Refinitiv market analysts say oil fell after a temporary US‑Iran peace agreement, creating scope for airlines to save tens of billions on jet fuel while passengers are unlikely to see immediate relief as tight capacity lets carriers keep fares well above pre‑war levels. In the US, ticket-price gains have lagged fuel-cost increases and domestic seat growth remains limited, leaving carriers room to use lower fuel costs to rebuild margins rather than reverse recent fare hikes. Spot jet fuel was $2.

Refinitiv market analysts say oil fell after a temporary US‑Iran peace agreement, creating scope for airlines to save tens of billions on jet fuel while passengers are unlikely to see immediate relief as tight capacity lets carriers keep fares well above pre‑war levels. In the US, ticket-price gains have lagged fuel-cost increases and domestic seat growth remains limited, leaving carriers room to use lower fuel costs to rebuild margins rather than reverse recent fare hikes. Spot jet fuel was $2.85/gal on June 17, down from an April peak of $4.88/gal; if sustained, that decline would cut annual US industry fuel bills by more than $40 billion.
