Uni Air

Uni Air, operating under the IATA code B7 and ICAO code UIA, is a Taiwanese airline that has established itself as a prominent carrier within the domestic and regional aviation landscape of Taiwan. The airline was formed in 1998 through the merger of two earlier domestic operators, Taiwan Airlines and Great China Airlines, consolidating their networks and assets to create a stronger, more efficient entity. Uni Air is a wholly owned subsidiary of the EVA Air Group, which itself is part of the larger Evergreen Group, a Taiwanese conglomerate with deep roots in maritime shipping and transportation. This ownership structure provides Uni Air with significant financial stability and operational synergies, allowing it to leverage the group's extensive aviation expertise and resources. Headquartered in Taipei, the airline was established with the primary mission of connecting Taiwan’s major cities and islands, serving as a vital link for business and leisure travellers across the nation.

The airline’s fleet is carefully tailored to the demands of high-frequency, short-to-medium-haul operations. Uni Air operates a modern and efficient mix of aircraft, predominantly the ATR 72-600 turboprop, a type ideal for shorter sectors and smaller airports, and the Airbus A321-200, a narrow-body jet suited for longer domestic routes and regional international flights. The ATR 72-600s form the backbone of the airline’s domestic network, prized for their fuel efficiency and ability to operate from runways with limited length. Meanwhile, the A321s offer greater capacity and range, supporting service on busier trunk routes. Over the years, Uni Air has progressively phased out older types such as the MD-90 and the Dash 8, concentrating on a streamlined two-type fleet to improve maintenance efficiency and crew flexibility. All aircraft are configured in a single-class layout with a focus on passenger comfort, featuring leather seats and generous legroom relative to the sector lengths.

Uni Air’s primary operational base is Taipei Songshan Airport, a city-centre airport that serves as the airline’s main hub for domestic services across the island and to outlying islands. The carrier also maintains significant focus operations at Kaohsiung International Airport in southern Taiwan and at Taichung International Airport in the central region, allowing it to offer a comprehensive domestic network that covers all major population centres and key island destinations. These airports function as focal points for the airline’s schedules, which are designed to provide frequent, reliable connections throughout the day. While the airline operates a full-service business model on domestic sectors, it does not belong to any global airline alliance. Instead, it benefits from code-share agreements and close coordination with its parent company, EVA Air, enabling seamless connections for passengers travelling beyond Taiwan to international destinations via the group’s larger network.

As Taiwan’s largest domestic carrier by passenger numbers and flight frequency, Uni Air has achieved several notable milestones. It has consistently been recognised for its operational safety and punctuality, maintaining a strong safety record that reflects the rigorous standards of the EVA Air Group. The airline has also invested in modernising its fleet and enhancing customer service, introducing self-check-in kiosks and mobile applications to streamline the travel experience. A significant achievement was the successful integration of its predecessor airlines, creating a unified brand with a reputation for reliability. Over the years, Uni Air has expanded its regional footprint by launching services to select East Asian destinations, further cementing its role as a key player in Taiwan’s aviation ecosystem. Its commitment to connecting Taiwan’s islands and cities, combined with its affiliation with a major global aviation group, ensures it remains a vital transportation pillar for the country.
