How likely is it to have access to the SK lounge with a TP Y ticket operated by AY being *A Gold? Or to the C/CL check-in counters in HEL?
Many thanks in advance.

I first now saw the "operated by AY" part, which probably makes my reply below wrong.

If the SK lounge displays the Star Alliance sign (which I believe it does) TP Y with Gold card should grant access.
With a *G card in the FF-field, your boarding card should read "FAST/LOUNGE".
