It comes after one customer in Australia measured the size of his sub and, after finding it only measured 11 inches, posted pictures of it online. The story went viral, and since then, a number of consumers in the US have filed lawsuits against the international chain, including one for $5m, according to The Times.
It has been reported that Subway initially defended the size difference, saying that the ‘footlong’ tab was branding, and didn’t necessarily mean the sandwich was that length. However, this has prompted allegations of false advertising.
A spokesperson for Subway UK & Ireland, said: "We cannot comment on the suit that was filed as we do not comment on pending litigation.
"For 47 years, customer satisfaction has been our top priority. We regret any instance where we did not fully deliver on our promise to our customers. We freshly bake our bread throughout the day in our more than 38,000 restaurants in 100 countries worldwide, and we have redoubled our efforts to ensure consistency and correct length in every sandwich we serve.
"Our commitment remains steadfast to ensure that every Subway Footlong sandwich is 12 inches at each location worldwide."
