Pros: "Usually we fly United on a direct flight to PDX. That flight is no longer available so we chose Alaska to Seattle.

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: "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."

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!"

Cons: "need more space"

Cons: "Wifi didn't work. Very dissappointing."

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: "Smoothly"
Cons: "Food"

Pros: "Timeliness and that it met expectations."

Pros: "All of the staff were very accommodating and incredibly nice. From check in addressing us by our first names, to how quickly we were able to access our bags when we landed. My wife and I travel fairly frequently and we found all of our flights (each 5 hrs min.) were very pleasant and would recommend this airline to anyone considering traveling."

Pros: "The crew was amazing."
Cons: "Cleanliness"

Cons: "Compared to Virhin Australia crew, Delta staff seem almost poorly trained in comparison. For example, Drlta crew don’t check your pass, don’t immediately move down the aisle to move along tourists busy discussing their seats and then line up for Boarding seems chaotic at best."

Pros: "Nothing"
Cons: "Nothing"

Cons: "Departure delayed by 1hr30"

Pros: "Coming from Europe Alitalia and Delta did an EXCELLENT job at assisting the passengers get rid of their luggage just as soon as we were done going through customs... I don't usually fly on this route, but I thought it was perfect. Transfer between Delta terminal was a breeze too..."
Cons: "I usually don't fly from JFK. The food court was expensive (18 dollars base price from a burger seems a high even for an airport. I don't fly from NY normally - so maybe I need to tune my expectation for the locale, and it may have NOTHING to do with the airline company."

Cons: "Old cramped untidy and limited drink service"

Pros: "Nothing"
Cons: "Multilpe delays"

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: "Alaska Airlines is way overpriced and way less comfortable than Delta. I’m a Delta loyalist forever now!"

Pros: "Fast and efficient boarding again! Most impressed!"

Pros: "everything was very nice"

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!"

Pros: "Enjoyed food and movies.Woul"

Pros: "EZ play newer plane nice staff"

Cons: "First time wearing face mask all the time. It was okay."

Pros: "Nothing."
Cons: "When I arrived to check in at 5:48am for my 6:20am flight, I was treated very poorly. The lady at the counter asked me what time my flight was and I said 6:20 and right off the bat she was extremely rude and said that I missed the flight. I panicked internally and asked her how that was possible?! She said the cutoff was at 5:45am and I missed it. I asked if there were other flights available today or tomorrow and she said there was nothing she could do and that I had to call the booking company to see if they could book me. I wanted to cry because my friend had just dropped me off and I called to see if she was close enough to turn back. Luckily she hadn’t left yet. I called the booking company and they were able to book me a trip for the following day but they charged me an additional $100. I wish they had disclosed that we need to be there 45 minutes to an hour early otherwise you miss your flight. And it’s ridiculous that I had to pay an extra $100... financially it was stressful due to the covid 19 situation. I was extremely disappointed in how the lady at the check in counter at American Airlines treated me. She www extremely rude and I have never been spoken to in a way that made me feel attacked."

Cons: "Difficult finding room in over head bin for carry on bags."

Pros: "I will NEVER fly UNAmerican Airlines again."

Pros: "On time and the staff was great"
Cons: "Nothing"

Cons: "in the airport, the gate area dirty!, bathrooms dirty, no place to charge phone. The walk to the airplane, getting aboard the plane after the gate and flight changed and delayed. Being told it was weather related on the plane and being told it was MAINTENANCE by customer service. The plane was very crowded, the flight attendants never smiled. WHen i told the attendant i was being "rained" on he said...i know its happening everywhere..... he said there was nothing he could do but get me paper towels...they never came. I was very annoyed getting off the plane walking back and forth....it was aweful. and my flight before this was no better i am VERY TURNED OFF BY AMERICAN AIRLINES RIGHT NOW."

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: "loved having a movie to pass the time. Super friendly attendants."

Pros: "Was able to change my seat"
Cons: "The tone of the flight attendant (male) who can through the cabin to check things before landing. He was brash and abrasive. Yes, safety first, but overall not a good look for someone in a customer service industry. you can accomplish the same goal with different delivery"

Cons: "N/a"

Cons: "We haven't left yet"

Pros: "Got me to Dallas"

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: "The flight was delayed and we had to wait in a long slow line, however , once we got to desk , the agent was very nice and we had already been rebooked on an Alaska flight. The resolution was acceptable but it made for a 12 hour travel day instead of a 4 hour travel day."

Pros: "Seats were fairly comfortable"
Cons: "No in flight movie"

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."

Cons: "Fat constantly moving man next to me"

Pros: "free entertainment"

Cons: "They boarded group 1 all at once. I was group 2. They boarded all of us all at once. It was a cluster!. I haven't flew in 6 years. But when I did they boarded by so many rows. Not all at once . Boarding was horrible. It was like a cattle drive."

Cons: "Delayed"

Pros: "Just wish the boarding was better"

Cons: "Little planes need an interior restoration to make them look better."

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"

Pros: "They smiled, gave a friendly farewell, made sure everyone was hydrated."
Cons: "Don't get an attitude with calm passengers asking for assistance for their seatmates. Sometimes they wouldn't ask me what I wanted to eat or drink, they just assumed I already heard them ask other passengers and just waited for me to answer. It just seems lazy to me."

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!"

Cons: "Cabin felt quite warm"

Pros: "I like flying Lufthansa for entire trip then changing to united airlines"
Cons: "Particular everything the airline"

Cons: "I missed having the navigation map when traveling such a long distance."

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: "AlwYs on time"
Cons: "Cramped"

Cons: "We were asked to be at the airport 8hrs ahead of time, so we arrived 3am. United desk workers arrived at 4am."

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: "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: "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: "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."

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"

Cons: "My 3rd old was very hungry and I reached out to cabin staff for any kind of food for purchase, they turned me down saying I need to wait for another hour till the dinner time. Did not provide any help there."

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: "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."

Pros: "Nice airports and easy trip"
Cons: "My knees were a row in front of me the whole flight, seat didn't recline, which made it uncomfortable for 5 hours"

Pros: "It doesn't matter what I do, with United I always end up in Group 4."
Cons: "The scrum to get my small bag into a large overhead bin full of almost suitcases"

Pros: "The flight crew was great on both of my flights!!"
Cons: "I could not get the entertainment to work on either flight :-("

Pros: "Kudos to staff during difficult weather"
Cons: "Late notice for cancellation"

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

Cons: "Delayed, Late in landing, bad seats"

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

Pros: "Nothing"
Cons: "At least let the people with no baggage go 1st"

Cons: "Nothing."

Pros: "Plane interior was bright and new."
Cons: "Baggage retrieval. Chairs don't recline."

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: "The plane was very hot"

Pros: "I liked the fact that I can fly red eye."
Cons: "I typically fly Southwest because of the free leg room, free 2 bags checked, and 2 free carry-ons. Frontier "fee's" flyers to death. I have to pay extea for leg room????!!! REALLY! I could see if i was 6'6" but I'm not. If Southwest ever offers red eye flights I'll never patronize Frontier or another airline again."

Pros: "Nothing"
