Schengen zone flight (essentially the EU). Almost always fast. Did so late March and it took 5 min waiting in line. I know it’s been bad in the past, but it’s been a while since I’ve seen it get that bad.
Heck, at the beginning of March, I had a 50 min layover from Delhi to SLC flying through AMS. I had to go through security again, and there was very little waiting.
DFW during thunderstorms doesn’t surprise me at all. That’s happened to me a couple of times, once with my daughters when my youngest was 2 (and it was just me, my wife hadn’t traveled with us). We had to wait for about 3.5 hours to finally board the flight.
