I couldn't believe how comfortable and spacious the seats are in coach! I am also so pleased that Alaska Airlines is plastic free for their in-flight beverage service.

The flight was oversold and it was a bit nervewracking wondering if I would get on the flight. I never know with these kinds of things. I upgraded to a premium seat which was great legroom and early on/offboarding but it was still shoulder-to-shoulder in the row. It was uncomfortable and took contorting though we were all civil about it. Overall, it was a comfortable flight - crew was outstanding/attentive from check-in to off-boarding. I didn't have the food, so rated it just "good".

Pros: "Nice quiet flight"
Cons: "Crew member attitude specifically regarding passengers in the emergency rows"
Pros: "Flight crew was nice"
Cons: "They were careless with our suitcases. When we got to Vancouver, we were missing wheels on our suitcases. 2 wheels on my husband's and 1 on mine. It made it horrible to pull the suitcases."
Pros: "Crew was great, the flight was good. Food is good but expensive."
Cons: "Free or inexpensive food options would be nice. I also prefer when the screens are in the back of the seat and I don't have to stream on my phone or pay high prices to use data."
Pros: "Crew were very attentive and hospitable to the crew. I have been flying ASIANA many times and enjoy the flight as well."
Pros: "Crew was friendly"
Cons: "Tray tables very dirty, flight overbooked, hard to find gate agents"
Pros: "Crew is always amazing and friendly on Alaska."
Cons: "There were no movie devices for some reason on the flight"
Pros: "Nothing"
Cons: "What have been nice if I was told that seat availability was nonexistent. I tried checking in each day without any information such as give it up you suck and you’re going to get the worst seed no better how much you try to avoid it…"
Pros: "The flight was great and the process from boarding to take off was wonderful. This was also a rescheduled flight after my other flight was cancelled."
Cons: "The seats cushions. They weren't the best. That's all."
Pros: "Boarding process need to be improved. Seat assignment is horrible"
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: "I always appreciate in-flight television even on short flights."
Cons: "Very tight seating."
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."
Pros: "It felt like it was over before it even started!"
Cons: "The wifi wasn't strong enough to download the app to watch movies on the plane."
Cons: "No drink or snack service. No trash pick up. No option to purchase or rent headphones"
Pros: "very little"
Cons: "Could they make sears smaller? The plane was really old too."
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"
Pros: "Accident on way to airport, so I showed up to check bags 45 minutes before flight time. They said they couldn't get the bag to the plane..in 45 minutes? So, they put on the next flight... 6 hours later. Said I could fly without the bag... uh, no thanks. They would not look for alternatives without charging me more. Flight attendants were crabby, otherwise everything was fine. I flew British Airways a few months ago. Night and day. Seriously. Delta does not even approach having good service. There was no comparison to British Air--- Delta is not in the same league."
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 efficient and pleasant making for a good experience."
Cons: "Nothing"
Cons: "Over 45 mins for bags to get on the belt ? Ridiculous. Won’t fly with AA again"
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: "-Efficient Boarding -Great flight attendants -Communicative Pilots (flight time, number in line on runway, etc)"
Cons: "Did not dislike anything on this trip."
Cons: "Not enough time in London to change planes. We missed the flight"
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 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"
Pros: "Like the clean, comfortable seating. Great crew service and in time!"
Cons: "n/a"
Cons: "The departure was delated more than 30 minutes and the arrival disembarking was to slow."
Pros: "United crew were incredibly kind and accommodating. We had 2 lap babies and a 3 year old. They took our carry-on suitcases and checked them through to our destination without charge -- freeing up valuable hands in the process. They also arranged seats to make sure there were enough air masks for us and our 2 lap children. Our 3 year old had his own seat. In doing so, they moved me and 2 others so that my wife and I were in adjacent rows and there was an empty seat next to each of us (where our babies ended up sleeping). They were very kind and helped us in every way. Overall this was the best experience I've ever had on a flight, period."
Pros: "The final leg on a Delta flight was very pleasant."
Cons: "My final destination had a total of two flights a day available on United. The first leg I originally booked was pushed back and back and back b/c of weather. I was stuck at the Houston airport for 12 hrs after agreeing to take another one-stop flight, making it a total of three flights taking more than 24 hrs. I then had to cry to even get food vouchers. Where would I sleep? On the flor in the Houston airport, the most inhospitable airport I’ve ever been in. They have a hotel *in* the airport, but because it was “weather” causing the delay they refused to put me up. There was a woman whose birthday it was and she was trying to get to her husband having surgery the next day and a double amputee all in the same boat. It was absolutely a nightmare. I got maybe 1 hour sleep the whole night despite trying for 5-6. Never again will I fly United unless under duress or some emergency."
Pros: "Although I arrived a few minutes late, the check-in agent managed to get my bag on the flight. When I missed my flight, the agent quickly got me on another flight (with a competitor airline), with no additional charge."
Cons: "The short (10 minute) boarding window contributed to me missing my flight (by a few minutes). Very annoying."
Pros: "The price was decent. The plane was delayed by about 20 minutes, and they worked hard to get us on the flight quickly so we could make our connector flights."
Cons: "For a 5 1/2 hour flight, the only snack we got was one cookie. For the 4 1/2 hour flight, the only snack we got was a very small bag of pretzels. There is no TV. They give you free United wifi that you can use if you have a device to watch movies/TV on, but they don't have any outlets to charge the device, so it's kind of pointless. You have to download their app before the flight starts. I was having issues with the app on the previous flight, so I tried to get help with it before we took off. Our flight attendant acknowledged she heard my question and then just walked off and didn't help me."
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 had blankets waiting on our seats for us, which was really nice!"
Cons: "The seats were horribly uncomfortable and hardly budged when "reclined". It made for a miserable red eye experience."
Cons: "The seating was the worst I've ever had in my life and I've traveled my whole life. After I finish this trip I will never take United again. Everything else was wonderful"
Cons: "The flight was canceled because of the weather and then I have to wait more hours in the airport for the next flight.."
Cons: "The seats and headrests in particular were most uncomfortable for a 4+ hour flight. I was most uncomfortable on the flight and ended up with a pain in the neck!"
Cons: "One of the crew members was late to arrive, so boarding was delayed. However, The gate crew was amazing, very communicative and apologetic. During the flight the attendants seemed very agitated, I think a smile would go along way to improve the attitude of everyone. I also work with the public, I get that it is challenging, but I do believe that the simple gesture of a smile sets the tone."
Pros: "Crew was super pleasant and chipper. Passengers seemed to have a handle on how to board in a timely manner."
Cons: "Management could schedule time for maintenance software updates so as not to affect departure time. We were 20 minutes delayed."
Pros: "Nothing"
Cons: "Flight was delayed to 5pm. But left almost an hour early. Flight left without me. Not much notice to other passengers. Every airport display and the gate display said 5pm. Many passengers left behind"
Pros: "This airline is completely disorganized and with no apologies. I waited an hour in a bag drop line and then an hour and a half in the plane with no real explanation as to why. Planes are super bare bones which is fine. They just seem to be incredibly understaffed and unorganized as a company. All of the attendants and desk workers were trying their best but were set up for failure"
Cons: "This airline is completely disorganized and with no apologies. I waited an hour in a bag drop line and then an hour and a half in the plane with no real explanation as to why. Planes are super bare bones which is fine. They just seem to be incredibly understaffed and unorganized as a company. All of the attendants and desk workers were trying their best but were set up for failure"
Pros: "Happy and helpful crew even though there were many upset and stressed out travelers."
Cons: "Extremely long lines at check-in at SeaTac, over 1 hour spent in line just to drop off a bag. My flight plus the two before me were delayed."
Cons: "I am handicapped. Can't stand very well or for very long. I had to stand in line for over 2 hrs. They didnt open the check in until 2 hrs before boarding. Then it was almost 15 to 20 minutes for them to check us in once they were there. I was Furious over the $45 each for the 2 bags I had. Terrible s huh ock.. a friend had 3 bags and was required to pay $170... Had to pay for pop. Wow... the seats were tiny and no padding"
Cons: "Dirty plane. Tight quarters. Mismanaged time. Unorganized. Not worth the 20 dollar discount in comparison to other airlines that have more comfort and don't charge an outlandish amount for a carry on. It was my first time flying Frontier, and needless to say I was incredibly disappointed. Loaded onto the plane until we were supposed to take off, then deplaned for what they said would be an hour of required maintenance (which I don't know why they didn't take care of ahead of time), turned into 3 plus hours. And they can't even offer a complimentary beverage? Unimpressed, all around."
Pros: "Efficient boarding, on time, nice plane, friendly crew. Plus good price point - upgraded to aisle row which helped with comfort."
Pros: "Crew was entertaining"
Cons: "Second most uncomfortable plane I've ever been on. Most uncomfortable was the frontier transfer directly after."
Pros: "Not much"
Cons: "Cost of bags, not understanding person in terminal during boarding, plane seats; I keep saying we will NOT Frontier again. I must have been desperate."
Pros: "The price of tickets. Plane was on time and crew were excellent. The plane was new and seats were comfy."
Cons: "We did not know we needed to ask for our seats at the time of check in. A little confusing when we got to the gate. It turned out fine with our sitting in the seats for emergency. They were very comfortable."
