For December travel from Denver International Airport (DEN) to Edinburgh Airport (EDI), the sweet spot is early-to-mid December (excluding the last two weeks around Christmas and New Year) to combine lower fares with milder airport crowding. Book flights 8–12 weeks in advance for general December travel; for Christmas and Hogmanay dates, secure tickets 4–6 months ahead. Flying mid-week and selecting early-morning DEN departures reduces the risk of cascading weather delays; for returns, avoid late-night connections on New Year’s Day when services may be limited.
