Mainline Flight Service

What Mainline Flight Service does

Mainline Flight Service (万里安飞行服务（上海）有限公司) is a Shanghai-based aviation services company founded in April 2015 that provides flight operations support to international and domestic airlines operating in China. The company offers four core service lines: operations support (dispatch, ground handling coordination, and flight planning) for foreign carriers entering or transiting the Chinese market; aircraft ferry and delivery services; charter and air ticket services for corporate and government clients; and fueling services delivered through a strategic alliance with ASM. The company also integrates an aeronautical and navigation database covering 30,000+ airports and 39,000+ runways via a 2024 partnership with Keyvan Aviation, and has begun positioning itself in the low-altitude economy and eVTOL services vertical.

Mainline operates a network comprising 2,000+ ground service agents, 3,000+ travel agency partners, 50+ airline clients, and 11 core hubs across 64+ airports, having serviced 2,000+ international flights to date. It holds IS-BAO, IS-BAH, and AS9100D certifications, is a SASAC-qualified supplier, and maintains a documented zero-penalty record — credentials that are effectively mandatory for handling international airline operations in China. Named customers include Cargojet, DHL Air, CMA CGM Air Cargo, Keyvan Aviation, Genghis Khan Airlines, and the Chinese Ministry of Foreign Affairs, alongside 200+ airline clients globally.

The business model is service-fee based, with revenue generated per flight, per route, or per service engagement rather than via software subscription or asset rental. The company is privately held and founder-controlled (Sun Hui / Hui Sun), has 28 employees, and has not disclosed any external funding rounds. As of early 2025, Mainline has begun a deliberate expansion into scheduled all-cargo services (via the Cargojet route authority and the CMA CGM partnership) and into advanced air mobility, including co-founding the Advanced Air Mobility Association of Shanghai Longhua.
