TRAC can be a pain, especially for those of us who do not use it often.  The traveler needs to submit a request that needs to be approved by his or her supervisor, for schools, it is usually the principal.  To do so, the traveler needs to complete a TRAC, which requires a lot of information, such as air travel price, hotel price, hotel tax, cost to seminar or registration fees, estimated cost of food, ground travel expenses, incendiary expenses that needs to be refunded.  Unfortunately, the traveler does not want to research these.
