United Airlines began daily nonstop flights between Newark Liberty International Airport and Seoul’s Incheon International Airport on 4 September 2026, becoming the first US carrier to fly the route direct. The service uses a Boeing 787-9 Dreamliner configured with 48 Polaris business-class lie-flat seats, 21 Premium Plus seats and 188 seats split between Economy Plus and standard economy.
The westbound flight leaves Newark at 10:35am and lands in Incheon at 3:20pm the following day, a scheduled block time of just under 16 hours. The return flight departs Seoul in the late afternoon and reaches Newark the same evening, taking around 13 hours 45 minutes with the help of Pacific tailwinds.
Filling a gap in a growing market
Seoul has quietly become Newark’s largest market in East Asia, with roughly 179,000 round-trip passengers travelling between the two cities in the year to mid-2026, ahead of Tokyo. Until now, travellers from the New York area flying nonstop to Seoul had only one option: Air Premia, a South Korean low-cost carrier that has flown Newark to Incheon daily since 2023. Korean Air and Asiana Airlines also serve Seoul from the New York area, but from John F. Kennedy International Airport rather than Newark.
Part of a wider transpacific push
The Seoul route is one of 14 new nonstop routes United has launched from Newark this year as it works to strengthen the hub’s long-haul network. For United’s Polaris and Premium Plus customers, the flight adds a lie-flat option on a corridor previously dominated by a single low-cost competitor and two carriers based across town at JFK.
Why it matters
The new route reflects how much transpacific demand has shifted since the pandemic, with East Asian business and diaspora travel now dense enough to support competing nonstop options from more than one New York airport. For Newark, landing a premium long-haul route to one of Asia’s key business and tourism hubs adds weight to the airport’s case as United’s preferred East Coast gateway to Asia.
