Lufthansa has put out a new set of electronic discount vouchers.
Go to this website, select your country, and Lufthansa will email you a discount code off your next flight. The UK voucher is worth £17.
Now, here is the interesting bit.
Usually Lufthansa only releases these vouchers for one country at a time. This time, they are available from pretty much everywhere.
So … if you are booking a European route where Lufthansa sells one-way seats, you can use two vouchers. If you want a weekend in Berlin, get a £17 voucher to use against a UK-Berlin one-way, and a €20 voucher to use against a Berlin-UK return leg. You may need to clear cookies or use a different browser to get a second voucher in a different currency.
Flights must be booked by 10th March, for travel by 10th June.
