Reykjavik–Keflavik (KEF) is one of the most accessible European gateways from the US, thanks to its role as a popular stopover hub. Icelandair and PLAY both fly nonstop from a long list of East Coast and Midwest cities, including BOS, JFK, EWR, IAD, BWI, ORD, MSP, and SEA, with flight times of roughly 5 to 6 hours — noticeably shorter than most transatlantic routes.
Winter (November–March) is Iceland's cheapest season and also aurora season, drawing travelers chasing the northern lights despite the cold and short daylight hours. Summer (June–August) is peak season, with nearly round-the-clock daylight, the highest fares, and the biggest crowds at sites like the Blue Lagoon and Golden Circle. Shoulder season (April–May and September–October) offers a solid mix of lower fares and reasonable weather.
PLAY, Iceland's dedicated low-cost carrier, undercuts on headline price but sells its cheapest fares first and charges extra for bags and seat selection. Icelandair, the full-service flag carrier, tends to hold better fares — including more generous baggage allowances — for travelers who book in the middle of the window rather than at the last minute.
4–6 weeks out on Icelandair, or 3–5 weeks out on PLAY's budget fares. Reykjavik's popularity as a stopover hub means flexible dates often unlock the best deals.
November–March is cheapest and doubles as aurora season. Summer (June–August) is peak price and nearly 24-hour daylight; shoulder season balances the two.
PLAY often has the lowest headline fare but adds fees and sells out fast. Icelandair usually offers better value with more flexibility if you book in the middle of your window.
