I’d imagine Smuggling is going to be a big one. Likely via Airline, and Airport staff as they aren’t always subjected to the same screenings as the general population. Probably some TSA guys as well. Especially in areas with immigrant heavy populations.
Espionage will likely be a close second. Given many Airports also include Hangers and Facilities for the Feds, State and Local Law Enforcement as well as the Military. As well as major Aircraft manufacturers

I bet a lot of illegal alien terrorists cells travel from point around the U.S. too!
