Airline reviews

Pros: "Aircraft was clean and comfortable. Crew was efficient and friendly. The whole experience was excellent!"
Cons: "There was lots of entertainment available but plain old music was not an option. What if I don't want to watch a movie or TV, just listen to music!"

Cons: "Seat cushions are too thin."

Cons: "Two rows up from us, I kid threw up all over the center aisle as we were pulling away from the gate. We returned to the gate to allow a cleaning crew to board and clean. However, the cleaning job was rushed and left remnants of the throw up behind which smelled the whole 2.5 hour flight. It really felt unsanitary and unsafe being that it’s unknown what caused the child to get sick. It very well could have been a stomach virus and could have infected the people in rows around the incident due to the mediocre cleaning job. I understand that it’s important to keep flights on-time, especially for connecting flights, but the safety of the passengers and their health should ALWAYS be the #1 priority."

Pros: "Comfortable seats with nice details; power ports; drinks and snacks."
Cons: "Boarding in Seattle was ridiculous. Security took a massive amount of time, and we barely arrived in time for th flight despite arriving hours early. The attendants at the gate were a bit rude and begrudgingly accommodating."

Pros: "Management as well as staff nice...First trip with Alaska and made my trip nice .. Got a good deal price too."

Cons: "Boarding was a hassle. The flight was too crowded. The food was non-existent.. Seats were uncomfortable."

Pros: "It was on time and friendly"

Cons: "Two out of three USB ports would not hold cable on my premium seat row. Would not recommend if something as simple as USB port inoperable is not handled by cabin service or maintenance. We paid additional fees for this seating and couldn’t keep device charged. Very disappointing"

Pros: "I didn't have to set next to a 500 pound cow."
Cons: "Your beer and wine is sooooooo expensive."

Pros: "The crew and captain were amazing and very apologetic!"
Cons: "I paid an extra $300 for preferred seating because I wanted the extra legroom to sleep. I'm over 6 feet so coach is very uncomfortable. My girlfriend and I got in our seats and 10 minutes later, a crew member walked back and asked us to get off the flight. We got off the flight and were met by police officer. Low and behold, the woman sitting next to us said that she believed we were intoxicated and feared for her safety. I am a police officer and my girlfriend is a nanny/preschool teacher. Not very threatening. The officer on the ground looked us over and asked us a few questions and determined we were not intoxicated and we were no threat to the other passengers. The airline asked us to get back on the flight and we would be sitting in coach because the woman adult children were now sitting in our seats. I told them to book us on another flight with the same seats that I PAID for or put us back in OUR seats on that same flight we just got kicked off of. We were escorted back onto the flight and the crew asked the woman's children to go back to their seats so we could have our seats back. They then asked us not to speak to the woman sitting next to us (which we never did to begin with!!!) and then told us we could have free food and drinks. The whole experience was insanely embarrassed and I can't believe that woman sitting next to us can get away with what she did. I am absolutely livid that they would ask us to get off the flight and then give our seats to the woman's ADULT children without vetting the situation and making the easy determination that we were NOT intoxicated. So embarrassing!!"

Pros: "The crew did their best to deal with delay."
Cons: "There was an absolutely awful job done by both Delta and Kayak of informing us if additional delays, new gate assignments, when the plane would be reboarded.

Cons: "Chairs really uncomfortable"

Pros: "One crew member was especially amazing"
Cons: "The rest of the crew were meh. This time there was no food. I pillows. Water leaking from the ceiling."

Pros: "Delta crews are very friendly and helpful. Seats are 'good' on the E175 plane - better than the cramped CRJ200 on some other short flights.

Pros: "Good"
Cons: "Seats"

Pros: "Two Delta agents a kiosk assistance were not aware of the Hurricane Irma policy of waiving baggage fees to my destination.

Another Delta agent nearby had to show them a copy of the policy before I could get my baggage fees waived."

Pros: "Smooth flight."

Pros: "The crew was nice and helpful."
Cons: "The economy plus wasn't nearly as nice as any other airlines. It gave the least amount of extra leg room and the only other amenity they gave was a toothbrush. Even United economy plus is bigger. Plus if you want to change anything you have to pay include just to try and go stand by on an earlier flight."

Pros: "Very friendly staff and the onboard meals were surprisingly good. Korean Air may quite possibly be my favorite airline."

Pros: "The food was extremely good on this flight, as was the aircraft interior."
Cons: "The TSA queues in Orlando were awful."

Pros: "Our flight was cancelled and we had to buy $447 worth of Southwest tickets to get home. Our luggage is still missing, by the way."

Pros: "Service"
Cons: "Old aircraft"

Pros: "The crew were super helpful with my toddler and 5year old as I was traveling by myself. Everyone was very friendly and allowed me to board early as well as helped me when my toddler was crying to distract her. Service was fantastic! The plane was new and I really appreciated having entertainment I didn't have to pay extra for."

Cons: "Too much to write down. Start at the counter and work yourself to the plane. I hope you get it right eventually, I’ll be flying Southwest"

Cons: "Feed me"

Cons: "My one hour layover turned into a 4 hour past 2AM arrival time."

Cons: "No screens, poor WiFi connection and an hour late for mechanical issues. Things happen but waiting on a mechanic for almost the entire time to get there and fix it in 5 minutes isn’t acceptable."

Cons: "Less crowded."

Pros: "I was in first class this time. The seat was comfortable for the flight of roughly 2-1/2 hours. We were served a continental breakfast that was filling and healthy with cereal, fresh fruit, Brie, soft crackers and yogurt. I'd rather have something simple but satisfying than something overcomplicated and possibly not that good. The crew was polite and efficient. I did have to use the lavatory at one point and I was happy that it was clean."
Cons: "The entertainment system was down, but it wasn't American - it was gogoflight or whatever it's called. I ended up listening to my Audible so it turned out alright, but on a 2+ hour flight, it could have been frustrating."

Pros: "Crew was helpful and fine."
Cons: "Don’t delay all your flights American Airlines. They are never on time."

Pros: "Yes"
Cons: "Everything was fine"

Cons: "Nothing. Everything was great."

Cons: "We had to wait for a flight attendant in Louisville going to Chicago, which made us a little late to OHare. Then we had to wait at OHare for another plane to leave. I ran from the one set of gates to the other, but I missed the boarding, even though the plane was still there. I was extremely disappo"

Pros: "Would’ve loved if the flight from Louisville to Charlotte weren’t delayed 2 hours for mechanical reasons!"
Cons: "The flight could’ve waited for us instead of leaving on time for Allentown!"

Cons: "Beverages"

Pros: "Stewards were good."
Cons: "Mechanical problems and incompetent repair people who forgot to fill out paperwork delayed our flight by 3 hours. Because of this I almost missed my RESCHEDULED next flight and my bag was gate checked to baggage claim."

Pros: "Friendly crew, excellent food options, very clean cabin."
Cons: "I had to pay for water."

Pros: "The crew was accommodating"

Pros: "I loved the attitude and helpful approach of the female flight attendant working the AA gate for the flight I took from DFW to COS last night (6/13). Truthfully, it was almost like I was back with Southwest. She was kind, calm, polite, efficient, and capable. Very rare in my experience with American Airlines yesterday. Interacting with her was refreshing."
Cons: "Getting home to Colorado Springs at 11:30 PM, taxiing for 15-20 minutes, and then waiting another 20-30 for checked luggage! Never have I waited that long during and after a Southwest flight! AA could truly learn something from their more modest counterpart. I have all but decided to resume my drives to Denver every other week rather than risk more and more time and poor experiences with AA flying in-and-out of Colorado Springs."

Cons: "Flight departure was delayed by 4.5 hours. Then when we finally landed, we had to wait nearly 2 hours on the tarmac before we taxied to the gate. American kept us in the dark about what was happening -- I might have made different plans if I had known what was going on."

Pros: "The flight was great--good food, good service, good entertainment, on time."
Cons: "They lost our luggage. Four people traveling together arrived in Phnom Penh, but our luggage didn't. It took almost 2 days to be reunited with our luggage."

Cons: "No gluten free snacks. Flight was late"

Cons: "Made us wait over 2 hours on the tarmac before take off inside the airplane."

Pros: "Great service"

Pros: "The selection of music and movies to watch was extensive and wide ranging. All the Star Wars movies as well as great Disney movies as well."
Cons: "Felt very rushed when eating. Once the food/drinks were dropped off, it seems right away the staff was ready to pick up and clean."

Pros: "The crew were friendly and did their job effectively"
Cons: "Lack of seat space Planes seemed old Minimal overhead storage room—carry on fits all other airlines overhead but struggled to get bag in compartment Also, no help from crew with this Seats recline nearly into lap of person behind"

Cons: "I was expecting this to be a flight by Japan Airlines but it turned out to be an American Airlines flight. I was expecting and wanted to experience a flight from another airline."

Pros: "Nothing. Had a family emergency"
Cons: "I had a family emergency and had to buy a ticket to Pittsburgh to get home instead of going to Portland."

Cons: "Departed late and missed connection due to an overage of fuel. The crew took an additional 45 minutes to defuel the plane of 8000 gallons. Wth?! Have to stay overnight in Chicago now."

Cons: "After being delayed without any explanation, I was told that I would not have my purchased 1st Class seat. To add to that I received no service In economy."

Pros: "Loved the individual TV & ability to charge my cell phones"
Cons: "Very tight leg room, no food to purchase, no snacks."

Cons: "I don't like the fact that American Airlines try to get me to put my small carry on bag below both ways in the cargo area it is against FAA to have batteries down there. I have 30,000.00 in cameras and they tried to get me to do this both times saying the bag will not fit. The Flight Attendant each time say that it fits JUST FINE! I'm going to try to avoid American Airlines as much as I can!"

Pros: "My flight wasn't completely full, so I had a row to myself. The pilot was excellent; takeoff and landing were very smooth."
Cons: "I had to gate check my luggage because of the small plane size. Had I had a shorter layover this could have caused an issue for me."

Pros: "Smooth flight. Flight crew was kind and curtious."

Pros: "I liked that the internet connection was free because I am a T-Mobile customer."
Cons: "Boarding the plane was a bit clumsy. I felt like everyone was tripping over each other since the front of the plane was boarding first."

Cons: "It was over 30mins late for no reason!"

Pros: "Courteous crew, easy experience smooth "get in and get out" process"
Cons: "Flight was late due to weather but that's beyond anyone's control obviously"

Pros: "For the price I got my ticket for. This was a good deal. I paid extra to upgrade to main cabin extra but well worth it."

Pros: "Flight was on time. Smooth flight."
Cons: "In flight entertainment was below expectations"

Cons: "Boarding process was bad, the kisok did not print all the boarding pass . The Flight was delayed and the Airlines was extremely poor in communicating the same."

I got there around 11:30pm and my flight wasn't till around 9:45am the next day and so when it came to that time they had cancelled my flight so I got another ticked for around 2pm and they didn't board that flight till around 4:30. My experience there was to much to handle. I was supposed to get to Colorado Friday night but didn't even get here time Saturday afternoon. Really upsetted me because I leave wednsday so I don't have enough time to be with my boyfriend. I honestly don't think I'll be flying American Airlines again"

Pros: "The crew moved quickly to get us in the air once we had a plane to get on."
Cons: "I waited in an airport for 10 hours because there wasn't a place to get on. They messed up the schedule then two different planes had problems that made them unsafe. This made me feel uneasy about flying with them at all. Overall not a good experience."

Pros: "The flight attendants were nice and the plane was on time."
Cons: "I tried to switch my flight to an earlier time. First, they charge $75 (Southwest is always free). Second, the gate agent charged me and let me board, but her boss came on the plane and pulled me off because I wasn't Executive Platinum status! The plane took off with an empty seat and I had to wait two more hours for the first flight. When I complained to AA about it, they sent me a $50 voucher. I don't plan on giving any business to AA for the rest of my life."

Cons: "When I spoke to the United person last week to confirm baggage and carry on requirements. He said I could take a carry on when I turned up to the gates I was charged another fee for my carry on bag.
