However, JetBlue faced challenges due to two significant winter weather events in January and February, which resulted in a reduction of year-over-year capacity by approximately 3.5 percentage points compared to initial expectations. These disruptions also led to an increase in year-over-year costs per available seat mile (CASM) excluding fuel by a similar margin. Despite these setbacks, the airline experienced a two-point benefit to its first quarter unit revenue as a result of these events. Without the adverse effects of the weather disruptions, the midpoint of the first quarter unit revenue guidance would have improved by two points, and the midpoint of the CASM ex-fuel guidance would have improved by one point compared to previous forecasts.
JetBlue has provided updated investor guidance for the first quarter ending March 31, 2026. The airline anticipates a year-over-year decrease in available seat miles (ASMs) of between 2.0% and 1.0%, while operating revenue per ASM (RASM) is expected to increase by 5.0% to 7.0%. The CASM ex-fuel is projected to rise by 6.5% to 7.5% year-over-year, with fuel prices per gallon expected to range between $3.01 and $3.06.
In addition, JetBlue announced that its executives will present at J.P. Morgan's Industrials Conference on March 17, 2026, at approximately 8:50 a.m. ET. The materials for this presentation will be included as an exhibit to the Form 8-K filing. This update reflects JetBlue's ongoing efforts to navigate the challenges of the airline industry while maintaining a focus on operational efficiency and customer satisfaction.
