Airlines canceled and delayed flights on 29 November 2025 after aviation authorities found a software problem in Airbus A320-family aircraft. The issue became known after an incident on 30 October 2025, when a JetBlue flight from Cancun to Newark lost altitude and landed in Tampa. Investigators said solar radiation may have damaged data in the flight control system after a recent software update. Aviation agencies ordered airlines to install a new update for more than 500 aircraft in the United States. This happened during a busy travel period. Airlines in Japan, Europe, India, and the United States prepared for delays while engineers worked to fix the problem.

Airlines said engineers could complete the update during normal maintenance times. American Airlines reported that more than 200 airplanes needed the reset, and All Nippon Airways canceled 65 domestic flights. Delta, United, and Air India said only a few flights were affected, and Hawaiian Airlines stated that its fleet had no issues. Aviation experts said the A320 family is used around the world. They added that digital systems and careful monitoring are important for safe flights. Experts also said that timely repairs help prevent future risks and support stable operations for airlines during technical problems.
