DR
We cannot legitimately cal 'ready' if the airbridge is still attached to the aircraft.
At AMS for eg. you must pushback within 2 mins of clearance or that clearance WILL BE CANCELLED. Hard rules, I know but it's fact.
Tell us how to get round these problems if you have an answer but please don't just say it should be a 2-way street when, from our side, it's often a one-way cul-e-sac.
WE WANT TO HELP BUT OFTEN WE CANNOT!!!!
