I have flown 8 outbound and 7 inbound international flights through ZIA in last seven years. The airport checking-in and immigration layouts have been remarkably improved during last two years. The departure portion is now comparable to most other international airports. The new parking structure attached to the main terminal is a great job done. The arrival portion is still messy specially outside the airport. Placing transparent glass between the baggage unloading people and the baggage claiming passengers has also reduced the baggage cutting (stealing) disasters. Thanks ZIA. We would like to see more continuous improvements.
