Bangkok flooding: Airports open, roads and trains disrupted — what Indian travellers need to know

Where things stand

Two to three days of persistent heavy rain, up to 320 mm, flooded parts of Bangkok, according to the city’s governor. On 26 September the city declared all 50 of its districts flood disaster areas — a step to help authorities respond quickly, not a sign that the whole city is under water.

The flooding is worst in the east and north of the city. At 8.40am on 27 September, the Bangkok Metropolitan Administration’s road sensors showed water at least 20 cm deep on 31 roads across northern, eastern and central Bangkok, including stretches of Ram Inthra, Phahon Yothin, Vibhavadi Rangsit (outbound), Lat Phrao, Ramkhamhaeng, On Nut and Sukhumvit 71 near Khlong Tan.

Speaking at Don Mueang airport on 27 September, Governor Chadchart Sittipunt said flooding had begun to ease as the low-pressure system moved towards Myanmar. Inner-city areas including Ekkamai were beginning to dry, he said, while Bang Kapi, On Nut and Ramkhamhaeng remained a concern. Main roads could take two to three days to improve, and some communities around two weeks to dry out completely.

Beyond Bangkok, Thailand’s Department of Disaster Prevention and Mitigation reported flooding in 25 provinces as of 6am on 27 September, with eight deaths in Sa Kaeo, Chanthaburi and Saraburi.

Airports: open, but allow extra time to reach them

Suvarnabhumi (BKK) and Don Mueang (DMK) “remain open and operational”, the Tourism Authority of Thailand (TAT) said in its update at 6pm Bangkok time (4.30pm IST) on 27 September. The difficulty is getting to them.

Suvarnabhumi: TAT advises avoiding the Lat Krabang route because of significant waterlogging, and using Motorway No. 7 or the Burapha Withi Expressway instead. The airport asks passengers to allow at least three hours for international flights and two hours for domestic flights. The Airport Rail Link between the airport and central Bangkok is running.

Don Mueang: metered taxis at the airport are temporarily suspended. TAT says airport buses A1–A4 are running with some delays, with the pick-up and drop-off point moved to the Service Hall. The Don Muang Tollway gives direct road access to the terminals, and the Red Line commuter train from Krung Thep Aphiwat to Rangsit, which serves the airport, is running normally. The Thaiger, citing Airports of Thailand, reported that Grab ride-hailing was still available.

Flights, delays and baggage

We have not found reports of large-scale cancellations. Air traffic control authorities said flight operations were normal but some flights might be delayed, AP and Reuters reported. Thai Airways passengers at Suvarnabhumi faced departure delays and long waits for baggage on 26 and 27 September, which the airport attributed to flood-related shortages of ground-handling staff and faulty baggage carts. Passengers missing luggage are advised to file a delayed-baggage report with the airline.

Several Thai airlines are offering flight changes: Thai AirAsia, Nok Air, Thai Lion Air and Thai Vietjet for travel from 26 to 28 September, and Thai Airways for Suvarnabhumi departures from 26 to 29 September, each with its own conditions. We did not find flood-related change policies from IndiGo, Air India or Air India Express. If you are flying from India this week, check your flight’s status and your airline’s policy before you set off for the airport.

Getting around Bangkok, and trains out of it

TAT says the BTS Skytrain and MRT remain alternatives to the roads where there is congestion or local flooding; The Nation reported on 26 September that the MRT Blue, Purple, Yellow and Pink lines were running normally. We did not find a statement from the BTS operator. Both Red Line routes have resumed normal service.

Intercity trains, as of TAT’s 6pm update: State Railway of Thailand services on the Eastern Line are suspended; the Northern Line has reopened; the Northeastern Line is operating after an affected section reopened; and the Southern Line is running normally. On the morning of 27 September the railway had closed Eastern Line sections between Ban Kaeng and Sa Kaeo, and between Aranyaprathet and Watthana Nakhon. Check individual trains on the railway’s tracking service (ttsview.railway.co.th) or call 1690.

Monday and Tuesday, 28 and 29 September, are special holidays in Bangkok, Pathum Thani, Nonthaburi and Samut Prakan, approved by Thailand’s Cabinet on 27 September. Prime Minister Anutin Charnvirakul said they cover government agencies and the private sector. The city has also closed more than 400 of its schools on 28 September.

Hotels and sightseeing

TAT’s 6pm update says tourism services and visitor facilities across Bangkok continue to operate, although conditions vary by area. The flooded roads on the city’s list are mostly in the north and east. We have not found official reports of closures at major sights, but we could not confirm the status of individual attractions. Check with your hotel and any attraction before setting out, and allow extra time on the roads.

Weather outlook

The Thai Meteorological Department’s warning No. 16, issued on 27 September, says the low-pressure cell has moved to the western coast of Myanmar. It expects “less rain and isolated heavy rain” in Bangkok and vicinity, while heavy rain continues in parts of the North, the western Central region, the East and the upper South. Its seven-day forecast for Bangkok shows rain over 60% of the area on 28 September, 30% on 29 September and 40% on 30 September, rising to 60% on 1–3 October.

What Indian travellers should do

The Embassy of India in Bangkok had not posted a flood advisory on its website when we checked on the evening of 27 September; we did not check its social-media accounts. Its 24-hour emergency number is +66-618819218. The US Embassy issued a weather alert on 26 September advising its citizens to postpone non-essential travel in affected areas until the rain eases.

If you are due in Bangkok in the next few days: check your flight’s status with your airline, leave much earlier than usual for the airport, avoid the Lat Krabang route to Suvarnabhumi, and plan a way out of Don Mueang that does not rely on a metered taxi. Useful numbers in Thailand: TAT Contact Centre 1672, Tourist Police 1155, Bangkok city call centre 1555, emergency medical services 1669.
