Jahangir Alom, 26, a failed police community support officer and territorial army soldier from Stratford, London, who travelled with Dart to Pakistan on their unsuccessful attempt to seek terror training was jailed for four years and six months.
Mark Topping, specialist counter-terrorism lawyer for the Crown Prosecution Service, said: "When Richard Dart, Jahangir Alom and Imran Mahmood were making plans for two of them, Dart and Alom, to fly to Pakistan, they did not expect those travels to lead them to the dock at the Old Bailey and jail.
