突發情況：安檢設備故障、航班登機口變更等突發情況可能進一步延長時間。 

3、高峰時段的額外挑戰 

人流密集：節假日、早晚高峰時段，機場人流密集，值機、安檢和登機都可能排長隊。 

交通擁堵：前往機場的路上可能遇到交通擁堵，延誤到達時間。

航班集中：高峰時段航班起降頻繁，可能導致值機和安檢流程更加緩慢。

4、國際航班的特殊要求 

邊檢和海關：國際航班需要額外的時間辦理邊檢和海關手續。 

簽證檢查：部分國家要求檢查簽證或旅行文件，進一步增加時間壓力。

二次安檢：部分國際航班在登機前需要進行二次安檢。 

三、小貼士：如何高效利用時間？ 

提前準備：在家完成網上值機，并準備好所有旅行文件（如護照、簽證）。 

輕裝簡行：盡量減少托運行李，節省柜臺辦理時間。 

使用快速通道：部分機場提供付費快速安檢服務，適合時間緊張的旅客。
