Comfortable. Friendly staff.

Pros: "Nothing it was cold no blankets."
Cons: "Flight was not on time. Delayed 5 hours."
Pros: "right on time; cheerful kind crew! pilot kept us updated but wasnt irritating"
Cons: "food was a bit of a strange mix...some parts delucious; the rest just weird... also with CV-19 at large would have loved to see the crew wipe down lav/doir handles once or twice!"
Cons: "Seat cushions feel a little flat."
Pros: "Boarding was quick. Crew was friendly and professional."
Cons: "No faults. Perfect flight."
Pros: "A full complément of movies to choose from"

Pros: "Good selection of movies streamed to phone"
Pros: "I have never been so comfortable"
Cons: "Enjoy Alaska air"
Pros: "On time & food is reasonably priced."
Cons: "More choices of food for 3.5+ hours flight."
Pros: "Friendly crew. Great movie selection through gogo inflight entertainment!"
Cons: "There was a lavatory directly across the aisle from me"
Cons: "Nothing - most excellent flight!"
Cons: "I don't normally leave reviews, but words really can't describe the nightmarishness of what should have been a quick four hour flight from San Francisco to Washington. Seats for my wife and I were not where I had reserved. Plane had one working lavatory for a cabin of 150 economy passengers. This resulted in a line that stretched the entirety of the single aisle of the plane for the majority of the flight. The second toilet simply had a piece of paper with sharpie that read "DO NOT USE!!" There were two attendants, one of whom wore a t-shirt and was mostly indistinguishable from the passengers. Didn't get so much as a cup of water until over two hours into the four hour flight. No snack, but that's the least of my complaints really. The attendants spent most of the flight in the back of the plane discussing their new vacation lottery and where they were going to go out drinking when we landed–I know because the rear of the plane was where I ended up, forced to smell the single working toilet, in a seat that didn't recline."
Pros: "That there was still a little bit a Virgin America still present! Love entertainment is available an absolute bonus that I wish traditional Alaska planes started installing!!"
Cons: "The entertainment of no headphones available and most headphones are now Bluetooth presents a problem. No snacks offered!!"
Pros: "Our flight attendants were fantastic."
Cons: "The application I had to download had cookies."
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: "I was unable to catch my flight and I called and the lady kn the phone was not helpful and rather rude. Was unwilling to help me figure out a solution to changing my flight plans"
Cons: "was unable to catch my flight and I called and the lady on the phone was not helpful and rather rude. Was unwilling to help me figure out a solution to changing my flight plans"
Pros: "Everything was great! This was my first time flying Alaska Air and I could not have had a better trip! Everything ran according to schedule, I was comfortable during the flight, slept the entire time, staff was great!"
Cons: "The woman making announcements did not specifically announce the duration of the flight as we were departing. I was able to figure it out on the map option on the screen, but I would've liked to hear it verbally. Only suggestion I would have is an announcement on the plane for which baggage claim belt our luggage would come out of. I may not have heard it though, if there was an announcement. It was not difficult at all to figure out once I was in the baggage claim area, however if this was known while we were still on the flight, I prefer to know this info!"
Pros: "Once we got going, the Capt and crew did make up for lost time& that was greatly appreciated!"
Cons: "We waited and waited in the airport before boarding......having no idea what the hold-up was."
Pros: "Usually we fly United on a direct flight to PDX. That flight is no longer available so we chose Alaska to Seattle. Their entertainment and internet actually works making them a better option than United. Flights were on time, crew was friendly, and the aircraft was clean. No complaints with Alaskan, and actually happy to change airlines after years of being with United even though it is not a direct flight to our destination."
Pros: "Yes, they My have lost it but they delivered it to make up for the mistakes."
Pros: "Alaska is great in all ways"
Cons: "2+h delay"
Cons: "Chargers didn't work on either flight"
Pros: "Great service for an affordable price!"
Pros: "Nice and easy"
Cons: "Nothing"
Pros: "Outlets in the planes!!!"
Cons: "Delay on one flight"
Pros: "Boarding was efficient, seat was comfortable. I appreciate that food and drinks were offered often."
Cons: "One particular flight attendant purposely ignored me when I tried to ask for cream and sugar for my coffee which she did not offer when handing out drinks. Then she looked right at me twice as I tried to give her my garbage which she was collecting, but she ignored me again and left me holding my garbage until a different flight attendant came much later and took it without incident. It made me wonder if it was because I looked Asian- she was helpful and polite to the white women next to me. I was polite and was not being difficult in any way. I'm half white, but was often treated like this in Illinois when I was growing up. She should have been professional and if she had I would have rated the trip as excellent."
Pros: "Arriving in Seattle my bag was waiting for me at the claim area. After 45+ years of flying around the world that was a first. But something happened before we took off. The gentleman in the seat in front of me had packed some oxygen bottles in his bags and a handler came onboard to address this. He was polite and very understanding that the man was meeting a cruise ship in Seattle and needed them as life support. The handler took an address from him and said he would take the bottles to Fedex near the airport and sent them to him. And the passenger could send him the money later! I thin k the handler's name was Bob. He needs a commendation foe going the extra mile for a passenger! Find him and buy him dinner."
Cons: "Having to get my seat assignment at the gate just increases my anxiety with the entire flying experience. Stop it. I get there 1.5 hours early to wait at the gate uncertain of weather I will be flying that day. As usual with all airlines seat comfort was non existent."
Cons: "Check in staff at Assistance counters either had problems with their computers or couldn't understand reservations. We had a pet for which we had paid for round trip reservation months ago, yet agent took quite awhile to reconcile our reservations. We stood in line for nearly a half hour during which their were very long lines at each check in point and at least one or two agents left on breaks while the lines were still very long. At Burbank the agents were fast, accurate and there were almost no waiting. The flight itself was great and the flight attendants were excellent; but not impressed at all with check in at Seattle."
Pros: "The crew was great. They were pleasant and helpful."
Cons: "We were on row 33 d,e, & f. Seats d & e would not recline. The button on seat d was broken. As annoying as that was, there were 3 unaccompanied minors sitting in front of us. Two of them were fine. The third one on the isle seat was up and down, in and out of his seat the majority of the flight. I couldn't sleep. This was my second flight of the day after staying in Seattle for 7 hours waiting between my flights. The kid was loud and it seemed like the crew couldn't correct him. He just did as he pleased. I wasn't the only passenger who had a problem with him. And apparently the crew did as well. I paid a lot of money for that flight and he ruined it for me. If they are going to fly children like that, the crew should be able to correct them so the other passengers can have a pleasant flight."
Pros: "The staff was really friendly, easy boarding, great fast baggage claim. overall great!"
Pros: "Seats were comfortable but they need to recline or have foot rest. When I missed the flight your CS was excellent her name was Whitney and she was in Seattle.."
Cons: "Should not charge for WIFI service in the air"
Pros: "Alaska Airline personal are professional and helpful."
Cons: "TSA is a disgusting experience, though I understand it's importance in this unsafe time in history. But, the TSA personell often seem to be bickering among themselves while they are suppose to be working."
Pros: "The customer service got us on the next available flight. Didn't charge us for our baggage (which they could have). Staff were helpful and realized that we were bone tired (after being awake for over 30 hours). Flight was easy. Crew was nice. Easy access to baggage when we got to PDX. I love Alaska Airlines!"
Cons: "Nothing. They got it all right."
Pros: "I loved the free chat and free entertainment! It made such a long flight go so much better and goodbyes and travel easier knowing that I could communicate on the go! For someone with social anxiety, being able to talk to loved ones when I was going through things was the best experience ever! Thank you so much!"
Pros: "Straightforward. Love that Starbucks coffee is offered! Also love that you can charge devices. The inflight entertainment option works for me; I usually come prepared but I was happy to pay to watch a movie, although the cost seemed unnecessarily high."
Cons: "There was quite a bit of wait at boarding time while standby seating was sorted out. I wasn't sure why ticketed customers could not board on schedule; instead, everyone was standing around at the scheduled board time while names were announced, etc."
Pros: "Alaskas great cheese plate"
Cons: "The heat was high, we asked the male steward many times to request the heat turned down, people were removing as much clothing as possible. It was very hot and sticky and smelly. The descent to landing was to fast when near the runway, and we crashed hard like a carrier landing. I would inspect the gear and wing spats for cracks. The fuselage bowed like a banana, it was evident looking down the tube sitting the back. How about a breathalyzer or something, everybody knows the drunken pilots, the can't be fired and they know it, so it takes years to sober them up at our expense. The pilots who've been caught drinking are not trying to get better, they just whine that the others who haven't been caught yet are even worse drunks. Everybody who flys on Alaska has heard it from the same old Alaska born drunken pilots. How about less drunken bush piloting and get your drunken pilots who've been busted in the last few years to shut up and stop telling everyone that all Alaska pilots are drunks as defense of there drunkeness."
Cons: "Wifi didn't work. Very dissappointing."
Cons: "The plane had to turn around halfway from Seattle to Vancouver due to a mechanical problem. We all later got an email saying we'd receive a discount on future travel because the airline deemed the delay "preventable." We got a second plane quickly, on the second boarding process the gate agent failed to do preboarding. I'm on crutches at the moment, so this meant more time on my feet manoeuvring around "elite status members" than I would have liked."
Cons: "I carry photo equipment in a carry on bag because of expense, damage control and temperature control. Unfortunately I can not leave it for baggage people to handle (although I would love to.) When I got my carry on to the greeting flight attendant I explained I had just finished a shoot and I was sorry that I needed to keep the bag as carry on. Flight Attendant: there was nothing she could do and I needed to go back down the stairs, even though people were still boarding and leave it with the baggage people. Me: "In the past the flight attendant put the bag in that closet." (I pointed to the locked closet where they keep their bags.) Flight Attendant: I cant open it because it's locked. Me: "The key is kept there." (I pointed to where the key is kept. I know because I've done this trip so many times before.) Flight Attendant: "See if it will fit under your seat." It did... but I had my knees in my chin for the entire flight. Thanks, Ann"
Pros: "It was a great flight. The attendants were great. The captive was informative."
Cons: "They needed a little more space in the seats and the Isle could be a bit wider also. When the carts were going threw it did limit the restrooms. But overall it was a great experience."
Pros: "The flight took off on time and got to the destination on time. It is a great experience. The flight attendants are nice and friendly as well."
Pros: "Friendly and calm professionals in the "assistance" line. The ticket kiosk did not recognize my confirmation number or name so I was instructed to wait in the assistance line and I was furious- swore I'd never fly with Alaska again- but then the ticket agent was fantastic, calm and helpful and helped put me in a better mood. Overall flight was great. Felt safe, hardly any turbulence and friendly flight staff. Flight was on time. No delays."
Cons: "No screens on the back of seats with free entertainment. I don't like paying extra for entertainment. I wish you had good vegan food options."
Pros: "It was fast and friendly. They took a lot of guesswork out and made us feel safe."
Cons: "The planes were a bit small for flying 6+ hours. I started getting restless at having to sit in the same position for that long."
Pros: "On the ground ..TSA said I needed a new boarding pass..3 kiosck wouldn't. Work. Friendly re sent me to Alaska desk where they printed me a new boarding pass but when I went to TSA. I had no passport. Sooooo..back to t he Alaska desk and a wonderful rep named Diane helped me hunt through all my "stuff"...then began talking to all reps helping process passengers. She never gave up. And found my passport at the desk that had made me a new boarding pass. I was so upset I couldn't think straight but she did!, many thanks to this kind lady."
Pros: "the seat confusion was a hassle but the crew was nice about it."
Cons: "the flight was oversold and i didn't get a seat assignment until the last minute. Then the seat they gave me was already booked to someone else, so i had to wait again on the plane to get a seat. on my outgoing flight to seattle a few days prior, i intentionally didn't check a bag because i had a late arrival and early work the next day, was forced to check it on the plane and then they lost it for an hour after i landed so i didn't get home until 2am. frustrating, but again the crew was nice about the mistakes."

Anyone that purchased a Delta 1st Class seat should have access to the Delta Sky Club. My wife and I purchased 1st Class tickets for a Delta flight from SeaTac to Washington Dulles but were denied entrance to the SeaTac Delta Sky Club because we did have an American Express card.

Pros: "Very nice plane"
Pros: "Accommodating a lot more than American Airlines."
Pros: "Nothing"
Cons: "13 hour delay"
Cons: "Roomier"
Cons: "Filthy plane, and delayed too long"
Pros: "Crew was very friendly and efficient. Flight was pretty smooth."
Cons: "On time departure would have been nice. 2.5 hours late."
Cons: "Announcements were too loud in earphones (could damage ear drums) and entertainment was turned off while waiting 30 min for the gate to open."
Cons: "It was canceled"
Pros: "The crew really kept us updated on the many delays."
Cons: "There were SO many delays and they kept changing. At one point we got on and off the plane."
Pros: "The crew was amazing."
Cons: "Cleanliness"
Cons: "We experienced a one hour ground delay at Sea-Tac which was unrelated to our airline. The pilot kept the passengers informed with timely updates, and we finally departed about when the pilot predicted we'd get away."
Pros: "I was upgraded to Comfort+ and the seat next to me was left vacant. That was a great flight!"
Pros: "Nothing"
Cons: "Nothing"
Pros: "Seat was decent and only a $10 upgrade. Worth it!"
Cons: "Wasn’t clear what boarding group was up. I don’t usually fly delta so maybe I’m just not used to the system but something on the video screen at the gate saying where they were in boarding would have helped. I wasn’t the only one that seemed lost."
Pros: "The crew was dealing with NOVA/DC residents"
Pros: "The food was improved and the seat was comfortable."
Pros: "Early departure"
Cons: "Absolutely nothing"
Pros: "Boarding was quick"
Cons: "No entertainment, plane was small"
Cons: "First delay notification: 1 hour 20 minutes 1 hour later, Second delay notification: 3 hours 15 minutes 2 hours later: Third delay notification: 3 hour 50 minutes Fourth delay notification: 4 hours 25 minutes Fifth delay notification: 4 hour 32 minutes No explanation for reason. Last time flying Delta."
Pros: "Excellent service in most every respect! Boarding was easy, accommodations were quite ample, food was great, and the entertainment was plentiful."
Cons: "Slight problem with making my seat into a bed, which wasn't fixable. Movies were good, except for the trailers before and after each, which seemed to take forever! Didn't get the seats my wife and originally booked with China Southern/Delta, but the substitution was quite adequate! Problems with checking in on flights, as neither airline seemed to be able to deal with this split ticket! But they tried very hard to make thing up to us, which goes a long way to making us feel like we are valued customers!"
Pros: "The service and the crew were extremely courteous polite and professional ."
Cons: "As it is an all flights just not enough leg room and a very tight chair."
Cons: "Missed connecting flight because the first flight was delayed by 2.5 hours. I didn’t get the comfort seat I paid for because of this and was not given a refund for it."
Cons: "Kayak a howed my gate as something that didn’t exist at the terminal. I went to a kayak help desk to have a ticket printed that showed my TSA precheck because it wasn’t showing on my mobile ticket, and no one was there to help. I waisted for 10 mins. It then took me nearly 2 hours to get through security. I asked if I could get through quicker and was told I could not, despite it being passed my boarding time. I then ran to my gate where I waited for another 10 mins (no one was there, again) and then an employee came out and said they couldn’t let anyone board once the door was shut. He then directed me to the delta help desk (there was at least 20 people behind me who missed their flight). I then had to pay an additional $75 to get a later flight. The whole experience was awful and I’m disappointed with Kayak and the gate confusion, but mostly Delta and the lack of customer service."
Pros: "The flight for getting us therw"
Cons: "No food and no entertainment"
Pros: "I think they flew so fast. We could land almost on time even though we departed a hour late. Airplane was new and clean."
Cons: "Boarding was chaos. They overbooked 25? 45? Anyway, they are in panic. They tried to request ppl to take next day flight by giving away 300 gift card etc. the ppl who were told there are no seats upset and arguing at the gate. Flight was delayed for one hour. Once we are on airplane, they are still shuffling seats around, so ppl cannot move forward. Just standing there for 10mins waiting for things to settle. Flight attendants did not give us a headphone. (I have a headphone for iPhone X so I could not connect it to their entertaiment system.)"
Pros: "This was our first time flying Delta and it was a very pleasurable experience. Boarding was very straight forward and the seats allocated comfortable. A surprise for us was being asked if we would like to move seats from the back of the aircraft to Comfort Economy (we think it was to do with weight balance! but appreciated very much none the less). The flight attendants were very professional and helpful, as you would hope all attendants on all airlines would be. We'd gladly fly Delta again anytime."
Pros: "Aside from the issue where we had to deplane and wait for another plane, the flight and crew were great."
Cons: "The delay from the plane problem."
Pros: "Nothing really"
Cons: "Flight delay further to the 30 minutes additional 20 min due to crew being not there"
Pros: "Entertainment was good."
Cons: "The crew was very rude."
Pros: "Almonds"
Cons: "Seat, did not get upgraded"
Pros: "Friendly staff staff, smooth boarding experience, DC+ positive experience"
Cons: "757-200 outdated for having spent 10 hours on that same plane (stop but no plane change) having flown shorter haul flights on many updated 757 was disappointing."
Pros: "The food was fine and it was on time"
Cons: "The airplane back by the bathrooms were littered all over the floor. Needed to be cleaned. Their were no seat covers in toilette and it was only 2 hrs into the flight."
Cons: "No drink or snack service. No trash pick up. No option to purchase or rent headphones"
Pros: "The crew was friendly and attentive, and the flights were punctual. I was assigned a good seat, and I appreciated the meal, as i was going to arrive in Mexico very late. I also enjoyed the entertainment options."
Cons: "I really have no negative comments."
Pros: "Nice plane, smooth flight, flight was on time in spite of the disaster in Houston."
Cons: "Well, even United brings a tray of waters on the short flight from Portland to Redmond. Hard to believe it was impossible to serve some drinks on this 1 hour fairly empty flight from Seattle. Also, when taking off the plane surged and slowed several times. I had to wonder if the pilot was in training?"
Pros: "Food selection and quality were fine. I also enjoyed the entertainment options. Seat area was comfortable and spacious."
Cons: "The flight attendants were uniformly rude and nasty to passengers from start to finish. As I boarded, I asked for a piece of art to be stored in the wardrobe compartment. This was treated as an inconvenience. During and after boarding, flight attendants addressed passengers rudely when encouraging them to take their seats in a timely fashion. Later, when my seat mate politely asked a FA to repeat the food options, she asked, "Excuse me?" several times and seemed very irritated to have to repeat the choices for him. Also, near the end of the flight, a pillow was on the ground and a FA asked those seated in my row to pick it up. We responded that it wasn't ours and she said something to the effect of, "Oh yeah? So how did it get there?" (Maybe because someone else dropped it and we didn't notice?) The FAs seemed irritated to serve passengers at all. Each time they passed through for beverage or meal service, I felt like I was imposing on them. I have never witnessed anything quite like it. Makes me wonder why they were all so upset and and felt it appropriate to speak and act disrespectfully toward customers. (Delta, do you have any insights?) I hope they all got a good night's rest after that haul."
Pros: "The flight was fine, attendants we're good, entertainment options are great."
Cons: "Boarding. It was probably the worst I've seen. A shared intercom system between two gates (b7 and b7a), boarding flights around the same time and our flight beginning portions of pre boarding with no announcements caused mass confusion. Passengers lining up to go before they should, bumping into each other, no info or corrections over the intercom. The gate agent yelling at people to move aside. Overall terrible gate agents and terrible set up. Flight crew was great though."
Pros: "everything was very nice"
Pros: "Nothing"
Cons: "The fact they wasted two days of my trip with my son travelling from the U.S. to China because they didn't know about transit visa regulations. And so far they offered a 75 dollar voucher for participating merchants. Unacceptable"
Cons: "As a Platinum AFK/KLM Skyteam member I was NOT allowed to use the Delta Lounge. On the flight the meal choice was poor and the staff were not really geared to serving regular clients. The movie choice was poor. I expected better!"
Cons: "Late and missed my international connection"
Pros: "Free entertainment and free food was unexpected and very welcomed, especially given the trend of charging for more and more features."
Pros: "Comfortable flight, ample leg room, and the chairs were pretty plush. Comfort+ is pretty nice"
Cons: "On my first flight they forgot to turn the wifi on. I have unlim data but obviously can't use while in air; no big though."
Cons: "*Again, my first choice of main off the menu, in Delta One, had run out. *Not a fan of the Delta One seats."
Cons: "The air conditioning was broken so it was sweltering the whole time. Staff didn't even mention it or apologize. No leg room. Bags took longer than 20 minutes to arrive but we didn't make a fuss since we were just glad to be finished with Delta. I'll never fly Delta again even if it costs me more."
Pros: "We had a whole row of 3 to our family, so we could put the armrests up & the kids just laid down in our row (on me, & each other) and slept most of the flight. The flight crew was very understanding and helpful with my kids who were just with me on an intl flight "daddy duty.""
Cons: "Since it was a flight from Seoul, Korea to Seattle; it would've been nicer if all the movies had Korean subtitles-- my 4-yo boy who only speaks Korean, couldn't make it through more than 15 mins of a movie because he couldn't understand (of course, some of that is due to age & short attention-span). But he kept saying, "I hate English" in Korean while trying to pick a movie. Also, I'm 6'2"; so while it was nice having the whole row for my kids to lay down in-- I was cramped and uncomfortable the whole flight, even moreso with Delta's seats being closer together than on other international carriers I've flown."
Pros: "Delta made sure my husband and I had seats together and my husband was thrilled to have a window seat. We took off and arrived earlier than scheduled so we didn't have to run to catch our connecting flight."
Cons: "Everything was perfect. Nothing negative to report."
Pros: "Comfortable seats and incredible kind staff"
Cons: "No food, drinks, or entertainment. But it was an extremely short flight."
Pros: "Fast boarding, everyone nice."
Cons: "Wifi was yo and down the whole flight, about 20 times, so kids were not entertained."

The plane is old and really small. Crew was great

Pros: "The food and the crew totally good"
Cons: "Maybe the toilets, need to be clean at least once in a flight"
Pros: "Crew was super nice"
Cons: "Airline to be more user friendly with connecting to free entertainment"
Pros: "Crews are fantastic. Just only assigning seat u need to buy so that you seat besides of your companion."
Cons: "If the travelers has 2 to 3 more companion let them seat together."
Pros: "Crew was efficient and pleasant making for a good experience."
Cons: "Nothing"
Cons: "Original flight came in 1.5 hrs late. Missed connection, then sat on the tarmac for 2 hrs before taking off because the pilot was late."
Cons: "Paid for First Class so I could sleep on this red-eye. Wasted my money. Seat was uncomfortable, legroom in my bulkhead seat was horrible. I can sleep anywhere...make that ALMOST anywhere, now."
Pros: "Nothing. I missed a family members funeral and no one at the airline cares. I ended up staying home because the flight was delayed 8 hours."
Cons: "Customer service didn't even try to find connecting flights and informed us that there were no other flights going to Phoenix. Which was a lie. I will never book with American again."
Cons: "Other than at meals, No crew around to distribute water on a 9-10 hour flight. Crew not very nice when we were asking for water. Completely dehydrated on arrival. Ground crew very charming."
Pros: "Flight attendants were two hours late"
Pros: "Attentive crew. Traveling with 2 seniors in their 80’s. Thank you."
Cons: "Nothing. Perfect."
Pros: "Crew was very friendly"
Cons: "Seats were extremely uncomfortable, and hurt my back very much."
Pros: "It’s not like it used to be. U S based airlines lag behind their European and Asian counterparts"
Cons: "There’s always room for improvement. Too much to list here"
Pros: "The flight got me there"
Cons: "WiFi was too slow to be able to watch anything. Seat small and uncomfortable. Flight attendants not friendly."
Pros: "Even though looked like I had selected a seat assignment they were not booked. On first leg of trip had to wait until a couple agreed to be bought off their seats before we could be boarded. Very misleading."
Cons: "Boarding could be improved if they would start boarding from the back of the plane to the front after boarding 1st class and Priority this way people would not block the passage when putting their luggage in the top compartments. The crew was not very helpful because I almost went into a hypothermia condition because the air in the cabin was extremely cold. When I ask for a blanket one of the stewardesses said that AA would no longer have blankets in flight which I prove it wrong when I saw in the flight Mai-SDQ blanquets all over the cabin. The soliton they gave me was that they would ask the crew to raise the temp in the cabin, I had to make the request three times and I had to tell the stewardess that if not raising the temperature in the cabin I could have gone into an emergency hypothermia crisis. I had to take another shirt from my carry-on to put it over my shirt to warm me up."
Pros: "On time and the staff was great"
Cons: "Nothing"
Cons: "Flight was delayed for whatever reason. Did not give us a reason why. Also boarding was very haphazard. They just boarded all groups at once to try to make up some time. Almost did not make it to our connecting flight in time"
Cons: "I didn’t take my outbound so they cancelled my return flight without notifying me. I had to pay $200 to buy my seat back. American is about as bad as spirit.."
Pros: "For this flight I was seated in first class (I scheduled it this way; it wasn't due to a last minute upgrade) and the flight attendant was very personable and attentive :-) Service was wonderful and the meal was great! Of course, the flight attendant made sure to keep our beverages topped off as needed. It was a wonderful experience"
Cons: "The boarding process for just about any airline is nearly identical. It always seems like it takes longer to board than expected even if, in reality, it's not an unreasonable amount of time. The only think I didn't care for was that overhead storage in the area I was sitting was just about full by the time I was seated which meant that I had to store my carry on a few rows behind where I sat. This meant that during off-boarding I needed to go against the flow of people to get back to my carry on. All in all, it was a minor inconvenience."
Pros: "Our pilot was great. Kept us informed, was pleasant and got us in early. I appreciated the extra information he provided regarding expected turbulance and arrival updates."
Cons: "There wasn't individual entertainment unless i used my own device."
Cons: "We are letting too many people with the flu, travel. This in turn is spreading it to other places and getting too many people sick. We need to control this more. I don’t have an option after spending all this money on if I can stay healthy or not, and that is not ok."
Pros: "I liked arriving safely, although we were an hour and a half late"
Cons: "American switched pilots last minute, so all passengers sat waiting in our cramped seats for about 15 minutes while pilots got situated in the cockpit. Then it was discovered a preflight mechanical check hadn't been done. So we all sat for another HOUR waiting for the mechanics to arrive and do their work. The flight attendants were unpleasant and rude."
Pros: "Great service!"
Pros: "I would like if for my return from Paris to Chicago, Chicago Seattle I would be greeted by the personal and offered to flight first class without extra charge to compensate for the bad experience on my way going in. Thank you"
Cons: "I was told I would be able to choose the seats only 24 hours before the flight by going online. I tried to choose the seats online but could not have access to the site. I then called the number provided to ask for more help, and was told that I could then only choose the seats at the check in time. I was at the airport 2 hours before the flight schedule to book my seat and was told them that I could only choose the seats at the gate. Once I got at the gate I asked the person to please give me a seat at the aisle for medical reasons but after waiting until the boarding process had started I was giving a middle seat. Not only I was treated as a stand by passenger that had not purchased the tickets I was put nt on group 8 and at the moment of boarding the gate personal aggressively grabbed my carry-on bag because they insisted there was no more spaces in the compartment above heads. Once I got inside of airplane I saw many empty compartments available for carry-on luggage. I wish I had not purchased my ticket with Iberia Airlines operated by American Airlines. It was not a good, pleasant experience and do not recommend. I wil certainly avoid in the future and not travel this way another time. Thanks"
Cons: "Our bag was never transferred to the continuing flight. Then it took a week to catch up with us. When we complained to American they just passed the buck to the final carrier, but I think the mistake was theirs."
Cons: "No food or entertainment offered at all - for a 5-1/2 hour flight. Seats uncomfortable. I don't like how it feels like you're nickle and diming us - charging for every little thing, including what seat you sit in."
Pros: "Crew was great, boarding went well, smooth flight."
Cons: "On a 5+ hour flight, they only served soft drinks and a small biscotti. What happened to an actual meal??"
Pros: "Food was good, crew was friendly, cordial which is not good at all on flights by United Airlines, Delta American Airlines and Air Canada. Flight from Miami-Sao Paulo was nice and no too long as when I fly through Toronto by Air Canada or through Chicago by USA airlines."
Cons: "Unable to sleep on the redeye from Seattle to Philly owing to a loud, constant alarm for the entire flight."
Cons: "My screen didn't work and the flashing ads gave me a headache"
Pros: "All the staff were super friendly and warm. The customer service was top notch - beyond beyond amazing. The seats were comfortable. And the cups for our complimentary beverage weren't kids sized! I received a normal cup! The whole experience was a breath of fresh air."
Cons: "There was only one *tiny* negative... baggage. It would have exceeded my expectations if baggage was included instead of an additional fee. But this is wouldn't deter me from flying with American Airlines."
Cons: "We were told the overhead was full, so we had to check our bags, but once we boarded there were complete compartments empty. I suspect they were just trying to depart earlier."
Pros: "Speed from Seattle to Charlotte. We made up for some lost time. Two empty seats beside me because I changed my seat assignment when attendant announced flight was not full."
Cons: "The plane was 2 hours late in arriving for pickup in Seattle. This was difficult for passengers with connections in Charlotte. I was fortunate because CLT was my final destination. Plane carpet was dirty."
Pros: "Crew were friendly"
Cons: "Ac was broke on plane, no wifi or entertainment options, lots and lots of being kept in the dark waiting and waiting after already boarding the plane or landing on the runway"
Pros: "Kind and attentive crew"
Cons: "Was a bit delayed"
Cons: "Your plane needs outlets to charge electronics. Unless your gonna show movies on your flights, ppl need a way to entertain themselves for the flight. If they burn through all their battery power, it's an inconvenience to try to charge it in the airport when they land. All of the outlet Chargers in Chicago, Seattle and Philly were broke as well. The U tied wing was amazing. Your prices are great but to keep ppl from rather paying more just for one or two more luxuries, try fixing this."
Cons: "There was no one at the gate to keep us updated about the flight delay"
Pros: "Entertainment"
Cons: "Too many levels of passengers"
Cons: "My flight was changed 3 times-- always pick a window seat and was changed to aisle seat. The attitude at the ticket counter was "you're lucky to get any seat", flight was overbooked, the boarding process and deplaning were absurd with all the people bringing on way too much carry on luggage !!! It takes almost 30 min to get off the plane!!"
Pros: "It was very inexpensive and on time. And it was much more comfortable than those budget airlines like Spirit, Frontier, etc."
Cons: "The snack choice was unappealing."
Pros: "arrived alive"
Cons: "If you're remotely claustrophobic this is not the flight or aircraft you want to be in. When the flight was booked and paid for I was under the impression that I would have a seat on the plane. As it turned out in order to board the plane I had to pay extra to secure a seat. If this is not a "bait and switch" operation I don't know what would qualify."
Pros: "AA has been good to me--- Gold card a big help."
Cons: "The LAX concourse could at least 2 more coffee shops in addition to Starbucks.The wait was 40 minutes at Starbucks to get a cup of coffee!!! Get on the ball LAX!! We need our caffine in the morning."
Pros: "My window seat"
Cons: "I wasn't able to check in to my flight 24 hours prior to my flight on my AA app and or website. Also wasn't able to check in at kiosk at airport therefore had to wait in line to check in with a clerk which slowed my whole trip mood down."
Pros: "They switched my flight promptly when I missed my connection."
Cons: "I missed my connection for no apparent reasons. When asked for compensation they said there was nothing they could do and cited reasons Regarding the boarding and deboarding of a special needs passenger."
Pros: "It was great!"
Cons: "I would not change a thing the flight was wonderful and the stewardess Virginia great"
Pros: "Seats were fairly comfortable"
Cons: "No in flight movie"
Pros: "The flight crew was helpful"
Cons: "I got stuck in Dallas overnight with no place to stay and no compensation"
Pros: "The flight crew were really good and efficient. The plane was a new 737 and was beautiful and clean when we boarded."
Cons: "The boarding was rough. Very slow. Too many folks with carry ons. Pressure from the gate crew was put on those last in line to hurry to make gate departure time although it was fthe folks on the plane with carry ons that were keeping us from boarding. I paid the money to check a bag but folks with over sized carry on got their bags checked for free at the plane entrancewhen they ran out of room in the cabin. They ran out of room before more than half the plane was boarded."

Everything ok

Cons: "It was a mess from start to finish. Ridiculous lines. Ridiculous covid rules. They have us all shoulder to shoulder in tiny waiting areas then suddenly we get on line to board and have to stand six feet apart and then on the plane we are squashed all together anyway. It’s all so stupid. Not having the ability to get a boarding pass from the online app or printed made me have to wait in a line 300 people long to access the kiosk and then half of them were down. Then another line maybe 500 people long just to be allowed up the escalator to where there is another line to go through exuding checks. Nuts!!! My flight was an hour and I spent three hours online getting to it!!!"
Pros: "All the flights were on time."
Pros: "I had really awful sinus pain on the flight and the crew was very helpful and sympathetic"
Cons: "The entertainment system was pretty lame (DirectTV) and of course the now-typical lack of food and beverage items for domestic flights"
Cons: "This was just so awful! I was so disappointed because I have heard good things about United. The seats I paid extra for were ridiculously small, no leg room at all! Then the plug for earbuds was broken, so I was unable to watch movies or listen to music. I am really dreading the trip back!"
Pros: "Seat was comfortable but little leg room."
Cons: "Difficult to find outlets between seats."
Pros: "The boarding was quick and the flight was on time. The crew was courteous."
Cons: "I selected economy comfort in the kayak app, but when I called about my boarding pass, kayak said they only sell basic economy. What did I buy? UAL only sells a limited selection of overpriced food. There is no music and you have to pay to see the flight map."
Pros: "The flight went very smoothly from start to finish"
Pros: "Poor internet going. No internet or streaming returning."
Cons: "Poor internet going. No internet or streaming returning."
Cons: "Gate crew didn't help much with seating or connecting flights. Staff almost never smiled, and when boarding the plane instead of a, "hello" or "good morning", there were two attendants staring at their phones. They looked up when I greeted first, but seemed put off a touch. They also switched the seating without telling us ahead of time, so my husband and I had to sit in middle seats, apart from each other on our anniversary trip. Very unhelpful and unfriendly when I inquired to change."
Cons: "The plane was delayed in WA DC and the staff did nothing to help with transfers in Addis Ababa and I missed my connection."
Pros: "They staff was friendly and they boarded efficiently."
Cons: "The worst part of the flight was the fact that they have redesigned their planes. They have put the seats even closer together and their new seats are horribly uncomfortable. The seats are made out of a hard molded plastic. There is no give and they don’t form to you back at all. Their comfort level I would rank at a zero! I had thought they may not be bad for a domestic flight as mine was international, however, I also had them for a domestic and they were equally uncomfortable. I will be checking off of United on my next flight as I can not sit in a seat this uncomfortable ever again! Try again United!!! #UnitedSeatsUncomfortable, #HorridSeats,"
Cons: "My friend and I have taken our hiking packs to Alaska, California, Washington, and all along the East coast. Never have we been asked to check our packs. I was mostly surprised, at first. Once I was seated a man in front of me had his hiking pack and two ukuleles in their cases, neither of which could fit under his seat. That's when I became frustrated. O This plane sucks: our knees were slammed into the seat in front of us because the chairs are so close together. No USB plugs. Plane was dirty, scuff marks on the wall and ceiling. There was paper in the pouch that looked like a mouse had chewed on it."
Pros: "I was separated from my 4 year old and 7 year old children as well as our husband. We bought our tickets together but we're out on 4 different rows. I asked flight attendant for help and she was rude. She talked to my husband who was further in the back and came back and told everyone it was ok for my kids to not be with their parents because my husband said it was ok. It was not ok, it was awful. After I started crying someone finally traded spots. But I didn't like that my husband's wishes over Road mine, it was misogynistic and she was a woman, a very condescending women."
Cons: "That our family was separated. That the female flight attendant talked down to me in a misogynistic way"
Pros: "Landing in Dulles"
Cons: "Poor boarding - had to walk steps with luggage, board a bus and wait for 10 mins in hot weather, then had to walk steps to plane with luggage. Plane - no place for cabin baggage and people had stuffed inefficiently their bags; crew did not seem to care Crew - did not care, pointing fingers at people like they do not know English, no sense of pride or commitment in their job; they might as well thrown food at us Food - bad, lucky we were hungry Entertainment screen - not working well Flight was smooth I do not know why Lufthansa partners with United Airlines."
Pros: "The crew were excellent and receptive to needs on the flight."
Cons: "Baggage Claim was a nightmare. I did not receive a baggage ticket when I checked my bag in London. Part of that is my fault. I should have made sure I had one. It took an extra long time to get my bag. Everyone else had left the area from my flight and I approached the counter. The attendant at the counter was rude. She said she couldn't help me unless I had the baggage claim ticket. Which I get that, but it all comes down to how she said it to me. She went over to the carousel and said that my flights bags were still going around and at that time I saw my bag. I said there it is to her and she responds, well you can go get it yourself then. Just completely rude. It all came down to how she responded to me. I was freaking out at the prospect of my bag being lost and she responded as clipped and uncompassionately as possible."
Pros: "The cabin crew themselves were great. The pilots offered my child to go see the cabin and everyone on the actual plane was great."
Cons: "The United employees at check in kiosk were very unorganized and unhelpful. I was traveling internationally with a small child and had two pieces of luggage to check in. Normally you just go to the counter once and they do everything including taking your luggage once they weigh it. Instead, I had to go to the self check in kiosk, then back to the counter to weigh my luggage, take off the one luggage from the scale, weigh the second one, then go back to the self check in kiosk, then was told to take off the second luggage as well, then finally went to a second counter where the lady handwritten my luggage tags and then was told to take both pieces of luggage and put them somewhere else altogether with specific directions on where to put them. This is something normally handled by the actual employees. Also, the check in dude yelled at my kid for putting in his name into the check in kiosk while we were waiting on the check in dude to do all those unorganized activities. He claimed it would break the software if my kid were to enter his name. I have told him that no, the software will not break if my child enters in his name."
Pros: "Rhe food"
Cons: "Custmer Service"
Pros: "Cramped seatting, minimal food or beverage options and we were invited to provide our own entertainment. Pretty typical flight for ten or fifteen years ago. The crew was extremely pleasant. Very surprising and maybe the only saving grace."
Cons: "The airline is clearly trying to maximize profits by squeezing any comfort from the plane while still charging ludicrous amounts. Good for them. That's their free market choice. But do not then be startled that everyone is angry before, during, and after your flights. In the long run that's how you shed customers."
Pros: "Extremely tight fit. Much much smaller than other major airlines . Both flight attendants were rude. Not looking dorward to flying back home with united Option to rent movies is really nice though. Helps the flight go by faster ."
Cons: "Wish the free in flight entertainment was available on the United app for this flight"
Pros: "The first leg of my journey was on time, a little early, even."
Cons: "The second leg was delayed, and the flight crew seemed confused about why. The chairs on the planes were quite uncomfortable, and gave all three of my party some kind of bodily pain."
Pros: "The people were very nice! The entertainment although not easy to access was free. snacks were meh but ok. They did what they could to make us comfortable after flight was delayed 2.5 hours."
Cons: "The flight was delayed for 2.5 hours was out of the control of the crew. They did what they could. But the plane was cramped. Not enough space. Everyone was cramped. We missed our connecting flight they put us up in a hotel and booked alternate flights. We had to stand out in the cold waiting for a shuttle to take us to the hotel. The hotel staff said more than once they were not prepared for all of us and getting us from airport to hotel and in rooms was almost another 2 hours. That gave us 3.5 hours to sleep before we started in the next journey. Of 4 hours from take off to landing in our home city. I had to pay for my baggage to go onto another airline."
Pros: "I had nice people sitting beside me. Not too bumpy."
Cons: "Kind of cramped. Too many screaming babies. A lot of traffic to the restroom. Couldn't put up the arm rest on the window side."
Pros: "The flight was smooth"
Cons: "The air hosts were in friendly and didn't say goodbye. The cabin was improperly pressurized and hurt my ears going up and landing. My ear is still popping."
Pros: "Awesome"
Cons: "Awesome"
Pros: "I learned to stop flying Air Canada or United affiliated partners"
Cons: "Just about everything else"
Pros: "The upgrade to first class, courteous staff, on time arrival, timing of the flight for a red eye. *Note I paid for the upgrade to first class. Totally worth it!"
Pros: "Arriving 30 min earlier Old plane"
Cons: "Old plane, bathrooms are very small and seats were not comfortable"
Pros: "The experience was as good as it could ever be for a 'plane'-jane flight, the crew was really nice! They handled an annoying baby situation really professionally and smiled a lot. Thank you for the in-flight season of Workaholics and House Hunters! I thought that was a cool feature and watched quite a bit to pass the time."
Cons: "But seriously my back is going to be damaged forever from the uncomfortable seating. Even just ones with a decent footrest for someone too short to reach the ground. Thanks from the little people~"
Pros: "Boarding, on time and luggage handling were all smooth with no glitches"
Cons: "Snacks. Really, why bother."
Pros: "My flight was on time both going and coming on my departure. Our arrival was early on both flights. That was wonderful! I liked the comfortable seats and the extra leg room on the plane. Both flights had good crews. I was extremely pleased with United on this trip."
Pros: "Aircraft with old decoration. Could not see a single smile from the crew."
Pros: "Comfortable and enjoyable flight, efficient crew without delays."
Cons: "Poor food - even going for the safe pasta option. Very disappointing & not enjoyable."
Pros: "Nothing at all. Delta is the best I've been with."
Cons: "The attendant were the wrort I've ever. Continue to hit arms s d was very rude to passenger. One didn't close the over head bin while in sever tubulance."
Cons: "People in group 5 don't have a chance to get their carry in bags in the over head storage."
Pros: "My other passengers in First Class. Your crew was also very kind and well mannered."
Cons: "I spent over 150 for an upgrade for a red eye for a flight I already spent over 500. Your crew lacked attention in service and one specific crew member (male) woke me up twice due to the loudness of his voice. Disappointed in the quality for the amount spent."
Pros: "Very friendly and helpful staff."
Cons: "The fact that we had a connecting flight to minot from Denver. Arrived late to Denver because of weather, but my stroller that I had left on the jetway in Seattle was never put on the plane which I didn't know until I got to minot. I was going to wait for it in denver, but I would have missed my flight to minot had I waited 5 more minutes. We arrived to minot only to find out that our 3 suitcases, one stroller and 2 car seats were never in the flight. Awful! And my connecting flight was even delayed an extra 55 min so I don't quite know where my things are."
Pros: "Once I was on the flight it was fine except for the food which was decent"
Cons: "On my outbound flight from IAD to BRU my flight was delayed 3.5 hours because the "plane was late to arrive". Seems like this happens a lot on United flights. The staff at the gate of Dulles airport were extremely rude and difficult to deal with, which made it frustrating to try and figure out my connection situation. I missed my connection from Brussels to Paris and had to buy a train ticket for which I was not reimbursed by United. Then, on the way back from Paris, my flight was delayed 2.5 hours for the same reason. At least this time I had a direct flight. This entire experience makes me think twice about flying United again. I live in DC and it would be just as (in)convenient for me to go to BWI instead of Dulles for international flights, where there seems to be more options outside of flying United."
Cons: "Tight seats - and I'm a small person!"
Pros: "On flight staff are quite courteous and respectful."
Cons: "I'm concerned with the lack of respect that United shows for its passengers time. Cancelled, delayed, boarded and de-boarded all on the same would be flight. I was told via text and found it nearly impossible to speak with a person during the whole thing without physically being at the airport. When I was the staff seemed dismissive of my time and concerns."
Cons: "Everything"
Pros: "Nothing"
Cons: "Being stuck in DC"
Pros: "The seat itself was comfortable but the leg room for my taller companion was a bit tight."
Cons: "It was a 5 hour flight and on the outgoing flight not even a snack was offered. On the return flight a very small bag of spicy pretzel bits was offered. When I went to get on the return flight I had a small sling purse, a small yarn bag (both hung on the same arm) and a bag of food for the lunch they wouldn't serve me. I was told I couldn't get on the flight with 3 bags, even though all 3 would fit under the seat. The free entertainment contained a grey box over part of the image reminding I could pay for more. Was only given a tiny glass of soda, I remember when they would give a can. I will consider another airline in the future."
Pros: "nice crew feeling safe had my luggage very fast (in the airport)"
Cons: "airport was VERY packed! I arrived to the gate 10 minutes before my flight. I asked for window seat (I was not able to make my seat online because of my passport) and they wanted me to pay 10 minutes before the flight for a window seat!! fortunately the plane crew let me sit on window seat since there were lots of empty window seats. The food was not good. The crew was trying so hard to give as less as possible. They were asking "do you want...?" before giving anything. You either need to be awake the whole flight or there is a good chance to miss meal!"
Pros: "The crew was great."
Cons: "A bit less leg room."
Cons: "The worst part was the new seats are the smallest ever. I could not sit without my knees jammed into the seat in front of me, and on both legs, Ithe seats were narrow that the people next to me and I were overlapping shoulders - that was a first. Unless its flights in the future are significantly advantageous, United's losing my business. It's not worth saving a few bucks to me to be so uncomfortable."
Cons: "No TV"
Pros: "Friendly accommodating service"
Cons: "Having my seat arbitrarily changed to a middle seat because of an aircraft change. I selected window seats for all flights when I made my initial reservation. Because I am traveling alone is not a good reason to change my seat. Fortunately everything worked out thanks to very helpful gate agents."
Cons: "Was on a 5 hour flight. Would have been nice to have a tv."
