从Changi Airport的网页上看到"passengers are advised to check-in at least 2 hours before flight departure time".请问最迟的check-in时间一般是起飞前多少分钟？多谢了！

旅行社的人跟我讲，最迟一个小时之前要到机场check-in。不过那是新航，其他航空公司的效率有没有那么高就很难讲了。你可以去changi airport看一下它的international flight check-in 几时停止，那就是最迟check-in的时间。

后来还是赶上了,没什么问题,因为那时候已经没人check-in了,所以会比较快

不过有时候有一张票卖两个人的情况发生，所以早去一个小时左右为好。

To be save, go to the airport at least an hour in advance...

Anyway... the latest I encountered was about 25 minutes before the flight took off, and there were still a couple who were 5 minutes later than me. (United Airlines, to Hong Kong)
