I don't know why I didn't notice the flight times mentioned in your first post.

Assuming you are talking about your Vistara+AI plan, those connection times look comfortable, even with checked baggage as long as no terminal change is involved. Just be a little "aggressive" with immigration process: have the forms filled out in the plane, visit the rest room the plane so you won't have to stop after arrival and can walk fast to the front of immigration lines.

Being able to travel handluggage-only, though not necessary, is of course always an extra pleasure, whenever possible. Good luck.
