You can still use it though, it's just single use. They told us on a recent flight where all lavs were completely inop to go in the terminal, and if more than 2 people have an emergency in flight, then there's going to be an issue.
Completely unacceptable.
Planes with no lavatories should be grounded until fixed.
I’ve never heard of any of this before, which makes me think airlines have recently figured out that they can just close lavatories instead of fixing them and everyone gets paid the same.
