According to Al Jazeera, citing data published by Flightradar24 on X, while the nationwide U.S. departure ground stop was in effect, the service observed approximately 1,000 airborne flights bound for U.S. airports at the time of the post, compared to over 4,500 at the same time last week. This is a comparison of the stock of airborne flights at a specific point in time, rather than the cumulative number of cancellations for the day, nor does it imply that the approximately 1,000 flights are all international inbound flights or the current real-time flight count.
