Until people stand up as one and say enough is enough there will be no changes. A two week boycott of all air travel will quick bring this to a head and force some real change.
The problem with that is business travel will never join a boycott. When my boss says fly, we fly. I would much rather drive to Nashville or Chicago (each doable in under six hours for me) but they want us back the next afternoon or sometimes the same day (an incredibly exhausting pain.)
