text:  uh american and delta they have baggage tracking services too built right into the app so once you check in your bag the air use the airlines official app to follow your bag on its entire journey from check-in to the final destination so you're going to get notifications along the way like for example when the luggage is on the plane when it arrives at the destination when it's at the baggage carousel and then there's a map that shows you exactly where the luggage is at any given time but there is a time when it doesn't report back
