The model is over 1Gb, so it takes a while to load and run - please be patient. There are five pages. Please click the double-headed arrow at the bottom right for optimal viewing on your monitor. US airlines have an average cancelation rate of 1.7% Regional aircraft have much higher flight cancellation rates Even with a massive spike in 2024 for the MAX 9, at 1.3%, it is better than the 1.5% at Airbus For Airbus, among its newer models, the A220-100 looks like a problem. The A330-900 is also a concern. For Boeing, the problem is the 737-700 (73G), as one might expect, given its cycles and age. This, of course, speaks to the problem with the delayed MAX 7. Another issue is the 787-8, with the highest cancelation rate among twin-aisles.
