Below are some photos of the new addition taken this past weekend. Hard to describe, but this is a drastic change to how the airport feels. It used to feel very small walking up the low, dark ramp and right to the gates. This makes the airport seem much larger, and not so regional. I've gone through a couple times now, and each time, travelers were commenting. It was also busier one of the days, and they opened an additional security checkpoint (they can open or close doors visible in picture 1). Not that it is ever hard to get through security, but passenger throughput is improved. There is a dedicated TSA PreCheck lane, which is convenient. The new starbucks after security is a nice addition, and will not replace the existing location. There is ample room/seating after security to put on shoes/belts/etc. I did not go into the Grand Rapids gift shop, and the restaurant/brewery is still under construction.
