Found this great advice for travellers from British airways airline.
1. Do not write your address on luggage tag. Drug paddlers and other criminal may secretly stash their goods and loot in your luggage. If you clear immigration, they will go to your address to get from you. If you fall immigration check, say good bye to freedom as you sit behind bars. So just indicate contact number and email. If luggage goes missing, airline would call/email you when found.
2. Do not leave boarding pass as rubbish in the passenger seat pockets. Criminals can scan the QR code to get your full name and other details. And can even steal your mileage points etc.
