TDAC and Connecting Flights: What Travellers Should Know
Travelling to Thailand via a connecting flight can be a convenient way to reach your destination, but it also requires careful planning, especially when it comes to the Thailand Digital Arrival Card (TDAC). Whether you're flying directly to Thailand or stopping over in another country, understanding how the TDAC applies to your journey is essential. This guide will help you navigate the process and ensure a smooth arrival experience.
What is the TDAC?
The Thailand Digital Arrival Card (TDAC) is a mandatory travel document required for most travellers entering Thailand. It streamlines the immigration process by allowing travellers to submit their details online before arrival. The TDAC must be submitted within three days before your arrival in Thailand, and it replaces the traditional paper arrival card.
Do You Need a TDAC for Connecting Flights?
If your journey involves a connecting flight, whether within Thailand or in another country, the need for a TDAC depends on your specific itinerary:
It’s important to verify your itinerary and confirm whether you will pass through immigration during your layover. For detailed guidance, check the official portal at https://tdac.immigration.go.th.
- Connecting flights outside Thailand: If you are transiting through another country and not entering Thailand during your layover, you do not need to submit a TDAC until your final flight to Thailand.
- Connecting flights within Thailand: If you are transferring through a Thai airport and will pass through immigration (e.g., collecting luggage or exiting the transit area), you must complete the TDAC before your initial arrival in Thailand.
How to Submit the TDAC for Connecting Flights
Submitting the TDAC for connecting flights is similar to the standard process, but timing is crucial. Here’s what you need to know:
- Timing: Submit your TDAC within three days before your arrival in Thailand. If you have multiple flights, base your submission on the date you first enter Thailand.
- Details: Ensure all information on your TDAC matches your travel documents, including your flight details and passport information.
- Proof: Once submitted, you’ll receive a confirmation QR code. Keep this accessible, as you may need to present it during immigration.
Common Questions About TDAC and Connecting Flights
Travellers often have questions about how the TDAC applies to connecting flights. Here are some of the most frequently asked questions:
1. Do I need a TDAC if I’m only transiting through Thailand? If you are transiting through a Thai airport without passing through immigration (e.g., staying in the international transit area), you do not need to submit a TDAC. However, if you plan to leave the transit area or collect luggage, you must complete the TDAC before arrival.
2. Can I submit the TDAC for both legs of my journey? No, the TDAC is only required for your arrival in Thailand. If your connecting flight is in another country, you do not need to submit a TDAC until your final flight to Thailand.
3. What happens if I miss the TDAC submission window? Failure to submit the TDAC within the three-day window before arrival may result in delays or denial of entry. To avoid complications, ensure you complete the process on time.
