Thai Airways Secures BOI Approval for Eight 787 Leases

Thai Airways Fleet Expansion

The Thailand Board of Investment (BOI) has officially approved two aircraft lease projects for Thai Airways International, totaling THB 14.3 billion (approximately $430.2 million). This strategic investment approval, detailed in the Thailand Board of Investment's recent infrastructure announcement, authorizes the carrier to lease eight Boeing 787 widebody aircraft to bolster its international network. The project is part of a broader $1.99 billion national investment package aimed at enhancing Thailand's global connectivity and industrial infrastructure.

Fleet Composition and Lease Terms

The approved lease agreement covers two distinct variants of the Dreamliner family. According to Thai Airways executive leadership, the airline will acquire five used Boeing 787-8 aircraft on operating leases of approximately six years. These units are reportedly sourced via Avolon to address immediate capacity requirements. Additionally, the carrier will secure three new Boeing 787-9 aircraft on longer-term 12-year lease contracts.

Strategic Industry Context

The approval marks a significant milestone in the airline's post-restructuring trajectory. In 2021, the carrier initiated a comprehensive debt restructuring plan to manage approximately THB 400 billion in liabilities. The current state-backed fleet expansion signals institutional confidence in the airline's rehabilitation. However, some financial analysts have expressed concern regarding the carrier's continued reliance on government-backed capital expenditures, noting that large-scale procurement may impact long-term financial self-sufficiency.

The Shift to Secondary Market Leasing

Thai Airways is utilizing a dual-track procurement strategy to navigate current supply chain constraints. By integrating used 787-8 airframes—reportedly ex-China Southern units—the airline can bridge capacity gaps while awaiting the delivery of new-build 787-9 aircraft. This approach reflects a broader trend among Asian carriers, which are increasingly turning to the secondary market to meet rebounding demand for long-haul international travel as OEM (Original Equipment Manufacturer) delivery timelines remain extended.

What Comes Next: Delivery and Service Timeline

The integration of these eight aircraft is scheduled to occur in phases throughout the remainder of the year. The five used Boeing 787-8 units are expected to enter service during 2026. Following these additions, the three new Boeing 787-9 aircraft are slated for entry into service between Q3 and early Q4 2026.

Why This Matters for Regional Connectivity

For Thai Airways, these lease projects provide the necessary widebody capacity to compete effectively on high-demand international routes. The move is not only an operational necessity for the airline but also serves as a pillar for the Thai government’s broader economic strategy. By securing these assets now, the carrier positions itself to capture growth in the recovering Southeast Asian aviation market while maintaining a manageable capital expenditure profile through the use of operating leases.
