Maybe a little tiny snack

I booked my flight business class trip to Thailand with kayak, but my final leg from Seattle to Denver was not processed correctly though Kayak (according to Qatar Airways). As such my first class ticket for a three hour flight turned into a 9 hour flight from Seattle Anchorage to Denver economy middle seat and no one is willing to answer what happened or take responsibility!!

Pros: "Seat comfy staff friendly"
Cons: "None"
Pros: "Crew was good."
Cons: "Uncomfortable seating"
Pros: "The male steward was very nice"
Cons: "Flight was delayed on tarmac for 2 hours better communication"
Pros: "Friendly crew. Great movie selection through gogo inflight entertainment!"
Pros: "Aircraft was clean and comfortable. Crew was efficient and friendly. The whole experience was excellent!"
Cons: "There was lots of entertainment available but plain old music was not an option. What if I don't want to watch a movie or TV, just listen to music!"
Cons: "Seat cushions are too thin."
Pros: "Great on time too"
Cons: "Very happy"
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: "The flight attendants were friendly and professional and took time for a little personal conversation."
Cons: "Employees who just don't care"

Pros: "I was made to feel comfortable right from Bangalore by the checkin people, because I indicated to them that I had a fear of missing my connecting flight from Seattle to Denver. My connection to Denver went smoothly,however the flight attendants on Air Alaska need to be more courteous and friendly."
Cons: "Did not like the flight attendants but the pilot made up for the humour that was lacking. Never seen a pilot interacting the way this one did."
Pros: "Glad I discovered Alaska Airlines!"

Cons: "Cramped seating"
Pros: "good"
Pros: "Their staff was awesome as usual no issues with the flight ."
Cons: "So many bags that were suppose to go under the seat infront of you that weren't. So that those of us that boarded last had to wait while stewarts removed small carry ons. So that our one carry on that fit in the box but not under the seat could be stowed. It would be nice if the smalls bags that are to be stowed under the seat were. The family next to me had 9 bags in the over head. There were two adults and two children 3 and 4."
Pros: "Roomy seats and plenty of legroom"
Cons: "The whole experience of making a connection in SEA detracts from the travel experience. There is little room for passengers to sit while waiting for their Alaska flight. It causes masses of people in the walkways, and makes it hard to walk through, or get out of the way for others. It may not be the airline's fault, but as I said, it detracted. I don't remember SEA being that overcrowded on previous trips. Our incoming flight was delayed due to weather. Again, not the airline's fault, but we were told we'd be able to make up the time and be on time in DEN. We were still late."
Pros: "Went very well. Not stupid"

We flew First Class to LA from Denver on the Delta-branded contract airline - Sky West. On the way back, we flew First Class on a Delta Airlines owned jet, and the experience was so much better. The flights should have been comparable; but unfortunately cost-cutting by Sky West was evident.

Pros: "The staff at Delta are always friendly and helpful and they were able to squeeze me onto a very full flight."
Cons: "The main economy seats were far too narrow."
Pros: "I always have a consistently good experience on Delta. Everything was great."
Cons: "It was a Great flight. I always enjoy flying Delta"
Cons: "Not really an experienced flyer. Overall the flight seemed good. No issues with airline or airport. Just don’t understand self-important people that feel compelled to push the overhead storage limits with their bags."
Cons: "Flight was delayed and completely packed so our family could not get seats together"
Pros: "Love the fact that the head rests move to support your head better."
Pros: "The male crew member was excellent. He was responsive and speedy with trying to find a solution. He gave me a few flyer miles for my trouble and was empathetic, which is rare."
Cons: "The tv/monitor didn’t work so there wasn’t any entertainment for the majority of the flight."
Cons: "No meal option and my video screen volume did not work"
Pros: "Boarding was easy."
Cons: "I am 6' 1" tall and weigh 220, so not out of the ordinary and I felt like I was stuffed into a sardine can."
Pros: "Entertainment"
Cons: "Boarding at JFK.Always messy"
Pros: "Boarding was quick"
Cons: "No entertainment, plane was small"
Pros: "Good entertainment selection and great crew"
Cons: "Seats are more uncomfortable relative to other airlines"
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: "Early and middle seat was open!"
Cons: "Coffee tasted like fish. :("
Pros: "Entertainment choices were excellent, many new movies available, so I was able to see movies is been meaning to watch. There were drinks available."
Cons: "The air vents barely trickle out any air anymore. No relief to be had. Airline crews say hi and goodbye but that doesn't make them friendly."
Pros: "The crew on the airplane was great. We had 2.5 hours turbulences but the crew started to give out drinks as soon they got the ok from the pilot"
Cons: "We went in LGA to the Baggage drop off and the employee there was super rude. On the flight to New York with Delta we had to check our carry ons at the gate because it wasn't enough room for bags in the airplane.so we asked when we checked our one suitcase if we can/should check our carry ons to avoid having to do it at the gate. The delta employee told me sure no problem. He checks in my one suitcase I purchased gives me the tracking paper and says ok have a good flight. I asked him so what is with our carry ons and he told us that that would cost 25$ and we can't check those in at the drop off?!?We ended up taking the carry ons with to the gate and then off course there wasn't enough room on the airplane that we had to check it in. And surprise it was free?? We had never issues with Lufthansa, icelandair etc. with checking our bags at drop off to not needing to carry it around and than still end up to check it at the airplane. Every airline has been more than happy that we volunteer to check our bags that they don't have the trouble at the gate."
Pros: "We boarded close to on time, no hassles. Allowed my husband and me (retired military) to board early, thank you."
Cons: "LAX security is awful. We never left the airport (arrived LAX from Sydney AU) yet were forced thru security again. Had to remove shoes, was scanned and "frisked" by TSA to get to Denver. To go to Australia, Denver TSA waived the removal of shoes, skipped the scan for the metal detector and no one touched me, ditto for LAX on the trip to Sydney. Where's the uniformity or standards for TSA?? Why did I have to be subjected to this garbage on the way home?? This is why I despise flying. It makes no sense to me. This ruined what was a great vacation."
Cons: "Very little leg room."
Pros: "JFK to Denver the flight Attendants were once again great. Lots of entertainment choices again. The usual rough air coming into DIA."
Cons: "From JFK to Denver the seats were to close for leg room by an inch or two. The temperature was hot most of the flight."
Pros: "Love the built in tv’s with free entertainment."
Cons: "The plane got delayed on the runway and the shut the engines off so the plane got super hot, but even after we got up in the air it never cooled down. Normally I’m freezing on flights, but I just sat sweating this whole flight. It was terrible."
Pros: "Delta....ticket counter...gate agents....flight attendants....pilots...amazing customer service with a smile! Very attentive and everyone thanked me ( and other passengers as well for flying with Delta."
Cons: "Nothing negative to say!"
Pros: "I usually have had great experiences with Delta. The meal selection was limited. By the time they made it up to my seat they had run out of what we wanted. Also, the entertainment system at my seat and my husbands wasn’t working well. One of the bathrooms had a cabinets Tvst oliiiooooiiooooioiooiiiooiio"
Pros: "The staff really helped me out getting on standby so that I didn't have to wait for a 9 hour layover. Overall great experience and great staff."
Pros: "Everything was perfect !! Staff friendly"
Pros: "Excellent piloting and cabin crew."
Pros: "It got me home, eventually."
Cons: "Poor communication, a 6 hour delay followed by a 7 hour layover (during which we had to sleep on an airport floor because Delta couldn't offer us any hotel vouchers). Gate agents disappeared after 7pm becuase they were due to be done with their shifts when our flight was originally supposed to leave at 6 pm. It felt like we were trapped in the movie The Terminal. Oh! And our bag was misrouted, because that was just how things went those 2 days. All in all a 6 hour trip turned into 18 hours. I could have driven home in that amount of time!"
Cons: "Check in lines were crazy long"
Cons: "My daughter was stuck in SLC for 5 hours because there 1 cancelled flight and 1 delayed flight. It was very upsetting not knowing when she going to arrive in Denver."
Pros: "First leg from San Diego was excellent."
Cons: "Arriving in SLC discovered out flight to Denver was CANCELLED! Had to reschedule to the next day. Not fun!"
Pros: "App is good and convenient to use."
Cons: "The app went down just as we were getting ready to board and luckily i had a printed pass and it took some extra time to check in."
Pros: "really helpful and friendly service and nice seats."
Cons: "We left late, it was delayed then maintenance issues. Twice. Seating was very tight and uncomfortable, no movies or entertainment at all. U.S. flights are the worst. Even on short flights with aeromexico outside the U.S. you get movies and food. Zero stars for comfort, food and entertainment."
Pros: "free texting and entertainment!"
Cons: "our flight was delayed half an hour."
Cons: "I don't like that I already completed this survey several days ago and have been receiving reminders to do so. I guess you don't have a good system in place for knowing who has and has not completed your surveys. That's too bad."
Pros: "The boarding process in Atlanta was as smooth as could be expected given that it was a full flight. I appreciated the gate announcer's suggestions to everyone about how to ease the overhead baggage crunch."
Cons: "Economy is very tight quarters."
Pros: "The plane, crew was clean, newer and had TV's in the backrests. Remember to bring headphones! Seats are tight, but the crew was friendly and may the flight experience positive."
Pros: "Friendliness of staff. Second flight was a newer plane - sweet!"
Cons: "For a long flight perhaps a little more in the snack department."
Pros: "Crew was all very nice"
Cons: "Flying is always uncomfortable"
Cons: "Excellent service excellent pilot"
Pros: "Flights were both on time and boarded quickly. Crew was wonderful!"
Pros: "Free in flight entertainment"
Cons: "One of my bags went to Santa Fe"
Pros: "Entertainment"
Cons: "This is my third flight this year with Delta and every time we wait for the "crew" to get off from another flight. And as soon as they get there we can board. It's getting very annoying. Fix it."
Cons: "I'm tired of Delta making it IMPOSSIBLE to experience benefits of my loyalty. I flew literally AROUND the world in the past 6 months and it STILL doesn't qualify me for anything more than Silver elite? Seriously? When you use a voucher because of their error to lower your ticket price, but still pay cash for it, why does that then automatically exclude you from upgrades? Poor customer loyalty, in fact, non-existent these days."
Pros: "Early arrival. And service"
Cons: "I was assigned very last seat and there is no reclining option."
Cons: "long wait and delayed flight"
Pros: "WiFi, good flight attendants"
Cons: "Would like to see Direct TV along with Delta Suite so can watch live TV"
Pros: "Attendants and entertainment"
Cons: "Delays for no explained reason"
Pros: "plane had individual movies for free with each seat!"
Pros: "Yes"
Pros: "Crew on both our flights were very nice and accommodating."
Pros: "United delays"
Pros: "Nothing"
Cons: "Arriving on time to make my connection!!!!!!"
Pros: "Plane wasn’t full, crew was great"
Cons: "They could have better food options for a 7 hours flight."
Pros: "Nice crew, good take off and landing"
Cons: "We were an hr late taking off."
Pros: "Good leg room"
Cons: "Seats are narrow. Not much shoulder space"
Pros: "Nothing, worst experience I’ve ever had traveling. Up for nearly 2 days and with no help from the local airport staff."
Cons: "Everything, no customer service whatsoever"
Pros: "Everybody was wonderful. All the staff were friendly and the flight was great."
Cons: "I volunteered to gate check my instruments (which I NEVER do because it’s not my hobby, it’s my livelihood). When I did, I made very clear that I’ll ONLY do it if it’s handed to me at the gate when I arrive. It CANNOT go into baggage claim because it’s 2 $3000, left handed, vintage Paul McCartney basses packed in one bag. The gentleman assured me that I’d have it handed to me upon arrival. It isn’t designed to go through the rough handling of people I’ve never met or trusted. So I got to Denver and waited at the gate until someone told me, “oh no that’s gonna be down in baggage claim” Needless to say, I’m scared to death and I don’t even know where $6000 worth of instruments of mine, is right now. I wish people would communicate when they promise things."
Pros: "Seats were comfortable, we were in first class. United provided a good selection of recent movies."
Cons: "United stewardesses have little to no interest in their duties. Questions were clearly an annoyance to them. The leg of flight from Denver to Des Moines was very uncomfortable, seats much to tigh, no leg room. Gate staff in Denver were exceptional. United needs to revisit their time for loading. We preloaded, I had a broken leg, I was traveling with a special needs woman. We just reached our seats when other passengers were prodding us to sit so they could board no time to settle. Not impressed"
Cons: "Lost bags and every time I called to find out where they were I would get a different story. I was told it would be on the next flight for the next 5 flights."
Pros: "The flight attendants were so nice, and although our flight was delayed and hour and fifteen minutes and our layover was an hour and fifteen minutes, we were able to make our connection! Since our connection to Portland in Denver was the last flight of the night, they were able to hold it for us. This was wonderful because there weren’t many flights out that weren’t booked solid for the next day. The attendants on this flight were great about updating us with information for the connections and telling us when we would land in Denver."
Cons: "The plane was delayed over an hour for cleaning. It was frustrating to say the least."
Pros: "The flight was on time"
Cons: "This was a smaller plane (4 seats across). Knowing this, they didn't bring enough luggage carts, so they only brought some of the luggage to the baggage claim and didn't tell us this. 5-6 of us waited and waited and finally asked someone who told us that they had to go back to the plane to get the rest of the luggage. Those of us still waiting got to wait another half hour for our luggage. Talk all they want, United just can't seem to get it right. PS: those of us who had to wait were the ones who got to the San Antonio airport the earliest and thus our luggage was on the plane first."
Cons: "Seats to small. But I am 6'3"" and my son traveling with me is 6'5"."
Pros: "The leg from Denver to vegas was awesome"
Cons: "The first leg didn't have any snacks and a cold continental breakfast. American and Delta's breakfast is much nicer. But worth the price for that portion of the leg."
Pros: "Nothing"
Cons: "The plane was freezing. I needed to put on socks--really wished I had packed wool ones. The seats were cramped and mine did not recline."
Pros: "free movies on the flight with the united app"
Cons: "The flight attendant was late delaying boarding 20 minutes. Once they started, people were lining up to board. This is a normal behavior however, there employee decided to stop boarding because she said people were crowding. she stop boarding for another 20 minutes. Now, this was a large flight and there wasn't enough room for everyone to stand off to the side. She was rude and there was no reason for this especially when the flight attendant was already late. The plane was delayed 45 minutes due to this"
Pros: "I was sat in an exit seat."
Cons: "The lady in the seat next to me was so overweight that I couldn't sit comfortably for the entire flight - I had to lean out and it hurt my back!"
Pros: "Nothing I won't be flying united again!"
Cons: "The lady at the gate when boarding was not friendly and was not willing to help us get seats together. I was traveling with my mother, husband and two infant children. And it was like pulling teeth to get any information out of her. She did not even tell us we could board early to get situated on plane! I also called earlier that morning and spoke with a man on he phone at united who told me he put us all in the same row. That was a lie bc when we checked in at the gate to get our seats the lady said no one was sitting next to each other! That lady was rude and short tempered! Awful experience will never fly again!!"
Pros: "Onboard service"
Cons: "The default on the browser defaulted to April 9 when I was actually booking the ticket for April 2. So I had to forfeit the $317 ticket. I use kayak a lot - can anything be down ?"
Pros: "Everything went fine and they sorted out a spot for me to sit even though the flight was overbooked"
Pros: "Food was edible, nothing special"
Cons: "Boarding was very slow, as was cabin staff. Not very attentive. Made a big deal about letting passengers with connections off first, although we arrived. We waited, as requested. Finally got up,after realizing everyone in the 20'rows behind us was gone."
Pros: "I got to where I was going."
Cons: "Leg room"
Pros: "The extreme help of the boarding agent trying to ensure that, even though we we're leaving Great Falls late, I was able to get to my connecting flight"
Cons: "It seemed that the flight from Denver to Great Falls and the return flight to Denver was very late both times. Once due to mechanical issues and not sure of the reason from Great Falls back to Denver"
Cons: "My friends dad passed away and was unable to get money back to go to his funeral. Plane was a small express plane which was never mentioned. Had to check bag because overhead bins were too small. No wifi. Dad and Kid took my assigned seat."
Cons: "Flight was delayed to 4 hours now I'm rushing all over to get to my connecting flights"
Pros: "Small airport, comfortable seating, polite crew"
Cons: "Snack wasn't my style"
Cons: "Unable to pre-check online. Unable to check at the check in machines--had to go up and check in at the counter, long wait because there was only one clerk. We were then given a ticket just to get through security and had to check in a second time when we get to the gate for seat assignment, which is ridiculous. Why couldn't that be done at the 1st check-in? The clerk told me she will call me when she has the seat assignment/ boarding ticket but she never did and I had to go back up to ask for them when it was getting close to boarding time. At the last moment minutes, volunteers could check in their carry on for free....It would have been nice (and less hassle) to have that option at the 1st check-in."
Pros: "Quick and easy boarding, friendly staff, On time/early to arrival"
Cons: "Not a lot of space for passengers- even someone small like me at 5'2 and 120 lbs. Flight was also a bit turbulent"
Pros: "Nothing"
Cons: "I'm usually a patient person, but my flight was supposed to leave at 525am and didn't leave until 730. This was the first flight in the morning. We boarded, waiting 30 minutes on the plane, they told us to get off because there were computer issues. Why wasn't that checked before everybody was boarded? Once we got on the plane we had to wait another 30 minutes for the crew to get someone's luggage from under the plane. Why wasn't that done while the computer was getting fixed? I didn't get to Denver until 1040am missed my flight and didn't get to get on my connection until 500pm. In the meantime I called to get on a different flight at 1, but the guy on the phone didn't actually book me a seat. The gate people weren't very nice."
Cons: "The flight attendants were disrespectful to not only me but to other passengers. They were not attentive! The plane was dirty."
Pros: "Boarding was very fast and efficient. Seats were as expected on an airplane. The flight was only 45 minutes so there was no entertainment or food to really be able to rate them on it."
Cons: "The one flight attendant spoke super fast so it was a little hard to hear her clearly."
Cons: "A la ahora de irnos hubo muchos contratiempo por el tiempo pero por el vuelo después que nos fuimos fue excelente"
Cons: "I didn't like every fight being cancelled, every gate being moved, and my luggage being lost."
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: "Crew were fine."
Cons: "Seats are narrower and make for a lot of discomfort when stuck in the middle seat. I do not like other stranger's bodies touching mine. That is just wrong."
Pros: "The staff was very helpful"
Cons: "Turbulence was horrid. Had to re route the landing causing me to miss my connecting flight. united had no other options for 23 hours. Therefore I chose to return to my starting destination. I still had to spend the night at the airport, and missed a 10 hour day of work due to no other flight options. All I received was a verbal apology. Glad I paid for a flight to a one night stay at Denver airport and back."
Cons: "One strange thing happened on my United airlines flight. The crew announced before we boarded that there wasn't enough overhead space for rolling bags and encouraged us to check them in. Upon boarding they announced that all overhead space in the back was full. I sat in the back and noticed that the crew closed the overhead compartments even though they were mostly empty. Another passenger opened an empty one and the crew came over and closed it right away, though many people were still boarding. What's going on?"
Cons: "The airplane was freezing, and I'm 23 years old and very used to flying."
Cons: "Additional fees for extra space were 1/3 the cost of my flight"
Cons: "My flight was scheduled to leave at 4:51 pm. I arrived at the airport 2 and a half hours before my flight was to leave and I read the departure board to see that the flight was delayed due to maintenance. Then I saw that it was delayed again because we were waiting for a flight coming in from the Bahamas. Well my flight didn't take off until about 7:30 pm. I arrived in Denver around 10:00 pm which made me miss my shuttle to the Springs. I am a diabetic and was in need of my medication so I needed to get home. I spent extra money to take a bus to downtown Denver and a grayhound bus to the springs and a cab to my home. So my trip cost my an extra $55.00 dollars I didn't have. I have always taken United but after this experience, I will never again take United."
Pros: "The crew is AMAZING!!! Personal, professionals, they go above and beyond my personal standard of customer service. Very comfortable atmosphere. Not to be mistaken with the uncomfortable seats. I like to think United doesn't overlook the work ethic their employees represent the company with on a day to day basis."
Cons: "I travel for work from Grand Junction, Colorado to Dickinson, North Dakota every 4 to 6 weeks. I always fly United. On one occasion I met family in Colorado Springs, so I bought a round trip ticket from Dickinson to Colorado Springs. I missed the second half of my round trip flight from Colorado Springs to Dickinson. I had to pay my own cab fare from Colorado Springs to Denver to catch my flight, because your plane, that i paid for a flight on, had mechanical issues and didn't make it to Colorado Springs. Second, my flight in Denver was cancelled 3 times and almost a fourth. I all but got down on my knees and begged to catch the fourth flight they tried to cancel. Third, I didn't even get to fly into Dickinson. So instead of somebody coming and picking me up in Dickinson which is a 30-minute drive from where I work, somebody had to drive 3 hours to Williston where you guys ended up getting me. Which cost me 3 hours of gas money to get picked up, instead of 30 min of gas money. I didn't get either of the flights back to North Dakota that I paid for. I've asked for the reasonable request that I be refunded 50% of the cost of the airfare and the $235 it cost for cab fare. When I contacted United about this I got the runaround from everybody. At this point I've pretty much accepted the loss, and the financial hit. I'll continue to fly United only because it's pretty much my only option. Just make sure you keep the crew around. They're great. I'd hate for the experience to go from unsatisfying, to miserable."
Pros: "they gave us the whole can to drink on the flight for drinks"
Cons: "the stupid old white man at baggage check in in New YOrk who was EXTREMELY rude and made me HATE flying with UNited"
Pros: "Nothing"
Cons: "Everything. They didn't schedule aircrew causing our connection to be missed. Had to stay in Denver and pay for a $60 cab to take us back to airport after they scheduled us in a hotel clear across town with no shuttle service to even get us back to our rescheduled flight. Their customer service stations Are apparently useless and can't do anything to actually assist anyone."
Cons: "Had to pay to check both of bags."
Pros: "My flight started off with getting to the airport only to find my flight had been canceled in the morning and rescheduled at an earlier time while I was at work. I don't check my phone or email while at work. Fortunately, your staff was quickly able to put me on a flight that left an hour and a half after my original flight, but would put me on a connecting flight with American Airlines in Chicago. The AA flight had engine trouble so it turned around and we borded another plane after we landed. The original flight would have had me to my destination by 9:30 pm. Instead I arrived at 1:08 am the next day. I am frustrated that my flight was canceled so close to my departure. It was a great inconvenience to those picking me up at the airport. It added to my stress. It made it much less likely that I will fly United again. Maybe you had good reason to cancel my flight at such short notice, but it severely tainted my experience and opinion of United and American Airlines which had been fairly positive until now."
Cons: "The inconsideration for my schedule. The last minute change."
Pros: "Punctual flight, lack of major issues. Friendly staff helps on a long flight. Handled minor issues in the cabin well."
Cons: "Boarding the 747 was a bit disorganized, using doors on both sides of the gate desk led to confusion."
Pros: "Not only do I get the best price. The fact that you told me what carousel to get my bag from was new to me. I alway check kyak first but now I love u guys. I know my travel site and its kayak"
Cons: "My flight was many hours delayed due to bad weather in Denver. Then my flight from Denver to LAX was eventually cancelled so I took a direct flight from Phl to LAX on American. That flight was fine."
