Spring Airlines Co., Ltd. (601021.SS): How It Works

• Fleet & network: Single-family narrowbody fleet (primarily Airbus A320/A321 variants) for simplified maintenance, crew training, and high seat density.
• Cost structure: Single-class cabin, no free onboard meals/beverages on most services, direct sales emphasis to avoid distribution fees - all designed to keep unit costs below legacy carriers.
• High utilization: Quick turnarounds and dense scheduling increase seat-mile production per aircraft and lower per-seat costs.

• Air ticket sales: Low base fare stimulates demand and yields high load factors; dynamic pricing + network density on domestic and regional routes.
• Ancillary services: Baggage upgrades, seat selection, onboard meals, and priority services sold à la carte increase PRASM (passenger revenue per available seat mile).
• Digital platform commissions: Spring diverts traffic from its website and app to third-party providers (hotels, car rentals, attractions), collecting commissions and referral fees.
• Non-airline businesses: Import/export of goods & technology, advertising on aircraft and digital properties, e-commerce tie-ins, training services, and leasing/rental activities add alternative revenue streams.

• Travel services: Hotel bookings, scenic spot entrance tickets, visa assistance, airport transfers.
• Onboard & ground upsells: Paid meals, extra baggage, preferred seating, priority boarding.
• Commercial partnerships: Advertising, brand-linkage campaigns, and aircraft/fuselage naming rights.

• March 2025 strategic cooperation with Shanghai Dingzhi Dental Co., Ltd.: includes fuselage naming, brand linkage, and integrated service offerings - an example of monetizing brand exposure and creating cross-selling opportunities between aviation and consumer services.

• Load factor: High load factors maximize revenue per flight given fixed-cost base.
• PRASM vs. CASM: Focus on increasing PRASM (ticket + ancillaries) while keeping CASM (cost per available seat mile) low via uniform fleet and streamlined operations.
• Direct sales penetration: Higher share of direct bookings reduces GDS/agent fees and increases margin on tickets and ancillary products.

Spring Airlines Co., Ltd. (601021.SS): How It Makes Money

• Ticket sales - primary source via point-to-point short- and medium-haul routes across China and Asia.
• Ancillary services - baggage fees, seat selection, priority boarding, in-flight sales and packaged services.
• Cargo and belly freight - incremental yield from cargo capacity on passenger aircraft, increasingly targeted on international routes.
• Charter and seasonal operations - ad hoc charters for tour operators and peak-season demand.
• Partnerships & codeshares - feed traffic and extend network reach without large capital outlay.

• Fleet & capacity strategy: steady fleet additions and route launches aimed at improving seat-mile yields and international market penetration across Asia, supporting the projected 9-12% revenue CAGR.
• Operational focus: tight cost control (unit cost leadership), high ancillaries penetration and punctuality-driven customer retention sustain margins even as competitors face losses.
