There is a thread in a.net stating that AY and CZ would start codeshare flights from CAN to Chinese destinations and to Australia and New Zealand and from HEL to European destinations. Probably also btw HEL and CAN route flown by both companies. I find it strange that AY has not made a press release even though the sign up should have been Done on the 19th of December. I wonder if there is any truth in the news or if they are waiting for governement approval. The poster in a.net had found this piece of information from Weibu. The post quoted up to 15-16 routes from each hub.
