Cons: "I don’t know if this part of your survey or within your purview but I do need to ask or to state my dismay why Alaska or any other airline charge for changing for changing flights to either a earlier or later flight?

Either wearing a jersey or showing a picture with seahawk pride. Very friendly and fun! The views were very beautiful also! Love Alaska airlines and LOVE the seahawks!!"
Pros: "The flight home from Ontario CA was better than the flight there. The seating was pretty cramped . We got pretzels which was great. Service at this airport was extremely kind and cheerful. It made traveling with a disabled mother much less stressful. Thank you!!"
Cons: "Paying to check our bags when others got theirs checked for free by taking them to the gate wasn't fair. Having my disabled mother have to walk from the ticket counter to some wheelchair waiting area rather than bringing the chair to her started it trip off with stress we didn't need. I even asked if they could bring it to her and they said just go over to the station and wait."
Pros: "Prompt, fast, efficient, and courteous."
Pros: "Nothing g"
Cons: "Plane was delayed....which is fine... but when we finally landed, we parked on the tarmac in the rain after 1230am . Had to walk to the airport in the rain and wind. Older people were having trouble walking the distance, I actually went ahead to get a wheelchair for an older lady that I didn't know because there was no one on the tarmac to assist. Very horrible experience and I fly Alaska often. Never have I ever exited the plane on the tarmac in pdx and when I complained to an Alaska worker, she told me it was normal. I fly to PDX once a month and have never exited directly on the tarmac. I will definitely look for any other airline to fly instead of Alaska from now on. I will even fly spirit airlines....that is how much I will never fly Alaska again."
Pros: "The flight itself excellent. Great service The only problem was when we landed there was a traffic jam and could not get to the gate for 20 minutes."
Pros: "Great crew"
Cons: "Food ok"
Pros: "Friendly staff"

Cons: "Nothing really"
Pros: "Very comfortable"
Pros: "Crew was great!"
Pros: "Flight attendants were friendly."
Cons: "Luggage that had to be checked at the gate was not immediately available when we landed."
Pros: "Not one of my good experiences with Delta. Two hours delay in the flight"
Cons: "Information on the flight delay as communication was. at least very poor. Also A 220 was ok but First Class was so so"
Pros: "The food and drinks were so lovely, it felt like I was in first class rather than the cheapest economy seat. Great entertainment selection and comfortable seat that let me sleep well."
Pros: "Amazing crew very good service ."
Cons: "Chose my seat, instead of leaving it to the airline ."
Pros: "There were a few hiccups with the overall flight process, but the crew was very friendly and informed everyone in a timely manner of the situation. There were also good snacks. Also, flexible baggage policy, which was great."
Cons: "The boarding situation is odd and less organized or structured than any of the other airlines I've flown with."
Pros: "Got to Houston on time"
Cons: "WiFi that I paid for on Delta didn't work, flight was delayed at take off due to waiting for restroom supplies; lead flight attendant had a major accent and was difficult to understand. She also stated to keep my mother's walker outside the plane when entering the plane"
Pros: "The crew was amazing"
Cons: "Ran over 2 hours late with no explanation"
Pros: "Crew very efficient. Greeted us with a smile. Movies sere good but hard to hear."
Cons: "Tried to get comfort seats but sold out way ahead. Long trip for not much leg room."
Cons: "Wifi was not working"
Pros: "Good flight in air"
Cons: "Old plane, long delay, sketchy WiFi."
Pros: "Excellent hospitality I asked for a cup of coffee at an odd time, the attendant went out of his way to brew fresh pot and served me, instead of just saying "Sorry sir, we don't have any coffee at this time....""
Cons: "Crew"
Pros: "Friendliness of flight attendants"
Cons: "I wasn't awake long enough to find fault"
Pros: "On time"
Cons: "Small air craft"
Pros: "The crew was good"
Cons: "The flight was incredibly uncomfortable. The Delta team in Houston was not very pleasant."
Cons: "Officiant"
Pros: "Food and service was nice"
Cons: "Very long route to my final destination"
Pros: "Crew was fantastic and very helpful."
Cons: "Not sure who was in charge of loading the plane with food for purchase, but they forgot it all entirely. The crew was kind enough to give extra snacks. Kinda curious how you forgot to load a plane with food for purchase and how did the crew not notice in advance? I would think that is one of their checks of the cabin. Not mention who ever signed off saying they filled the plane with food for purchase lied. Very frustrating not only for the crew but for the passengers."
Pros: "Call back service was best part."
Cons: "Booked ticket through venture card points. This meant that the email address and phone number to contact us in the event of changes was mediocre information. I was informed from Tripit that the flight was delayed, not by Delta. Reservation personnel took logical course of action to find new flight for connection that we could make because of delayed initial flight. I would recommend that they first see if there is an earlier initial flight that the customer could make, then look at finding later connecting flights. We found out about delay 8 hours prior, so we had plenty of time to get to the airport earlier. Total delay required me to take additional day off of work."
Pros: "The entertainment was really good and the service was excellent. Flight attendants were great. Enjoyed my complimentary beverage and on time departure and arrival."
Cons: "It was hard to understand what zone was boarding. Hard to hear and understand made It impossible. And the plane seemed smaller, seats were very close to one another, and it was difficult to get comfortable. I'm not big either."
Cons: "Ac not working at last 30 minutes of flight."
Pros: "I got to fly where I needed to go."
Cons: "The vents above my entire row of seats did not work, meaning there was never any air coming out even when they were fully open. This made for a long, hot, claustrophobic ride. The flight attendants seemed first disbelieving and later unconcerned that no air came out of our vents. I doubt they even reported them as broken after the flight. Delta's new boarding process is absolute chaos. More than half the plane had no seats assigned until 20 minutes before boarding, and the seats were displayed on a screen a good 25 feet away from the gate, meaning people had to constantly walk back and forth between the doorway and the screen. The gate agents were clearly overwhelmed. If this is how Delta is organized now, I won't be flying on them again."
Cons: "I couldn’t watch a movie and I couldn’t fall asleep because the the person in front of me had a light on."
Pros: "Everything"
Pros: "CVG isn't a huge airport, but it has a good amount of things to keep you entertained/well fed."
Cons: "CVG security line isn't terrible, but there seemingly is ALWAYS a decent wait. When a flight is full, like this one, it's never very comfortable – even a short flight."
Cons: "1 hour delay, no explanation, no weather problems, late for my meeting in Houston."
Pros: "The gate agent and cabin crew handled passenger's misery with friendly grace and professionalism. Also, it was an old plane and so the seats, even in coach, were comfortable."
Cons: "Plane was around 45 minutes late in arriving at our Minneapolis gate. Flight was further delayed by something (unspecified) being "frozen." WORST part was that the temperature in the seating area at the gate was horribly cold. Departing passengers at a neighboring gate were bound for Fargo and sat with their parkas on and with parka hoods up. We Houston-bound had packed our coats & boots and were shivering. Then when we finally boarded the crew announced that the plane's water system was broken and so we would have no hot coffee or hot tea or hot anything. No water, also and obviously, in the restroom sink. But sani-wipes were provided in the sink basin."
Pros: "Quick flight, great landing and takeoff."
Cons: "Everything was great today."
Cons: "There was a change in our flight. According to Delta you didn't confirm every leg of our flight and the plane was over booked."

Pros: "Could not use the bathroom"
Cons: "Flight was cancelled and travel delayed by 24 hours."
Pros: "Same"
Cons: "Same"
Pros: "This was a first! The flight attendant (sorry I didn't catch his name) was very attentive and assisted us in first class as needed. He actually addressed us by our name and that made me feel like I was not just a passenger!"
Cons: "Delayed by an hour!"
Cons: "Late taking off, and then unable to get to gate on arrival"
Pros: "Having status. Always on time. They run their schedules like European trains."

Cons: "Lunch time flight. Only food in economy was bags of high carb salty snacks"
Pros: "They did give us the Dane snacks the first class passengers got."
Cons: "Zero additional leg room in this supposed comfort seat. The seat was very narrow and there was absolutely no additional leg room on the flight. I'm tall, so that's what I pay for when I book these flights and none was provided."
Pros: "It was a pretty comfortable flight, with lots of options for entertainment. The food they serve was fairly good and the whole crew was very helpful and kind."
Pros: "Every thing except food!"

Cons: ", Thank goodness we were all considerate of the other.Just need a little more elbow room for a comfortable flight."
Cons: "Delay of 1 h at Philadelphia to Syracuse !!"
Cons: "INTERNET is difficult to figure out in these AA flights"
Pros: "We finally got here."
Cons: "Communication about the delay , which gate we were leaving from, having an entertainment system that worked (they said I could use my device with the app downloaded, but it did not work, I kept getting an error)."
Pros: "Not much crew stayed in back almost the whole 6 1/2 hr flight and seemed not to friendly"
Cons: "It would have been better if they had departed when they said they were going to after a delay. Flight was delayed first 1 hr then two more hours. The airline finally posted that it would depart a 4 PM and we didn't even start boarding until 5PM. Then they tried to rush us on so that everyone was standing on the HOT jetway for 10 min waiting to get on the plane. Plane didn't take off til 5:35 PM. Over all on this trip I had three flights that were delayed. I'll think twice before taking American Air again."
Pros: "The flight was mainly smooth, it was a bit delayed, but made the time up in the air so we got in on time."
Cons: "I still don't know how to connect to the Wi-Fi on board. It's odd, I'm a web developer and that's my job."
Cons: "Instead of taking my one half of one ounce plastic cup half-full of wine, the stewad, allowed me to keep it. I love common sense."
Cons: "4 gate changes, delayed delayed delayed. UGH. Sirens going off at gate no staff around to turn it off or talk to. Lady at counter very upset with pilot. We had a plane at the 2 gate but no flight crew. Next gate no plane but crew. Who organizes this? American airlines has some work to do!"
Cons: "It ridiculous how small the seats and aisles are. It not fun flying any more"
Pros: "Crew was friendly. Clean plane."
Cons: "WiFi wasn’t functioning Boarding and deplaning process is the slowest I’ve ever experienced on any airline. First time flying AA in years. Not sure I would do it again."
Cons: "I missed this connecting flight."
Pros: "Super-friendly crew, really under-booked flight so LOTS of empty seats"
Cons: "“Free” WiFi was really $10, unless you have TMobile"
Cons: "Entertainment is becoming too complicated for us old heads. Food, I still resent having to pay for something that is ed to be included in my fare."

Cons: "Inflight monitor broken"
Pros: "I love it"
Pros: "Friendly staff and helpful"

Cons: "On time"
Pros: "The flight was on time. It was smooth and we had absolutely no problems"

Cons: "80 minute delay"
Pros: "I like the in-flight attendants as they are courteous even though it was late night flight. I cannot complain at all."
Cons: "Gate agent refused to try to put my 9-year-old son to sit next to me. She said "It's full flight" right out of the bat. Well, even if that's the fact of the matter, at least, be kind in responding to customer's inquiry. My son was seated across the isle, same row, but in reality the row was not even straight. And as a little boy, he cannot sleep straight and he has to lean to a stranger's shoulder? Thankfully I got a nice gent who should have sat next to him who were so kind to exchange seat with me. It's all in the attitude.... hopefully my attitude is not as bad :-) But maybe the gate agent was so tired for it was the last flight from ONT, at 1 AM. Bless her heart! Thank you though for your help to get the plane leave on time.!"
Pros: "We arrived safely."
Cons: "I don’t like having to pay for luggage or upgraded seats, WiFi. All money makers. Wish every airline could be like southwest."

Pros: "Nice and clean and seats were comfy"
Cons: "No outlet to charge devices"
Cons: "Seats very narrow. Not enough legroom."
Cons: "I asked for water and juice, they just gave me juice"
Pros: "The flight was smooth."
Cons: "The crew announced we would not receive beverage service without a reason. Also there was very little air coming from the vents, so not to receive a cold beverage on a hot airplane for a 72 minute flight (should've been 52 minutes; however we were delayed on tarmac) is not logical."
Pros: "I slept the entire duration."
Pros: "The pilot did a great job flying. Very smooth."
Cons: "The flight attendants were pretty mean and just overall dissatisfied. Apparently we had community water to share? Everyone gets water from the same bottle?? Too strange."
Cons: "The plane never cooled off for the entire flight"
Cons: "Prices are high and changes are frequent on rates"
Pros: "Service and smooth flight."
Cons: "I bought two exit seats and they were not given to me."
Pros: "Everything was great to me"

Cons: "Food prices a bit high when compared to buying the same thing outside the airport."
Cons: "Two hour delay due to mechanical issue was a showstopper."
Cons: "Cancelled, had to stay in Dallas until next day"
Pros: "The seats were very comfortable"
Cons: "Just wish the bag checked staff would've been more polite"
Pros: "The aircraft was new, clean and had a nice in seat entertainment system."
Cons: "The boarding process is total chaos, self organizing by groups is not as efficient as some airlines. Flight departed over 45 minutes late and arrived late, no concern for any passengers who might be missing close connections."
Pros: "Entertainment only"
Cons: "Cancelled flight and inconvenience was miserable. Unacceptable service from American Airlines, and consistent with others have experienced as well. Will not travel with AA again."
Pros: "Amazing crew and comfortable seats"
Cons: "Food, movies"
Pros: "I eventually got to San Francisco. I missed my flight to Lihue and had to stay in the airport all night."
Cons: "I eventually got to San Francisco. I missed my flight to Lihue and had to stay in the airport all night."
Pros: "Boarding process."
Cons: "Food is not great. Seats are not every comfortable for a 10 hour flight. Need better cushions."
Cons: "Dang the seats are just small in the coach area. Great smooth flight and my bag arrived where it was supposed to be. Cant complain there"
Pros: "Crew was accommodating."
Pros: "The crew was so polite and helpful."
Cons: "Nothing could be improved for this short flight!"
Cons: "The fact that United forces basic economy customers to check carry-on luggage is nothing but a cash grab. Some of the overhead compartments were completely empty yet they force you to pay ?30/ bag. They also gouge you an extra $25 per bag if you bring your carry on to the gate."
Pros: "Just a great flight and service. Super happy for getting home early!"
Pros: "The Rio de Janeiro international airport is very difficult to traverse. However, the airport staff was very helpful in directing me several times to the correct location."
Cons: "United needs a check-in kiosk located between the domestic arrivals section and the international connection hallway just before security. I had to walk to the complete length of the airport and back again, just to check-in. Other airlines, such as Delta, have a kiosk located just before the security entrance. The cabin temperature was absolutely freezing during the flight, and I am usually hot."
Cons: "Food and charging for entertainment"
Pros: "Crew board and also on plane were accommodating and very friendly."
Cons: "Three people in row and all over 200lbs it felt like ever time to get seatbelt Or the horrible placed outlets between seats but under seat and you can not look under seat cause no space in front of you to access and can’t help but to rub against person in next too you. So had to apologize and explain what was trying to do before I tried. I try not to fly this airline or other large carries for"
Pros: "Accurate information"
Cons: "Nothing"
Pros: "The direct flight was really nice."
Cons: "That entertainment had an extra cost."
Cons: "Flight was cancelled on our way back home from Gudalajara, was speaking to a representative for almost 2 hours to get me on the next flight the flight representative forgot to put me on hold and told everyone how rude i was, i was not rude i was just trying to get home. The representative couldn’t help me so i asked to be transferred to a manager, after 2 hours i was transferred and the manager hung the phone up. Long story short i called back spoke to another manager Yana and she was the rudest lady ever! She basically told me for waiting to long i will have to be placed on a flight 2 days after my cancellation flight. I started to cry because i needed to be home and she basically did not care so i took the date. Never again and i will warn everyone about this airline and their customer service!"
Pros: "The marvel of flying. Hurling through the air in a metal tubeZ amazing. We got there safe and on time. That’s what I liked about United. Oh and there was a CSR that was helpful in changing to an earlier flight."
Cons: "Plane was dirty. Bathroom disgusting. Crew just trying to get through the work day. Seats too close and REAL uncomfortable. Like sitting on a plastic frame with a piece of fake leather over it. Entertainment was awful. Oh wait, non existent since it was an “out of country” flight so there was no access to movies (that you had to PAY for). Otherwise you got to watch Matthew Perry in some taxi game show over and over and over and over on a monitor in your face that couldn’t be shut off. United is my last choice in airlines. But we did get to the destination safe and on time."
Cons: "The plan had to be maintained with no option for getting to my final destination on time."
Pros: "United is an OK airline, but their planes are old and not comfortable, entertainment is inexistent since it has old and bad screens and everything is paid, better to have your own tablet."
Cons: "Seats aren't comfortable, airplanes too old, food is bad, crew members don't have the service as Asian or Middle east airlines."
Pros: "Flight was short so I I did not get too involved with crew, men had smiles and hellos not so with females. Maybe they get too much stuff from other passengers but I was a little surprised by it. I haven't flown in quite a while but I don't remember that bad attitude. Drink service was good with snacks."
Cons: "There was no food, entertainment and seats are not that comfortable for a person with back problems. Female flight attendants are not so much in the friendly skies"
Pros: "Crew was great and helpful!"
Cons: "Not enough options for people with celiac."
Pros: "I slept the whole way."
Cons: "n/a"
Cons: "taxi time longer than fly time"
Pros: "The flight was short."
Cons: "Felt cramped and"
Cons: "There was no in-flight entertainment option on this leg of my journey, which makes a four-hour flight seem long."
Cons: "No beverage offered during the entire flight. Plane was on the runway for about 40 min prior to take-off. What a waste of time!"
Cons: "My flight was canceled because of the hurricane in Houston which was completely understandable. Trying to rebook a flight was one of the worst experiences I've had on the phone. Over 2 hours on hold only for United to tell me to call back inside 24 hours of my requested departure (which was about 12 hours outside of the time I called). Bad customer service all around, both Kayak and United."
Pros: "Nothing"
Cons: "My flight was delayed making me miss my connecting flight and was not compensated for anything only a sorry"
Pros: "i was rebooked and am still on my way"
Cons: "i was delayed in ONT, making my flight an almost 24 hour trip from vONT to my destination. not fun had to reschedule car rental. luckily, they did not charge extra"

Cons: "Average"
Pros: "I get a refund"
Cons: "Getting to the airport and being told you are not in the system to get your tickets when you give all the information to the counter after you paid in advance and have to take the grey hound instead so I am pissed off at this air line and going to let my friends and family know how I was treated there"
Pros: "The flight was comfortable."
Cons: "N/A"
Pros: "Direct flight to Houston"
Cons: "Staff boarding did not care travelled with my diabetic mom going home to Houston they could not be bothered to seat us together response was " ash your fellow passengers to swap with you" how aweful"

Pros: "Great smooth flight. Flight attendants very nice."
Pros: "Flight Attendants were nice."
Cons: "The flight was expensive and they wouldn't let us or anyone place carry ons in the over head bin. It was an expensive ticket and didn't include checked bags ($25 more). Carry-ons wound up being "stowed". It would have been nice to know before I bought the tickets that I needed a smaller carry on."
Pros: "It was good for most"
Cons: "Was good"
Cons: "I received somewhat bad service at every point of contact with United. My flight was canceled in Houston, so I forced to stay overnight. I asked the rep at the customer service station if United pays for a hotel room if our flight gets canceled, I was told no. There were several canceled flights, do all the hotels were booked in the area. It was up to me to call every hotel in a 10 mile radius at midnight to find a room. I had to come out of pocket 150 dollars for the room and I missed work the following day due to my canceled flight. I was forced to stay in a hotel room with none of my clean clothes, no toiletries. I was told by a united rep, "we get off at midnight so you won't be able to get your suitcase today". All in all, it was one of the worst flying experiences I have ever had. I would like some one to call or email me."
Cons: "I had asked for help for when we landed in Houston to get to my conecting flight. The attendant was nice enought to arrange it, but when we landed and I introduced myself to the person with the wheelchair, he made me feel bad enough to walk to my conecting flight.

Cons: "I arrived to the airport at 9:30am, I waited in the check in line for over an hour and 30 minutes. Until the time was 11:10. That's when they started pulling people that were flying to LA(flight 918) out of the line to check them in so they could board. I didn't like the fact that once we boarded the plane, we sat for 40 minutes. Not moving at all. The entire flight was bumpy, although not the pilots fault. Very uncomfortable. We were skipped for no reason when the flight crew was handing out the customs paper. Then we were also skipped when they were handing out the drinks and food(which isn't free anymore). Not even water was free"
