Lounge options at LED?
 

My wife and I (both AA Gold) and my son (aged 10) are flying this summer to multiple destinations on a OW Business Class award. Due to limited availability, on some of the segments we had to take a voluntary downgrade to Economy. We fly LED-HEL on AY in X and then LED-MAN also on AY but in U. Can anyone tell me our lounge options at LED? Will AY allow us to use their lounge? My understanding from reading other posts that there are no other OW lounges in LED.

I flew BA back to London from St Petersburg in Economy in early March and the lounge was a 3rd party lounge (the Pulkovo Room or something like that) that we got invitations for at check-in. I don't recall seeing signs for any OW-operated lounges.

If you're flying Economy from LED-HEL, then I don't think they'll issue you an invitation at check-in and unfortunately, I don't think your AA Gold status will help at all. If you're flying on to MAN from HEL in business though, then of course you'll be able to access the dedicated AY lounges in HEL airport.
