| One of the worst airports I have transited through. In the past, travelled through here en route to Florida. It seemed ok at the time although just before I boarded my connection I realised my wallet had been stolen. The security staff I contacted, and lost and found personnel were extremely unhelpful. It left a bad impression. I was reluctant to book a flight passing through Newark again, but it has been several years so I thought it may have improved - it is worse. This time around, the customer service aspect has not improved one bit. The airport has three terminals. If you are arriving from outside the US (even if you're not staying), you'll need to clear customs and go through security etc. all again. Also be aware that because there is no "within airport" transit area, you need appropriate ESTA to clear customs. There is extremely poor signage for transit passengers. To go between terminals, you hop on the AirTrain which only takes a few minutes. I had plenty of time to kill so explored each of the terminals (pre-security). I would suggest getting your food and drink (if you have time) before checking through security. At terminal A, there is very little beyond the security check point. There are few toilets too, and the terminal is very crowded. So if you can put off checking through to this terminal till you absolutely need to, I would. Terminal C is a lot bigger, and more choices for seating, food and drink but it is also a lot more expensive, even the fast food joints. The cheapest burger place charges about $8 for a burger, another 4-5 bucks for fries, and there was one poor soul making the food for everyone so long waits. I overheard a customer saying "sorry, I know you're busy, but I've been waiting 45 minutes for a chocolate milkshake". Both Terminal A and C security check staff were rude, and would not answer people's questions. At terminal C in particular, there are confusing TSA lines ups. Nobody knows where to go, there is no signage. None of the staff will answer a question, just point you towards another area or queue. There is really nowhere to get food/drink at terminal C until you pass security other than a dunkin donuts. If you have time to spare, go along to Terminal B or A, there are a few other choices like Manchu Wok, Subway, Wendy's etc. Given the airport is so busy, there seem to be routine flight delays. Both my flights out of Newark were delayed. If you have a tight schedule, factor in a couple hours just in case. Also pay attention to your gate. The gate for my return flight changed three times within an hour and there was no announcement in the lounge. It just happened that people were looking at their airline App which updated them. If you have a choice, I would not fly through Newark if I could transit through somewhere else. It's a shame as I like flying with the main carrier using Newark (can't name in this post) but the aggro of going through this place again puts me off entirely.
