A set farewell phrase wishing someone a good trip. Often used when seeing someone off on a journey.
See also: 良い旅を

空港で家族に「良い旅行を」と声をかけた。

Synonymous variant using 旅 (tabi) instead of 旅行 (ryokō); both mean 'have a good trip,' but 良い旅を may sound slightly more literary or poetic.
A fixed phrase composed of 良い (good) + 旅行 (travel) + を (object marker), literally 'a good trip.' The verb (e.g., して, 楽しんで) is omitted, as is common in Japanese well-wishes.
