Cons: "They are advertising free movies and is not true, because once you're settled to watch the movie there is no headphones and If you want one they sell it, is not free."

Pros: "Short flight. Free movie was good."
Cons: "Flight attendant Christina (New York crew) did not like that I changed my mind about voluntarily checking my suitcase as there was plenty of room in the overhead compartment when I boarded. She said that the only reason I found room was because, by volunteering to check my bag, I was allowed early boarding. I corrected her by telling her that, no, I boarded early because I paid US$45 for an Extra Space seat. She made a face gesture and rolled her eyes. Very childish and unprofessional. She also seemed to have trouble reading the instructions clearly."

Pros: "Nothing. I didn’t get to fly and service are check in area was a disaster."

Cons: "crew very unfriemdly"

Cons: "Nothing. All was great."

Pros: "The crew seemed capable and came around a couple times with water. We arrived safe and sound as one would hope for, if an hour or so later than scheduled. Seats seemed roomier than most standard economy/coach (probably due to it being an older model). Though I didn’t partake they seemed to offer more complimentary snack options than other airlines."
Cons: "The airplane cabin had a strong urine odor that endured throughout the red-eye flight, the air temperature had to have been at least 75 degrees, probably 80 which was a bit stifling. No usb/power at the seat which would be preferable/should be standard by now for a coast-to-coast flight. Seat didn’t recline which isn’t the end of the world but a bit of a bummer. My headphones didn’t work with the little screen at my seat but it’s ok because based on my neighbor’s screen it was just a rotating lineup of Jet Blue commercials/fake tv shows that I can easily pass on."

Cons: "When I arrived to check in at 5:48am for my 6:20am flight, I was treated very poorly. The lady at the counter asked me what time my flight was and I said 6:20 and right off the bat she was extremely rude and said that I missed the flight. I panicked internally and asked her how that was possible?! She said the cutoff was at 5:45am and I missed it. I asked if there were other flights available today or tomorrow and she said there was nothing she could do and that I had to call the booking company to see if they could book me. I wanted to cry because my friend had just dropped me off and I called to see if she was close enough to turn back. Luckily she hadn’t left yet. I called the booking company and they were able to book me a trip for the following day but they charged me an additional $100. I wish they had disclosed that we need to be there 45 minutes to an hour early otherwise you miss your flight. And it’s ridiculous that I had to pay an extra $100... financially it was stressful due to the covid 19 situation. I was extremely disappointed in how the lady at the check in counter at American Airlines treated me. She www extremely rude and I have never been spoken to in a way that made me feel attacked."

There weren't that many people in the lines, so I was wondering why. His partner at the other podium watched him quizzically, as did I, as he paced left and right, looking at nothing then sat back down again and stared at nothing. All the while the line for screening grew smaller and smaller. The other agent asked him, "what are you doing?" He responded by saying, "You said you were getting THEM all." I didn't understand, but clearly there was some subtext that I was not privy to. She shook her head and said, come up here sweetie. Then she managed to do what he obviously couldn't do: his job. Then my girlfriend and I proceeded to be profiled and had our bags searched. If I didn't have to be in OKC I would avoid that airport like the plague. Unprofessional."
