Thai Airways allows passengers to use miles to upgrade their seats under the Royal Orchid Plus program. Depending on your ticket type and route, upgrades may be available for:
Economy Class → Premium Economy or Business Class
Business Class → Royal Silk Class or First Class
International routes to Europe, Asia, and the Americas
It’s important to note that not all fare classes are eligible for upgrades. To verify your ticket’s eligibility and confirm mileage requirements, calling +1-844-503-2111 ensures accurate and up-to-date information.
Before attempting an upgrade, ensure you have sufficient miles in your Royal Orchid Plus account. You can check your balance:
Online via the Thai Airways website
Thai Airways mobile app
By calling +1-844-503-2111
Having a clear understanding of your available miles will help you determine which routes and classes you can upgrade.
Not every ticket qualifies for mileage upgrades. Fare classes like Economy Discount or Basic Economy may not be eligible, while flexible fares usually are. To check if your ticket is upgradeable:
Review your booking confirmation for fare class codes
Check the Thai Airways website under Royal Orchid Plus upgrades
Or call +1-844-503-2111 to confirm eligibility
Agents can verify your ticket and explain exactly how many miles are needed for the upgrade.
Thai Airways sets the number of miles required based on:
Route distance
Original class of service
Destination and demand
Using miles efficiently is crucial. For example, upgrading from Economy to Business on a long-haul international flight may require more miles than a short regional trip. To get precise mileage requirements for your specific flight, call +1-844-503-2111.
