EVA Air's Taipei Service Becomes Washington Dulles' Longest Non-Stop Route at About 7,800 Miles
Why It MattersUltra-long-haul routes from secondary US gateways let Asian carriers bypass Japanese and Korean hubs, shifting East Coast transpacific connecting traffic toward Taipei and reshaping how Washington-area travelers reach Asia-Pacific.
What happened
EVA Air's non-stop service between Washington Dulles International Airport and Taipei Taoyuan International Airport covers roughly 7,800 miles (12,552 km), making it the longest non-stop route from Dulles. The route is flown with a Boeing 787-9, with scheduled flight times well beyond 15 hours depending on direction and conditions.
The service operates four times weekly. Washington departures are on Tuesdays, Thursdays, Saturdays and Sundays; return flights leave Taipei on Mondays, Wednesdays, Fridays and Saturdays. It initially ran three times per week before increasing to four weekly flights in March. EVA Air announced the route in February 2026.
The aircraft has 278 seats in three classes: 26 Royal Laurel Class, 28 Premium Economy and 224 Economy. The Premium Economy cabin uses EVA Air's newer fourth-generation product.
US Bureau of Transportation Statistics data shows Dulles handled more than 10.5 million international passengers in 2025, with London Heathrow the busiest international destination at 817,000 passengers, followed by San Salvador (643,000), Frankfurt (629,000), Paris Charles de Gaulle (502,000) and Istanbul (357,000). EVA Air and the Metropolitan Washington Airports Authority estimate the route will generate more than $61 million in annual economic impact for the US National Capital Region; this is a projection, not a measured figure.
With Washington added, EVA Air has ten non-stop North American gateways. Load factors exceeded 90% in July 2026, though a single month does not establish a long-term trend.
Industry impact & what to watch
Asia connections from the US East Coast have historically run through Japanese and South Korean hubs such as Tokyo Narita and Incheon, served by carriers including All Nippon Airways, Japan Airlines, Korean Air and Asiana Airlines. A non-stop Taipei service gives Washington-area travelers a different gateway, and passengers can connect through Taipei to destinations across Asia-Pacific. The route gives Taipei a larger role on the East Coast.
Flights of this length on a 787-9 depend on strong premium demand and consistent loads to hold their economics, which is why the increase from three to four weekly frequencies and the July load factor above 90% matter as early signals. One strong month is not a trend, so the more meaningful test is whether loads hold through the off-peak months.
The $61 million economic impact estimate is a joint projection by the airline and the airports authority rather than a measured result, so any later published figure from the Metropolitan Washington Airports Authority would be the first real check on it.
