I have heard the baggie sizes vary from country to country.

When I recleared security in Frankfurt Monday morning (the day all this baggie nonsense kicked in across Europe) the screener discovered the small case of things I thought I had forgotten. Apparently the Canadians didn't see it on the xray. She very patiently pulled out a bag and she put my Tide to Go, lip balm, etc into it. I would say it is 9 inches by 6 inches. Then she didn't xray it or anything, it was strictly a way to determine total liquid volume.

The various liquids I had acquired post security in Toronto and not yet finished, or in some cases opened, she took. Each was over 100 ml and therefore gone. Damn, I wish I could have stayed airside somehow for the transfer! I was thirsty as hell by the time I made my (very tight) connection, had no time to get euros, and got nothing to drink until about two hours after that screening.

One other thing: as I was packing up, the screener next to her told the man after me "you need a bag for these sir, you must go back out and line up again, you need a bag" over and over and the poor man didn't understand her, and my screener tried to say "I have bags" but the other screener was deep in "don't talk to me I am explaining something to a stupid foreigner" mode so my screener finally pulled out a bag and handed it to the man. Heh. Both good and bad screener behaviour exists in every country.
