Cons: "A baby on board was screaming and crying the entire flight"

Cons: "Do not like the high baggage fees!"
Pros: "We were very efficiently boarded, however there was a mechanical problem. The flight attendants helped every one know where their connecting gates were, as we have exactly 9 minutes to make that connection."
Cons: "We were very efficiently boarded, however there was a mechanical problem. The flight attendants helped every one know where their connecting gates were, as we have exactly 9 minutes to make that connection. We would like to give a shout out to the baggage team that were able to transfer our bags in such a short amount of time. And also to the San Jose flight that we did for four of us."
Pros: "Everything from hospitality to the ease of the flight. Captain communicated to put all at ease during this time in which this pandemic has gotten many fearful of flying. Great landing as well."
Cons: "Everything was great!"
Pros: "The seats are not fabulous the crew was"
Cons: "They did a good job keeping us informed When we got really delayed"

Cons: "Get our bags to us in the morning"
Pros: "On a quick 40 minute flight they still managed riu server coffee, water and snacks."
Pros: "Availability of WiFi, a charging port and media options puts Delta a step (or two) ahead of their competitors. The professionalism of the crew, as well as the complimentary food/beverage options are also excellent."
Cons: "Not the airlines fault, but my 6’4” frame doesn’t fit very well in a middle main cabin seat."
Pros: "Crew was gracious, kind, and accommodating; plenty of leg room and comfortable seat on the A321; liked the “My Flight” option on the screen"
Cons: "Real time video feed from cameras in the nose and underbelly of the plane in flight"
Pros: "I wanted to fly to Minneapolis. After the rain, water dripped from the ceiling."
Cons: "Pilot and flight attendants should better inform us. They should speak into the microphone more slowly and more comprehensibly so that foreigners can understand them."
Our seats were better than i had anticipated. They provided nice pillows and blankets as well as a kit with ear plugs, sleep mask and headphones which made the long haul flight better. Their food selection and service was good. I appreciated that they came through the cabin with water a few times. We were ahead of schedule which was nice!
We had a very attentive and bubbly flight attendant in our cabin. She made the flight more enjoyable. There were some issues fueling up so we ended up sitting in to plane too long, but that's no fault of American. These things happen.
Pros: "Crew was amazing, seats were comfortable. Only negative is out of your control - bad weather in DFW held up departure 5-6 hours. Much of that was on the plane, but crew kept us notified. We had to return to the gate and wait another couple of hours. Awful trip, but not your fault. What I was surprised by was no comp hotel, and the discounts were not rally good discounts."
Cons: "Most of my issues were ATC problems, not AA. The AA personnel kept us informed, etc. The one thing you can control is hotels if delayed to the point of missing all connection until the next afternoon. I understand not compi9ng BUT, when google maps shows better rates at local hotels than your "discount" program, that's sad."
Pros: "Good seat. Good films."
Cons: "A broader range of free snack types would be nice."
Pros: "Movie selection and internet quality was Ok"
Cons: "The attendant made me check in my only carry on bag despite there was plenty of space on the plane for it. My bag was subsequently lost in the airport as it was moved to a different carousel without any notice. There was no food offered."
Cons: "Delayed 1.5 hours each way for maintenance, did not allow us to switch seats to sit together previously at flight and the flight was very empty. Very uncomfortable seats. Will not fly AA again"
Pros: "We flew economy, so it was what it was. Not really comfortable."
Cons: "No free inflight entertainment. Did serve a beverage and a small snack. Crew and staff were friendly."
Pros: "The seats were comfortable"
Cons: "Waiting to board took almost 2 hours ! We were delayed so many times and sat on the plane for an hour after boarding. I was supposed to land at 6:55 and didn’t land til 9:30 and I was late for work due to poor planning. The pilot even admitted in the announcement that there was a crew problem and maintence problem. I was not happy"
Pros: "Our attendant was simply the best I have ever had the pleasure of flying with."
Cons: "Everything was perfect."
Cons: "Only negative is that the American Eagle flights must take a shuttle from the remote terminal."
Cons: "Super small and crowded flight, no safe distance whatsoever. A particular older flight attendant was cranky."
Pros: "There was nothing I liked. The plane was an hour late and nearly missed my connection."
Pros: "Business class amenities"
Cons: "Luggage drop off taking over 45 minutes (for Business Class) was not acceptable."
Cons: "My son was flying on United from Colorado Springs to Denver, then on to Seattle for Thanksgiving. He rushed through as quickly as he could, but the door to the place was closing and it left 10 minutes early. United recorded him as a 'No Show', and there policy now is to cancel the entire ticket is you miss any segment of a round trip ticket. Thus, his entire $900 was forfeited, he couldn't even pay a change fee to catch a later flight. I hate American, and now I hate United just as much. These airlines shills have been allowed to go out of business when they last filled for bankruptcy. We fly in quite a few international airlines, and outside of Alaska, Jet Blue and Delta, maybe Southwest, US carriers are absolutely bottom of the barrel and it's clear that their employees don't care whatsoever. Will never book again in United or American. I'll try Amtrak before either of those carriers."
Pros: "Seat was nice"
Cons: "Was not asked for my ID on check in, Cold on plane, was not offered snacks, steward was chomping on his gum annoying...no in flight food offered, speaker system was loud and hard to hear"
Pros: "A typical uncomfortable flight from Grand Junction to Denver. The crew was great."
Cons: "More leg room, seat very uncomfortable."
Pros: "Crew was accommodating"
Cons: "They has us deplane twice. Flight was delayed 2 hours. Need to upgrade plane equipment"
Pros: "Plane was delayed then we were switched to later flight."
Cons: "Send another plane to get the three flights that were bumped."
Pros: "The crew was great and the landing into Denver was very smooth."
Pros: "Crew from the second plane we changed was great!"
Cons: "The organization skills. After and emergency landing all passangers were left to wait for hours STANDING in line without any official annoucement. After midnight. No one told us how long is going to be the wait time, or more info about the new plane. Disorganized."
Pros: "Everything!!! Super impressed!"
Cons: "That I had to leave the amazing experience and go on vacation. :("
Cons: "Flight was cancelled without explanation. Found out at the airport instead of text, email, or call beforehand."
Pros: "You are definitely not inexpensive. I will do everything in my power to not use your service again. Your luggage policy is abominable. No thank you!!!!"
Pros: "Michael Castillo helped me with the luggage at the DEN Airport. Really nice guy! He was very kind to me made me feel like a VIP. He has great customer service skills especially for pregnant women. Also a flight stewardess lend me her sweater during the flight. It was very kind of her and she was very understanding of my pregnant needs."
Pros: "I got to sleep and I got the window seat."
Pros: "favorite flight schedule from Den to FLL or visa versa...Thanks"
Cons: "Unexplained delays. Then finally someone says the pilots haven't arrived. They still decided to board us, but apparently they couldn't turn on the air until the pilots arrive, so we cook in there, not knowing how long this will go on. Finally, the pilots arrived. Air turns on, but still we wait. And wait and wait, all the while Spirit sends me a total of FOURTEEN delayed takeoff and arrival emails. As if I couldn't already get the gist sitting on the plane waiting waiting waiting. Finally, we get rolling, but never is there any acknowledgment that we've been waiting or that they're sorry for the continued delays or something nice yadayadayada. Last Spirit flight I'll take."
Pros: "Fast easy boarding."
Cons: "Crew would not let us move to open seats that would give more comfort."
Pros: "It was not bad but it could have been a lot better"
Pros: "You get what you pay for. Departed on time and arrived early"
Cons: "The beverages (soda) were overpriced."
