- 1機上的。機上餐、機上電影、機上雜誌。
In-flight means it is provided, or it happens, during a plane journey, while you are in the air. In-flight meal, in-flight movie, in-flight magazine, in-flight Wi-Fi: these are the usual companions. You will see the word on airline websites and on the cards in the seat pocket. It belongs to planes, not trains or buses. Though actually, watch the space. In flight as two words can just mean “flying,” as in a bird in flight, which is an older and wider use. The adjective that sits in front of a noun is the plane-journey one.
in-flight 形容在飛機飛行途中提供或發生的事，像是 「in-flight meal」、「in-flight movie」、「in-flight magazine」和 「in-flight Wi-Fi」。你常會在航空公司網站和座椅口袋的卡片上看到它，而且只用在飛機上，不用在火車或公車。
另外要注意，拆成兩個字的 「in flight」 意思比較寬，只是飛行中，例如 「a bird in flight」，是比較古老的用法。帶連字號、放在名詞前面的，才是指飛機旅程的那個用法。
From the word’s history
