Has anyone flown from Canada to the US in the past month? Wondering what the situation is with carry-ons. I'm headed to Toronto and Ottawa this week and trying to figure out how light to pack. I'm returning from YYZ to CVG and usually have a small rollaboard (about the size of a pilot's bag) with an LCD projector and a laptop-sized tote bag with my small purse, laptop and paperwork in it. Will I be able to take them both thru security? Thanks for any insights.
