Anyone have this happen? Listed on a flight. Check in 35 min prior...notice a lot of non revs cleared already. That's weird, if we can still check in. Bring it up to the agent (ATLANTA) that people junior to me have seats. I asked if she cleared people early. Assured me she cleared them when she was supposed to and I was not getting on. Isn't there a reason CHECK IN closes 30 prior. Tried to look in the non rev guide. It says they may start seating non revs 30 prior. Aka after everyone's checked in. Another guy too with a 1980s seniority number was flipping out. Not right!!!
