United Airlines will launch a short-lived nonstop between Tokyo Narita and Las Vegas in January 2027, timed around the Consumer Electronics Show (CES), which runs January 6 to 9. Just three flights in each direction: Narita to Las Vegas on January 3, 4 and 5, and the return runs on January 9, 10 and 11. Las Vegas isn't a United hub, so this is a pop-up service aimed squarely at CES demand from Asia.

The odd part is the equipment. Flights heading to Las Vegas use a 276-seat Boeing 777-200ER with 50 Polaris business seats, borrowed from a San Francisco rotation. The returns to Tokyo use United's new "Elevated" 787-9 — its freshest widebody interior, debuted in 2026 — with just 222 seats, of which a huge 64 are Polaris suites and 35 are Premium Plus. That's 54 fewer total seats than the outbound jet, but considerably more premium capacity.

Why the mismatch? It mostly comes down to aircraft availability and opportunity cost. United didn't want to ferry the 787 to Las Vegas empty, so it pulled it off the Houston–Narita route for three days — a route that can absorb the cancellation in the quiet mid-January period. Meanwhile a spare 777 had enough slack in the schedule to work a San Francisco–Narita–Las Vegas loop. The logic is fleet juggling, not a statement about either aircraft.

Still, sending the flagship jet makes commercial sense. CES traffic skews heavily business and premium, so a plane with more than 40% of its seats up front should sell well at high fares. The Elevated 787 also doubles as a marketing exercise: show well-heeled Asian travellers United's best product — reverse-herringbone Polaris suites with sliding doors, larger screens, and centre pairs that convert into a double bed — and they may come back. The flights also plug a gap: until now, Star Alliance customers, including those loyal to joint-venture partner All Nippon Airways, had no nonstop option for CES.

United isn't alone here. American has run January-only transpacific flights from Las Vegas for years and will fly Narita and Seoul Incheon nonstop in 2027, while Delta is scaling up aggressively with CES routes to Seoul, Hong Kong, Shanghai, Taipei, plus London, Paris and Amsterdam. It's a tiny annual window, but a lucrative one — and United is the newcomer testing the waters.

If you're heading to CES from Asia, there's finally a nonstop option worth booking early. The Elevated 787 is arguably the best business-class product United flies, so returning travellers get the nicer jet.
