Looks like they have difficulties in attracting passengers to CKG. Not a week goes by without an offer to CKG.
The Crazy Days campaign offer of 419 € HEL-CKG (actually the ticket cost me only 416 €, perhaps due to currency fluctuations) was IMO better than this. Earns full AA mileage and is upgradeable.
Soon they will pay people to fly to CKG, at least in Y.
I wonder if the J sales are better.
