Sooner or later, when things are not being done as they should be done, it is pointless to speak to anyone except the organ-grinder. It does senior managers no harm whatsoever to talk to angry passengers after a system failure which could have been avoided by better management.
I repeat; the problem in DXB that I posted about was Emirates miserable failure to recognise and deal with the problem in good time, ie when it become known that the departure from Manchester would be so delayed that connections would be missed.
On my workstation in the UAE in 1976 I could call up on our relatively primitive CRS a list of all connecting passengers aboard an incoming flight and their next/ultimate destinations, and start the ball rolling to arrange alternative flights, hotels, transport etc before a delayed service landed. Here we are, 40 years later, and Emirates still have to learn how to do that. Call me unimpressed.
