Due to revamped menus and promotions, the approximately 6,000 North American locations of Subway attained a 13 percent average growth rate in same-store sales compared to the first nine months of 2021.  Growth was especially evident with customers buying grab-and-go sandwiches at airport, college campus and hospital locations.

In commenting on the improvement, Taylor Bennett, VP of Non-Traditional Development at Subway stated, "as we focus on strategic and profitable growth, there is a significant opportunity to expand our footprint in non-traditional locations and for franchisees to generate incremental revenue for their businesses". Subway intends establishing sandwich centers in convenience stores, hospitals and airports.
