Trying to use my own credit card creates problems. Department or individual Professors should get a travel card to charge suites and other arrangements for candidates.
Travel agents are too costly and a waste of time.
No written directions for checks, reimbursements, etc.and too much paperwork - rules seem to vary. It seems like nitpicking. The agencies don't seem compelled to give us good prices or service. I also get very bad service from United Airlines, so we shouldn't contract with them. Allow departments to make and pay for arrangements as part of their contract with the speaker.
