Thai Airways Online Web Check-In: Everything You Should Know

Thai Airways Web Check-In is a digital service that lets travellers confirm their bookings, select seats and generate their boarding passes online, all from the comfort of home.
Instead of queuing at airport counters, passengers can check in via their laptop, tablet or smartphone in just a few clicks. The service is designed around one goal: convenience.

It’s perfect for those who prefer to travel smart, saving time, avoiding crowds and arriving at the airport ready to fly. Once you’ve completed your web check-in, your boarding pass is ready to download, print or store digitally on your phone.

Here’s why travellers love it:

• Skip the queues and check in wherever you are, at home, the office or even on the move.
• Choose your favourite seat ahead of time.
• Keep your boarding pass on your phone for quick access.
• Spend less time waiting and more time calming before takeoff.
• Start your trip with peace of mind and zero airport stress.

With Thai Airways Web Check-In, you’re not just checking in, you’re checking out of the chaos.

Timing matters when it comes to smooth air travel. Thai Airways Web Check-In operates within specific windows, depending on how you choose to check in and the type of flight you’re taking.

If you’re completing Thai Airways online check-in, you can do so starting 12 hours before your flight and it closes 2 hours before departure. That’s your golden window to secure your seat, confirm your booking and avoid last-minute stress.

For travellers who prefer using self-check-in kiosks at the airport, those open 48 hours before your flight and remain available until 90 minutes before takeoff. They’re quick, touch-screen easy and ideal for tech-savvy flyers.

If you prefer the traditional method, airport counter check-in opens 3 to 4 hours before your flight and closes 60 minutes before international and 45 minutes before domestic departures. For best results, plan to arrive 3–4 hours early for international and 2 hours 

Pro Tip: Even if you’ve completed web check-in, remember to drop your baggage at least 60 minutes before an international flight or 45 minutes before a domestic one to avoid any last-minute rush.

• You’re flying with pets or special cargo that needs manual verification.
• You’re part of a group booking or complex itinerary requiring document checks.

• Booking Reference Not Working: Double-check that your booking code and last name match your ticket exactly.

If the issue persists, simply use a self-check-in kiosk at the airport or head to the counter for quick assistance.
