“祝你一路平安”英语怎么写？

wish you a nice trip
但通常用have a nice trip就行了nice 可以替换成其他很多形容词例如good,wonderful

老外通常不会祝你旅途平安，通常会祝你旅途愉快，一般用nice就很妥当

Happy landing.
Have a nice journey.
Have a pleasant trip.
Have a good trip.
Have a great trip.
Have a happy landing.

Have a safe trip/flight.一定对的哟！

Have a good travel

wish you a smooth journey
