I'd really need an educated advice about where we should check our bags to on multiple leg flights. I did various things in the past and things always went well but with all these horror stories of lost luggage, maybe I was just plain lucky.
The last long haul I did was BEG-MUC-GRU-GIG on LH/JJ. Bearing in mind that when traveling to USA luggage should be picked up at the first point of entry and re-check for any following internal flights, I had a hunch that it would be okay to check my luggage to GRU only, to pick it up, clear the customs and border control and re-check it for GRU-GIG leg I was flying on JJ. I did the same on my way back. There were no problems whatsoever. I asked LH staff at BEG what would be the wisest options. The lady politely and in cold manner responded that she will do whatever I decide. I asked three times but she remained stubborn in "no advice" policy... so no tips there. It was possible to check it through all the way to GIG so the choice was all mine.
I was wondering, what would happen if my luggage was late in arrival to GRU and I had to continue my journey in either way and my luggage was tagged to GRU only. Would it remain there?
What are the options here? Should luggage be always tagged all the way to the final destination or there are exceptions? Should we tag it to the first point of entry only? Any piece of advice will be greatly appreciated.
