The bigger lounge has opened on the 20th of December. I have not yet visited the lounge. I have only a link to commercial source Finavia newsroom. BA Silvers are entitled to use this lounge even though the assigne BA lounge is almost@home.

P.S. After posting I found this thread New Finnair HEL biz lounge. JP = Joseph Perrier Champagne was also mentioned to be offered at the manned Bar open during the rush hours.
