When I board planes I wait until the last possible second - I like to hear 'last call' before I join the queues. I don't take stupidly big carry on luggage, so why would I care whether I get on first or last? I'd rather wait as long as possible and avoid being sat on the plane. This probably ruins carefully planned boarding procedures. C'est la vie. But as it stands, the trouble with boarding is that there are plenty of people like me.
