What actually happened on the TLL/AMS leg was that first there was no seat selection on the airBaltic check-in, I had already chosen seats for the AMS/EDI leg.
I did get into the lounge, the boarding card had "sold as KL2846" on it along with my FB status.
Boarding in Group 5.

The airBaltic printed boarding card for AMS/EDI had no status or group information on it, but KLM wrote group 2 on it for me.
TLL plane was on a stand so no bus.
