搭飛機時間的問題?

Time different between Hkg and Tokyo. If Hkg time are 01:00 , Tokyo time will be 02:00. Flying time Hkg to Tokyo will take around 4hr 10min and Tokyo to Hkg will take 4hr 30min if using same Aircraft .
So if you ask why around 1 hrs different. it was time different. But if you check exact time will be only 20min different for Air route and head wind

另外有季節條件,冬季及夏季都會出現不同的來回時間.原因是冬季飛機南下會遇上強烈的逆風.(接近地面是北風,但高空就吹南風.)出現夏季往日本差十幾分鐘,冬季就相差1小時以上(而那十幾分鐘是因為回程走外圍,類似跑步走外圈距離多了}.

只不過係順風同埋逆風既問題．順風當然快 D. 好似我經常來往溫哥華咁．去程１１小時多 D ka 咋．回程往往要１３小時有多 ka.

係航線的問題, 去到返來飛的路唔同
所以返來要耐D
