✈️ Flight Guide: Chicago (Any) → Copenhagen (CPH)

March events in Copenhagen can include Fastelavn (the Danish carnival-style celebration) which sometimes occurs late February or early March depending on Easter, and small cultural exhibitions, museum openings, and culinary pop-ups as the city prepares for spring. Easter-related markets and services can occur in March if the holiday falls in that month—expect busier weekends and higher accommodation rates. Nearby Malmö often runs spring markets and design exhibitions, while Aarhus and southern Sweden may host local festivals and seasonal concerts. For March travelers, book popular museum or concert tickets ahead and verify opening hours around public holidays. CTA: Check local event calendars before booking your March trip and reserve event tickets early.

March is a good balance between lower shoulder-season fares and improving spring weather in Copenhagen. Early March generally yields better deals than late March if Easter arrives that month; flying midweek often reduces costs. For milder weather and festival planning, consider late March to early April for longer daylight and the start of spring events but expect a modest fare increase. CTA: Compare flexible March date ranges now to find the ideal balance of price and weather.

Direct flights minimize total travel time and simplify baggage checks—ideal if you prioritize speed and comfort—but tend to be pricier and may be seasonal from O'Hare (ORD). Connecting flights through hubs such as Amsterdam (AMS), Frankfurt (FRA), London (LHR), or Reykjavik (KEF) offer more schedule options and often lower fares in March, but increase complexity and risk of delayed connections. If you want to explore a stopover city, a connecting route can double as a mini European visit; otherwise choose a nonstop when available for a faster CHIA to CPH transfer. CTA: Search both nonstop and one-stop options to compare total travel time and price.

Key airlines for CHIA to CPH March travel include SAS (Scandinavian Airlines) often via direct or codeshare routes, KLM via Amsterdam (AMS), Lufthansa via Frankfurt (FRA), and carriers like Delta or United offering transatlantic connections via their partner networks. SAS tends to provide the most seamless Scandinavian connections and Scandinavian-focused service; KLM and Lufthansa offer robust hub frequency which can mean shorter layovers; low-cost transatlantic options may appear via Reykjavik (Icelandair or play) or with discounted fares on legacy carriers during sale periods. Compare total trip time, fees for checked baggage, seat selection costs, and alliance benefits (e.g., Star Alliance vs. SkyTeam) when choosing an airline for March travel. CTA: Compare airlines and book the best balance of price and convenience for your March itinerary.

Pack layers, a warm waterproof coat, and comfortable footwear for March travel between Chicago (All Airports) (CHIA) and Copenhagen Airport (CPH); temperatures can range from near-freezing mornings to cool afternoons.

Allow extra transfer time at Chicago airports for possible winter weather and plan train or bus connections at Copenhagen Airport in advance. CTA: Prepare a March-specific packing checklist and confirm weather before departure to ensure a smooth trip.

Typical one-stop flight times from Chicago (All Airports) (CHIA) to Copenhagen Airport (CPH) in March range from 10 to 14 hours total, including layovers; nonstop flights (when operated) are about 8.5–9.5 hours.
