The rescheduling of the LAX
flight was part of an overall rescheduling effort by KLM with the main purpose increase overall aircraft utilization rates, increase the number of arrival and departure banks by one, reduce the congestion at SPL, and eliminate certain weak and delay-prone elements in the previous schedule. The new schedule took effect with the commencement of the 2006 summer schedule at the end of March.
In the case of the KL601/602 AMS LAX AMS
rotations, the flight was pushed back by 2 hours and has also an extended ground time at LAX
(2h40, where KLM's standard for B74E ops calls for a 1h50 outstation ground time). The flight operates roughly according to the same pattern as the KL685/686 AMS MEX AMS
rotation and no longer as the KL605/606 AMS SFO AMS
rotation, which was left more or less unchanged. The extended ground time at LAX
should provide for a more stable operation, although the first statistics indicate that the KL601/602 is now less punctual than before.
