Will someone else be able to make my travel arrangements for me?

Yes. You can assign, in your profile, as many travel arrangers as needed. The implementation of Concur Travel and Expense should have no effect on who makes your travel arrangements. Go to your Profile and either scroll to the page to the “Assistants and Travel Arrangers” box, or click “Assistants/Arrangers” from the My Profile menu on the left side of the page. Click Add an Assistant to add the person who you would like to authorize to book your travel. This person can update your profile and make any travel arrangements for you. Arrangers or assistants must have their own login.
