Well...
10 September 2014 is the move date in case anyone wasnt aware.
Google search gets this info:
Lufthansa will open its own lounge at London Heathrow's new Terminal 2 next October.
As previously reported, both United and Air Canada will have their own lounges at T2 (see news, November 6).
There will be no separate Star Alliance lounge such as that existing at T1 presently.
So it would seem likely that SAS will continue to have their own lounge once migrated over to T2.
