When you take a plane journey anywhere in the world, the cabin crew will walk up and down the aisles of the plane while it taxis on the runway. They'll make sure that nothing is blocking the aisles, but why?
One of the most dangerous aspects of air travel is the takeoff. Takeoff and landing is the when majority of problems occur. So passengers need to be prepared to depart from the air lane quickly if a problem occurs. Cabins crews on flights from Syracuse to Los Angeles
and in fact everywhere in the world are specially trained to get passengers off of a plane in super fast time in case of an emergency. Most important is that passengers are able to make a quick escape from the plane.
For this reason, whether flying domestically or catching flights from London to Pristina
, the aisles of the plane must be kept clear during take-off so that no-one trips over luggage or bags while trying to make a quick escape from a plane that has been caught in an emergency. It may be an inconvenience to have to push everything under the seat in front of you, giving you even less leg room than you'd have normally, but it's a safety procedure that must be adhered too.
For people who are sitting in the emergency rows it is especially important to keep the aisles and space under their seats clear. They cannot even put anything under the seat in front of them. People seated in emergency seat rows do get more leg room for the whole flights from Milwaukee to Toronto
, and as such they have to make other compromises.
Emergency row aisles must be kept entirely clear because those are the aisles that many passengers will not to use to escape the aircraft in an emergency.
