I'm going to follow paultheparaglider and go for a slight diversion.
In 1978 I flew London/Frankfurt/Delhi (on Lufthansa) connecting to Royal Nepal Airlines (as it then was) to Kathmandu. Eveything went swimmingly at Heathrow, I got my bags checked to KTM and got boarding passes to DEL.
On arrival at Delhi I had to enter India (took a while but I had about 3 hours). I wandered round to the RNAC desk and the man asked if I had baggage. I proudly showed him my bag tag. He said "follow me"; took me through passport control into the departures lounge and asked if I could see my bag and, there it was upside down parked against a pillar. I picked it up, followed him back to check in got a new tag and a boarding pass and boarded the ropiest 727-100 I think I ever flew on.
I hope things have got better!
