From 1st December bookings for live animal shipments must be made through a forwarding company
From 1st December bookings for all live animal shipments, like pets, must be made through a forwarding company.
This means that the forwarding company will help with all the pre-arrangements and ensure all documents are in order and they will bring the animal to the terminal.
You can find a list of forwarders on the website of the Finnish freight forwarding and logistics association: http://www.huolintaliitto.fi/en/membership/member-companies.html
ATC Global Solutions is one forwarder based near Helsinki Vantaa airport which regularly handles live animals: https://www.travelcargo.fi/en/
