Cheap flights from Belfast to Reykjavik

Iceland's weather swings hard between seasons, and daylight does too — Reykjavik gets long bright days in summer and short dark ones in winter, which is exactly when fares move. April is the cheapest month on this route, and the calendar here covers October through May plus the July and August peak. School holidays and the Christmas period push prices up, so shifting a trip by a week or a weekday can change what you pay.

The mix is broad: Easyjet works as the low-cost option, while British Airways, BA CityFlyer, Aer Lingus and KLM Royal Dutch Airlines sit on the full-service side. Every flight on this route connects, so the stop — often via one of these carriers' own hubs — matters as much as the fare. Low-cost tickets typically cover little beyond the seat, with bags and seat choice as extras, while full-service fares usually include checked baggage and on-board service. Check what your fare includes before comparing on price alone.

Keflavik International is a compact airport, so arrivals walk out quickly and transfers into town start within minutes. It sits some distance from central Reykjavik, and the usual ways in are scheduled shuttle buses and pre-booked transfers, with car hire also available at the terminal. Watch the ground-transport hours against your landing time, since late connections into the city can thin out.
