This has been a popular offering over the past few years for FTers, and more Canadians have asked about it. So here's the registration link for this year's offering which starts next Wednesday:

Each day you'll receive an email offering a different "mystery" European destination SK flies to. You can book the special fare for the next 24-hours, for travel dates between mid-January and sometime in late March [dates have not been confirmed for this year yet].

Unfortunately, flights are only from US gateways [SEA, ORD, EWR and IAD] and prices last year were $299 plus taxes/fees from SEA and ORD, $259 from EWR and IAD. This means you must factor the cost of getting to these gateways, possible hotel night(s) and mid-winter weather delays. However, given the improved exchange rate on the US$ these days, if the fares remain at this level for this year's promotion, you'll be a C$100 ahead on what we were paying over the past couple of years on these flights.

However, these can be great mid-winter breaks for a couple of days in the European cities on offer, as there is no minumum stay [other than Saturday overnight] which would apply on most discounted AC fares, save for LHR.
