I was just thinking about this lastnight; I don't fly often, but next time I do, I'll be paying attention to which plane is actually used and avoiding the max.
I've never paid any attention to the plane model before.
Boeing fucked up pretty big with this plane if even those that pretty much never fly are thinking this way.
But is the option to filter by plane model itself new?
If you're adding a filter so people can avoid a certain plane, it makes sense to add more than one model of plane.
