On the A320, Acro Aircraft Seating came up with a configuration giving an extra inch to the middle seat but keeping aisle and window seats at 18 inches wide. The extra space comes mostly from making the center aisle a bit narrower.
Acro says 80% of its deliveries for Airbus planes the past two years have had the wider middle seat. “It’s become our baseline product,” says Marc Westcott, Acro’s key account manager in the U.S.
Air New Zealand says passengers are noticing. “The slightly wider middle seat helps balance out the fact that the window and aisle seat customers enjoy a greater sense of space,’’ says Anita Hawthorne, Air New Zealand’s general manager for customer experience.
