Cons: "This was a 2 hour flight, some entertainment would be nice..."
Pros: "That I arrived safe."
Cons: "My seat didnt recline my back was in a lot of pain so was my neck. After getting to L.A at 9:52 a.m didn’t get out of the plane till 11:05 then the baggage claim was noted on carousel 2 when in fact it was carousel 3 when I asked a worker she said “I dont know ma’am” waved me off and kept walking. Terrible."
Pros: "The crew was friendly and we arrived earlier than expected"
Cons: "Seats are too tight and too expensive to upgrade."
Pros: "Flight crew was excellent. We had the emergency exit row so leg room was awesome! Kind bar and soda we good."
Cons: "Flight delay due to the older aircraft and lack of a pilot that knew how to fly it. Bathroom needed some tending to"
Pros: "The plane was an older model but staff allowed main cabin to use 1sr class bathroom."
Cons: "The choices of free snacks were limited. They should also give more than 1 package of peanut."
Pros: "It was very quick! Great service."
Cons: "We need more food options and a little bit more legroom."
Cons: "Delayed three hours with no communication or compensation. Poor customer service"
Cons: "First flight delayed 45 min, then cancelled. 2nd flight 3 hrs later."

Pros: "Great crew, efficient boarding, on time flight."
Cons: "The seats remain too small and the chairback gave my shoulders cramps."

Instead I had to spend the night by the airport in Hartford or risk missing my connection and being stranded in Chicago."
Pros: "Crew was phenomenal!!!! So attentive and professional. Great customer service"
Cons: "flight was over two hours late because of a late incoming plane. That may be for good reason, but we weren't told until less than one hour before takeoff.

One of the agents that worked for United Airlines put her hands on my friend that I was traveling with and the police got involved. It was an horrible experience and no one was trying to accommodate us for our troubles what's so ever. I will NEVER fly United again. A waste of time and money."

Cons: "The Flight attendant was rude and mean , the plane was small and old .. But most of all he flight attendant ruined the flight for everyone.

I approached the Spirit counter because I was having trouble with my app. When I asked for assistance the girl at the desk only said and repeated "boarding passes must be printed at the kiosk" as if she didnt want to be bothered or that's all she knew how to say."
