Airblue services to Manchester, UK

Airblue flies between Islamabad, Pakistan to Manchester, UK, a distance of 3,326 nm according to gc.kls2.com/. From what I can tell, the only aircraft they have are A320’s and A321’s, neither of which have the range to do this route nonstop.

Considering the actual route flown, due to restrictions imposed by various countries, would be more than 3,326 nm and the A321’s range is about 2,600 nm for the -200 version, it’s obvious that the airline has to stop someplace enroute.

Does anyone know where the aircraft stops or do they just sacrifice payload for more range?
