Questions & Answers about Saya akan pergi ke bandara pagi ini.
Ke is the preposition of motion toward a destination (“to”). So ke bandara means “to the airport.”
Di marks location (“at” or “in”), so di bandara would mean “at the airport.” If your focus is on being at the airport (not going there), you’d use di bandara:
- “Saya sedang di bandara” = “I am at the airport.”
For movement, always use ke.
