As recently as 2010, most airlines buying Boeing’s 777 for international flights opted for nine-seat rows. Now 70 percent of new 777s have rows ten seats across, Boeing said. This seating squeeze is likely to increase with airlines adding 5-6 additional seats per plane. Aisles are also getting narrower. Airlines insist they are making better use of space and travellers won’t notice. The result is an airline gets more paying passengers and a lower fuel bill because seats are also lighter, due to less padding. These changes affect US domestic and international routes.
