First time on Finnair and I'm trying to deduce which fare class a Coach class award booking from LHR-HEL-SIN on Finnair booked via Alaska Mileage Plan falls into.

As far as I can see there is no checked bag included due to the first leg being shorthaul, and so a checked bag needs to be purchased. But I'd like to know the fare class of the booking to confirm this. Quite surprised if this is this case as I've always had a checked baggage allowance due to the longer sector on every other award program I've ever used.

Alternatively if anyone has any direct experience of flying Europe shorthaul into HEL and longhaul onwards from there using Alaska and is willing to share their experience around checked baggage being included or not, that would be great too.

Thank you.

Edit: I've found that it's fare class X. Does anyone have the checked baggage entitlements of that fare please?
