Can You Board Without TDAC? Thailand’s 2025 Airport Rules You Shouldn’t Ignore
One question you might have if you’re flying to Thailand in 2025 is, Can you board without TDAC? Understanding the Thailand Digital Arrival Card boarding requirement is essential whether you’re flying from Malaysia, Singapore, or Dubai. In regards to TDAC airline boarding and airport check-ins, travelers seek clear answers. We have broken it all down in an easy-to-follow, up-to-date guide.

Why Is TDAC Important?
A TDAC is an electronic arrival card issued by the Thailand Immigration Department. For all foreign travelers entering Thailand by air, TDAC has replaced the older TM6 paper form.
Within 72 hours before your arrival, you must submit it online at TDAC.
In this case, it applies to:
- International flights only
Important: TDAC is not a visa. It’s a separate requirement meant to streamline immigration.
Is it possible to board without TDAC?
Risky, but it depends.
While some airlines may allow boarding without a TDAC confirmation, many now check for it at airport check-in, especially for routes into Thailand.
Thai immigration will check even if the airline doesn’t. Arriving without a valid TDAC QR code may result in delays, fines, or even denial of entry.
If you’re wondering, “Do I need TDAC to board a flight?” – it’s safer to answer yes. When you have your TDAC ready, you can:
- Check-in is faster
- No last-minute airport stress
- An easy entry into Thailand
Since airlines don’t want to be liable for flying passengers without proper paperwork, many adopt TDAC airline boarding policies.
TDAC Airport Check-In Thailand
During airport check-in for flights to Thailand, especially in 2025, many airlines now ask for TDAC confirmation alongside your passport, visa, and ticket.
Here’s what you need to show:
- Passport
- Valid visa (if applicable)
- TDAC QR code (printed or on your phone)
Some airlines may not explicitly mention TDAC in their check-in requirements, but it’s becoming standard practice for major carriers flying into Thailand from hubs like Kuala Lumpur, Singapore, and Dubai.
