When there is a need to travel overseas, MOD charter aircraft will be used where possible. When this is not available, overseas travel will be arranged through Hogg Robinson Travel, under contract to the MOD, to ensure the best value for money is obtained. However, this is not exclusive, as overseas travel may be included as part of a training course or privately arranged at very short notice.
There is no requirement to account for the rank of brigadier or equivalent and above separately and to do so would require a manual search of records thus incurring a disproportionate cost.
Greater use of video and telephone conferencing is being encouraged to reduce the time and money expended on overseas travel.
