HRG-MAN is 2240nm. Before the sanctions bmi used to operate a 321 daily from Tehran to London (2393nm) which was not immune from tech-stopping, especially in winter. However, bmi's A321s had an additional extra fuel tank giving a total capacity of around 21 tonnes (or 21.5 on some of the fleet on a good day). The standard A321 which is what I suspect Monarch operate has a capacity of 18.6 tonnes, which is a difference of about one hour's flying time.
