Been a long time since I flew out of AEP but had a similar situation except with checked bags. Despite seeming crowded and chaotic, AR check-in with baggage was very fast (probably in the seconds). Security line also seemed long but moved fast enough so we couldn't even finish the coffee we had bought and were holding. We were instructed to either carry it on or put in on a tray through the X-ray machine. All very fast and efficient. Had plenty of time to sit in the departure area.
