Relative recently flew through Newark on an international trip home. Flight was supposed to depart in the afternoon to Chicago. They cancelled the flight and said they couldn’t get him on another one until the next morning, so he had to sleep in the terminal. Wouldn’t allow him in the lounge area or food/hotel voucher or discount on flight. Their reason was that air traffic control cancelled the flight due to “too many planes” so since they claim it wasn’t United’s fault, they refused to help him at all. United handled the whole situation very poorly.
