Finnair reward flights

[hatched]

Hi All.
Does anyone know if you can cancel a Finnair reward flight booked through the BA website (cancel in the same way a BA reward flight can be cancelled for for a fee and refund of avios). Haven’t booked yet but not sure of dates while we check accommodation so they may change and don’t want to miss out on flights.
Thanks

If you book via BA then BA T&Cs apply

If you book via any other then it’s theirs.
