Ludwig my friend, not a great first post. I think that you are delusional. RTG means all doors closed. It is a regular occurrence to have the cabin doors closed with cargo/bags still being loaded. The closure of cargo and bulk doors is beyond the control of the FD crew. When the dispatcher comes to collect the final paperwork from the cockpit and asks if the cabin doors can be closed he is always asked how long will it take close the lower doors. The answer is always 5 minutes Captain, almost scripted. If I had a hundred dirhams for every "5" minutes I have spent waiting for the cargo doors to close I would have been able to retire years ago.
There is not one flight crew member that I know who would deliberately delay door closure unless there was a very good reason. RTG can and is often not met because we are waiting for missing passengers, technical issues or seating problems which once again is beyond the control of the crew.
I concede that there has been a significant improvement since the recent focus however laying the blame on the crew for not meeting RTG targets is simplistic and naive however symptomatic of an EK managers view of the operation. You wouldn't happen to be one would you ? If so can I suggest a bit more time closer to the coal face.
