Your link doesn't mention AF1, it merely says "Pelosi used the Air Force aircraft for a total of 85 trips" at a cost of  $2,100,744.59 over a two-year period.

Not mentioned was any reference to travel between the Capitol and Nancy's district, San Francisco. Those trips appear to have been official business, for instance, "For example, purchases for one Pelosi-led congressional delegation traveling from Washington, DC, through Tel Aviv, Israel to Baghdad, Iraq". So that trip at least was to foreign nations that the Speaker of the House would be expected to travel to at public expense.

To reiterate: No mention of personal travel. Your source claims $1.05 million cost per year of travel for Nancy's official business, compared to $60 million per year for Tronald Dumpster's personal weekend getaways to Mar-a-Lago. Not comparable in any way including purpose of transportation. Tronald's is for leisure, Nancy's were for official business.
