An anonymous reader excerpts from an AP story as carried by Yahoo News about changes stemming from yesterday's foiled bombing attempt of a Northwest Airlines flight: "Some airlines were telling passengers on Saturday that new government security regulations prohibit them from leaving their seats beginning an hour before landing. The regulations are a response to a suspected terrorism incident on Christmas Day. Air Canada said in a statement that new rules imposed by the Transportation Security Administration limit on-board activities by passengers and crew in US airspace. ... Flight attendants on some domestic flights are informing passengers of similar rules. Passengers on a flight from New York to Tampa Saturday morning were also told they must remain in their seats and couldn't have items in their laps, including laptops and pillows." The TSA's list of prohibited items doesn't seem to have changed in the last day, though.
