Scores according to KAYAK customer reviews
American AirlinesOverall score based on 46349 reviews

Pros: Boarding in Bozeman was good.
Cons: Couldn’t hear the pilot at all, which was disconcerting through a pretty turbulent flight. Unclear about beverage service; some people seemed to get drinks but no one ever asked if we wanted anything. Finally the app did not work consistently for in-flight entertainment

Cons: 2.5 hour delay no explanation

Pros: Great flight
Cons: nothing

Pros: The crew was fantastic.
Cons: Boarding was like herding cattle. Everyone blocked the stairs. A frustrating mess.

Cons: Nothing

Pros: Not much. The pilot did try to keep us updated on our 5 hour delay The airline had conflicting rules on getting off the plane while waiting at the gate the pilot said yes, the attendants said no
Cons: At least offer water while trapped on a plane

Cons: No entertainment or WiFi at all

Pros: crew was nice
Cons: very very old plane

Cons: The gentleman sitting next to me never turned his phone in to airplane mode. His phone rang several times while the flight attendant was going through the safety procedures right in front of us. This was after the announcement came that all electronic devices where to go into airplane mode. The flight attendant did not do anything and seemed to ignore the phone that kept ringing. The gentleman was even talking on the phone while the flight attendant was going through the safety procedures. Later while landing an announcement came over that we were to return to our seats, close all tray tables, and seats ts in the upright position. At this point the gentleman sitting next to me leaned his seat backwards. The flight attendant passed by the gentleman at least three times and never said anything about his seat back. Evidently this flight attendant did not care to do his job properly.

Pros: Better space between the sits and the crew were nicer than prior fly with AA
Cons: Need better food

Cons: Uncomfortable Old plane with cigarette compartments Unfriendly staff They could not Sit me and my partner together because of the “fate” which was like 700 USD each! Yet they had empty seats and the ability to fulfill the request. It’s sad the low service level, operated by American Airlines booked with British Airways.

Cons: Broken seat headrest No in-flight entertainment except small screen rows away Reading lights didn’t work properly Flight attendant call signal beeped for first 2+ hours and no one could fix

Pros: 30 year old plane! Needs to retire this aircraft and move into the 21st century!
Cons: No outlets no individual monitors

Pros: That it actually happen. Poor communications from British Airways and American Airlines.

Pros: Flight was great!
Cons: It was an older plane. We liked the flight to Miami that had the super modern technology with the screens on every seat back to watch movies etc. This plane was kinda lame.

Pros: Service
Cons: Inside the airplane was freezing the whole trip

Pros: See above
Cons: See above

Pros: We arrived safely and so did our luggage.
Cons: PHL-Lisbon plane left 3 hours late due to CATERING problem. Seats were uncomfortable and food was awful. Lights and entertainment controls at my seat didn’t work.

Pros: economy plus was worth the money
Cons: Flight attendants horrible refused to serve drinks or snacks due to "turbulence" But there was no turbulence. Then when passengers complained they served water only and splashed it into cups on the trays instead of pouring it into cups and handing the cups to the passengers. Nasty people.

Cons: Left 2 hours late from Bogota

Cons: Canceled flight. Moved us to another flight IN ANOTHER CITY. Changed our second reschedule flight gate from one end of the airport to the other. NONE of the walkways worked. Total unorganized mess - this airline is run like idiots are running it! Very challenging as I have CHF.

Pros: Smooth flight with great service.

Pros: Everything about the flight
Cons: Nothing

Pros: Crew did their best!
Cons: Our flight was delayed over 3 hours. Other Advantage members have already received bonus miles for their inconvenience. I am also an Advantage member and have not received bonus points and am unable to get ahold of anyone.

Cons: Nickel and diming people for every little thing. I didn't mean to select a paid seat upon making my reservation on-line, and I couldn't get it to come off. Had to pay anyway.

Cons: old plane with worn out seats.

Pros: Very clean. Staff was very friendly.
Cons: Paid extra for six inches of leg room but the seats recline 2 inches. Not comfortable. TV touch screen did not work.

Cons: The flight leg PHL-LIS was the most unconfortable transatlantic trip I ever experienced. The plane was small, tight and no head support made this the worst transatlantic flight of my life, easily comparable to any low cost airline.

Pros: New entertainment system

Pros: Getting out of the plane! and the landing was very good.
Cons: Bad service no entertainment besides a one very childish movie. My tray stayed with me the whole flight, I had almost to beg to take it and never s flight attendant seem happy, pleasant or even profissional. The landing by the pilots was amazing.

Pros: Not much.
Cons: There are NO ENTERTAINMENT, and I had two flights that were more than 5 hours each. It was not operated by British, it was actually American Airlines.

Cons: The leg room for seats were horrible especially anyone passed 5 ft 7in.

Cons: Missed first round of golf. Have no clubs or clothes. So far this sucks.

Pros: Crew and promptness
Cons: No entertainment for each seat. No cellphone charger.

Pros: The flight had a delay of 4 hours in Philadelphia. I missed the appointment in Lisbon for which I was flying in the first place. Furthermore, I had purchased the ticket with the intent of flying with British Airways and found myself in a charter from American Airlines. I wish to be compensated for this mistake. Thank you

Pros: Boarding was fast and easy gate agents were awesome.
Cons: Older plane. Very uncomfortable

Cons: My grandparents were supposed to have escorts and assistants with their baggage, as they don't speak English and are elderly. In addition, one of their suitcases was lost and the other was rifled through. The overall service was very discouraging.

Cons: tiny plane with uncomfortable, old seats. no entertainment options on a 3 hour flight. No food options for purchase.

Pros: Everything went smooth. Staff were professional and friendly
Cons: Nothing.

Pros: Flights were on-time, planes were clean/newer, snacks were good.
Cons: Their boarding/de-boarding process was quite inefficient - they have boarding zones, but then you just go to a shuttle and it's a free for all at the plane.

Cons: We took off with low fuel diverted to DFW then on to lax with no water on board Completely unsat So much for a non-stop flight

Pros: Punctual!
Cons: no entertainment! Nothing. On the flight from Mex City to LAX the bathroom facilities were so limited that some Economy class passengers had to try to use the business class or first class facilities' An FA then came on the intercom and said Economy class must only use their own facilities and this is according to an FAA regulation. THat is a straight out lie. If you eliminate bathrooms from Economy class to squeeze in more seats this problem will persist. American Airlines should be ashamed of itself.

Cons: Maintenance delay caused me a 4 hour delay getting home on a work night. Going to be a long day tomorrow. Switched connector to United.

Pros: I booked the flight specifically because it was advertised and booked on British Airways, which is considered a nice international airline to fly. The flight was swaped to American Airlines, and I was put on an international flight that was archaic, I would have been better off flying a prop plane from the 1970's.
Cons: I booked the flight specifically because it was advertised and booked on British Airways, which is considered a nice international airline to fly. The flight was swaped to American Airlines, and I was put on an international flight that was archaic, I would have been better off flying a prop plane from the 1970's.

Pros: Food, Service, overall feeling of flight and crew
Cons: Leg room

Pros: The price is competitive. On boarding was ontime. Though the flight was redirected to Omaha due to bad weather in Kansas City, it was only an hour late than the scheduled arrival to Kansas City.
Cons: The WiFi was not as expected. In flight entertainment is null. Snack would have been better.

Pros: The flight was smooth and the coastline views were amazing.
Cons: No in-flight entertainment. Poor quality sandwiches.

Cons: flghit Porto/Lisbon 1 hour delay

Pros: Vegetarian pesto pasta was good, but all other food was not good and way too sweet and sugary.
Cons: Flight was delayed several hours, entertainment system did not have many choices and stopped working early in the flight.

Cons: The temperature on the flight was super warm. I was uncomfortable. I was told that with Layover I would receive my check in bag for Hotel stay. the attendant took a discription of my luggage for other united employees to tell me it would take 3 hours to retrieve my luggage. They didn’t even try to look for it or help me. Then what’s the point of taking my discription down? Now I have to stay at a hotel with nothing on me. So ridiculous and rude.

Cons: They boarded us in spite of the fact that the flight had been delayed 40 minutes. We were all getting alerts on our phones but were told to disregard it and board anyway. We then had to sit on the runway for 40+ minutes until we could take off. Since we were traveling with two small children, it would have been preferable to spend those extra 40 minutes in the terminal rather than on the plane.

Cons: Very crowded plane.

Pros: Crew was efficient and helpful. Captain kept us posted along the way. They also keep air flowing when we were delayed to take off so everyone is comfortable inside the crowded cabin.
Cons: Crew should try to wake me up for meals. Luckily my fellow passengers did. Otherwise I would have missed all my meals.

Pros: Pleasant, uneventful flights.
Cons: No complaints.

Pros: Emergency exit
Cons: Extra blankets as emergency exit is terribly cold Boarding

Cons: arrived 24 hours late. had to stay overnight in Newark. And United lost our luggage. The worst trip I have ever had.

Pros: Good flight, decent crew. Food was okay.
Cons: My entertainment set didn't work because the headphone jack was broken so that was a major bummer.

Pros: Crew was great. Let me sleep and was pleasant and professional.
Cons: food

Pros: Fast boarding and helpful crew.
Cons: Food was cold and soggy.

Pros: Not the flights problem that I have sciatic issues and get very unconfortable, not going to lie I was more uncomfortable than I thought I’d be. Bathrooms were clean and staff was wonderful! Besides the long flight and my own back issues, great flight.
Cons: If I upgraded to first class!

Pros: The flight attendant was very sweet and helpful.
Cons: Every.single.time I take this flight we sit and wait for upwards of 30 minutes for someone to be available to park/unload the plane. The wait is so consistent it’s ridiculous.

Pros: Hearing progress and warnings of turbulence ahead, everything else great - flight attendants especially.

Pros: The food was very good. The crew was very pleasant and accommodating. A bit late leaving but time was made up in flight. All in all a pleasant trip.
Cons: Some of the entertainment screens were inoperative. The occupied light for the forward restroom (in business class) was not working so you never knew if it was free or not.

Pros: Great service, quick and easy!

Cons: the stewardess and steward bumped seated me continually when I complained she told me it was tight inexcusable

Pros: On time departure and arrival and a friendly crew helped keep this flight smooth despite some turbulence. The fact that there have been electrical outlets on this route for so long is a testimony to the Continental heritage.
Cons: The seats in economy are just so tight that sleep on this short overnight flight was almost impossible. The lack of more recline (as in the recarro sears used on the LH/LX products) and short pitch make it hard to either work or sleep. The small plane size makes this sardine feeling worse and slows service to the rear of be craft.

Pros: No problems to deal with
Cons: Nothing

Cons: It took 35+ mins for bags to be unloaded in claim area. And I was 1st class!

Pros: Pretty smooth despite high winds and on time.

Cons: Plane as dirty and dislike direct tv

Pros: Upgraded Business Economy was much nicer than regular Economy. The flight got in to Tampa early.
Cons: Bathroom not maintained during flight. Vomiting child seated behind us (which I know was not the airlines fault, it was gross though).

Cons: We waited an hour and a half for de-icing in Bozeman and I nearly missed a connecting flight in Denver

Pros: Informative Gate Attendant Nice flight attendant
Cons: I couldn't take my computer bag on board and had to empty it because of the small space overhead. Bozeman airport was very nice. Easy to maneuver in the airport.

Pros: We got to Lisbon
Cons: The entertainment system in 36E didn't work. The sound in 36D what a lot of noise (it made it unusable).

Cons: Way overcharge for 3rd bag -$150 for single relatively small bag!

Cons: Seats have no give to recline, also the bare flights are awful cos you think you're getting a cheap flight bit then the added fees tack on, making the price similar to other slightly more pricier options. The crew was fine, no complaints.

Cons: Getting bags checked was a nightmare in Bozeman with United. Way understaffed behind the counter. This is a typical problem in Bozeman at Peaks.

Pros: The check in with united was rather disappointing. The staff working with united were not clear with instructions and rather rude. Checking in can be a rather stressful process when there are long lines and tons of people.... this person was just short, unclear and rude.
Cons: Please see above

Pros: Magazine was worth reading
Cons: Boarding process is broken. They start boarding on time, 50 minutes before the flight, but the group system they use doesn't get people on efficiently. Both legs of the flight took over an hour before the plane was remotely ready to move.

Pros: The seating seemed a bit more spacious~very much appreciated!
Cons: Nothing

Pros: 4
Cons: 4 hours late, bad food, stressed staff.

Pros: On time. Comfortable

Pros: Good solid trip. No issues and went smooth. Your team Was good both ways.

Pros: I like being able to use the United App,
Cons: I don't like having to pay for all entertainment in the headrest tvs. The app is much more convenient.

Pros: Warm friendly competent staff.

Pros: Employees were very nice
Cons: Seating very cramped I'm six foot one maybe you guys should look at JetBlue

Pros: smooth check in, effortless boarding
Cons: 1/3 of a soda can for a drink? Just give the clients a can for heaven's sake! too short a flight for much but the snacks are pretty tiny

Cons: IT system outtage, grounded all domestic flights

Cons: Hard to sleep, turbulence

Pros: There was plenty of room because the flight was less than half full. There was a very friendly and helpful female flight attendant with an Asian ethnic background.
Cons: It was impossible to check in online because I have a U.S. Green Card. Something should be done to fix this. It shouldn't be too difficult. There was a gray-haired male flight attendant who was extremely negative and unfriendly. Perhaps (I hope) he was really a security guard. But if he is going to serve people, he has to understand the concept of service.

Pros: On time

Cons: Luggage lost or left in Chicago with meds including insulin, had to stay in motel in Portland, ME to wait for morning flight. Hope luggage is on that flight. He needed his meds and only wanted to help when they said there was too much baggage. Mr. Perrin had only one carrying with everything in it. The flight itself was fine and he had good aisle seats and wheelchair at all points, but the lost luggage with the important meds caused a problem. We hope United found it.

Cons: Crew members were not helpful.

Cons: Flight left 13 hours behind schedule. No hotel room provided.

Pros: Held flight from Chicago to Harrisburg so we could make connection. Arrived MDT only 30 minutes later than original schedule.

Pros: The crew was the most polite, calm and reassuring crew I've ever come across. When faced with the mounting frustrations of a cabin full of delayed passengers, these guys were smooth as silk. Bravo!
Cons: Being grounded due to weather is unfortunate, but the team did so well in managing expectations, it's hard to be mad.

Pros: Crew was great.
Cons: Unfortantely their was a mechanical problem that delayed the flight. I understand that failures occur, but only having one mechanic available to work this problem is not good. What happend to the two person concept when working on critical aircraft systems? Pretty hard landing at Chicago.

Cons: Cancelled and rebooked on a different airline with a long layover.

Pros: New seats (more room & comfort) & movies
