I bet that doesn't count against any managers KPI...So no problem
WRONG!
It does count against a manager's KPI.
The problem is the airport managers want the aircraft off their ramp asap, on time.
SO, oversized bags get to the gate, the boarding CC gets no support from the ground staff, the bags make it to the aeroplane, so no delay down to airport staff.
It now becomes the aeroplane's problem, and the delay goes down to the aircrew (as the pax have boarded IAW with airport ground timeline), the ground crew close up the hold, then it's left to the CC to offload the bag, and have to explain to the passenger that the oversized bag will not go into the hold, and will be sent on the next flight.
Funnily enough, the local ground manager or team leader is usually not anywhere near this scene, and so the CC and the CM are left to deal with the irate pax, and then have to cop dirty looks (or worse) for the duration of the flight. Some have the balls to do so, others don't have the stomach for the extra grief.
The flight ops management get stung for the delay, and it affects their KPI - so then all the most minutae of details are scrutinised to see where a few seconds can be shaved off preparing the aircraft for flight can be found, including unrealistic timelines that aircrew have to work through in order to avoid an email asking to 'please explain' why their ship was 2 minutes late off the blocks.
Oh, and don't get me started on verifying that the actual weights in the OH lockers are not in exceedance of the locker weight limit - apparently, to monitor that with scales at every gate, would require 'costly' calibration and verification to each scale as they are deemed 'commercial'. Conveniently, the only system in place to 'monitor' this is - standard weights.
