As of March 2010, Airplane Airways allowed passengers to bring one carry on backpack and one personal item into an Airplane cabin. Personal items include purses, baby bags, briefcases, laptops and assistive devices and are not counted as carry-on items. Smart travel bag is stored under the seat or in the overhead compartment as a safety precaution during takeoff, flight, and landing.Carry-on baggage size restrictions are in place at check-in. Carry-on items that don't meet Airplane Airways measurements need to check in.
