Govt shutdown and flying

My DH is to land within the hour across the country. The airport here was VERY crowded when I dropped him off VERY early this morning. He said the TSA was not a problem this morning, and I am not sure how “real time” flight aware is, but it showed about 25 or so minutes from being listed as “taxiing to the runway” to taking off. DK if this is “normal”, how many planes were ahead of his or if they were spacing out flights (arrivals and departures).
