Which bits are barking?
Are you advocating calling for push and start before being ready now " to attempt to keep the schedule" Interesting idea, maybe call as you get the bus to the aircraft just to be sure, to be sure.
Strangely enough all the other BRS operators also have schedules to keep and it is only one operator who consistantly shows a lack of professionalism in calling for start when not ready, often holding up the others.
If they are happy to show this lack of awareness to the rest of the world, imagine what happens in the confines of the flight deck.
