国内航班提前40分钟停止值机。航班起飞前40分钟停止办理登机手续且开始登机，起飞前15分钟舱门关闭。交通运输的高峰时段，建议最少提前1个半小时到达机场。值机，即登机报到手续，英文为Check-in，指旅客搭乘飞机前所需进行的手续。报到手续通常由航空公司或由地勤代理代为办理，负责查验乘客的旅游文件（包含护照及所需签证），协助托运旅客不愿或不得携带进入客舱的行李，并核发登机牌。

暑期旺季搭飞机最好比平时提早到机场，因为不少航班机位超额卖出，check-in太晚可能被放上「waiting list」，由于没有位子而上不了飞机。暑期航班一票难求，除了放假回国丶外出旅游的年轻人，还有不少父母家人陪同

飞机上check in意思是指办理登记手续的意思。飞机上的check-in, 表示办理乘机手续意思。比如帮助乘客进行行李托运、机上座位预定，打印登机牌；办理过程中需要客人出示的有效证件。（包括身份证、护照、军官证、士兵证、临时身份证等）
登机牌（boarding pass/boarding card）是机场为乘坐航班的乘客提供的登机凭证，乘客必须在提供有效机票和个人身份证件后才能获得，也有人称之为登机证或登机卡。
上个世纪80年代之前，我国使用的登机证印制十分简单，多为手工填写和加盖橡皮戳记。随着电脑技术的广泛应用，现在所有机场或航空公司都采用电脑打印。近年来，登机证的印制更加精美，背面还出现了不少广告内容，成为引人入胜的集藏品种。2009年4月8日，中国南航和中国移动合作，在国内率先推出了电子登机牌服务。如今，登机牌已采用国际通用的英文单式，图案更加丰富多彩。
