The solution to airline troubles:

Deregulate. Remove screening from federal control. Remove federal support and regulations for airline liability. Currently federal regulations limit airline liability.

I guarantee in 2 years, there will be private screening that is more effective and less intrusive all done by private airlines.

Their incentive would be lawsuits if they miss someone being screened.

Also, remove federal regulations for carrying guns on airlines, let private airlines determine requirements for letting them on.
