> About reservations, I don't see why would you want to move your data. Reservations are tied to companies in a way no standard can solve. And by design. Maybe company A has a history of all your travel reservations with them, and company B has a history of all your travel reservations with them. Then company C offers a service where they collect travel reservations from various services to create an business expense report. You, the supposed owner of the data would like to authorized C to import your data from A and B.
