I have what seems like a pretty vanilla situation coming up next month but after perusing the thread and wiki it is not clear to me what I should expect.

Traveling KTM-DEL-WAW on Vistara and Lot, one PNR, J. 6PM-8AM layover in DEL. I will have bags.

Should I expect my onward BP to be issued in KTM and bags checked through so that I can walk through the I-I route in the wiki and go hide in a lounge (and if so, where should I aim to park myself? Also have Amex plat)? Or will this be more complicated?

Thanks
