"Have a safe flight." in 한국어. The situation is a bit different. A Korean friend of mine is coming to KL, I mean, the city where I'm living now. I'm trying to tell him sort of "Have a safe flight to KL" in Korean. He is not coming to travel, so the sentence shouldn't have the phrase "여행", and he'll not be going back Korea in short term due to some reasons. So how the greetings should be? If possible, I'd also like to know how to say "Don't worry. Everything will be alright." Is "걱정하지 마세요. 만사가 잘 될 거예요" okay? Thank you.
