How online check-in works
Online check-in is available through the Thai Smile website, typically opening 24 hours before departure. This service allows you to select seats, confirm passenger details, and receive your boarding pass digitally, reducing time spent at the airport.
- Visit https://www.thaiairways.com and navigate to the check-in section.
- Enter your booking reference (confirmation code) and passenger last name.
- Review and confirm your flight details and personal information.
- Select your seat if not already assigned and any available seat upgrades.
- Accept baggage declarations and any special conditions.
- Complete the check-in process and download or display your digital boarding pass.
Practical tip: Complete online check-in as early as possible after the 24-hour window opens to secure preferred seating and avoid last-minute airport queues, especially during peak travel times.
