Air Premia and Jeju Air have launched a new transpacific interline partnership, connecting U.S. cities to South Korea and regional Asian networks.
Long-haul passenger connectivity between North America and the Far East has been upgraded through a new airline alliance. Air Premia and low-cost carrier Jeju Air have launched an expanded interline partnership, allowing passengers to book single-ticket connecting flights from major United States cities to destinations across South Korea and regional Asian networks.
The partnership, which officially began on August 1, 2026, combines Air Premia's long-haul fleet with Jeju Air's domestic and short-haul international network, simplifying check-in procedures and improving flight options.

Connecting flight segments require coordinated schedules and terminal handling. The following table provides the long-haul origins, transfer hubs, regional connections, and baggage handling protocols under the new agreement.

Traveler Logistics and Incheon Airport Transit Guide
From a ground-level perspective, the best way to navigate this is to ensure at least a two-hour transfer window at Seoul Incheon (ICN) when connecting from Air Premia to Jeju Air, as transit security checkpoints can become congested during morning arrival banks. Travelers should check entry rules and transit visa codes.
To plan your connecting itinerary:
- Terminal Transfer Procedures: Air Premia and Jeju Air operate primarily from Terminal 1 at Incheon (ICN). Check your boarding pass for gate assignments, and follow terminal signs to the international transfer desks.
- Baggage Policies: Checked bags are transferred automatically on international-to-international routes. However, if your itinerary includes a domestic sector in South Korea (e.g., to Jeju or Busan), you must collect your bags, clear customs, and re-check them for the domestic flight.
- K-ETA Border Clearances: Travelers exiting the transit zone to enter South Korea during a layover must pre-register for a Korea Electronic Travel Authorization (K-ETA) online at least 72 hours before flight departure.
- Air Premia Checked Weight allowances: Air Premia’s checked baggage allowances apply to the entire interline booking, helping passengers avoid extra bag charges when switching flights.
Aviation Market Growth and Regional Access
The interline agreement strengthens both airlines' positions in the transpacific travel corridor. Air Premia can market flights to secondary Asian cities, while Jeju Air benefits from passenger connections arriving from major U.S. gateways including Los Angeles, Newark, San Francisco, Honolulu, and Washington Dulles.
For passengers, the single-ticket booking option provides consumer protections in case of delays or missed connections, as the operating airlines must arrange alternative flights. Rebuilding regional connectivity supports business travel and tourism corridors between the United States and growing markets in Japan, Taiwan, China, Southeast Asia, and domestic hubs in South Korea.
