in October 2026; fares, timetables and operator arrangements can change, so confirm with the operator before you travel.
