A:AnswerDepends on who you are. If you're not the registered owner then there is a mechanism where it'll ring / ping iPhones that it is near to say that this AirTag has been following you. If you're the registered owner, it won't show the level of granularity to pinpoint where exactly in a vehicle it is without possibly ringing the tag.
A:AnswerI don't believe so but could be wrong. Only the device owner has access to the tag's location, as far as I know. I would like to share the info myself but don't think it's possible - unless you can log in to the owners Apple acct. They run on Apple's Find My app.
A:AnswerI just used it flying domestically and didn’t have any problems. I don’t think it has a lithium battery. I’m using it on British Airways next week.
