Yes I know that I have already posted this in the Mileage Run but since not everyone is reading that forum I will put it here as well.

Lavish your loved one this year with a romantic trip to Geneva, Milan or Brussels.
It's easy, it's cheap and it's only available here on February 14. Travel to Europe and discover romance all over again. SAS will give you about a month to do so. After that, you're on your own.

Prices are per person based on round-trip ticket purchase and do not include taxes and airport fees.

and remember you can only book this prices online on the 14th of Feb.
