To clinch the deal, the manufacturer guaranteed the airline a 20% reduction in seat-mile costs over the standard Trident 1E. This modified Trident 1E was dubbed the Trident 140 and featured a 1500 pounds higher gross weight and more powerful engines than other Trident 1/2 variants, stronger floors and additional emergency exits to make it suitable for Channel's European IT operations in a high-density seating arrangement.
