Under tier benefits on AY webpages, it now reads:
"When travelling on Finnair flights (AY code on the ticket), you have access to the Finnair Lounge services. This benefit applies to you and one guest travelling on the same flight. At other airports, the lounge benefit applies only to the lounge printed in your boarding pass and only when travelling on Finnair flights."
(The same for Platinum and Lumo (one -> four guests for Lumo).)

But: same flight, only Finnair flights, only lounge printed on boarding pass??
Has the text always been like this? Or has something changed, are these rules really enforced now?
(Could they even enforce these, would be different from OW tier benefits?)

This of course differs from what I was expecting, which is still written at
...smooth-travelling-at-helsinki-airport/finnair-lounges-at-helsinki-airport (Sorry I cannot post URLs yet, apparently)

"As a Finnair Plus Platinum Lumo member, you can bring four guests. If you hold a Finnair Plus Platinum or Gold card, you can bring one guest. As a Finnair Plus Platinum Lumo, Platinum or Gold member, you can bring your children under the age of 18 with you. Guests need to travel on a flight that is operated and marketed by a oneworld airline."
