Your report is a good read so far!

To answer you on KIV, there is a lounge which is open to Priority Pass. Their directions are:

"Airside - after Passport Control and Duty Free, turn left. Take the escalator or stairs to the 2nd Floor and turn left. Pass the 'Golden Jet Restaurant' and then turn right to where the lounge is located."

Apparently LOT don't pay for KIV lounge either, but the *A finder shows OS and LH does.

You're right that there is also a dictator terminal. Looks very nice and you can even pay for a pretty Moldavian girl in national costume to give you the bread & salt service.

Sounds lovely!
