This is something we are very excited about. People love it because they don't have to worry about checking their bags. They get through the airport more quickly, and they use the airport's slot machines more, so there's a benefit for us.

We've seen about 70 percent read accuracy when scanning bar codes on bags traveling down a conveyor. With RFID, we are getting read rates of about 98 percent. We recently resolved the problem of having dead or quiet tags enter the system, so the read rates should get up to 99 percent.

We offered off-site check-in before 9/11, but the Transportation Security Agency shut it down after 9/11.

People start to worry that something may have gone wrong, and I think the doctors involved should give the people a regular update so they can be reassured.

What that, in essence, says is that you're not going to worry about the biggest disasters that could occur, you're only going to worry about the smaller ones,

I worry about the stigma -- especially in rural areas.
