EVA Air and Southwest Airlines have entered a new interline agreement effective immediately, the carriers announced on Tuesday.
The partnership will connect EVA Air passengers in four key cities, including Los Angeles (LAX), San Francisco (SFO), Seattle (SEA) and Chicago (ORD), with other cities across the U.S. via Southwest's expanding network.
Allowing for more seamless travel between Asia and North America, the agreement means that passengers can now book a single itinerary—including flights operated by both carriers—with coordinated ticketing and through-checked baggage service to their final destination.
What's more, passengers will receive boarding passes for all segments of their journey at the first point of departure, making connections more straightforward and efficient, the airlines promised.
"This partnership positions EVA Air for long-term growth in an evolving market by combining resources with Southwest Airlines," EVA Air America Head Office Executive Vice President Andrew Su said in a statement.
"Together, we're streamlining operations, connecting with a broader range of travelers, and responding more swiftly to changing market needs," he added. "Beyond simply adding flight options, we are dedicated to reimagining how we serve our passengers and providing travel experiences that are more personalized, more flexible, and thoughtfully designed around their needs."
"Our relationship with EVA Air brings new opportunities for access between Asia and the United States through our unmatched domestic network," said Southwest Airlines Chief Operating Officer, Andrew Watterson. "We're grateful for this new partnership and the additional dimension it brings to our ongoing work to bring more choice in travel experiences with global reach."
EVA Air currently offers 89 weekly flights to major cities in the U.S. and Canada, with that number increasing to 94 weekly flights by the end of 2025.
