Antarraashtreey udaan se pahle antim taiyari ke liye jaach suchi jo dastavez, havai adda prakriyaen, suraksha, immigration, bhoj, paise aur yaatayat ko shamil karti hai. Vidiyo un vyavaharik kadamon ki soochi deti hai jo nikalne se pahle dinn aur ghanton me poore karne chahiye aur bataati hai ki udaan badalne ya der hone par kya karein.
