Plane smelled a little funny. Flight was 30 minutes shorter than expected, but gate was occupied when we arrived. Staff was great.

Cons: "Terrible logistics. Stuck on tarmac because they couldn’t clear the previous plane out of the gate. Fellow passengers missed their connecting flights."
Cons: "Canceled flight caused me to remain in a hotel for another day. Confusing check in. No one to help. Machines broken. Unable to disembark from the plane. Bad logistics all the way around."
Cons: "Same old tiny uncomfortable commuter jet."
Pros: "Flight on time"
Pros: "Timelness"
Cons: "More leg room"
Cons: "When the delayed flight landed, the crew should help expedite those connecting to other flights. They should announce our connecting gates so that we don’t have to look it up."
Pros: "Nothing"
Cons: "Handicap issues. We were exiting on the tarmac in Charlotte- all crew left us on the plane waiting for assistance to get off. Finally when someone showed they would not come up the ramo to get my Mom. I backed her down myself while 5 bewildered airport workers looked confused."
Cons: "2 hour delays on both flights of a round trip"
Cons: "4 hour plane availability delay - of course planned on weather but not planning"
Pros: "You got us there safely."
Cons: "Not sure who is at fault for running out of de-ice solution, but keeping us sitting on the tarmac without air ventilation for almost 3 hours... with only an apology and a last minute glass of water? that was terrible customer service."
Pros: "Flight left St. Louis on time,"
Cons: "My connecting flight was cancelled while I was in the air. Customer service was SWAMPED with cancellations with only a handful of staff to help. My plane was a mechanical cancellation so I received a food and hotel voucher. Trying to get another flight from LaGuardia to YYZ was horrible."
Pros: "Flight did not take place because of cancelled return flight. the whole itinerary was cancelled."
Cons: "because of cancelled flight I had to schedule a new itinerary directly through American Airlines. The cost increased from $947.50 to $1,873 plus airport parking for 17 days."
Pros: "One flight attendant was very nice and petsonable."
Cons: "Already checked in and then flight canceled 10 hours before departure. Paid for preferred seating but rebooked on smaller aircraft full and had to sit in last row. Not happy and arrived 2 hours latet than original flight. Tried to explain this at gate to American employee but she told me to sit down until name was called. Probably could have had better seats earlier if she could have listened to my issue but she wouldn't listen to me. Didn't even have the chance to tell her what had happened."
Pros: "A cheap option to upgrade to 1st was offered that ended up being a net 0 cost upgrade for me so I took it. Comfortable on an old (but oh so nice) aircraft."
Cons: "Arrived 30 minutes early to the airport but then had to sit at a remote pad so that we ended up being 5 minutes late to the gate. A short transfer was made even more difficult, and a massive waste if time and fuel sitting and waiting. Figure out your gates early and better, and move around if needed. At the very least, bring up some stairs and buses to get passengers to the terminal and then tow the aircraft in when you have a gate available."
Pros: "I fflew Delta last Nov. Had meals movies dinner inks etc. American I am serv d beverages no meals and no movies. Getting ridiculous"
Pros: "Great seats in first class"
Cons: "N/a"
Pros: "We got to our destination safely, and American provided us with extra legroom seats."
Cons: "Service was curt and there was only phone-based entertainment."
Pros: "Fast"
Pros: "The crew was great"
Cons: "The seats were not comfortable and boarding was a pain. Not sure why you wouldn’t want to board from the back to front. Weather grounded us at our loading airport so we were stuck with the option of staying the flight or going in the lobby."
Pros: "The pilot was great. Avoided turbulence and arrived about 20min early. Easy to find seat and stow bag. Smooth takeoff and landing."
Cons: "Alaska airlines was who I thought I was riding with but the itinerary changed past min. Gate change and the airline itself was changed. Really confusing since I printed my boarding pass the night before."
Cons: "Was unable to get our bags for over 45min following the flight, due to the fact that there was no one working at any of the counters."
Pros: "Everything went smoothly."
Cons: "Flight connections time was not enough for mam with infant.we missed the flight should better set up that kind of big airport"
Pros: "To be fair. The flight is only 50 minutes. By th time you get a drink it's time to land. It is completely unfair to the staff to have to do that. A flight like that. Have a box with a snack and some coolers that have 5 different beverages. I wouldn't even sell booze. I person can hold out for a flight that shot to get one on the connection or in the terminal."
Cons: "It's always a cramped flight. Nothing to be done except use a bigger, more spacious plane. The good thing is it's the fastest way to get to Chicago from where I lived it would take 6hrs by car."
Pros: "Mostly friendly staff and quick flight time."
Cons: "Only half the plane got snacks and drinks. Additionally, I was forced to check my bag, which is a pretty big deal because I was connecting to an international flight and was unable to retrieve my prescriptions in all the rush to check my bag."
Pros: "I was so happy I could check in online and boarding was a breeze. I actually got to sit by the window when my original seat was in the middle. So nice of the ladies to suggest it to me."
Cons: "No complaints"
Cons: "The video monitor for my seat was broken. So, low entertainment score."
Pros: "everything was on tyime"
Pros: "On time take off"
Cons: "Two hours late due to not having adequate equipment"
Cons: "Flight was late, got a message from Kayak that it was delayed 3 hours...thank goodness I happened to check again, because then it was only delayed for 41 mins, then it gave me an update that it was only 21 mins delayed, then went back to 41! Pretty inconvenient, and it would have been nice to get a text, not just some silent pop up"
Cons: "Delayed a total of four hous!"
Cons: "good"
Pros: "Flight was on time, staff was friendly and boarding was organized."
Cons: "I'm a small person (5'-2", 105lbs) and I didn't have room to breathe in that tiny little seat."
Pros: "Smooth - trouble free - calm process"
Pros: "Arrived to the airport well ahead of time and encountered lines so long that we were not able to make our flight. Only 2 attendants working and so many people had to be rebooked we didn't get another flight for 3 days. Did I mention I was traveling with a baby?"
Pros: "On time arrival"
Cons: "Everything else"
Pros: "Nothing"
Cons: "The storage are very small, by the time i boarded everything was full. I had to hand carry bags and i had to put it in front of me which is a very small space already, on top of that i had the window sit so i had no space to move. it was very uncomfortable, and flight was delayed. We sat there for an hour before taking off but i understand its due to the weather but it was my worst plane ride not worth 300dollars. I will not ride american airline again."
Pros: "JAL is customer oriented and it's always a pleasant experience. Unfortunately, though the return trip is also JAL, the cabin crew isn't."
Cons: "Only suggestion would be to make the connection process a little easier. If the passenger doesn't speak English, the fact you need to print the international ticket in Miami, then re-enter at checkpoint might create confusion."
Pros: "The flight attendants were great and very friendly!"
Cons: "The wifi wasn't very good so I couldn't access the in flight entertainment I also had my own snacks so I didn't buy any food"
Pros: "Boarding was good, Good flight , good service , plane was small for the distance with limited space for movement ,"
Cons: "Got to charlotte with 80 minutes to connect. Sat on the tarmac for 60 waiting for a gate. Missed connection by <5 minutes. Thanks, AA!"
Pros: "Non stop"
Cons: "Airline"
Cons: "Boarding took forever, the flight was over 2 hours late which caused me to miss my connecting flight and my military orders were not honored - I still had to pay extra to take all my gear back to my duty station. Never had that issue with any other American airline."
Pros: "Crew was fine even when we had to sit on the ground for 1 1/2 hours for a repair."
Cons: "American Airlines didn't honor my choice of seats."
Cons: "No food or beverages for me. I slept comfortably on my flight"
Pros: "You provide me with the best ticket prices and to me that was the the most important part of of the trip thx"
Cons: "The airlines charging for your luggage"
Pros: "One I love free sodies and two I love free sodies with a smile. I definitely got both with this flight crew."
Cons: "Not enough sodies and I couldn't smell my own farts."
Pros: "First flight from STL to ORD was amazing. I was upgraded to 1st class...not sure why. Robert was a fantastic flight attendant."
Cons: "There was a delay on my second flight from ord to gsp bc there was some type of miscommunication/altercation with some passengers not wearing masks. I have been traveling since 11 am and it was annoying to have to wait another hour."
Cons: "The internet connection was terrible i was not able to see anything that was being offered"
Pros: "Friendly service"
Cons: "Cramped seating in basic economy, the upgrade seating wasn’t much better"

Pros: "Nothing"
Cons: "Aircraft, cabin crew"
Pros: "Quick boarding, departed on time, arrived early, good cabin communication"

Pros: "Efficient crew. It"
Cons: "It was good overall."
Pros: "the fact that the flight arrived on time without delay and the gates were easy to locate."
Cons: "How on earth did my i arrived lagos and only one out of my two bags showed up, i have to extend my stay in lagos and hoping my bag will come the next day, i have to pay $100 extra just to extend my one night hotel booking to two nights."
Cons: "Our flight was delayed. We did not make the connecting flight. They would not provide us another flight same day or money back or money for the rental that we required."
Pros: "Fast boarding."
Cons: "The flight was half empty and when I tried to move a row ahead of me (from economy to economy plus), the flight attendance rudely told me I had to move back to my seat since the economy plus seat was $70 more. However, a reasonable airline would upgrade their customers to first or economy plus to not only appease their customers but to fill some empty seats. Therefore, I had to spend the entirety of my redeye flights crammed next to someone while I was looking at an almost empty economy plus section. Also, we boarded earlier than expected but we spend an extra hour on the flight waiting to take off. I would not have minded boarding early if we had taken off early, but we took off an hour later."
Pros: "He was the epitome of the Friendly Skies. Chatted with whom wished to chat was quite near those that wanted to snooze on this early morning flight."
Pros: "Boarding and flight went smoothly and on time. Too short for food or entertainment"
Pros: "The crew on the plane was nice and helpful."

Pros: "Everything was excellent! I even got upgraded to a window seat!"
Pros: "Service was excellent"
Pros: "That I didn't have to walk to Fargo. I wasn't dragged off a plane."
Cons: "3 flights to Fargo were cancelled. I was told I would not get to Fargo until 32 hours after my original time I was suppose to land in Fargo. After spending a fair amount of time on the phone with customer service I was able to get me on a Flight to Minneapolis that did not arrive till 1:30am then had to take a rental car to drive 3.5 hours to make it to my destination. I was not compensated for any of this. My return flight from Fargo to St. Louis was also Delayed. Both from Fargo and from Chicago. I have never experienced such poor scheduling from an airline or as many delays or cancelled flights in just a few day period."
Cons: "Never on time"
Pros: "I managed not to use toilet."
Cons: "An epic storm (April 27-May 4) caused my bicycle tour across MO to flood out during our trip. Rescheduling my flight back to CA cost &230..same price as RT. Gouging people leaving a massive flood! The governor of MO declared a State of Emergency yet my trip cancellation insurance didn't cover what was clearly beyond my control. I'm left with some hard feelings."

Pros: "Flight was pleasant."
Cons: "My luggage was left behind and it was an awful experience! My medication was in my luggage and could not use it which made me suffer tremendous pain and discomfort. No one got back to me to offer compensation!"
Pros: "Both flights left on time and arrived at least 20 minutes early. My bag arrived at the baggage claim ten minutes after I arrived, and all went very well. I'm grateful."
Cons: "All was perfect"
Pros: "The service was prompt and professional. The plane on this trip was clean and in good repair. The snack was simple and tasty. It was a pleasure flying United."
Cons: "The first flight from St. Louis to Chicago was very small. While I don't have concerns about flying in a small plane, I can imagine those nervous about air travel would feel concerned with the size of the aircraft."
Pros: "The boarding process went smoothly and was on schedule."
Cons: "Overhead compartment filled up and it was hard funding space for my bag."

Cons: "Luggage compartment too small even for a rolling laptop bag"

Pros: "I like the seats and the leg space .they were very comfortable ."

Cons: "The delay. It was approximately a 2 hour delay getting to Arcata."
Pros: "Wifi on flight"
Pros: "Gate agent was great.... Have me an edit row seat. But my 90 minute flight from St Louis, led to a 40 minute wait for my bag"
Pros: "we were 10 minutes early to the gate"
Cons: "super cramped quarters, like touching legs to the next person the whole squirmy flight close... the plane was made for little people."
Pros: "Rain delayed our take off but most of the time was made up. No complaints!"
Cons: "Forced to check our carry on suitcase even though there was plenty of room above the seats."
Pros: "They got me on a flight home that night"
Cons: "I had to wait 4 hours in the St. Louis airport and 4 hours in the Dallas airport. Was a very long day!!!! I do not like to fly American Airlines and that was the only flight that was available. The plains are small and cabin pressure always hurts my ears."
Pros: "Flight was on time"
Cons: "I wish we would have known ahead of time that we needed our own personal devises to watch a movie. We would have been better prepared. We didn't" have long to download the Intied app and for some it just wouldn't load so they could watch a movie. I also wish there was a better selection of movie to watch."
Pros: "Departed close to on-time. And as a pilot myself any landing you walk away from is a good landing."

Pros: "On time. Quick boarding, very efficient."
