Our Sop's dictate that we leave the crew briefing centre (CBC) 1hr 10 (or is it 1h15) before STD, at aircraft 50 mins or so to go, depending on where it's parked.
We generally get to CBC at 1hr30 - 1 h45 before STD, the best part tho' is that the duty period starts 1hr before STD, ie what the flight time limitations are based on . Yup , our duty period starts after we are on the bus to the air plane. Cant quite get my head around it.
To be fair we do get picked up and taken to work ,which in itself is great , but it would appear to be as much for the companies benefit as it ours.....less pay, etc , less reason to complain as someone else is doing the driving so we don't get so tired... although the standard of our drivers is , well, um, er , lets just say the drive is the most stressful part of the day...
This is for long haul B777, A330/A345/A343, you can work out the company from that...
