I am not sure if Aegean/*A follows this rule, but in QR if a flight is available for an award, it is also available for an upgrade.
This way, you get some extra miles/tier points and also avoid the surcharges.

As Fransknorge wrote, upgrades on Turkish are only available in classes Y and B. A quick search for random dates in February shows CDG-SGN-CDG available in B at EUR 2,840. The upgrade itself would cost 100,000 miles, and you would earn around 13,000 miles for the ticket. In addition, an upgrade would also trigger a recalculation of taxes and surcharges. Itamatrix indicates an increase of 334 in taxes, thus putting the total cost at 3,174 euros plus 87,000 miles.
