Skip the overpriced taxi scams — here’s how to get from Bangkok airport to the city for under $3 during rainy season.
First: Which Bangkok Airport Are You Landing At?
Suvarnabhumi (BKK) handles most international flights. Don Mueang (DMK) is the base for AirAsia, Thai Lion Air, and other budget carriers. These two airports sit about 45 minutes apart by road — if you land at the wrong one, you’re adding 600-800 THB and 90 minutes to your trip before you even start.
We tracked 12 ground transport providers in Bangkok to bring you these numbers.
What’s the Cheapest Way from Suvarnabhumi Airport?
Airport Rail Link — 45 THB (about $1.20) to downtown.
The Airport Rail Link runs from Suvarnabhumi to Phaya Thai station in 30 minutes flat. Trains run 06:00-midnight daily. A one-way ticket costs 45 THB for the express line, or you can take the older commuter train for just 15-45 THB depending on your destination.
From Phaya Thai, connect to the BTS Skytrain to reach most Sukhumvit-area hostels and hotels. Total cost: around 61-89 THB ($1.70-$2.50).
What’s the Cheapest Way from Don Mueang Airport?
A1/A2 Bus to BTS Mo Chit — 30 THB (under $1).
Don Mueang is actually friendlier to extreme budget travelers. Hop on the A1 bus (30 THB) from the airport and ride it to BTS Mo Chit station. From there, the BTS network covers most of the city. Total journey: under 50 THB if you’re strategic.
Is It True That Taxis Add Surcharges During Rainy Season?
Yes — and it can get bad. Prices jump 50-100% during storms.
Bangkok’s rainy season runs May through October, with afternoon downpours being the norm. The BMTA (Bangkok Mass Transit Authority) reported that taxi refusal rates spike roughly 40% higher during peak rainy season compared to dry months. During heavy storms, drivers simply don’t want to deal with flooded roads and slow traffic.
Our advice: Book through Grab before you land. The price is locked in — no surprises, no negotiations, no standing in the rain arguing.
Should Backpackers Just Use Public Transport?
Yes, if you’re not in a rush and traveling light.
Here’s the breakdown for budget-conscious travelers:
From Suvarnabhumi:
- Airport Rail Link to Phaya Thai (45 THB)
- BTS to your station (16-44 THB depending on zones)
- Total: 61-89 THB ($1.70-$2.50)
From Don Mueang:
- A1 bus to BTS Mo Chit (30 THB)
- BTS to your station (16-44 THB)
- Total: 46-74 THB ($1.30-$2.10)
The catch: you拖着行李走，有些站点没有电梯。雨天拖着大箱子走楼梯，体验很差。

What If My Flight Lands Late at Night?
Grab or pre-booked transfer — skip the airport taxi touts.
Airport Rail Link closes at midnight, and late-night taxi drivers in Bangkok are… a different breed. They add 50% surcharges legally, but often demand 2-3x the meter rate illegally. Not worth the headache.
For flights arriving after 23:00, budget around 400-600 THB for a Grab. Pre-booked private transfers from Welcome Pickups run 500-1200 THB depending on destination — higher upfront, but zero stress.
How Bad Is Traffic During Rainy Season?
Really bad. Add 40-60 minutes to road travel times.
Google Maps data shows that routes from Phaya Thai to Suvarnabhumi take 40-60 minutes longer during afternoon rain compared to dry conditions. If you have a 6 PM departure flight, don’t plan to leave your hostel at 4 PM. Leave by 2-3 PM instead to be safe.
On the bright side: Suvarnabhumi Airport has excellent facilities — free WiFi, air conditioning, plenty of food options, and comfortable seating. Arriving early is never boring.
Is a Private Transfer Worth It?
Only if you’re in a group or carrying heavy luggage.
At 300-1500 THB per trip, private transfers aren’t the cheapest option. But if you’re traveling with 3-4 people, the per-person cost (75-375 THB) becomes competitive with taxis — and you avoid the rain entirely.
For solo travelers with big backpacks: stick to public transport and wear a rain jacket. Save the splurge for a nicer hotel night instead.
FAQ
Q: Is there a free shuttle between Don Mueang and Suvarnabhumi airports? A: Yes — a free public bus runs between the two airports (05:00-24:00), taking 60-90 minutes. But don’t take it just to catch a transfer at the other airport. Only use it if you specifically need to switch airports.
Q: Do I need to tip taxi drivers in Bangkok? A: Not required, but rounding up is appreciated. For metered taxis, tip is not expected but common for good service.
Q: Can I use public transport immediately after getting my visa on arrival? A: Yes. Public transport doesn’t check visa status. Taxis sometimes use this as an excuse to overcharge — keep your route screenshots ready.
Q: What’s the worst time to travel by road in Bangkok during rainy season? A: 5-8 PM is peak chaos. Afternoon storms coincide with regular rush hour. Schedule airport pickups for morning or midday when possible.
Q: Can I get a taxi from Don Mueang at 3 AM? A: Yes, but you’ll likely pay a premium. Pre-book via Grab or your accommodation to lock in a fair price.
