Route Briefing: Denver to Beijing
Denver sits at the crossroads of the American West, but from its international terminal you can reach one of the world's great imperial capitals in a single journey — and when fares dip below $700 roundtrip, this route becomes one of the most compelling long-haul deals available from the Rockies. The flight runs around 13 hours and 30 minutes with one stop, typically routing through Seoul or Tokyo, and that layover is actually a feature rather than a bug. Korean Air connections through Incheon and Air China routings through Asian hubs frequently undercut more direct options, so a few hours in a world-class transit airport can translate into real savings. United Airlines also serves this corridor if you prefer accumulating miles within a familiar program.
Beijing rewards the effort immediately. This is a city where you can stand inside the Forbidden City — the largest surviving palace complex on earth — and feel the full weight of dynastic China pressing down on you. The Great Wall snakes across the mountains north of the city, and no photograph fully prepares you for the scale of it. Beyond the headline monuments, Beijing's hutong neighborhoods offer a quieter, more intimate version of the city: narrow alleyways, courtyard homes, and the kind of street food culture that has been refined over centuries. Peking duck here is not a restaurant dish, it's practically a civic institution.
Timing matters considerably on this route. June through August brings warm weather but also peak crowds and prices, while Chinese New Year — falling in January or February — creates a spectacular but logistically complicated travel window as hundreds of millions of Chinese travelers move simultaneously. For the sweet spot of manageable crowds, pleasant temperatures, and better fares, aim for late September through early November when autumn light settles over the city's ancient rooftops beautifully.
Getting from Beijing Capital International Airport into the city is straightforward. The Airport Express train connects directly to central Beijing stations and is fast, affordable, and far preferable to sitting in taxi traffic during peak hours.
The single most useful tip for this route: book three to six months ahead and set fare alerts specifically for stopover routings through Seoul. That combination consistently surfaces the best prices from Denver, and locking in under $700 roundtrip for a journey this historically and culturally rich is genuinely exceptional value.
