可以提早到機場辦理check-in嗎?

係機場黎講... 國泰/泰航 係全日都可以做到check-in... 而其他航空公司好多都係起飛前2~3小時開始check-in...
而係機鐵(香港/九龍站)呢... 有得係 機鐵站check-in既航空公司都可以全日check-in...
例如你坐夜晚機既... 係機場你要去到起飛前2~3小時check-in... 而係機鐵站就可以比你起飛果一日上午起check-in...
所以如果你唔係坐 國泰/泰航 而又想早4~5小時check-in... 你就要係機鐵站check-in... 之後你想入機場可以入機場, 完全唔係問題...

depends on which airline you're flying. you can check-in at airport earlier if you're flying CX.

for others, you can think about checking in at Airport Express.
