MCI is a medium hub in Passenger Index's FAA-style classification: it handled 0.7% of national TSA checkpoint throughput in the 12 months to September 30, 2026 (0.25% to 1% is the medium hub band). The FAA's official hub classes use calendar-year enplanements, so they can differ slightly.
No. MCI is not one of the airports in CBP's Airport Wait Times data, so there is no international-arrivals figure. The departing figure still counts passengers bound for international destinations, because TSA screens them like everyone else.
Not from this data. TSA screening does not record where a passenger is flying, and CBP counts international arrivals only, so there is no international-departures figure to subtract. The two series measure opposite directions and are shown side by side, never added.
Airports usually report enplaned plus deplaned passengers, counting every arriving and departing passenger including connections. TSA counts departing passengers once, at screening; arrivals and connecting passengers who stay airside are not screened again, so this measure runs well below airport-reported totals, especially at connecting hubs.
