Most consistant plane on a route
 

I was looking at a flight in just over a week from LHR EK2 and wanted to see what age range the planes were recently, I was quite supprised to see the same plane has been on rotation for most days, I don't think I have seen that before https://planefinder.net/data/flight/EK2 with A6-EUM apart from when it seems to be out for service I guess. Seems to be one of the few routes with a consistant aircraft which is rare considering usually you get a range of A380's

There's something very odd about A6-EUM.

It started off operating only EK77/78 to NCE every day, then only EK139/140 to PRG, and now EK1/2 to LHR.

It has occasionally flown to other places like MRU, KUL and MXP, but it mostly just sticks to the same rotation every day.

Someone once mentioned on here that it had to do with line maintenance certification requirements at the outstation as it is one of the minority of RR engine equipped aircraft.
