29E.97 关于及时提交文件和航空旅行提前订票的遵守情况资料见表 29E.17。日内瓦办事处继续尽一切努力全面遵守预购政策指示，并已采取若干步骤，努力确保提高提前预订机票的执行率。这些措施包括发布备忘录，提醒工作人员和核证员应承担的责任，并要求核证员记录推迟核证和(或)旅行者推迟提交的原因。最近又采取措施，将不符合 16 天期限要求的旅行申请交由行政司司长作最后审核和批准。尽管作出了这些努力，但仍有一些情有可原的情况导致旅行申请在 16 天期限内提出。
29E.97 Information on compliance with regard to the timely submission of documentation and advance booking for air travel is reflected in table 29E.17. The Office continues to make every effort to fully comply with the advance purchase policy directive and has undertaken a number of steps to try to ensure the implementation rate for advance booking of air travel is improved. These include issuing memorandums reminding staff members and certifying officers of their responsibilities and requiring certifying officers to record a reason for the late certification and/or late submission by the traveller. Most recently, additional measures have been introduced whereby travel requests that do not meet the 16-day deadline are routed to the Director of Administration for final review and approval. Despite these efforts, there continue to be mitigating circumstances resulting in travel requests falling inside the 16-day deadline.
