Makes sense. Personally whenever I issue a hold into OMDB I just read the delay time off the screen be it 5 or 50 minutes as it saves the obvious question as to how long. Also allows me to mentally plan is a long leg length is available when that question follows.
As for delays, has the Emirates internal 'flow' control kicked in yet? I read on here it was to start soon. Winter is right around the corner and the delays are already 40+ of a night time.
