Boeing had another weak month for aircraft sales in May, taking orders for just four new planes. The company said Tuesday that it got no new orders for its best-selling jet, the 737 Max.
This shows that there must be actual problems with their aircraft though because airlines are not going to care about public attitude, due to the company's politics. But if they are genuinely unsafe vehicles or have the potential to be unsafe vehicles, then they'll stay away.
If public attitude ever got significant enough that they couldn't fill a certain model of plane they would definitely stop buying them, that said I'm not sure we're at that point.
