Why do airlines sit their planes from front to back instead of back to front?
gpt
First class and business class seats are in the front, so they seat those people first so that they don't have to be in line at the terminal, and have time to stow away their belongings and settle into their seats. Then elderly and mobility impaired get priority seating. Then the rest, usually front to back, but efficiency studies have shown that random or window to aisle is more efficient for loading (people don't block the aisle, preventing the rear of the plane from loading), but the system of calling out the order at the boarding gate becomes more difficult with this method.
