This whole Bad ID Ban is often referred to as revenue protection for airlines. I'm beginning to think it is revenue enhancement for Greyhound. The largest group majorly affected (as in actually changing their life styles, not just counting the time wasted and the constitutional/civil rights violations for 2 million pax per day ) are illegal immigrants with no documents. They can no longer fly domestic and will have to take the bus. This will cause airlines to lose revenue from good cash paying customers. Good work TSA.
