There were 4 parts to this flight total. The first leg of flight from odd to Newark new jersey was less than appealing. Flight attendants were visably cranky and non professional. The Newark airport is huge and horrible signage. Final leg to Dominican Republic was fine although the planes seats are high and uncomfortable. The journey home was just that. There was a woman almost completely blind and had her service animal. The lady fell asleep and the dog laid in aisle to eat h over but steward was angry about this and said something rude later she was trying to find her bag and was taking to long and same employee literally assumed she can see as he states it's right here, how was she to see it. I then took over and asked the man sitting in aisle seat to help her. Never ever united. Oh yes and the back bathroom literally smelled the cabin up.
