It's important to have high technology and modern installations in our nation's airports. Not only is this necessary for security, but also for smooth operations of airlines. No one likes to be delayed or to have their baggage damaged or lost when traveling. Having modern, rennovted airports can help to prevent these problems.
I'm a frequent flyer and some of the large airports have some pretty big issues. The amount of time that that flights are delayed and gates are changed with little or no notice is completely unacceptable. I can't believe how badly it seems that one error or late flight can cause such a giant ripple effect of issues for other flights.
