JBLU is trading at $4.71, up 3.29% this morning following the airline's completion of required software updates on its Airbus A320 and A321 fleet. The carrier resumed normal operations after addressing an FAA emergency airworthiness directive issued November 28 related to solar radiation concerns affecting key flight systems. The stock gained nearly 2% on December 2 after the announcement, and momentum continues today as operational disruptions clear. While fourth-quarter demand remains healthy, the airline faced headwinds from the government shutdown (reducing ASM growth by ~1 point) and Hurricane Melissa in Jamaica, though these impacts are now being resolved.
