Some quotes

They persuaded the TSA to let them pay for a new system. They shelled out $4 million for new staff and $1 million for a new system for screening and scanning. Again, Delta paid for everything!

The results: pure magic! I’ve now been through the new system five times and each time it has been smooth and quick. Delta speculated that they new system would improve efficiency by 20-30%. My experience suggests that it is closer to 90%.

Everything about the history of humanity suggests that something fully controlled by government is going to go wrong, but in a moment of panic, Congress decided to forget all lessons of history and do something spectacularly stupid.

Is this a kind of surreptitious privatization? In a word, yes. It is happening without legislation and without big headlines. But it is vastly improving the lives of millions.

It's not actually that big of a deal, 5 lines compared to one and a automated roller compared to one where you have to push yourself through. It's interesting to me THAT costs 4million+++ in one place :D pure genius :|
But yes the TSA hadn't done that for 10 years or so the hadn't even moved :D
