How Early to Arrive at Don Mueang Airport (Domestic & International Flights)

Don Mueang International Airport (DMK) is one of two airports in Bangkok. This airport primarily serves low-cost carriers flying to domestic and international destinations.

I recommend arriving at Don Mueang Airport at least 2 hours before a domestic flight and 3 hours before an international flight.

To accommodate its 40 million passengers annually, Don Mueang Airport has two terminals:

• Terminal 1 for domestic flights (flights within Thailand)
• Terminal 2 for international flights (flights outside of Thailand).

When to Arrive at Don Mueang Airport?

You should arrive at Don Mueang Airport at least two hours before a domestic flight or three hours before an international flight. This should give you enough time to:

• Arrive at the airport
• Check-in for your flight
• Drop your bags
• Clear security
• Walk to your gate

Why Do You Need Longer for International Flights?

You should arrive at Don Mueang Airport at least 3 hours before an international flight (outside Thailand). This extra time is required for several reasons, including:

• Visa checks (where applicable)
• Entry requirements (where applicable)
• Immigration control
• Customs

Some international flights also often have a longer boarding period. Especially on larger planes where it takes more time for all passengers to board.

Other Factors to Consider When Flying From Don Mueang

There are four other factors you’ll want to consider when flying from Don Mueang Airport:

1. How you’re getting to the airport: Bangkok is notorious for its traffic congestion. If you’re travelling from Bangkok to Don Mueang by road, be sure to account for potential traffic delays.
2. The time of year you’re travelling: Allow extra time if you’re travelling over major holidays such as Songkran or Loi Krathong.
3. Checking in for your flight: Allow extra time if you need to check in in person at the airport rather than online.
4. Dropping off bags: Allow extra time at the airport if you have checked luggage. Most bag drop locations close one hour before the flight’s departure (exact times vary).
