If you don't like how Newark is run don't fly you will get the same customer service at any airport
Never fly through this airport if you can help it. Long security lines, terrible customer service reps, and delays on every other flight.
Don't ask to be moved to an earlier flight, it will cost you $75. And the gate agents aren't friendly or helpful.
If you book a very early flight & arrive more than an hour before boarding time, there's NO WAIT through security!
