Hi, I am in the same situation from connecting through Helsinki back to Irekand from Lapland on the 19th. The baggage tracing is useless and emails are ignored. The website is pointless because it needs Finnair to actually trace the bags for it to be of any use!
With baggage labels it must be possible to enter the barcode number and see where it was olast scanned but I cant even see this information.
I found Finnair excellent to fly but have changed my mind and will not be using them again.
