The TSA issue doesn’t have anything to do with illegals. Mouth breathing, knuckle dragging, human drones who require non-stop supervision. The further away from the border they are, the better.
But, yes, expect much longer wait times to clear Customs. So many officers transferred down to the Southern Border to deliver room service, mop floors, scrub toilets, do laundry, and babysit our new arrivals.
From what the links in that article say, there’s 2 to 3 hour waits to clear Customs at SFO. I checked with some airline worker friends who work down in the DTW Customs station. They said waits are up a little but not too bad. I imagine the coastal big airports, plus ATL and ORD, have to be feeling it right now. And with the 4th of July travel holiday starting tomorrow... yow!
