1. We recommend Google Flights to find these trips because it has an easy-to-use calendar tool to browse dates and fares. See an example itinerary by pressing the blue button below.

Select one of the date boxes to expand the calendar view and see fares for each departure date. The fares shown will update if you pick a longer or shorter trip - trying different lengths can reveal more options.

Once you find dates at the cheapest price, select the outbound and return flights to see booking options. You can book with an Online Travel Agent for the lowest price, or go directly with the airline.

Note: you may find some scattered Air France routes from Heathrow in the £150s too.
