Pros: "Arrived in PDX 15-20 minutes early."
Cons: "Social distancing on the seats"

Cons: "More communication on the flight delay"

Cons: "Hopefully upgrade on monitors (touch screen was not working),"

Pros: "Pretty much everything"
Cons: "Food somewhat expensive..... boarding off the plane - ones with no baggage should get off first then more control about everybody getting in the aisles trying to get their luggage and holding everybody up"

Cons: "The snacks were limited. They only had cheez-its and no cookies."

Pros: "The agent at the bag drop was very helpful. We had two reservations and she took the extra step to call someone and helped check our luggage all the way to destination. Thanks for the wonderful service. Flight attendants were all smiling and very friendly. A very special treat that we got two snacks each which were very much appreciated as it was an early morning flight and we didn't get a chance to get breakfasts."

Pros: "I like having the adjustable head rests."
Cons: "There was no window in the back row of seats, which was claustrophobic. The seat rows are too close together, that it was hard to focus on the movie on the seatback in front of me. My seat didn't recline at all."

Pros: "The crew were so kind and professional"
Cons: "The flight delay was a pain"

Pros: "The crew was awesome. The entertainment was great with a huge selection of movies. The food was really good."
Cons: "Boarding was delayed while waiting for Delta agents to come and assist people off of the plane."

Pros: "great crew and very welcoming for me and my small dog."

Cons: "Couldn’t hear boarding announcements. Lots of boarding confusion"

Pros: "The crew was amazing. Especially the pilot and copilot"
Cons: "Boarding process."

Cons: "Let was a typical flight. About all you can hope for is that it is on time. That makes it excellent."

Cons: "Great flight. On time and friendly staff."

Cons: "At least free water"

Pros: "Amazing crew, on time, decent coffee, plenty of drinks"
Cons: "The drinks cart was a little slow..."

Pros: "Good movies; nice crew"

Pros: "Boarding time, and timely departure"

Pros: "The cockpit crew waited to turn the plan off until the Footbal playoff game was finished. I thought that was very considerate of them."
Cons: "Seats were right but that I guess is to be expected these days."

Pros: "Friendly staff"
Cons: "Cramped seats"

Pros: "Not much. Boarding by "zone" works ok, but is no quicker than most other boarding methods."
Cons: "Boeing 767-400ER seats had no leg room for 6'+ traveller like me. The entertainment system was so old that there were no 115v outlets or USB ports. On a 7-hour flight, that is a significant problem for travellers today with multiple electronic devices. Finally, we were not told in advance that we had to go through security twice and through US Customs BEFORE leaving Dublin. So, the 6-hour layover at JFK was a complete waste of our time as we did not have to go through Customs there."

Cons: "Was not allowed to check in even tho flight was delayed. Horrible!"

Pros: "The Delta service desk was great! We wanted to get an earlier flight home and the Delta Rep got us on standby quickly and with a smile."
Cons: "Some chaos getting on the flight. The area they have set up for the different sections to wait before getting called weren't marked very well so everyone was bunched up and confused. Once they started calling the sections it was fine. Not sure why they even had the marked areas."

Pros: "It was a short easy flight that actually landed early."
Cons: "Nothing"

Pros: "We were in the plane for 3 hours before we could depart. No one offered us a drink or snack."

Pros: "Nothing"
Cons: "The poor service provided to customers when a flight gets delayed, there was no explanation, no gate, we were walking around the airport without any information and the food voucher barely cover a meal."

Pros: "I missed my flight and was not able to rebook any of it, losing 600 dollars..."

Pros: "Updating delay information"
Cons: "Chaos on boarding- Growing number of wheelchair boarding."

Pros: "That the planes flew and i met my connections and arrived home."
Cons: "Below average crew with little to no interest in doing anything but getting the flight over. Cool, and perhaps lazy or tired. We were told there was not good offered on the flight because it was not long enough. Minneapolis to Spokane - seriously????5 days earlier on same flight there was full food offerings. Audio quality and ear bugs are barely useable. Very difficult to hear any of the spoken words of the movie and I have good hearing."

Pros: "It was crouded seat were uncomfortable otherwise ok"

Pros: "Boarding, checking in etc. The usual stuff, nothign spectacular."
Cons: "Seats are getting too crowded!"

Pros: "On time departure; good updates by flight deck; luggage arrived unscathed."
Cons: "Once beverage service was complete, flight attendants retreated to the back of the plane. On a 4-hour flight, it would have been nice to have someone come by and ask if we needed anything, such as water, coffee, or juice. Granola bar was good."

Pros: "Loved the safety presentation made by the live stewardess!!"

Cons: "Smooth"

Pros: "The Gogo Inflight wifi and entertainment did not work for even a minute. I choose flights based on their amenities and this one had offered full WIFI service which swayed me to choose to fly with Delta. I'm not sure who is to blame about this issue but I'm pretty frustrated that it was completely dysfunctional."

Cons: "Kids yelling"

Cons: "There was a loud ringing sound at boarding & it continued through the flight. Very annoying. Hurtful to my ears."

Pros: "ability to book a later flight when I missed my connection through the delta app."
Cons: "Delays, missed a connection, booked a new connection through the app and that one was delayed as well...what was supposed to be a 3.5 hour experience turned into a much longer one. Seats do not accommodate people over 6'2" abiet very poorly."

Pros: "The friendliness of the staff and movie choices"
Cons: "Seat space"

Pros: "The courtesy of the staff and the seats in the "delta comfort" section."
Cons: "Too many interruptions. i'm not sure if there is a way but there should be a way to only serve only those who are requesting service."

Cons: "Boarding was a mess"

Pros: "Reminds of when air travel was a special event. The Salt Lake based crew was awesome. Cost to upgrade to 1st definitely worth it."
Cons: "Everything was great."

Cons: "I sat in a window seat and they put a 350 lb person in the center seat. For 3 hours I was squished against the wall. Flight attendants noticed but did nothing to reseat either of us."

Pros: "Friendly crew, on time"

Pros: "Nonstop quick flight"

Pros: "Excellent service and on-time"
Cons: "Baggage charge"

Pros: "Nice chairs with built in pillows. J"

Pros: "Free movies, lots of leg room, interesting for purchase food items."
Cons: "Food item selection limited - they only had snack boxes. The options looked interesting, but didn't quite taste as good as they sounded."

Pros: "Same as previous flight."

Pros: "Inflight movies"
Cons: "None"

Pros: "I liked the crew"
Cons: "Almost everything"

Pros: "The food and the crew"
Cons: "Entertainment system, it is outdated"

Pros: "Arrived early. Great crew."
Cons: "Movie selection is a bit stale"

Cons: "Flight was canceled due to United's mismanagement of crews."

Pros: "Crew was great. Planes were on time."
Cons: "Takeoff and first half of ORD-MCO leg was a little rough. Not the airlines fault though."

Pros: "Clean, comfortable and on time."
Cons: "Nothing"

Cons: "No screens in the seats. Food options are the usual limited fair"

Cons: "I’m 6’3, misty in my legs, so the diminishing legroom is a problem. Can’t afford business class either. You should really have entertainment for a 5 hr flight."

Pros: "Comfortable seats with screens"
Cons: "Mediocre snack"

Cons: "I didn't get to get on the flight."

Cons: "Slow boarding, no food no drinks, no tv."

Pros: "Flights went out on time, almost"
Cons: "The number of people who bring far too many and too big luggage onto the plane as carry on. I paid for my bags to be checked and then see how many people are breaking all the rules. This delays flight departure and causes frustration and anxiety onboard"

Pros: "Nothing"

Pros: "Más espacio, al menos una película que ver, y algún bocadillo por ser un vuelo de tantas horas"

Pros: "The pilot"
Cons: "Everything else"

Cons: "While it is cold in Duluth, our feet were very cold on the flight to Chicago. The next let was perfect to TPA."

Cons: "Flight was canceled"

Pros: "Entertainment worked on this flight! And once again, I had an empty seat next to me - that's always a huge plus so I can stretch a bit."

Pros: "The flight crew was very attentive and friendly. Probably one of the nicest crews I have encountered on my flights."
Cons: "Me and this other person were waiting in the back for the two bathrooms to become available. We waited over 10 minutes."

Pros: "Flight attendants tried but could not change situation"
Cons: "I losr one of two days- moving furniture Have to stay up another night to getready"

Cons: "Flight delayed in duluth. Missed connection in chicago. Added 6 plus hrs to my travels. I could have driven"

Pros: "The plane took two hours to leave the ground due to weather. This was unfortunate and made the passengers uncomfortable but it was not the fault of the airline."
Cons: "The airline gave all the passengers access to the movies and television channels."

Cons: "Price from Duluth is ridiculous!!"

Cons: "My luggage didn't make connnection."

Cons: "seating at the exit row so no screen and wifi did not work so no private screening"

Pros: "So they lost my bag but where super helpful and nice!"

Pros: "First flight delayed once board to check a broken light. Then waisted 40 minutes taxiing on tarmac in Houston because they couldn't find a gate. Missed our connection. They put us up in a low end hotel overnight. Then we had our morning flight again delayed as we waited for planes to the take off, so further delays. Arrived in Costa Rica 1 hour late. Now with too many other flights so immigration packed and took another hour and twenty minutes (when we finished there was only a 5 minute wait). Thanks United"
Cons: "Coffee and cookies. Moscow mule"

Cons: "Snack offering was caramely sugar cookie"

Cons: "Fligh delay."

Pros: "Attendants were amazing"
Cons: "We spent the whole delay on the plane and wasn't notified of a problem until after an hour. A lot of my time was wasted. That's not okay. Keep your customers informed."

Pros: "The boarding process is terrible, because communication breakdown is inevitable. The crew on the plane are sometimes rude, and have no patience when passing seated passengers. One air hostess constantly bumped into my arm like a bull as she passed walking down the isle. Entertainment is practically non-existent on long flights unless you pay for it. Two of my flights were cancelled last minute with little to no remorse, and I had to wait 2 days to catch the next flight. That flight was even delayed more than an hour. I was sick by time I reached my destination. Overall, United would not be my 1st choice due to bad experiences numerous times."

Pros: "Since we were the last ones to arrive at the gate because of our delayed flight they had to check our carry-on baggage with the luggage we didn't have locks and nomally what we carry in that bag are fragile or valuable things. They should at least have plastic gauzes or fragile stickers to put on the bags. I don't know the reason but the flight attendants left about the last 6 rows of passengers without pretzels or drinks. There was no device to view movies. Leg space too tight."

Pros: "Nice and comfy seats, good service on plane, fast boarding"
Cons: "No good food and the entertainment was not the beat"

Pros: "Just the crew"
Cons: "Now when I fly united i feel like flying with spirit or jet blue o any other cheap airline, they charge for everything but sodas. They don't even carry blankets. The fact that for a long (3h- 4h and 5h) flight (took 4 overall during the holidays) united didn't offered ONE movie for free at least was very disappointing. Not one of my flights were on-time!"

Cons: "Same. No ffood ..poor Service and allso charging. To much for extra weight. $200 for 3 extra pounds. Ridiculous. Also charged for one check in bag..Todo much"

Cons: "Viajar en United es desastroso. Los asientos son demasiado pequeños, yo mido1.57 metros y no me podía ni mover."

Pros: "Changed gate burt never notified those in the waiting area...and left the original information up at the discontinued gate so there was not way to know that the gate had been changes"
Cons: "just about everything"

Cons: "Duluth flight late (always)."

Pros: "Plane pushed away from gate a few minutes early bad was actually airborne two minutes after scheduled departure. Arrived early!"
Cons: "Seat didn't recline at all"

Pros: "I did not like anything .We had four hours of delay. They did not even have the curtesy of giving us something to eat."
Cons: "At Chicago they charged me # 25(dollars) for my bag that weighed Twenty Five pounds. Why? When I left D.C. I had the same bag with me in the plane. When I asked the people at the United Counter no body could give an answer."

Pros: "The staff was really polite and were willig to answer all questions with a smile."
Cons: "The seat I was on could not be reclined. This was most unpleasant because it was an overnight flight. You should earn the clients - even economy passengers - when this seat is the one being assigned to them. I would payed beforehand to get a more comfortable seat if I'd known I was to fly on a no-reclining seat on an overnight flight."

Pros: "Nothing"
Cons: "They delayed the flight due to "operational difficulties". I understand this happens, however, their communication towards customers was unacceptable. They first announced a 20 min delay, followed by another 30 min, then 30 more and then 30 more than then 30 more! They basically kept us at the gate for 2 1/2 hours until the found another plane. For a business like United, and flying out of their hub this is completely unacceptable. We ended up leaving at 11pm for a flight scheduled at 8. They didnt give anything in the plane to make up for it. No food, no free wifi, nothing."

Pros: "The seat next to me was empty"
Cons: "United put my bags on the next flight to San Jose, so I had to wait an extra 2.5 hours in the airport for the next plane to land in San Jose, Costa Rica while my ride waited for me."

Cons: "The seats were so small, with no space between rows that you couldn't even recline. The tv on the seat in front was so close you couldn't watch it. Miserable flight, and I'm only 5'5"."

Pros: "Terrible"
Cons: "Everything"

Cons: "I felt like tuna in a can."

Pros: "The crew was nice."
Cons: "Less leg room than any other airline, complementary food is real bad, they charge you for everything, movies, alcohol and food, in other airlines they do not charge you for none of the above!"

Pros: "Na"
Cons: "Na"
