International through‑check‑in service: One‑ticket‑through and checked‑baggage‑through

International transfer passengers can obtain boarding passes for both their international and domestic flight segments at the check‑in counter of their origin airport, with their luggage checked through to the final destination.

On January 9, Hainan Airlines flight HU782 (Vienna‑Chengdu TFU) landed at Chengdu Tianfu International Airport (TFU). Twelve passengers traveling onward to Beijing, Shenzhen, Sanya, and other destinations used the dedicated international‑to‑domestic transfer corridor to reach their domestic departure gates, completing the entire process in just 25 minutes. The inbound customs clearance procedures for the checked luggage of these passengers were fully delegated to and handled by the airline, with the bags transported directly to the cargo holds of their next flights. This marks the official launch of Hainan Airlines' international through‑check‑in service. It not only fills the gap in through‑service between Chengdu and Central &Eastern Europe but also establishes an efficient air corridor connecting China's western inland regions with the European hinterland.

An international through‑check‑in flight service is an operational model where international transfer passengers can receive boarding passes for both their international and domestic flight segments at the check‑in counter of their origin airport, with their luggage checked through to their final destination. This model achieves "one‑ticket‑through and checked‑baggage‑through", significantly optimizing the transfer process.

A relevant official from the ground services department at Chengdu Tianfu International Airport stated that with Hainan Airlines launching international through‑check‑in services on both its inbound Vienna‑TFU and outbound TFU‑Vienna flights, passengers are now provided with a seamless transfer experience featuring "one‑time security check, worry‑free journey". A relevant official from Chengdu Shuangliu International Airport Customs, which is under the Chengdu Customs District, explained, "We comprehensively gather feedback and suggestions from airlines and passengers regarding transfer facilitation. We currently provide end‑to‑end support and coordination for new international through‑check‑in flight services to help airlines meet corresponding regulatory compliance requirements. Simultaneously, via the through‑check‑in flight data‑sharing platform, we maintain real‑time information exchange with airport operators, airlines, and other relevant entities to ensure the orderly operation of through‑check‑in flights."

International through‑check‑in flights serve as a crucial lever for elevating an airport's hub competitiveness. To date, Chengdu Tianfu International Airport has launched 38 international through‑check‑in flight services, doubling the number since late 2024. These services now connect to key cities across Asia, Europe, the Americas, and Oceania, injecting robust momentum into Chengdu's development as an international aviation hub. An official from the Chengdu Municipal Port and Logistics Office reported that in 2025, Chengdu Tianfu International Airport processed 410,000 international through-check-in services, registering a year-on-year increase of 109 percent.
