One other thing is that the people should allow other people who are already ready to walk out pass them before standing and taking out their carry-on. Most times I've seen all passanger wait for each row taking out their carry-ons sequentially instead of 10 taking them out at the same time. If everyone would be me with a carry-on it'd take around 5-10m since I only take the aisle when I'm ready to leave and/or there is another person taking out their carry-on in front or behind me.
