Do-it-yourself airport gates

Who needs a gate agent to take your barcoded boarding pass and scan it before you walk down the jetway to your plane?

That's the question Las Vegas officials asked themselves. Their answer? Replace the gate agents with automated turnstiles. Let the passengers scan their own boarding passes, just like self-service check-out lanes at the grocery store. (Obviously, this process would happen after passengers have already passed through the security checkpoints.)

McCarran Airport's new Terminal 3 project is expected to debut the hight-tech turnstiles when it opens in 2012. If successful, you can be sure the cost-saving measure will be applied by other airports.

Meanwhile, for arriving international passengers, McCarran Airport is already introducing a do-it-yourself passport control kiosk.

Pretty soon we'll be flying the planes ourselves.
