Expected response from DL below. Anyone knows contact information for SkyTeam?

Claims Manager
Central Baggage Service

Your e-mail has been forwarded to me for response to the mishandling of
your luggage. I am sorry to learn about the circumstances you describe.

The airlines have an agreement whereby the passenger's final carrier
investigates irregularities related to loss, damage or delay of luggage
on behalf of everyone involved. They normally have immediate access to
baggage claim checks, ticket receipts and other essential information.
In general, this system benefits both the customer and the airlines by
eliminating duplication of efforts.

Since Aeroflat was your terminating carrier in Moscow, you must contact
them regarding your claim.
