Denver (DEN) → Copenhagen (CPH): cheap fares overview
Denver to Copenhagen isn't the most straightforward routing in the world — there's no nonstop, so you're always connecting somewhere, usually a major European hub like Amsterdam, London, or Reykjavik. That layover adds a variable to the price equation that most routes don't have. Fares tend to be lowest in late winter and early spring, when Scandinavian tourism is quiet and transatlantic demand drops off after the holiday rush. Summer is when prices climb hard — Danes come home, Americans chase the long daylight hours, and airlines know it. School calendars on both sides of the Atlantic matter more than people realize.
Why travel from Denver to Copenhagen?
Copenhagen punches above its weight for a city its size. Americans go for a lot of different reasons — some are chasing the food scene, which has quietly become one of the most influential in the world over the last decade. Some have Danish ancestry and are doing the family roots thing, which is more common than you'd expect in the Mountain West. Others are there for design and architecture, or using CPH as a base to hop into Sweden or Norway, since Copenhagen's 200 nonstop destinations make it one of the better-connected hubs in northern Europe. Business travel between Colorado's tech sector and Danish companies in pharma and clean energy is a real segment too. And honestly, some people just want to ride a bike along a canal and eat a smørrebrød without overthinking it. That's a valid reason.
How to find a cheap fare on this route
If you're flexible, February and March are your friends on this route — demand is low and you'll find the most room to negotiate with your dates. Booking eight to twelve weeks out tends to hit a sweet spot before prices firm up. On the Denver end, DEN's 235 nonstop destinations give you solid options for positioning flights if a connecting itinerary through a different US hub saves money. On the European side, consider whether routing into Malmö or Stockholm and taking a short train into Copenhagen makes sense — sometimes the math works out. Icelandair runs a well-known stopover program through Reykjavik that occasionally produces cheaper fares than more direct routings, and a free layover in Iceland isn't exactly a punishment.
