Cheap flights from Belfast to Tokyo

May stands out as the cheapest month on this route, so if you can adjust your dates, aim there. Outside that window, October through June all carry prices that fluctuate with demand rather than seasonality alone. Weekday departures generally cost less than Friday or Sunday flights, and avoiding school holidays in both Britain and Japan helps keep fares down. Book well ahead for May travel since the best deals disappear quickly once summer approaches.

The full-service carriers on this route include British Airways with its BA CityFlyer subsidiary and KLM Royal Dutch Airlines, each offering different connection points depending on your preferred hub. Aer Lingus also operates connections through Dublin rather than London. Easyjet tends to cover only the European legs of such journeys, meaning you would combine it with another ticket for the long-haul section. What varies between these airlines is baggage allowance, seat selection fees and whether meals are included in the base fare.

Tokyo offers two main airports — Haneda sits closer to the city centre while Narita lies farther out, each shaping how you reach your final destination. Haneda handles more domestic and regional traffic alongside international arrivals, which means shorter transfer times but potentially crowded terminals during peak periods. Narita attracts longer-haul carriers from outside Asia and Europe, so expect larger aircraft and sometimes longer waits at immigration. Trains run regularly from both airports into central Tokyo with transfers available depending on which terminal you land in.
