Thai Airways

Thai Airways is Thailand’s flag carrier, one of five founding members of Star Alliance, and the dominant full-service airline out of Bangkok’s Suvarnabhumi Airport. It emerged from a court-supervised restructuring in 2024–2025 with its Thai Smile subsidiary folded back into the mainline fleet and a simplified route network. This page covers cabin classes, baggage allowance, and where the route network actually reaches.

Who Should Fly Thai Airways

• Travelers wanting a single-hub connection through Southeast Asia. Star Alliance reciprocity across partner airlines (United, Lufthansa, ANA, Singapore Airlines) makes status matching and lounge access straightforward on itineraries connecting through Suvarnabhumi.
• Travelers heading to Bali on a nonstop ticket. Thai Airways flies Bangkok–Denpasar nonstop, one of relatively few full-service carriers that do, avoiding a connection through Singapore or Jakarta.
• Travelers curious about a rare first-class product. Royal First survives on just three Boeing 777-300ERs and is being phased out, worth booking deliberately before it disappears, not something to expect on a random long-haul routing.
• Travelers flying within Thailand. With Thai Smile fully absorbed since January 2024, domestic connections now run on the same Thai Airways ticket and loyalty account rather than a separate regional brand.

Routes and Hubs

Thai Airways operates a single hub, Suvarnabhumi Airport (BKK), for its full international and domestic network; the airline’s former secondary brand, Thai Smile, was fully merged into mainline operations in January 2024. From Bangkok, the network reaches Europe, Australia, and major Asian hubs on widebody aircraft, plus a domestic network flown mostly on the Airbus A320s inherited from Thai Smile. Singapore and Bali are both flown nonstop from Bangkok. Both routes are shown in the chart below. Japan is served nonstop to both Tokyo and Osaka.

The Fleet

Thai Airways’ fleet is transitioning as older aircraft roll off and Airbus A350s take on more of the long-haul flying. Aircraft type is tied to route length and cabin configuration, and only a small handful of aircraft still carry the airline’s rare first-class cabin.

Cabin Classes

Thai Airways flies four cabins, but Royal First is the exception rather than the rule. It survives on only three Boeing 777-300ERs (registrations HS-TTA, HS-TTB, HS-TTC) and is set to disappear entirely once the airline’s new Business Plus suites launch in 2027. Which premium cabin is actually onboard depends on the aircraft assigned to a route, not just the fare paid.

Fares and Flexibility

Within Economy, Thai Airways sells several named fare levels, and the main thing that separates them is not the seat. It’s how freely you can change or refund the ticket, and how much baggage is bundled in. Saver is the cheapest way to book a confirmed seat; Flexi and Full Flex trade a higher price for more freedom to change plans.

Baggage Allowance

Thai Airways fully switched from a weight-based to a piece-based checked baggage system on March 2, 2026. Tickets booked before that date may still carry the old weight-based allowance printed on them, so check what’s on your own ticket rather than assuming the current rule applies retroactively. Here’s the shape of both carry-on and checked baggage under the current system:

Need more than the free allowance? Excess baggage can be prepaid online before departure at a lower rate than paying at the airport, with the exact per-bag fee set by route and cabin. Royal Orchid Plus Gold and Platinum members get one extra bag on top of the regular allowance in any cabin. The only number worth trusting is the one for a specific booking. Check the official checked baggage page before flying.

Sports equipment and oversized items (surfboards, golf clubs, dive gear) are accepted but must be declared in advance rather than sorted out at check-in; the fee varies by item and route, but the advance-declare requirement doesn’t.

Check-in and at the Airport

Thai Airways opens online check-in 24 hours before departure and keeps it open until 1 hour before the flight; airport counters at Suvarnabhumi open 8 hours out (unusually early for a full-service carrier) and close 50 minutes before departure. Here’s how the countdown to departure runs at the airport:

In-Flight Experience

Thai Airways builds its in-flight service around Thai hospitality and cuisine, with meal service reflecting the airline’s home cuisine alongside international options. The seatback entertainment system carries a large library of movies, TV, and music on long-haul aircraft, and wifi is available on most widebody aircraft, priced per flight or per day. Royal Silk and Royal First passengers get a wider choice of dishes and priority meal service.

Traveling with Children, Pets, and Special Needs

The policies that catch travelers out are the ones specific to who, or what, is flying with you. Here’s how Thai Airways handles the common cases; arrange any of them when you book rather than at the airport.

• Infants. Bassinet bulkhead seats can be requested for lap-infant bookings, and strollers can be gate-checked. Special baby meals can be pre-ordered through Thai Airways’ special meal request process.
• Unaccompanied minors. Children aged 5–11 flying alone must use Thai Airways’ mandatory Unaccompanied Minor service; those 12–17 can opt in. In Royal Silk or Royal First, the service is limited to children 8–11. Children under 5 may not travel alone under any circumstances.
• Special meals. Halal, vegetarian, dietary, and baby meals can all be pre-ordered, ideally 24–48 hours before departure. Halal is available on request, not an automatic default, except on flights to Pakistan where it’s served automatically.
• Pets. Thai Airways does not carry pets in the cabin; the only exception is a trained service dog traveling with a passenger with a disability. Cats and dogs at least 4 months old can travel as checked baggage (AVIH) on most routes, though this isn’t offered on flights to Auckland, Denpasar, Dubai, or Hong Kong; those routes require a separate cargo booking instead.
• Reduced mobility. Wheelchair and special-assistance requests can be arranged in advance through Thai Airways or your booking channel.

Loyalty Program

Royal Orchid Plus is Thai Airways’ frequent flyer program, with status built on a single points currency, Qualifying Miles, earned from flying Thai Airways or any Star Alliance partner. Member, Silver, Gold, and Platinum are the four published tiers, and Gold status carries Star Alliance Gold recognition across every alliance partner; Platinum is the outlier, requiring the miles to come specifically from paid Royal First or Royal Silk travel rather than any cabin.

Royal Orchid Plus miles can also be earned through hotel programs including IHG One Rewards, World of Hyatt, and Marriott Bonvoy, converting hotel stays into flight miles without booking a Thai Airways ticket directly.
