Cons: "They offered a crummy cookie and literally only orange juice or water."

Pros: "Crew was friendly."
Cons: "seats are to small."

Pros: "Crew onboard was nice and friendly"
Cons: "The plane was late, then it was broken. The delay was a moving target. Finally after an hour a new plane was available. The plane itself was very uncomfortable."

Pros: "I have always flown with Alaska airlines and have always enjoyed my flight. I always will go Alaska if I can. No other airline gives you the same wonderful treatment they give you! Fast check in, courteous team, and they go above and beyond to make your flight as enjoyable as possible. Alaska all the way!"
Cons: "On the shorter flights there isn't anything to do to pass the time. So you hope your seated to a nice person to talk with so you can pass the time. Needs Wi-Fi, movie, or something you can do to pass the time."

Pros: "TWO beverage trips -- how could I not be happy?"

Pros: "This was first Alaska airlines trip and I want to do more! I showed up at the Seattle airport and tried to use one of the many conveniently placed kiosks. I couldn't find my trip, BECAUSE I HAD BOOKED FOR THE WRONG DAY!. This could have been very stressful but an attendant near the (short) line asked me if needed help and immediately redirected me to the VIP line. There, I found another very short line, and smiling, enthusiastic staff. The young woman who helped me got my info, and walked away to get the problem solved with a supervisor. She returned a short time later, my boarding pass in hand, upgraded me to Premium seating and TSA pre check -- without me even asking! On the plane, I mostly slept, but when I woke up I found the attendant had left me my boxes snack which was a mix of nuts and dried fruit in a fancy package. The seats seemed more comfortable than they were in recent trips on United and Southwest. There were plugs everywhere for phone and device charging. There was free wifi(!!). And there were devices available for borrowing. There was even a website for free movie streaming. In a time when most other airlines have sour faced (need to retire!) attendants (Southwest an exception), and EVERYTHING is a la Carte pricing, it is so nice to fly with a company that tries to make passengers happy and comfortable. What a switch!! You"

Cons: "Flight into Seattle delayed, flight out of Seattle to Minneapolis delayed flights out of Minneapolis to Bismarck delayed. Ran from gate F to gate c24 arrived at 10:23 p.m. Slight to the park at 10:25 p.m. and they closed the door on me as I was running up there. Ran across the entire terminal to get there and they would not let me on. Last Flight of the night to Bismarck. Missed my uncle's 90th birthday party. Would not give me food voucher. Delta gate agent told me she would lose her job if she did not close the doors 8 minutes prior. However the Minneapolis flight waited for 15 minutes for people to board that plane. How does that compute? Why would they not wait 3 minutes for me rather than pay the money to put me up in a hotel?"

Pros: "Crew is always friendly"
Cons: "Aircraft broke, had to route me to an additional three stops just to get me home and through the night. Also, still unsure of where my checked baggage is."

Pros: "On time"

Cons: "Actual flights flying on time. What a mess!"

Pros: "Crew was great"

Pros: "Inflight entertainment was the best I’ve seen in coach. Free games, movies, moving map, etc."
Cons: "The seating is too cramped. It has just gone past what is reasonable. Seems too tight on both the knees and elbow room."

Pros: "The crew was amazing"
Cons: "Don’t change my chosen seat that I paid for as I am entering the plane without my knowledge and acceptance"

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 on this flight was great and the flight was quick."
Cons: "The flight was delayed 3+ hours and Delta kept pushing the delay out further without giving any updates as to why it was so delayed, and when I inquired at the Delta desk at the gate the woman was very rude to me as she snipped that it was a mechanical issue."

Pros: "The crew was absolutely amazing!! So kind and helpful! The captain also took a beautiful path around Rainier during a gorgeous sunrise!! The seats were very comfortable and the flight was smooth even though it was a smaller plane (Skywest). I will absolutely fly Skywest again!"

Pros: "That i survived"
Cons: "Cramped no entertainment cofée was nasty"

Cons: "Flight was cancelled"

Pros: "Flight was on a 787! Great plane"
Cons: "Food was mediocre for an international long haul fight, and was served by a completely indifferent staff! My prearranged seat choices were switched to a no recline rows and rebooking after a unnecessarily missed connection became 7 step comedy of errors ,aside from quality aircraft this felt like a budget operation."

Cons: "I dont like that we wasted 3 hours delay in the fiarst fly, makimg us waste more time at los angeles it was a really nightmare"

Pros: "SLC ground gate crew was awesome."

Pros: "Delta is the best airline by far."

Cons: "requirement to wait for seat assignment until at the gate"

Pros: "Very Comfy plane."

Pros: "The crew was great, boarding and exit went smoothly."
Cons: "Seats are tight, not very roomy, I'm 6' tall and my knees were in the seat in front of me. The delta studio entertainment app didn't work, couldn't use the internet at all."

Cons: "Small seats"

Pros: "Good experience overall. Pleasant staff. Movie features were wonderful and helped pass the time."

Pros: "Like the online check in and advanced seat assignment"
Cons: "It's only a 45 min flight so no ptoblems"

Pros: "The crew & my seat"
Cons: "The movie offerings & the snack offerings."

Pros: "They had aircraft flying to my destination. All other airlines were booked for the time and the destination I had in mind."
Cons: "Long Delays, Over Booked Flights, Customer Service is not helpful, Wrong info delivered by Customer Service, No boarding gate info, Luggage was damaged, and I was charged a large premium with no added value. Delta sold me a 1st class flight because of their delays and overbooking their flights. This was because they could not fulfill the ticket I had. This was Delta's solution to their problem caused by them. I still have no idea why the flights were delayed. On top of all this, I overheard a walk-on pilot ask if there was room for him to catch a lift home. The flight attendant responded with "absolutely this flight is not full at all, you can sit right here". Wait I had to pay 200 bucks extra for an overbooked flight and you are having your Delta representatives say different. This was my first and last trip with Delta. I spent 1000 dollars for round trip ticket from Seattle to Spokane WA. No way is that OK or acceptable under any circumstances to treat your customers like this. The best part about all of this is, I have sent feedback and called customer service to talk to a manager to hear the blame put on back on me. Perception is reality Delta. Awful service, awful prices, awful care, awful communication, and awful value for the money."

Cons: "even though I paid for premium economy, the seating was still cramped shoulder to shoulder"

Pros: "I was upgraded to First at the gate. The crew was very professional and friendly. Food mini-minimal, but OK."
Cons: "On this A320 craft, old style, the First class seats are a joke. I had seat 2B. The pitch is apparently less than in the Comfort+ rows. The passengers in 1A and 1B started reclining even before departure, and during the whole flight. For me and my neighbor, with that seat on our chest, it was impossible to reach down to the seat-back pocket, not to mention to the bag stowed under the seat in front. To get out of the seat, I almost could not get my legs through the 5-in. interval between the back of the front seat and the irremovable armrest. I shook the passenger sleeping in 1B rather violently a couple times. The lady in seat 2B apologized, but she had to climb and put her feet on my seat to get out of hers, there was really no other way. Delta needs to address this ridiculous situation of their First Class seats urgently."

Cons: "We didn't try the entertainment."

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: "I was asleep for most of the flight so I missed any food & did not use the internet. I consider an uneventful flight as a great experience :)"
Cons: "At 1 am, SEA TAC had a 20 minute delay for air traffic!"

Cons: "No communication with airlines as far as flight information. The airlines sent me gate change which was incorrect and almost missed my flight"

Cons: "Worst flight experience ever."

Pros: "Nothing great, nothing bad. took off and landed on time."
Cons: "paced seats, nit enough room for carry ons."

Pros: "Gates for connecting were close and even with delay, I made it on time."
Cons: "Flight delay, that made the short connection even shorter"

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: "Atleast 2/3 movies free"
Cons: "That you have to pay for entertainment"

Cons: "Now Sherry in any documentation I received did it say that my flight was operated by United airlines. I waited at ANA check in until within the 2 hour window and went around and asked someone at United who confirmed that they were partners with ANA."

Pros: "How they gave me exit row seats and flifht crew was good"
Cons: "Your check in ticket counter workers in SEA airport.. there was a married couple who was very rude and because i could not get a "prepaid card" but had 25 for my bag the man said "well i guess you are not going" excuse me?! I paid over 200 for my ticket!! Luckily there was a nice polynesian young man who stepped in and helped right away. That couple made my experience HORRIBLE! I do want something done about that! I almost missed a very important event and they looked to be arguing with each other! They need to keep their personal stuff at home! I was so mad.however, the flight crew was awesome!"

Cons: "Delayed because of no crew members"

Pros: "Access to in flight entertainment."
Cons: "Air vent pressure was lacking Cramped quarters but it is expected in economy."

Pros: "Delays 2 hours"
Cons: "Refund"

Pros: "Good flight and good crew."

Pros: "Everything went by smoothly, no problems"

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: "The staff was pleasant and helpful."
Cons: "The flight was late but that was at no fault to the airline."

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: "Nothing. The people were rude the flight was late, the seats were cramped."
Cons: "Everything. I can't say anything about how bad it was."

Pros: "Sitting in first class made the trip a breeze. The seats were extremely comfortable and the snacks were great!"
Cons: "I had an infant with me and mind you he's an amazing traveler but I still seemed to get dirty looks from the flight attendants. The wifi wasn't working and they had to reset everything."

Pros: "Nice leg room courteous attendants"
Cons: "Pay to watch all tv? Not worth the charge"

Pros: "BEFORE BOARDING, THE STAFF WAS SUPER FRIENDLY AND ACCOMMODATING"

Pros: "Quick boarding"

Cons: "Lost my second flight because first one late, got a standby ticket for next flight, but the plane was full, was hungry, no money to spend in airport restaurants, United company should provide at least a breakfast for this inconvenience. Next flight will be with another company for sure."

Pros: "I am 5 foot 6 and my knees hit the seats in front of me. Seat did not recline. Sucked."

Cons: "Delay"

Pros: "The crew was very accommodating."
Cons: "I was seated in the economy section. It was quite uncomfortable for a four hour flight. I'm 5'9" and didn't have enough space to stretch in the 737. I felt bad for the middle seat section because there was no room at all. I had an aisle seat and still didn't have enough room the stretch. There was no food or snacks served but the crew did offer free drinks: oj, tea, water, or soda. if you can upgrade to economy plus it's definitely worth it. Spend the money for it. You will have more leg room for sure."

Cons: "One of two people bumped. I missed a ceremony with my father at the Naval Base due to the delay. We are both military and have had limited time together over the last two years. The $200 voucher does not cover the missed time I had planned with my family."

Pros: "This flight was cancelled. They did a decent job of getting me on to a later flight, but while spending my day at the airport I noticed that almost every flight United had coming or going was delayed. No particularly abnormal weather conditions. Just late flights to and from everywhere."

Cons: "Boarding was a nightmare. Minimal customer service."

Pros: "Sleep"
Cons: "Rude lady serving and no tv options"

Pros: "Beverage service"
Cons: "The seats were so narrow and uncomfortable that it was impossible to enjoy the flight"

Pros: "Efficiency"
Cons: "Turbulence!"

Pros: "Being appeased lead to over a two hour delay. That lead to me miss my connecting flight & missing work later on that day."

Pros: "I flew during the Thanksgiving holiday and all of my flights arrived early."

Pros: "Flight was smooth"
Cons: "Nothing"

Pros: "6 hour flight was a 6 hour flight"
Cons: "1st time going thru the convenience of prioritized seat grouping 1-5. I can understand the theory behind the grouping, but, by time it was my time to board, since I was in group 5, all the overhead luggage bins was filled up. Also, I am a big man that buy my tickets months in advance and choose my seating wisely, months in advance. Just to give it up to a family sitting next to me that wants to sit together. That was my choice in the matter though."

Pros: "The flight attendants were above and beyond. Both of them were very friendly and engaging. If all employees were on the same level as these two flight attendants everybody would enjoy their flying experience better. They are the type of employees that bring customers back."

Pros: "What a great experience. I have flown alaska airlines all my life but this experience with united is a game changer. New planes that are clean. Service was outstanding."

Pros: "The crew was friendly."
Cons: "The flight was delayed hours before the flight, then again, then the second delay was revoked. The flight was from Seattle to DC to Philadelphia, and the layover in DC was too short. A delay that was at first 10-15 minutes, then changed 4 or 5 times until it ended up being a 30 minute delay caused me to miss my next flight because I only had a 50 minute layover in DC. No one could tell us why the flight was delayed in the first place, then I got off my plane, and was told that I had already missed my flight, and given a voucher for a hotel room, and it turned out that the second flight was delayed as well. Then I had to wait an hour for my bag to make it from the plane to baggage claim because they did not put it on the conveyor with the rest of the passengers' luggage, even though I specifiaclly asked them to do so when I got off the plane and got my hotel voucher."

Cons: "Two flights both of which had long delays that were not weather or passenger related. Plane had sardine can seating."

Pros: "The crew was great and friendly."
Cons: "Not a lot of leg room and the guy next to me infiltrated mine as well."

Pros: "Nothing"
Cons: "That my flight was at 5:15am so I got there around 3am and no ONE WAS THERE TO HELP !! It took forever !!"

Pros: "The crew"

Pros: "Everything this was one of the worse companies that I have ever delt with. Both in and out of travel. Customer service was completely rude and inconsiderate and the "supervisor" that hung up on out phone calls 3 times was completely disrespectful with our issue. I will never be traveling with this company again."
Cons: "Everything this was one of the worse companies that I have ever delt with. Both in and out of travel. Customer service was completely rude and inconsiderate and the "supervisor" that hung up on out phone calls 3 times was completely disrespectful with our issue. I will never be traveling with this company again."

Pros: "Cheap and non stop, free chargers"
Cons: "Allowed people to put personal items and carry ons in overhead bins which forced some to check bags. Internet option is useless without Hulu, Netflix support."

Pros: "When it was over."
Cons: "Everything."
