To snag cheap flights from Boston Logan International Airport (BOS) to Copenhagen Airport (CPH) in December, start by searching flexible dates and scanning the full month to identify low-fare midweek departures. Be open to one-stop routings via Reykjavik, London, Amsterdam, or Frankfurt which often reduce fares compared to limited nonstop options. Use fare aggregators (Google Flights, Skyscanner, Kayak), set price alerts, and check airline promotions directly on SAS, Icelandair, Delta, KLM and Lufthansa. Consider flying early December rather than peak holiday dates, choose red-eye or late-night options to save money, and factor baggage fees into the total trip cost.
Tips
- Book 2–8 weeks in advance for December but earlier for holiday peak dates.
- Search flexible dates and +/- 3 day calendars to find midweek deals.
- Compare one-stop itineraries via KEF, LHR, AMS to reduce cost.
- Use fare alerts and check both roundtrip and two one-way options.
- Factor in baggage and seat selection fees when comparing carriers.
