The flight was on time and boardi g was very organized and timely. Snacks are awful and having one little glass of juice was terrible. Fortunately, I had my water to keep me hydrated.

Had to go through TSA again, already purchased bottle drink. TSA would not let through, United changed gates last minute. This experience bad for everyone. Staff rude, not our fault. Staff from Chicago to Wichita excellent!
