點解飛機來回程時間不一

應該係氣流問題啦, 順風同逆風, 同埋航線, 仲有天氣都好影響到個航空時間的

The flying time difference in outbound and inbound flights is because there is jetstream . When flights fly parellel with the jetstream, the jetstream increases the aircraft's speed, so it arrives using less time needed.

However, when the aircraft encounters the huge jetstream blowing directly opposite of its direction,the aircraft slows down and uses more fuel.

氣流 (風/Jetstream), 航道, 機種.
地球自轉 - 沒有關係 (包括歐洲的旅程)

地球自轉關係.hong kong飛往europe所需時間一定比回程長

應該係氣流問題啦

因為行嘅路線根本不同
航空線並不同我們陸地上一樣啦
所以我們都不會在天空上看到有第二架飛機

可能係佢地既飛行路線唔同 OR 唔同機種
