Thousands of flights across the United States remained affected on Sunday as aviation disruptions stretched into the weekend, according to a First Squawk post. The report did not specify exact flight counts, affected airlines, airports, or the cause of the disruptions. The event matters because large-scale flight cancellations and delays can weigh on airline revenue and operations while disrupting travel and cargo schedules. What to watch next is whether carriers and authorities disclose the number of canceled or delayed flights and confirm when normal operations resume.
