I have no problem with their current system and never bother with speedy boarding. Looks like they are changing stance on hand luggage though: last flight they were telling us that small bags and coats should be on the floor, to leave room for the bigger bags in the overheads. I guess fast turnaround means they wish to discourage hold luggage but I have no wish for the overheads to be rationed with preference to the over-packers !
