The largest expansion project in terminal history, the Buffalo Niagara International Airport underwent an extensive upgrade which saw multiple additions, new entrances, new baggage claim systems, upgraded concessions and a new passenger meet-and-greet area.  The design improved security, pedestrian congestion, and baggage claim capacity.

Four brand new state of the art baggage carousels were installed to meet the latest TSA guidelines.  The new additions on the east and west wings of the terminal allow for better egress for arriving passengers.  The east addition includes a large greeting area to welcome home travelers.  It has a living green wall with LED lighting to aid in the growth of the plants.
