Twin America, a joint venture half-owned by Stagecoach, has been hit with an antitrust lawsuit brought by attorney general Eric Schneiderman and the US Department of Justice.
The lawsuit alleges that the hop-on hop-off bus tour company has raised prices 10 per cent since two firms were merged into the Twin America company.
Schneiderman said: “The iconic double-decker Gray Line and City Sights buses are seen all over New York City but few people know they are a monopoly that has led to higher prices and less competition. Visitors to New York deserve better.”
Stagecoach said it “fundamentally disagrees with the allegations”.
