What's the French term for "empty seat" in the context of "There's an
empty seat at the dinner table?" or "We have one empty seat left on
the airplane"?

Hi mmoffatt,

In this context, the best translation for "empty seat" would be "place vide". 

Search strategy:
I asked my brother-in-law, who is a fluent French speaker.


I hope this is helpful.
