It worked for me. I registered and sent in a status match request (with an screen grab of my Finnair Gold card) last weekend and got confirmation today that the status match was granted.

I am yet to try it, but Asante Gold seems to give benefits on par with or above Finnair Gold. I am not going to fly a lot on Kenya Airways but the card's SkyTeam Elite Plus travel benefits (two-pax lounge access, priority check-in, security, and boarding, free seat selection, extra piece of luggage) should carry over to flights on other SkyTeam members. With, e.g., Delta, KLM, Air France, Korean Air, China Eastern, and Virgin Atlantic, SkyTeam is actually an interesting alternative to OW or *A.

It remains to be seen how well everything works in practise.

Cheers,
