I travel for work and am literally in terminal c writing this comment. I’m on dozens of flights a year and i park in a more expensive lot that’s close by (work pays) and have TSA Pre… my point is your results may vary without some of the conveniences I have. That being said Newark is no problem. For a busy airport I’d say it runs pretty well. The best thing about Newark is I can get a direct flight pretty much anywhere and coming home there are often multiple flight options so I often am able to get on a earlier flight standby. Looking forward to the new terminal A. Food options are ok but not great. Terminal B I think has the best and the terminal A that’s open now is the worst fit everything but it’s getting replaced in a few weeks I understand
