Always a good idea. I always have a screenshot and a pdf on my phone.
BUT, in India, you can't get into the terminal without one of these.

And they will sometimes give you a hard time if you go to the airport too early.

And they have redundant (but not really useful) checks

And the list goes on for India.
A fun experience to transit or flying in and out of India.
