Bags are tagged for a tight connection. Your bag might be off loaded before the door is opened. The distance bags travel on the tarmac is shorter then the distance pax have to travel. Bags can be loaded after the door closes.Depends on if you are checking luggage. I don't know those airports so I don't know if 45 min. would be enough, we fly out of Atlanta and in some cases that would be fine, in others not. I wouldn't do a layover if I were checking luggage, just too much opportunity for it to get lost. If you are doing carry on only, even if it gets gate checked you know it's going on the same plane you are on so it wouldn't be that much of an issue.
Bags missing the connection but the pax making the connection is uncommon.
Twice I had missing bags. Once they were never loaded on the plane. The other time they weren't unloaded; they stayed on the plane
