I am not denying your opinion
@SithLord but as far as I have experienced if you have separate tickets you need to exit the airport and check in again does not matter even if its under same alliance. Airlines or air port authorities may be lenient during Covid times (as I have read 1 person doing it via London) but its better not to take risk unless we are sure.
This is what my friend told me that he hates about India: the sheer clusterduck of contrasting information. Nobody is on the same page about the travel updates. Everybody follows different orders, kowtows to different authorities. It's no longer paranoia-- you would be wise to take print outs of emails, official communiques, government dossiers, Scam India's rules and regulations PDF, Twitter screenshots etc., so that you can prove to the airport entrance chap that you are allowed to enter the premises to fly out, then to the baggage
wala guy to check your baggage all the way to final Canadian destination, then the boarding area fellow that you are legally allowed to fly.
I would rather my COPR expire In September, and wait for normal flights to resume in their weakened capacity than attempt all this juggernaut business of multiple flights, transits etc. Bhai, so many places to go wrong. Then if we are stuck in some place In Europe, nobody can help us. Meanwhile our baggage will be blown up by airport security in Vancouver as a security measure because it's been spinning around on the conveyor for a whole day and nobody has claimed it.
