Partner texted around 10PM saying he's on his way home and didn't come back until after 2:30AM. No explanation. How to deal with the situation?

What would you do if your partner texts you around 10PM saying he's on his way home, mind you we leave in a place where there's barely any traffic and it takes max 30 min to get to one place to another, but doesn't come home until after 2:30AM. I pretended I was asleep because I didn't want to make a scene that late. Then around 7AM he leaves for a flight on a one week work trip. I'm not planning to text or start a conversation or even address the issue over the phone. I'm trying to stay calm and collected even though I'm livid and fuming inside. How to deal with this situation and how should I behave when he returns from his trip?
