Thai Airways Baggage Policy 2025: Allowance, Rules, and Check-In Guide

Flying with Thai Airways International is always a graceful experience, offering elegant cabins, warm Thai hospitality, and a vast global network. But before you start packing, it’s important to know how much baggage you can bring.

From April 1, 2025, Thai Airways updated its baggage system, especially for Economy Class travelers. Saver and Standard fares now allow 23 kg of checked baggage instead of 25 kg, while premium passengers continue to enjoy higher limits. Knowing your Thai Airways baggage allowance beforehand helps you avoid last-minute fees and travel with confidence.

Overview of the Thai Airways International Baggage Policy

The Baggage Policy Thai Airways follows two main systems:

1. Weight Concept: Applied to most routes in Asia, Australia, New Zealand, Europe, the Middle East, and Africa.

2. Piece Concept: Applied only on flights to or from the USA and Canada.

Each passenger’s allowance depends on their travel class, route, and fare type. Here’s a quick overview:

Weight Concept: International Flights (Non-USA/Canada Routes)

• Saver and Standard fares allow 23 kg for tickets issued on/after April 1, 2025 (previously 25 kg). Flexi and Full Flex fares continue to allow 30 kg.

Frequent flyers enjoy even more:

• ROP Silver Members: +10 kg

• ROP & Star Alliance Gold Members: +20 kg

• Royal Orchid Platinum Members: +30 kg

So if you’re a loyal Thai Airways traveler, your total Thai Airways baggage allowance could easily exceed 50 kg in premium cabins.

Thai Airways Check-in Baggage Policy for USA/Canada Routes (Piece Concept)

If your flight includes North America, the Thai Airways check-in baggage policy switches to the piece system, a standard used by many transpacific airlines.

Royal Orchid Plus Gold and Platinum members are entitled to one extra piece beyond the regular limit, regardless of class.

This system makes it easy to plan if you’re traveling long-haul with multiple connections, but be mindful that other partner airlines may have different limits on code-share flights.

Thai Airways Domestic Baggage Policy

For journeys within Thailand, the Thai Airways domestic baggage policy uses the weight concept only.

• Saver and Standard fares offer 23 kg from April 1, 2025; Flexi and Full Flex remain 30 kg.

• Additional allowances also apply for frequent-flyer tiers, identical to international flights:

• ROP Silver (+10 kg), Gold (+20 kg), and Platinum (+30 kg).

Carry-on Baggage Allowance

Your cabin bag should fit easily in the overhead locker or under the seat in front of you. Thai Airways may conduct spot checks at the check-in or boarding to ensure all items meet the rules.

Carry-on limits by travel class:

Royal First Class or Royal Silk Class:

• Up to 2 pieces of cabin baggage

• Each piece must not exceed 7 kg

• Maximum size: 56 × 45 × 25 cm (including wheels, handles, and pockets)

Economy Plus or Economy Class:

• 1 piece of cabin baggage

• Weight limit: 7 kg

• Maximum size: 56 × 45 × 25 cm (including wheels, handles, and pockets)

Passengers may also carry:

• A handbag, purse, or laptop bag (up to 1.5 kg)

• Walking sticks or crutches, if required

• Infant food or essential medicines

Liquids and gels in cabin bags must follow international security rules:

• Containers must be 100 ml or less

• All containers must fit inside a clear, resealable plastic bag (up to 1 liter)

• The bag must be presented separately during security screening

By following these simple carry-on rules, you can enjoy a smoother and stress-free boarding experience with Thai Airways.

Excess Baggage and Online Pre-Purchase

If you exceed your free baggage allowance, you’ll need to pay extra. The rates depend on whether you’re traveling domestically or internationally:

Domestic Flights (Weight Concept):

Excess baggage is charged per kilogram, starting from around THB 55–80 per kg depending on route (e.g., Bangkok – Chiang Mai = THB 60 /kg; Bangkok – Phuket = THB 70 /kg).

International Flights (Weight Concept):

Charges are based on zones between USD 12 and USD 70 per kg, depending on the region (Asia, Europe, the Middle East, and Australia).

Tip: Buying excess baggage online through Thai Airways’ website before departure is cheaper than paying at the airport counter.

For flights involving the U.S. or Canada, excess baggage follows the piece-concept fee table, which varies by route and class.

Special Notes and Exceptions

• Code-share flights: If your journey includes a partner airline (especially U.S. segments), that carrier’s baggage rules may apply.

• Mixed-class tickets: If you fly partly in First Class and partly in Economy, the allowance for each sector follows the class paid for.

• Strollers: Foldable baby strollers are carried free of charge in the aircraft hold.

• Government or special agreements: Certain passengers traveling under government orders may have unique allowances stated on their tickets.
