Landmark Aviation’s FBO at Piedmont Triad International Airport (GSO) in Greensboro, N.C., has seen an increase in business since its opening in May following a $2 million renovation, according to the facility’s general manager. The remodeling effort encompassed structural changes to the building and introduced a new more spacious passenger lounge, VIP lounge, a new bistro and a conference room. The upgrade included new paint, flooring and furniture throughout the entire building.
