I travel on aircraft for a living. It takes a lot to phase me and I'm fairly laid back BUT it's to the point where traveling through TSA at all terminals at EWR is so bad that I have told my company that I need at least 2 hours to get thru security, and since my travel is all last minute/day of, I will be using JFK. I think United upper management needs to get involved. It is not TSA worker's fault as I assume they are following guidelines but can anyone tell my WHY when an item is flagged by the X-ray machine, they immediately run it through a second time? This jams up the lines terribly and PreCheck is just as long. Also, twice this week, a small box got caught in the machines, having to shut down the lane and get a very long pool stick to force the small box through, both times destroying the box. One of which was a part for a rocket that was going to space and could not be checked. What should have been a 10 minute precheck security experience took 90 minutes, many people missed their flights. To me EWR is the worst in the WORLD and I travel all over the world on multiple airlines through every airport in the world. Since United has no presence at JFK, and I just can't do EWR anymore, and I can't be alone. They need to reevaluate operations there and United needs to get involved IMO
