Thirty baht gets you from Suvarnabhumi toward Don Mueang and northern Bangkok
BMTA Airport Bus 555 runs from Suvarnabhumi’s Main terminal toward Don Mueang (DMK) and northern suburbs for roughly 30–35 THB, making it one of the absolute cheapest surface links out of BKK. It is a normal city/highway bus, not a point‑to‑point airport coach, and riders report it feels like a commuter line that just happens to hit both airports.
The ride between BKK and DMK commonly takes 90–120 minutes in Bangkok traffic, and Reddit posters regularly warn that 555 is a bad idea for tight airport transfers. One traveller said their airport‑to‑airport ride “took almost 2 hours in bad traffic, never again,” which lines up with reports that it can crawl once it hits congested stretches of tollway and local roads.
Frequency runs around every 20–30 minutes by user observation, with no tight timetable and occasional gaps longer than half an hour during off‑peak. The bus stops multiple times along the route, so even if you board quickly at Suvarnabhumi, expect intermediate pickups and drop‑offs before you get near Don Mueang or the northern suburbs.
Fares are paid on board in cash in Thai baht, and riders quote prices “on the order of 30–35 THB” for a through ride between BKK and DMK. There is no free airport‑to‑airport transfer anymore, despite older blog posts still calling 555 a free shuttle, and that mismatch is a frequent complaint in r/ThailandTourism threads.
Luggage handling is basic: no underfloor bays and no racks, so big 23 kg suitcases end up in the aisle or on your lap. Regulars on TripAdvisor and Reddit mention cramped seating with rush‑hour commuters, which can feel awkward if you board with two large bags and a backpack while locals are standing.
Locals say they only use 555 when they have several hours to burn or live along its highway route toward northern Bangkok. Some riders exit early at major junctions, then switch to faster options like the DMK A1/A2 airport buses or commuter vans to shave 20–30 minutes off the total time versus staying on 555 to the end.
Step-by-step from Suvarnabhumi (Main terminal)
- 1. Land at BKK and exit into the arrivals hall on Level 2 of the Main terminal, then follow signs up to the transport level on Level 1 within 5–10 minutes.
- 2. Walk toward the public bus area at the far end of Level 1 (look for BMTA signage); allow 5 minutes from the central arrivals zone to reach the bus bays.
- 3. Find the stop marked for route 555; if in doubt, show “Bus 555 to DMK?” to the BMTA staff at the stand and confirm you are heading toward Don Mueang, not just a partial route.
- 4. Board the next 555, grab any open seat, and keep large bags close; riders report that standing is common once the bus fills along the tollway.
- 5. Pay the conductor on board in cash shortly after departure; have at least 40 THB in small notes or coins ready for a full BKK–DMK ride.
- 6. Watch the time: if traffic is heavy and you hit the 60‑minute mark without being near DMK, start planning a backup if your connection is inside 3 hours.
- 7. Alight at Don Mueang when the bus announces or clearly pulls into the DMK area, then walk 5–10 minutes following “Passenger Terminal” signs to reach the terminal doors.
Practical tip: if your BKK–DMK connection is under 4 hours gate to gate, skip 555 and pay for a taxi or faster bus/rail combo instead; save route 555 for long layovers or when 30–35 THB really matters.
