COK will also have DF on arrival near the baggage claim before customs.
OP is fortunate enough to get this information here on the forum. AI staff in Toronto will not give this information to passengers
resulting in many COK passengers exiting immigration at Delhi to wait for their luggage which will never arrive :-( Usually
there is AI staff yelling about this information in Delhi but it is very easy to miss this in a jetlagged state of mind.
Easy way to fix this is to make first arrival airport in India as your immigration/custom processing port. Easy to
remember ! My $.02.
