Trinity Airways

Trinity Airways, established in 2003 as one of Korea's first low-cost carriers, provides passenger and cargo air transport, and changed its name from T'way Air to Trinity Airways after being acquired by Sono International (Sono Trinity Group) in 2025.

As of the end of March 2026 the company operated a fleet of 48 aircraft including A330, B777 and B737 types, flying domestic routes to Gimpo, Jeju, Daegu, Gwangju, Cheongju and Busan, and international routes across Asia, Europe, Oceania and the Americas.

Its subsidiary, Trinity Air Service, handles ground handling and reservation center operations.

The company has newly introduced an 'SSC (Selective Service Carrier)' strategy that differentiates pricing and service by route length, maintaining existing low fares on short-haul routes such as Japan and Southeast Asia while offering premium check-in, in-flight Wi-Fi and higher-quality meals on long-haul routes to the Americas and Europe, an attempt to move beyond its traditional LCC image.

This is interpreted as an effort to target higher-fare demand on mid- and long-haul routes, moving away from Korea's traditional binary structure of low-cost carriers versus full-service carriers.

The competitive landscape continues to feature existing LCCs such as Jeju Air, Air Busan and Jin Air on domestic and international routes, while route rights transferred from the Korean Air-Asiana Airlines merger add a new variable in building out mid- and long-haul networks.

The largest shareholder is Sono International, and synergies combining the group's leisure and lodging infrastructure with airline services are also being pursued.

On an annual basis, revenue rose from KRW 525.8 billion in 2022 (operating loss of KRW 103.9 billion, operating margin -19.8%) to KRW 1,348.8 billion in 2023, when the company posted an operating profit of KRW 139.4 billion (margin 10.3%), a clear swing to profitability.

However, 2024 reverted to an operating loss of KRW 12.3 billion (-0.8%), and in 2025, even as revenue grew further to KRW 1,798.2 billion, the operating loss widened to KRW 265.5 billion (-14.8%), with net loss attributable to owners reaching KRW 338.3 billion.

On a quarterly basis, the operating loss widened from KRW 78.3 billion in Q2 2025 to KRW 95.5 billion in Q3, before narrowing to KRW 56.2 billion in Q4.

In Q1 2026, revenue reached KRW 612.1 billion with an operating profit of KRW 19.2 billion, marking the first quarterly operating profit in roughly two years, but Q2 2026 saw revenue decline to KRW 469.7 billion while the operating loss ballooned to KRW 182.0 billion, a record quarterly loss.

This sharp reversal reflects a combination of rising fuel costs, currency pressure, and the initial costs of expanding mid- and long-haul routes.

Summing the most recent four quarters (Q3 2025 through Q2 2026), the net loss attributable to owners totals approximately KRW 443.5 billion, showing that the quarterly return to profit has not yet translated into a stable annual earnings structure.

Meanwhile, operating cash flow remained positive every year despite recurring net losses, though it has narrowed from KRW 415.3 billion in 2023 to KRW 272.4 billion in 2024 and KRW 171.1 billion in 2025.

Equity attributable to owners has continued to shrink, from KRW 157.1 billion in 2023 to KRW 82.3 billion in 2024 and KRW 52.0 billion in 2025, indicating an increasingly thin capital base.

Korea's LCC industry has expanded in scale as passenger demand recovered after the pandemic, but persistently high fuel prices and a strong dollar continue to pressure profitability across the sector.

Competitor Air Busan, for instance, saw revenue grow in Q2 2026 but still posted an operating loss, reflecting similar pressures. Korean Air, by contrast, has shown improving performance on strong cargo results, widening the gap in financial resilience among carriers.

The route rights transferred following the final approval of the Korean Air-Asiana Airlines merger have created an opportunity for LCCs including Trinity Airways to expand mid- and long-haul networks, and the company is reported to have benefited from rising load factors driven by increased Europe and Americas route revenue and connecting-transfer demand.

Near Incheon International Airport, large MRO facilities covering aircraft conversion and heavy maintenance are being built in succession, with both Korean Air and Trinity Airways separately pursuing their own hangar construction, intensifying competition to expand domestic maintenance infrastructure.

Trinity Airways' hangar is expected to become the first independently built maintenance facility among Korean LCCs, making the timing of its completion a point of industry attention given repeated delays.

Overall, while underlying passenger demand remains solid, the industry is entering a phase where cost structure and financial capacity are creating increasingly visible gaps between carriers.

The company plans to officially begin operations as Trinity Airways on September 10, 2026, deploying a newly liveried aircraft on the Gimpo-Jeju route, with existing aircraft to be repainted in the new design over time.

To improve its financial structure, the company carried out capital raises in 2025 including a KRW 110 billion rights offering and KRW 90 billion in perpetual bonds in August, followed by a KRW 191 billion package in December comprising a KRW 100 billion third-party allocation (with Sono International participating at no discount) and a KRW 91 billion rights offering.

These funds are earmarked for strengthening financial stability, improving operational stability, and securing new aircraft and materials, with plans to introduce five A330-900neo aircraft from 2026 and secure two Rolls-Royce Trent 7000-72 spare engines via sale-and-leaseback to reduce maintenance-related flight cancellations.

However, investment in the maintenance hangar at Incheon Airport's advanced aerospace complex, first decided in December 2024, has seen its construction start date postponed three times; the project now targets a December 2027 start and December 2029 completion, with total investment adjusted to KRW 136.5 billion.

Separately, the company carried out a 5-for-1 share consolidation in August 2026 (par value from KRW 100 to KRW 500), resuming trading with new shares listed on August 31.

The company has stated its intention to prioritize safety and trust while pursuing route diversification and cargo business expansion to build a structure generating stable revenue and cash flow.
