What are acceptable justifications for use of non-contract carriers?
>There are three acceptable justifications for use of non-contract carriers: • Space or flights not available in time to accomplish mission, or contract flights would entail overnight lodging and an increased overall trip cost • Contract flight schedule conflicts with Agency policy requiring travel during business hours (if applicable) • Non-contract carrier offers lower publicly available fares which result in lower overall cost of trip (considering total of all trip expenses).
