However, air transportation is the most expensive mode of transportation, especially for the short-haul routes, say in Europe, where the economic cruising speed cannot be achieved. 但是,空運是最昂貴的運輸方式，特別是短途航運，比如在歐洲,空運根本無法達到經濟航速(指飛行距離太短)。

然而，空運是最昂貴的運輸方法，特別是短途運輸，以歐洲為例，實現最省經濟燃料的的飛行還不能夠實現。

然而空中運輸仍是最昂貴的運輸類型，尤其是短途運輸。以歐洲為例，經濟省油的飛行速度尚不能實現。
