The airline sector is trading higher, with the JETS ETF up 2.34%, following a strong quarterly earnings report from Republic Airways (RJET). The regional carrier announced Q3 revenue and profit that beat expectations and raised its full-year 2026 earnings guidance. This positive outlook is likely outweighing concerns about high fuel costs, which were highlighted in Frontier Airlines' reported loss for the same quarter. The market appears to be focusing on signs of resilient demand and strong execution within the industry.
