Pros: My father passed away earlier that day and I needed a ticket quickly to fly home. At the airport I was a mess and the airline counter attendant was so amazing helping me ( I had never flown United and had no idea about their luggage policies ect..). She quickly pulled me aside.. helped me with checking in and did her best to fine me another seat thatvwas better than the one I had already chosen.Also, she gave me a hug and her condolences. Flying with an airline that has heart helped me so much during one of the most difficult times of my life. I will absolutely fly with them again.
Cons: No complaints ... but I paid for a movie to take my mind off of my father's passing during the flight and there was a short in my monitor for our whole row. It kept cutting in and out and "searching for signal", I only was able to see 1/4 of the movie I paid for with all the interruptions in signal.

Pros: Crew was courteous and helpful. Boarding was good. Planes were on time.
Cons: Planes rented and old. Pilots not as familiar with plane; interior deteriorating; seats too narrow; three men in a row had too broad shoulders to fit (could be easily fixed); under seat space dividers offset so not clear feet nor luggage space; whole plane smelled terrible— tone down fragrance
