Seattle to Taipei in business.
Seattle to Taipei has emerged as Sea-Tac's top Asian international market, recently overtaking older routes as Taiwan's importance as a semiconductor manufacturing hub and a preferred transit alternative bypassing mainland Chinese airspace has grown. Four carriers now compete directly on the route — EVA Air, Delta, China Airlines, and STARLUX — a level of competition that keeps fares comparatively reasonable for the distance. This listing features Delta's Delta One service and EVA Air's award-winning Royal Laurel business class, widely regarded as one of the strongest premium products in the Asia-Pacific region: a true lie-flat seat with 71 inches of pitch, 26 inches of width, and a 6.5-foot bed length when reclined, each with its own entertainment system and reading lamps. Scheduled flight time runs approximately 10 hours 30 minutes outbound on EVA Air's Boeing 787-10, with the return typically taking closer to 11 hours 15 minutes. The route serves both Seattle's deep technology-sector ties to Taiwan's hardware industry and a substantial leisure and VFR market.
