Estonia Air, ? Code share with KLM
 

Where can I check if Estonia Air is code shared with KLM? I'm looking at a trip Toronto to Tallinn via Amsterdam offered by FareDepot. The Toronto - Amsterdam portion is with KLM and the AMS - Tallin leg is with Estonia Air. With a tight connection time, I don't want to be stuck buying another ticket if I miss the connection @ Amsterdam.

It's irrelevant whether the second flight is code-shared by KLM. Only thing that matters is whether the two legs are booked on the same ticket.

The standard advice is to book with the airline - KLM - rather than a third party.

The KLM website for Canada shows several combinations to get you from Toronto to Estonia and return. KLM will sell you tickets that may involve Air Baltic or Estonia Air. The trans-Atlantic flight might even be on Air France through Paris. The website will tell you who operates the plane. The itinerary still remains KLM's, as does the responsibility for getting you there and back. I checked flights in October and they looked even cheaper bought direct from KLM than the agency site you named. For a trans-Atlantic itinerary, it's really really cheap.

Thanks everyone, it makes more sense now.
