Southwest Adds Air Premia as New Transpacific Partner

‍DALLAS — Southwest Airlines (WN) has announced a new partnership with South Korea’s Air Premia (YP), expanding the U.S. carrier’s international connectivity through three transpacific gateways.

The partnership will allow travelers to connect between Southwest and Air Premia itineraries through Los Angeles International Airport (LAX), San Francisco International Airport (SFO), and Honolulu Daniel K. Inouye International Airport (HNL).

Southwest announced the agreement on social media, saying the partnership is intended to give customers more choices and “new horizons” through Air Premia’s transpacific network.

A Wider International Strategy

The Air Premia agreement is the latest step in Southwest’s move to broaden its global reach through airline partnerships rather than its own long-haul flying.

Southwest has historically operated a largely domestic and near-international network built around Boeing 737 aircraft. That model gives the carrier broad U.S. coverage but limits its ability to serve long-haul international markets directly.

Partnerships help close that gap. By linking its domestic network to international carriers at major gateway airports, Southwest can offer customers access to long-haul destinations without adding widebody aircraft or changing its core fleet strategy.

Air Premia, based at Seoul Incheon International Airport (ICN), operates long-haul Boeing 787 services and has built its business around a hybrid model offering transpacific flying at a lower cost structure than traditional full-service network carriers.

Three Gateway Airports

The initial connection points are Los Angeles, San Francisco, and Honolulu.

Los Angeles and San Francisco are natural West Coast gateways for transpacific travel, while Honolulu gives the partnership a Pacific connection point that aligns with Southwest’s existing Hawaii network.

For Air Premia, the agreement expands its U.S. sales reach by connecting its long-haul flights with Southwest’s domestic network. For Southwest, it adds another way to participate in Asia-bound travel without operating its own long-haul aircraft.

The partnership follows Southwest’s broader effort to add international connectivity through selected airline partners, including earlier agreements with Icelandair and China Airlines.

The Air Premia tie-up does not turn Southwest into a global network carrier. But it does show a clear change in strategy: Southwest is increasingly willing to use partnerships to extend the usefulness of its domestic network beyond the markets it can serve with its own aircraft.
