Aircraft boarding times could be cut by 25 per cent, according to a new study published in the Journal of Air Transport Management. According to researchers from Clarkson University in Potsdam, New York, allocating seats according to the amount of carry-on luggage could dramatically cut boarding times and save $10m (£600,000) a year. Professor John Milne and undergraduate student Alexander Kelly propose that those with the most baggage board first, then sit in the window aisle where they will be out of the way of the next passengers to board. Customers would also be seated so that luggage is distributed evenly through the aircraft. However, the researchers admit this method does not allow for customer preference, such as allowing families or other groups to sit together.
