As someone who has been one bagging for four months now I can’t recommend having an air tag enough.

I have an air tag that stays locked in the same part of the bag that keeps my passport, alternative bank cards, laptop & kindle.

Definitely helps lower anxiety as I stay in hostels, hotels or travel in busses etc. Havent ever had to use it but have used it to see if the bag is still in the bus and moving with me or in the hostels locker while I’m having lunch.
