The first chart below compares the nationwide TSA passenger count for the same dates in 2019 and 2020. The second chart shows the decrease by week in daily operations at Lindbergh Field. This chart shows that currently there are about one-third the number of operations there were before the virus hit. Putting charts one and two together and assuming the nationwide passenger count is similar for San Diego, then the average load factor per operation is down from about 84 percent to about 15 percent.

More to come (Graph updated 5/5/2020) and yes, the graph is correct. In one week, we have seen a decrease in number of operations on the first Monday from almost 650 to 290. Wow. Today's comment, Oh my! The second graph shows the change in the number of operations to and from different states. The negative sign indicates a decrease in flights. The next chart shows the summary of operations by week.
Today is Sunday, so in the next day or so, we will see if the number of operations continues to decline, or the airport has hit bottom. There are numerous reports that the coronavirus may have a profound and lasting effect on the airline industry. Airlines announced that they will not be purchasing new aircraft until 2021. Flights will not be restored to pre-coronavirus levels for some time. And some airlines are dumping larger aircraft for midsize planes.

What is amazing about the data in Figure 2 is that the number daily arrivals is now less than 100. A missed approach is implemented for safety, but too many missed approaches might demonstrate a chronic issue.
