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

Don't forget to change the fare class to either 'Economy' or 'Premium economy', depending on which fares you're looking for. 

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. Some of these fares might show up in £450s+, but will drop once you click through to the last page of Google Flights.

You can find the cheapest fares with an Online Travel Agent via Skyscanner in step two, or book with the airline or Google Flights' OTA once you select both flights.

Note: If you're flying economy and plan to add checked luggage with Lufthansa, it's cheaper to select the fare class that includes it, rather than add it as an extra. Google Flights takes you to a page on their website with the fare class already selected. To change it, click the back button in the bottom left and choose your flights again.

To get the lowest fares (listed above), book with an Online Travel Agent (OTA). Skyscanner lists OTAs that are the cheapest for this deal - see an example through the blue button below.

On Skyscanner, enter the itinerary you found in step one and wait for the search to finish loading - it can take 20-30 seconds. Book with the cheapest OTA or the one you like the most.

Top tip: Quickly convert your Google Flights finds to searches on Skyscanner with our Fare Compare browser extension. One click and you're done :-)
