Whatever the published Minimum Connecting Time , the reality is that allowing less than 2hrs anywhere isn't sensible. The mishandled baggage rate for transfer bags is vastly higher than for point to point so picking it up at LHR, AMS or wherever is much safer than checking it through.The time taken to get the bag off the aircraft to the terminal, security check it, make sure that the passenger is checked in and actually boards the flight , re-sorting it and getting it to the onward aircraft all takes time and there are gaps and delays/queues between each activity as well. The whole process is time-hungry and demanding of machine and people time and resources. Bags can keep arriving at the aircraft side up to and beyond the last minute but in the end it gets to a point where, rather than lose the slot the flight must depart even if there is still baggage at the aircraft side.Where labour is cheaper more manpower can be thrown at the task but in Europe where it is expensive and made more expensive by limitations on working hours, union agreements and so on there is a limit to what can be provided.
Allow 2 hours plus and all should be consistently well,- and you will have a more relaxed transit and time for a coffee and a walk around too. Your blood pressure will appreciate it.
