HNL -- Wednesday afternoon. (Connected via an interisland flight so can't speak to UA security/check-in experiences). TSA was doing random secondary screenings of carry-ons
ORD -- ~ 5 a.m. Thursday morning. After arriving from HNL, I wanted to exit the terminal for a little while. Main UA security lines looked horrendous. Walked over to Terminal 2. Security line there (there was an elite line, but it was longer than the regular ones) about 10 minutes.
