Airline reviews

Pros: "The accommodation to the military service members!"
Cons: "Air fresheners should be used on the airplane."

Pros: "Delta is doing a great job keeping everything calm and clean during this pandemic!"

Cons: "Nothing all excellent"

Cons: "It was great! Nice job Delta !"

Cons: "Wouldn’t change a thing! I don’t always fly! But when I do!! I fly delta!!"

Pros: "Christina brown was amazing at gate"

Cons: "The main economy seats were far too narrow."

Cons: "It was a Great flight. I always enjoy flying Delta"

Pros: "The crew was great and the free entertainment was great"
Cons: "Bring back pillows and blankets especially on red eyes out of Anchorage"

Cons: "No meal option and my video screen volume did not work"

Pros: "Not comfortable a little but scary on the flight to Detroit. Way better coming back to Denver"

Pros: "great crew!"
Cons: "luggage. what a nightmare. I waited 30min for my luggage (after a delayed flight) only to be told by a fellow PASSENGER that some of our luggage was directed to a FRONTIER CAROUSEL. I then had to wait by that carousel till I found it. so much for "bags in 20min guaranteed""

Pros: "Entertainment"
Cons: "Boarding at JFK.Always messy"

Pros: "Inflight experience was fine. TVs didn’t work but Flight attendants are friendly on Delta, cramped seating - but not unlike other airlines."
Cons: "Regular fare seat assignment not available prior to gate . Airport concourse F - poor - limited services. Customer Service seemed uninterested and unable to provide service both on phone and at gate. I’m a frequent United flyer & today’s Delta service experience made me more loyal to UA."

Pros: "Early and middle seat was open!"
Cons: "Coffee tasted like fish. :("

Pros: "We boarded close to on time, no hassles. Allowed my husband and me (retired military) to board early, thank you."
Cons: "LAX security is awful. We never left the airport (arrived LAX from Sydney AU) yet were forced thru security again. Had to remove shoes, was scanned and "frisked" by TSA to get to Denver. To go to Australia, Denver TSA waived the removal of shoes, skipped the scan for the metal detector and no one touched me, ditto for LAX on the trip to Sydney. Where's the uniformity or standards for TSA?? Why did I have to be subjected to this garbage on the way home?? This is why I despise flying. It makes no sense to me. This ruined what was a great vacation."

Pros: "Not much. Boarding by "zone" works ok, but is no quicker than most other boarding methods."
Cons: "Boeing 767-400ER seats had no leg room for 6'+ traveller like me. The entertainment system was so old that there were no 115v outlets or USB ports. On a 7-hour flight, that is a significant problem for travellers today with multiple electronic devices. Finally, we were not told in advance that we had to go through security twice and through US Customs BEFORE leaving Dublin. So, the 6-hour layover at JFK was a complete waste of our time as we did not have to go through Customs there."

Pros: "Free drinks and snacks - great entertainment system (please read this Frontier)!"
Cons: "Boarding process was agonizingly slow and ineffective"

Pros: "Everyone who has a kid knows how challenging certain things can be in a flight and for me the combination of a night flight interrupting my baby’sschedule + a full flight it equalized disaster. My daughter could not get comfortable for the love of life and I just felt horrible and frustrated and what sucked most was the 9 year old and her obese father siting in our row that kept giving us weird looks."
Cons: "There’s NO room in planes between seats. It’s 2018 and new planes must be done ASAP to accommodate people better. I’m 5’1” and 110 lbs but adding my 25lb daughter siting in my lap before she turns 2 is absurd to expect that it will be comfortable whatsoever for us or the people breathing next to us. Please DELTA, lead by example and make sure your planes are designed with more room in between and around the seats. In my opinion, every seat should be first class."

Pros: "In a pinch they were able t"

Pros: "Everything was perfect !! Staff friendly"

Pros: "Great in every way"

Pros: "It got me home, eventually."
Cons: "Poor communication, a 6 hour delay followed by a 7 hour layover (during which we had to sleep on an airport floor because Delta couldn't offer us any hotel vouchers). Gate agents disappeared after 7pm becuase they were due to be done with their shifts when our flight was originally supposed to leave at 6 pm. It felt like we were trapped in the movie The Terminal. Oh! And our bag was misrouted, because that was just how things went those 2 days. All in all a 6 hour trip turned into 18 hours. I could have driven home in that amount of time!"

Cons: "Check in lines were crazy long"

Cons: "could not check in on line as you did not give us the confirmation of the carrier we used which was not west jet the one you booked us through. You need to fix this problem for us to use you again"

Pros: "First leg from San Diego was excellent."
Cons: "Arriving in SLC discovered out flight to Denver was CANCELLED! Had to reschedule to the next day. Not fun!"

Pros: "The entertainment unit allowed me to watch the Denver Broncos game live which helped lessen the delayed departure and uncomfortable seating."
Cons: "Uncomfortable seating....too crowded!! We had a delayed departure by 30-40 minutes because of a computer download issue. Too many folks carrying carry-ons delayed boarding. I wish folks were not encouraged to go that route but to check baggage. This time of year gets even tougher with folks carrying Christmas presents and over sized personal items. Ugh. Not fun to travel this time of year."

Pros: "App is good and convenient to use."
Cons: "The app went down just as we were getting ready to board and luckily i had a printed pass and it took some extra time to check in."

Pros: "really helpful and friendly service and nice seats."

Cons: "We left late, it was delayed then maintenance issues. Twice. Seating was very tight and uncomfortable, no movies or entertainment at all. U.S. flights are the worst. Even on short flights with aeromexico outside the U.S. you get movies and food. Zero stars for comfort, food and entertainment."

Pros: "Almonds as a snack. Pleasant crew."
Cons: "No entertainment and my table was broken. The air from the vents was also colder. Not much leg room and I have short legs."

Pros: "Everything"
Cons: "Nothing. Delta is the best airline in North America"

Cons: "I don't like that I already completed this survey several days ago and have been receiving reminders to do so. I guess you don't have a good system in place for knowing who has and has not completed your surveys. That's too bad."

Pros: "The plane, crew was clean, newer and had TV's in the backrests. Remember to bring headphones! Seats are tight, but the crew was friendly and may the flight experience positive."

Pros: "Friendliness of staff. Second flight was a newer plane - sweet!"
Cons: "For a long flight perhaps a little more in the snack department."

Pros: "Crew was all very nice"
Cons: "Flying is always uncomfortable"

Pros: "Not much to like here. The new crew was pleasant"
Cons: "Old crew was surly. Plane had much problems and finally replaced. Left 5 hrs late. Delta claims it doesn't have to compensate for a late flight - just a cancelled one so guess which this was The baggage fees are obscene and the gouging of the customer is immoral. No wonder people hate the airlines."

Cons: "Excellent service excellent pilot"

Pros: "Overall, the flight was very smooth and I thought the crew did a great job."
Cons: "I know this is a federal regulation, but I have to mention it as it is part of the boarding process. For the life of me, I can't understand why it is necessary to go through security again after re-entering the country. Understandable that I have to go through customs, but going through security again is ridiculous."

Pros: "Flights were both on time and boarded quickly. Crew was wonderful!"

Pros: "Free in flight entertainment"
Cons: "One of my bags went to Santa Fe"

Pros: "For once the food was good"
Cons: "Screaming out of control children. Parents not caring that their children were constantly running up and down the aisles. Crew unable or unwilling to intervene."

Cons: "One hour late after a stay over already 4 hours."

Pros: "Early arrival. And service"
Cons: "I was assigned very last seat and there is no reclining option."

Cons: "long wait and delayed flight"

Pros: "WiFi, good flight attendants"
Cons: "Would like to see Direct TV along with Delta Suite so can watch live TV"

Pros: "Very professional and caring."

Pros: "plane had individual movies for free with each seat!"

Cons: "I've only experienced delayed flights with Delta ... and this was no exception. It wasn't weather-related, nor a late flight delivering a plane - just no ground crew to service the plane between flights."

Pros: "yes every thing was good.."

Pros: "Everything, thank you"
Cons: "Nothing, everything was perfect, thanks."

Pros: "Crew was very friendly and helpful"
Cons: "This was the first time in 37 years that I have flown so i had a little motion sickness but that has nothing to do with your crew or airline. This experience was very good thank you"

Pros: "Left early and arrived early"
Cons: "Cabin was way too warm. Also not as much space on 737-700 as 737-800"

Cons: "We landed in Phoenix and spent over an hour on the runway, when we did finally get a gate it didn’t work. The delays caused me to miss my ground transportation."

Cons: "Flight was delayed. Otherwise fine."

Pros: "I booked Cathay pacific but they changed to China Southern without any notification."

Pros: "The service was excellent and got help with the infant, friendly staff"

Pros: "No delays flight arrived ahead of schedule"

Pros: "As always, great service and flight"
Cons: "Nothing to complain about"

Pros: "The friendliness, the options through the app with movies etc"

Cons: "Security took way to long to clear."

Pros: "Overall an easy experience. Cheap!"
Cons: "West jet has got to figure out a better way to board the plane- the "zone" model is a nightmare."

Pros: "Seat comfortable"
Cons: "WestJet app to watch movies and tv not available. Only old screens in back of seats."

Pros: "Great airport, friendly and helpful staff. Onto e departure and arrival and very little baggage wait in Vancouver"
Cons: "Nothing"

Pros: "It's a way to get from point A to point B."
Cons: "It's like taking the bus, it is what it is. Not great but it gets you there."

Pros: "Very entertaining flight crew. One attendant cracked jokes sang happy birthday announced wedding party . Never boring very friendly"

Pros: "I like everything"

Cons: "I was told they don't help you store your carry on. At 66 and 5 feet tall this seems like an impossible feat likely to create issues as it falls on my head."

Cons: "Can't rate food. None provided."

Pros: "Friendly and helpful staff."

Pros: "Good in flight entertainment and food"
Cons: "Not enough leg room"

Pros: "Good amount of leg room. The children were well behaved."

Cons: "Crew are not that friendly and not polite."

Pros: "Nice, professional crew."
Cons: "I have a dog in the plane with me. None of my flights offered to make me board first. It harder to move through the aisle by myself with my pup in her carrier and my personal effect . Some nice passengers helped me when they saw I was struggling but O feel that is the crew's job."

Cons: "It did not happen. Being transfered to air canada in Toronto was a night mare"

Pros: "THE flight got me home"
Cons: "Th check in staff made light of what seat I was assigned stating it was the best seat. 23A a bulkhead back row seat that did not recline. I was then Seated next to an individual that should have had two seats to themselves instead of most of my seat and theirs. I was literally pressed into the bulkhead by the very large person next to me. Who had another large individual next to them. WestJet used to be a great airline that Had a little more legroom. Now airlines like flair offer the same flights with more legroom wider seats and far lower costs. WestJet has lost me as a customer that used to pay a little extra if There was a WestJet flight option"

Pros: "Great seatmate. Friendly crew. That is a plus."
Cons: "Wish the seats weren't so tight and close to each other."

Pros: "Folks are nice.."

Pros: "Everything was exceptional"
Cons: "Nothing to complain about"

Cons: "the 3 hr security line up"

Pros: "Quick boarding on departure and exit at arrival."
Cons: "Delayed flight."

Pros: "The WestJet staff, from gate check in to the flight crew, were excellent."
Cons: "The fact that people with pets board first is ridiculous enough to keep me from choosing WJ as my first option. They boarded before seniors and children. What has happened to our crazy world that pets are more important than people."

Pros: "Everything"
Cons: "Nothing"

Pros: "On time, clean, friendly staff."
Cons: "Crew missed me with the drink cart."

Pros: "All Good"
Cons: "After landing in Edmonton could of been on next flight to Kelowna ended up waiting 1 1/2 for second flight to Kelown"

Pros: "Nice crew"

Cons: "Seated @ the back & disembarking at the back door. Quick, easy on a bright sunshine day."

Pros: "Crew"
Cons: "Delays"

Pros: "Overall everything"

Pros: "The staff with West Jet are extremely helpful and friendly. I wish the American carriers would take lessons from them."

Pros: "Luggage came fast. Car rental was great."
Cons: "Changed planes, changed seats after paying for advanced booking. Service was poor, cabin was hot."

Cons: "The long wait to get my baggage."

Pros: "Staff was kind as usual. Some channels didn't work so they gave us complimentary movies."

Pros: "Everthing"
Cons: "Nothing"

Pros: "Seamless boarding"

Pros: "It was quick and efficient"

Pros: "The attendants were very cordial and considerate."
Cons: "My son did not do well with the food on the trip. He became ill. The food did not smell particularly delicious."

Pros: "Too many delays."

Pros: "Flight crew was amazing. Food was good and there was plenty to make the time go by faster."

Pros: "On time arrival"
Cons: "In general I like the flight stability of 747s. However the seats were very cramped for such a long flight, and unlike more modern aircraft, the seats lean way back pinching the person behind. Entertainment system is rudimentary at best, with few choices and a minuscule screen (but I shouldn't complain, at least there was something to watch). Also, at Heathrow airport (nobody's favorite airport) we had to board buses to get to the airport and walk up stairs. Inefficient, and difficult for older passengers such as myself."

Pros: "Crew was pleasant and food service was good"
Cons: "Not a very big or good quality selection of movies and viewing screens were hard to see"

Cons: "Staff and crew were courteous and helpful. Seats were comfortable."

Pros: "Things went as planned in the beginning. The young lady who checked me in at the BA counter was very friendly and helpful. The preboarding and boarding went very smoothly as well."
Cons: "The plane boarded as usual then things went wrong. There was apparently something that went wrong with furl getting into a separate storage tank (that's scary in itself...how does that happen?) and they announced that they couldn't get the fuel tank to fill completely and the mechanics needed to get a "special tool" to complete the process. Then they needed some "tool" to drain the fuel from the mysterious storage tank. That was done and they announced that they had decided that they had plenty of fuel to make it to Denver. An hour and a half later of sitting in a sweltering hot cabin the y announced that the mechanical issues were taken care of BUT we'd have to wait another 20 minutes to take off because of the traffic waiting to leave Heathrow."

Pros: "Direct flight London to Denver. Check in and boarding very easy, friendly and efficient."
Cons: "Seats very close together, entertainment poor (and not working for first hour of flight)"

Pros: "Do the upgrade if its available!"

Cons: "long delays between segments of the flight however the business class BA lounge was excellent . Entertainment systems on the 747 aircraft are getting dated"

Pros: "Very professional and friendly employees. Someone fainted in our cabin and the crew members took very professional care and offered the passenger oxygen."
Cons: "Very packed cabin, offered us just a sandwich after the first main meal."

Pros: "Food was decent and they came back to offer us another drink."
Cons: "Plane was old and dated. No usb or outlets to charge any devices on a 10.5 hour flight. Also seating was small and cramped. I wish there was a way to automatically get an isle seat or emergency row seat if you are over 6ft tall."

Pros: "747s are good stable planes in flight"
Cons: "The greatest problem was dealing with the usual chaos and discomfort of traveling through Heathrow airport. Primitive and time-consuming transportation system between terminals- Had to ride overcrowded buses packed with so many people that your body was pressed against your neighbor. Inadequate number of restrooms and poor signage to find them. Bad selection of restaurants. Then at the terminal, boarding time listed as 10:40, but they did not even announce the boarding gate until 10:40. Then a 10 minute ride on another overcrowded bus to the plane which you had to board by a staircase (and a staircase to the door on a 747 is no small thing!) Although flight was smooth in the air, the pilot landed so "hard" I thought the landing gear must have been damaged!"

Cons: "Checked-in baggage got mishandled and haven't got any response from British airlines after 24 hrs of complain filed."

Pros: "NA"
Cons: "The transfer from T5 to T3 was chaotic. Queues to join queues to get the transfer bus. People were getting caught on a moving escalator because the crowd in front had nowhere they could go to make room. Extremely dangerous! It took longer to get from T5 to T3 than it did to get from Dublin to London. Boarding in T3 for the flight to Denver was almost as bad. Bodies everywhere, no organisation and no help. Then the aircraft itself was so old with uncomfortable seats and an almost unwatchable screen. I will never transit through LHR again."

Pros: "Air hostesses were good"
Cons: "Poor food, and very little of it is given. poorly run airline. Too many unnecessary rules that don't apply to any other airlines that they claim to be in the name of security. Will not fly again."

Pros: "On-time/early arrival, relatively communicative staff who also provided timely service. Bags delayed upon final destination."
Cons: "Seating became uncomfortable after so many hours. Boarding times long. Staff was at time over the top with their checks."

Cons: "terrible seats. unable to recline my seat. horrible experience for 8 hours..."

Pros: "I liked the fact that the customer service on board was pretty spectacular & very clean bathrooms."
Cons: "It was extremely warm throughout the flight and the seats weren’t too comfortable."

Pros: "Everything"

Pros: "plane was not full so plenty of room to move around etc"

Cons: "transfer from terminal 5 to terminal 3 - process was unclear"

Pros: "Meal from Lagos to London was good"
Cons: "I don't know why spray was used on Lagos flight to London and London flight to Denver no spray."

Pros: "I was able to sleep without being disturbed."
Cons: "My flight was delayed 4 1/2 hours"

Pros: "Competent crew. Arrived early."
Cons: "The plane was so old it had signs that read, no smoking in the lavatories. The entertainment screen was small and slow to respond. Should be in a museum."

Pros: "Checking documents on entering gate area rather than at boarding time, made for more efficient boarding"
Cons: "Delay in baggage reclaim due blockage in system"

Pros: "Flt attendants. Esp the english guy."
Cons: "Once again just some measly pretzels."

Cons: "very little food! chairs r too tight and tv screens r rediculously small... no usb adaptors to charge ur phone, no toilette seat covers!"

Pros: "Nothing"
Cons: "Nothing was impressive at all"

Cons: "The fact that even water is for purchase is disgraceful"

Pros: "British Airways code share is always nice"
Cons: "Older 747 not quite as nice as the Dreamliner but it made it!"

Cons: "Nor too many good movies to choose from. I get it , row number 47, don't expect any 1st class comfort, but still, i was glad to land in Denver. Started to run out of sitting positions that didn't hurt."

Cons: "Flying is uncomfortable and painful. The seats are thin with little padding. I kept getting poked and prodded by the person in the seat behind me, and it wasn't even a little kid kicking the seat. I have a problem with my foot, and there is piece of hard plastic or something that runs the length of the plane, under the aisle seat. I had to make sure my foot didn't rest on time because it was painful to my foot."

Pros: "Fight was on time. BA Crew always do a nice job."
Cons: "The entertainment on the flight didn't work. It is not easy to have two small kids on a 9 hour flight when the entertainment system isn't working properly. We did bring our own items to entertain our kids but with the limitations on what you can carry on we were banking on them being able to use the in flight system."

Pros: "Everything was first-rate"
Cons: "The inflight movie service is, in our opinion, worthless because of the noise. If you had closed captions available that would work."

Pros: "I'd like to mention Ramon, a crew member on the flight, who was extremely helpful and kind. Also, the food was quite good."

Pros: "The first class steward who helped us when he didn't need too. The free films."
Cons: "I flew British Air in the past and had excellent service. I actually would have paid a bit more to choose them as an airline. No longer! Horrible service. Our stewardess was rude and unhelpful. Best example, when my husband turned in the remains of his last meal, something had leaked over his tray table. She didn't bother to help. He luckily had some extra napkins. She watched him clean it up and then left without taking the soiled napkins. Thanks. The meal quality was poor on the international flight. American handled the start of our vacation. Such a superior international flight quality compare to British Air."

Pros: "Service, comfort"
Cons: "They lost my bag due to flying a 3rd party "Vueling" and did not add my FF# and would not do it at the airport so now I have to sort through online pages and phone queues to do something that definitely should have been feasible and included at airport (I added it on my outbound flight but because of this 3rd party being the originating operator of my return flight it was not included on my return)."

Pros: "upgrade"

Pros: "The staff was friendly. The food was great. There was plenty of entertainment to choose from."
Cons: "N/A"

Cons: "Antiquated and glitchy entertainment system on the 747-400"

Pros: "LOVED the folks on this airline. So nice and accommodating."

Pros: "Crew were attentive and competent."
Cons: "The food was just not very good which is a bummer since it was a long flight."

Pros: "Flight on time. Seats/pillows/blankets were clean. The crew was professional - high quality interaction that makes the difference between BA and other airlines. (other airline crews can be abrupt, rude, ignore passengers, especially with getting water outside of service times, standing while waiting to use lavatories, etc.)"
Cons: "Some garbage from prior flight in seat pockets of 2 seats we occupied. Entertainment system is a bit clunky, film choice not very good."

Pros: "Fantastic chicken curry! Best airline food EVER! Nice stewardesses too....."
Cons: "I suppose I expected a slightly bigger toilet on a 747, but no biggie."

Pros: "I liked the polite and friendly manner of the flight attendants."
Cons: "The flight was delayed for over an hour after boarding, and the temperature was uncomfortably warm. Even after takeoff, it took several hours for the temperature to cool down to normal. I have not experienced this before and wonder why it took so long to cool. All of the passengers around me were complaining of the heat.."

Pros: "Nothing"
Cons: "Our British Airways flights were cancelled going & returning on the trip. This resulted in rebooking in both directions, at different points in the trip. The cancellation on the return trip was extremely inconvenient since we didn't have a phone to contact BA. After wondering the airport on the day of our departure, for a BA representative that could help, we were directed to a ticket sales office. Then after waiting for another one (1) hour in a line, the BA representative rebooked our return flights. This was not a good way to start or end a trip!"

Cons: "Boarded and our 3 year old fell asleep. sat on the plane for 50 minutes before being told to get off the plane. Ended up with a delay of almost 6 hours. sorry, very frustrated."

Pros: "I liked the food and getting the complimentary wine for dinner, the free movies and we were able to change our seat assignments easily."
Cons: "Our flight out was delayed 7 hours and we still had to be at the airport for the original departure time. We were uncomfortable in our middle seats on the way out as well. Also, it would be nice to get refills on coffee or tea during the flight. I asked for a second cup of coffee and was turned down."

Pros: "In flight service and food were excellent"
Cons: "My TV monitor didn't work. Crew couldn't get video on demand to reset."

Pros: "Food, fast and efficient boarding, only a small delay, fairly comfortable, and great entertainment!"

Pros: "Direct service from Denver to Europe is great."
Cons: "The economy seats are rather cramped for a flight that lasts 8-10 hrs, and the price difference for more comfort is often is prohibitive."

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"

Pros: "Boarding was ok"
Cons: "No entertainment screen and no free wifi. They let you sign in to their entertainment on the phone, but first of all the screen is small and it drains the battery of the phone and not comfortable. It would be great to have screens in all airplanes. Also, they give a pretzel and a bottle water, no other snacks and soft drinks are available."

Cons: "Feed me"

Cons: "With Covid they could hand out a bag containing water and a snack."

Pros: "I was lucky enough not to be put into a middle seat or next to a stranger during this pandemic."
Cons: "No social distancing and no enforcement of wearing a mask properly. Wearing one on your chin or half of your mouth with your nose hanging out needs to be corrected. Empty seats should be utilized for social distancing regardless of fare. First class and the back half of the planes were practically empty while everyone was in the center. We should have been allowed to spread out."

Cons: "Less crowded."

Cons: "How come I always have a beautiful and talented flight attendant? She was perfect!"

Pros: "Fasting boarding"
Cons: "didn’t care for the food given out. Didn’t really get to know the staff."

Pros: "The crew was nice"
Cons: "There was maintenance happening on the plane after everyone boarded. It was a long wait on the plane and it could have been better if that was done before boarding."

Pros: "I was moved up to seat 9E from 16E move leg room makes a difference"
Cons: "I had started a movie on the earlier flight but I could not finish it because it was not offered on this flight"

Pros: "Nothing was enjoyable."
Cons: "The flight was 4 hours late to leave and American did nothing to try and remedy the situation. Unacceptable that we are this late. I missed my meetings and they won’t offer any kind of voucher for future travel. But yet we have to pay for change fees!?!? I will absolutely avoid flying American."

Pros: "Left lake but still made it on time"
Cons: "Aircraft was hot. I volunteered to check my carry on and on other airlines they’d let you board early but the lady just made excuses. It’s fine if that’s policy but I don’t appreciate made up excuses."

Pros: "The steward was super friendly."

Pros: "The plane was super comfortable"
Cons: "Long check-in lines in Denver - there were two sky caps outside who had no line which allowed me to reach my gate in time. Otherwise I may have missed my flight"

Pros: "The flight was wonderful,even with delays American Airlines was horrible at accommodation and food vouchers"
Cons: "Not putting us on cots in MIAMI, food vouchers and overall it was an AA issue that was horrible"

Cons: "The airline"

Cons: "To many delays."

Pros: "Crew was super nice The plane was clean with a lot of power outlets, good WiFi, etc"
Cons: "We were almost an hour late"

Cons: "Boarding was haphazard"

Pros: "Great service and sweet attendants"
Cons: "Person next to me was a little large and it was uncomfortable."

Pros: "We arrived to LAX at the same scheduled time and the pilots were very informative when we might have turbulence."
Cons: "Head phone jack was broken, was told by one attendant that they would fix it. He never came back, told someone else and they said sorry, there was an open seat 6 rows back. Was not going to have my son sitting by himself. Knowing that you have to check many things prior to the flight, maybe have a back up plan for something like this."

Cons: "Delayed for mechanical."

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."

Pros: "I got to japan"
Cons: "I paid for Japan airlines because they are a clean airline and service is superior. Watch the fine print. My seat was dirty crumbs and leftovers left in the pouch and folding tray."

Cons: "The fact that it was a night flight and the lights were on 75% of the flight. They need to allow drinks to be an option."

Pros: "Everyone was nice"
Cons: "No gluten free snacks. Flight was late"

Pros: "Early and friendly."

Pros: "Great service"

Pros: "On time, even with de-icing. Very empty flight, so lots of room to spread out."
Cons: "The older md80’s that AA is still flying are really showing their age. It will be nice when they update their fleet."

Pros: "This is a modern airplane with great features"
Cons: "The seats are way to narrow"

Pros: "The flight was ok with no issues once we were in board"
Cons: "We hot there in plenty of time for our 7 am flight and were bumped to a 12.30 pm flght. When we returned to book in we were being accused of missing our flight. Finally got vhecked in what a pain"

Pros: "Friendly crew, comfortable space, good snacks."

Pros: "It didn't take long for anything."

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."

Pros: "We didn't crash."
Cons: "No safety briefing for infants, rude gate staff, primitive fleet, terrible customer service at all levels."

Cons: "Ground crew was inadequate and unorganized. Ground crew caused a late flight to be even later. Plane was overbooked and the ground crew was more interested in filling the flight than accommodating Advantage Member seating."

Pros: "Friendly people, seemingly short flight, as I slept part of the way. A lot quicker than driving from upstate New York."
Cons: "Again, hard to hear announcements, and I was unaware that non-alcoholic beverages were complimentary. Ride was a little rough, awakening me numerous times"

Pros: "Food and crew were excellent. In flight entertainment vast."
Cons: "Seats were terribly uncomfortable. I was sandwiched between two men in an aisle seat of 4 and our arms were bumping into each other the whole time because the seats were smaller than the people. It was the most back and lower lumbar discomfort I've had."

Cons: "They rebooked my flight to one with an overnight layover and informed me via email with no explanation. I rerebooked it myself to one which left the next morning and arrived sooner than their rebooking."

Pros: "Overall friendliness of the crew"

Pros: "They provided tablets."
Cons: "They changef aircraft for an old one. Bc Seat really uncomfortable. Not dorect aisle access. No avod. No wifi. We were waiting 20min at the aircraft door waiting to enter."

Pros: "The crew was one of the best flight crews I have ever met! We had many of the same attendants on the flight back to MIA, as well. Give them raises!"

Pros: "Bought a ticket from Alaska Air, but got farmed out to American, If I wanted to fly in American, I would have bought a ticket from them. This also made checking in a lot more confusing..."

Pros: "I liked that the plane was clean, that the staff consisted of somewhat normal, more mature people, and that water and carry-ons are free."
Cons: "I felt that having to pay $50 extra for a seat when I checked in was pretty deceptive and unethical. I think most people would agree that when they purchase a boarding pass, it is assumed that it includes a seat. Having to pay extra for a seat was something I did not plan for and it was out of my budget, but I had no choice, because I had to get home somehow! I'll be going without groceries this week due to this unplanned expense."

Pros: "The crew was fantastic, the flight was smother and on time, boarding was timely"
Cons: "The plane was older with a poor entertainment system"

Pros: "Not a good experience so nothing"
Cons: "AA failed to allow me to check in at initial arrival in Grande Prairie airport so I had to rush to get a boarding pass in Calgary where the AA agent told me it was not an AA problem and sent me back to WestJet. WestJet discovered that it was an AA problem and returned me to the AA counter where it was resolved. Then I had to rush to catch the flight and missed any opportunity to have a decent lunch between flights. Then there was no food offered on the AA flight to Dallas."

Pros: "The flight was on time, and the crew was friendly."
Cons: "The boarding was very disorganized and took a long time, and there was no silverware on board, which I needed."

Pros: "It was great!"

Pros: "N/A"
Cons: "It took so long for me to leave this airport. 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 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."

Pros: "Perfect"

Pros: "Premium economy service and seat."

Cons: "I was made to pay for my carry on because of weight. I didn’t understand that when I booked. I am also certain that many other carry ones were more than 12 kilos."

Pros: "Not much"
Cons: "Stewardess never smiled once! She was approx age 45 and should know by now how to be professional. Not the start to a vacation anyone would want."

Pros: "Considering the thousands of passengers who saw their flights cancelled because of the grounded 737 Max’s the fact that I was on hold for only 30 minutes and then got rerouted for the next day is amazing! Thank you Air Canada."

Cons: "No good"

Cons: "Terribly small seats"

Cons: "Seats are always a pain in the butt Wifi has never worked for me -slow and keeps dropping"

Cons: "Small plane, no room for cabin luggage"

Pros: "The pods were great on 777"
Cons: "Couldn't plug in CPAP"

Pros: "Only thing good was the brevity of the flight."
Cons: "The aircraft was dirty and ridiculously cramped. Air Canada undermines its brand by flying planes like these."

Pros: "The service"
Cons: "Nothing so far, thanks."

Cons: "JustFly did not release my coupon to Lufthansa or Air Canada, and so I was nearly prevented from flying."

Pros: "Entertainment"
Cons: "My seat was wet and i had to wait quite a while for it to be rectified. I asked to sit on a crew seat at the back of the plane and was told that i would break it. I found this rather disgusting . Seating plan is very crammed like sardines"

Cons: "Late flight the crew did.t care and many people missed connections. The customer service at the airport desk was understaffed slow and rude. They we're not helpful in trying to get new flights booked and I felt like it was asking a huge favor even though it was Thier delayed flight that made me miss my connection."

Cons: "I bought my ticket with Air Canadafrom Vancouver to Calgary then connected with Lufthansa from Calgary to London UK. Unknown to me I could not find the flight because it had been changed to an AC reference flight. With a very short time for the connection I did not know where to get my boarding pass as my flight with Lufthansa was nowhere referred to ! Not which gate to go . Why not put it in the ticket that Lufthansa and Air Canada work together and that both flights ref should show !! It would avoid a great deal of anxiety . Only offered 1 round if hot drinks over 9 hours ! Departure delayed by nearly 60 minutes"

Cons: "No offer to have transportation to gate. I am disabled and had a very long walk."

Cons: "never on time, late flying both way's"

Cons: "Delays"

Cons: "Left our luggage in Montreal!"

Pros: "Seat is not too crowded"
Cons: "No snacks"

Pros: "Confortable"
Cons: "N/A"

Pros: "Staff were friendly"
Cons: "Seats were narrow and sitting in aisle seat you were constantly hit every time cabin crew took trolley up / down aisle. Woke up by cabin crew banging into me."

Cons: "No end to delays."

Pros: "Nothing."

Cons: "To small of plane."

Cons: "They wouldn't seat us together"

Pros: "Meh."
Cons: "Video display didn't accept touch input so didn't work at all."
