Airlines is the preferred carrier for domestic flights.
Always check with NU Travel before purchasing airline tickets elsewhere in order to compare prices. You are also encouraged to plan travel in advance in order to take advantage of discounted tickets. For reimbursed professional travel, the department can pay NU Travel directly for tickets so that travelers will not need to pay out of pocket. However, if they choose to purchase airline tickets elsewhere, they will not be reimbursed until after the travel has occurred. 2.Have travelers use a Travel and Expense Report Form to record all expenses.
