Some airlines are telling passengers that new security regulations prohibit them from leaving their seats beginning an hour before landing.
Air Canada said in a statement Saturday that new rules imposed by the Transportation Security Administration limit on-board activities by passengers and crew in U.S. airspace.
The airline said that during the final hour of flight passengers must remain seated. They won't be allowed access to carry-on baggage or to have any items on their laps.
Flight attendants on some domestic flights are informing passengers of similar rules.
