(THAILAND) Thai Airways may slow or pause parts of its 2025 flight expansion after running into a global aircraft shortage and new delivery delays, forcing the carrier to reset timelines for routes and fleet growth. Senior executives say the shortfall is affecting the winter schedule and beyond, with knock-on effects for passengers who plan trips around visa dates, university start times, job relocations, and family reunions. The airline had mapped out ambitious expansion plans for 2025, but the industry-wide supply crunch and manufacturing bottlenecks are now dictating what it can realistically fly.
Delivery delays and operational impact
At Routes Asia 2025 on 25 March 2025, Thai Airways’ head of scheduling, Thiti Arayakhun, confirmed the carrier “cannot get the aircraft in time,” pointing to widebody delivery delays and the supply chain strain that continues across the sector. CEO Chai Eamsiri has echoed that message in public remarks, saying the delays are limiting how fast Thai can add flights, even as demand continues to recover. The essential problem is simple: planes that were expected this year are not arriving on schedule, and maintenance and parts pipelines remain tight.
These shortfalls are already influencing the winter schedule and may affect travelers who depend on precise arrival dates—students, contract workers, and families among them. When aircraft are late, routes can be delayed, frequencies pushed back, or capacity reallocated, creating cascading schedule changes across the network.
Fleet targets, interim solutions, and timelines
Thai Airways still aims to grow its fleet, but the timeline has shifted.
- Target fleet change: increase from 79 to 90 aircraft by end-2025 (dependent on actual arrivals).
- Leases secured: five Airbus A321neo, with deliveries beginning in 2025 and continuing into 2026 and 2027.
- Proposed interim measure: lease 8–10 widebody aircraft for six years to cover the gap and support immediate network growth.
- Decision on interim lease expected by September 2025.
Executives describe the interim lease as a bridge to keep key routes operating while waiting for permanent fleet arrivals.
Current fleet snapshot and long-term ambition
- Operated fleet as of Q1 2025: 78–85 aircraft
- Average fleet age: near 10 years
- Long-term target: 150 aircraft by 2033
The short-term numbers matter because they determine which routes can realistically be flown and when.
Winter 2025–26 schedule priorities
Thai is prioritizing markets and slots with strong demand and reliable yields.
Planned frequency changes for winter 2025–26:
– Double flights to Guangzhou and Beijing — from 7 to 14 weekly on each route.
– Resume service to Xiamen, Chongqing, and Changsha at 7 weekly each.
– Under study (contingent on aircraft): Wuhan, Shenzhen, and Gaya.
These moves concentrate scarce widebody capacity on routes with consistent demand and feed potential to the broader network.
Important: All new services and frequency increases are contingent on aircraft availability. When a single widebody is delayed, it can force changes across several routes.
Cabin upgrades and passenger experience
Despite delivery setbacks, Thai is investing in passenger experience.
- Announcement: Retrofit on 29 April 2025 for Boeing 777-300ERs and older Airbus A350-900s.
- New Royal Silk (business) and Economy seats.
- Launch of an Economy Plus cabin.
- Broader upgrade wave scheduled to start in 2027.
- Budget for cabin projects: 20 billion baht.
These upgrades aim to boost premium revenue potential and improve the on-board product while fleets roll out.
Financial position and investment plan
Thai Airways presents a stronger financial footing that supports its plans.
- Five-year investment plan (announced July 2025): 170 billion baht
- 120 billion baht for aircraft acquisitions
- 20 billion baht for cabin upgrades
- Cash reserves: rose from 22 billion baht (pre-rehabilitation) to 152 billion baht by Q1 2025.
- Debt-to-equity ratio: improved from 12.5 in 2019 to 2.2 in Q1 2025.
These improvements give Thai flexibility to pursue interim leases, direct acquisitions, or other financing options as the delivery pipeline clears.
Network strategy and constraints
Board Chairman Piyasawat Amaranan has said Thai is studying new long-haul options over the medium term, but flights to the United States 🇺🇸 are not part of the near-term plan due to aircraft scarcity.
Key strategic focuses:
– Prioritize Asian and European routes with high demand and better return profiles.
– Increase frequencies on existing city pairs where slots and demand align.
– Revisit long-haul expansion once aircraft deliveries and slot availability permit.
Industry constraints to note:
– Ongoing supply chain problems (parts, engine shop backlogs, training/certification bottlenecks).
– Tight slot availability at key airports, which can limit growth even when planes are available.
What this means for travelers
Operational limits have practical consequences. Travelers should prepare for potential schedule moves that could affect visa timing or key commitments.
Practical guidance:
– If a route launch slips or a schedule change pushes your arrival past a visa’s first-entry window, contact the airline and check official visa guidance before rebooking.
– Students and workers: plan a buffer around official start/registration dates.
– Tourists with fixed packages: confirm cancellation/change terms and check whether visa adjustments are required.
– Families attending reunions, weddings, or medical care: keep flexible options or consider alternate existing services.
VisaVerge.com analysis highlights that schedule changes can push travelers close to visa validity edges, sometimes forcing a new visa application or official date changes.

Wider impacts on the travel ecosystem
Employees and partners across the travel chain—ground handlers, catering, tourism firms, airport services—must plan around a moving delivery calendar. Thai’s prioritization of high-demand routes and premium segment growth aims to produce steadier revenue and protect jobs while capacity is constrained.
Key watch points and milestones
- Interim widebody leasing decision expected by September 2025.
- Delivery timing for leased A321neo aircraft (2025–2027) and any additional widebodies in 2026–2027.
- Rollout pace for winter schedule increases to China and timing for resumptions/launches to Wuhan, Shenzhen, and Gaya.
- Progress on cabin retrofits announced 29 April 2025, and the broader upgrade wave beginning 2027.
Long-term outlook for investors and partners
Thai’s long-term targets remain:
- Fleet: 150 aircraft by 2033
- Market share: 26% → 35% by 2029
- Premium cabin share: 0.5% (2024) → 10% by 2033
Financial and market milestones:
– Exit from rehabilitation: June 2025
– Resumption of trading on the Stock Exchange of Thailand: 4 August 2025
A stronger balance sheet and improved leverage give Thai optionality once the manufacturer pipeline loosens—potentially accelerating acquisitions or leases and enabling further route expansion.
Final takeaways for travelers, employees, and investors
- For travelers: stay flexible, verify visa windows after any flight change, and use official sources for immigration guidance.
- For employees and partners: expect prioritization of high-demand routes and premium segments to stabilize revenue and operations.
- For investors: Thai’s liquidity and improved leverage support its medium-to-long-term ambitions, but near-term growth is constrained by global supply and slot limits.
