The Iran War may push airfares higher and lower, forcing airlines to rethink how they make money per seat. Major U.S. airlines are already expanding premium seating faster than economy, with business and first-class seats increasing 27% since 2020 compared to only 10% growth in economy. This shift allows airlines to offset rising fuel costs but also leaves less room for traditional economy passengers. The shift is seen as a subtle but important shift in airline economics.
