Flight cancellations typically lead to direct operational costs and can damage a company's reputation, potentially leading to a decrease in customer bookings and revenue. The anticipation of significant cancellations on Thursday adds to the uncertainty. This news is directly related to United Airlines and is likely to be of high importance to investors. The confidence level is not at 100 because the long-term financial impact will depend on the duration of the cancellations and the final outcome of the inspection process.
