I'm curious.
Under which circumstances have people had luggage issues (perhaps all, but if only certain types of circumstances, then perhaps we can minimize potential for problems by avoiding those cases, if possible).
1) Had luggage issues even though my flight was a point-to-point flight, eg. Flew from Chicago to London and then picked up my luggage (or tried to) for a tour starting in London
2) Had issues with my luggage when my flight connected in a domestic or foreign city to another flight but all within the same airline (not counting partner airlines as the same airline)
3) Had issues with my luggage when my flight connected in a domestic or foreign city to another flight but they connected to a partner airline
Just curious if there is any difference (probability in having luggage issues) in the three cases described
