Apologies if this has been asked before, searching for "interline" or "interlining" doesn't come up with useful results..

About to make a trip to Europe via Canada (from US). First leg is on Delta (F), then KLM (WBC) via AMS to our final destination.

Delta and KLM flights are on separate PNRs.

How likely is it that Delta will interline our bags to our final destination so we can avoid collecting our bags and re-checking with KLM ?
