Cons: "Not delay the flight for 3+ hours"
Pros: "The seats were very comfortable even though legroom was limited in the basic cabin."
Pros: "Was gud"
Pros: "Good crew."
Cons: "Very tight spaces. No tv."
Pros: "Comfy seats, quick service."
Cons: "If you are in Zone 3 or 4 you pretty much have to check in your bag back there is no more room. Which I don’t understand and is highly incovienent."
Pros: "Service by the Delta team"
Cons: "Seats not roomy enough"
Pros: "great service, easy to get on and off, snack options and drinks were all great"
Cons: "Put me on an Aeromexico plane without a seat. When I went to get seat assignments she gave me very last seat with a “window” she said. There was no window. I was absolutely closterphobic"
Pros: "Service; security gate in NY close to departure gate."
Cons: "Arrival Gate in San Jose far from exit."
Cons: "Not much food offered on a long flight."
Pros: "Everything ran smoothly on this flight. No delays before, pleasant staff, great entertainment selection, okay food options, working equipment (e.g., tv in the headrest worked, seatbelts worked, lavatories were operational, etc.). This flight met all my expectations"
Cons: "The only hiccup was the wait time on the runway before take off. Not sure if that was the airport’s fault or the airline’s fault. We must have waited 45 minutes."
Pros: "I was traveling alone with my (cranky) infant son and the crew members were kind and accommodating. Though the flight was delayed by almost 2 hours, the crew worked quickly to ready the replacement plane and the pilot made up time and got us to San Jose as quickly and safely as possible."
Cons: "The original plane had mechanical issues, which caused an almost two hour delay while waiting for a replacement plane to arrive. Since I was traveling alone with my young son, after an already long previous flight, it made for a more difficult trip."
Cons: "Sat by the exit seat so the door was a bit more chilly. No food. Small entertainment screens with audio bleed through."
Cons: "It’s was the best flight in my life"
Cons: "Was in seat 16A and got bumped to 12E. If you know Delta aircraft, that's exit row window, for the EC (more legroom) but middle. The problem is that nothing can compete with the exit row for leg room and being crammed between two guys isn't an upgrade either. Plus, due to proximity, got sick. And the flight was delayed leaving - due to the late arrival from ATL (Delta HQ) which had a power outage. And no video entertainment. No meals."
Pros: "As always, the crew and amenities were first rate."
Cons: "We were initially told that our flight would arrive early. Then we sat on the tarmac for a half hour before anyone could be bothered to tell us we were waiting for the plane to be de-iced."
Pros: "On time arrival"
Cons: "Small aircraft. Loud engine noise. Biased treatment for tickets booked on non Delta sites"
Pros: "No vegetarian options in first class.. and go go wouldn5 hook up. Flight was an hour late...but that was ok."
Cons: "The pilot did a nice job of flying in and banking so we could see the view.."
Cons: "They delayed the flight for 11 hours and did let anyone know until after 4 hours of waiting and then the gate number for the new flight was wrong"
Pros: "Almonds"
Cons: "Seat, did not get upgraded"
Pros: "Fast and comfortable"
Cons: "No tv but understanding"
Pros: "Crew was curious and quick to think of alternative solutions."
Cons: "The flight was way too hot. They didn't have enough A/C and we were all sweating up a storm on the flight. The flight was also scheduled to leave 15 min early, but we ended up leaving 15 minutes late, it was odd. One of the bathrooms was out of order too."
Cons: "Smooth"
Pros: "The flight was very on-time and it reached the destination even earlier than expected."

Pros: "The turkey sabdwhich was tasty. Good movies."

Cons: "No trash bag in my seat for puking or bubblegum"
Pros: "Comfortable plane"

Cons: "There was nothing that I didn't like."
Cons: "Poor leg room compared to jet blue"
Pros: "Comfortable seating and clean interior. Flight attendants are helpful and courteous."

Delay due to no flight attendants were late took one hour to get a drink

Cons: "No charger at seat."
Cons: "Nothing"

Cons: "power plug didn't work"
Pros: "Free World Series viewing"

Cons: "Flight was late Food on trip was barely average"
Pros: "quick boarding"
Cons: "no outlets!"
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."

Cons: "Crammed unconfortable"
Pros: "Seat was ok in stiffness and padding"
Cons: "Don't like sitting with my knees propped on the seat in front of me when I'm only 6' tall. feel like you could give a touch of extra legroom for times like when you want something out of your bag crammed below the seat and you have to jar your neck sideways to reach it and try not to be in your neighbors lap while doing it."
Pros: "Staff was wecoming and friendly"
Cons: "Couldn't even access united's flight map without paying for movies. Seats are very small, large neighbor next to me used my armrest the whole flight and generally spilled into my seat."
Pros: "The crew were nice"
Cons: "Your entertainment sucks everything cost so much. There is NO leg room. Your planes I think are old needs to be updated."

Pros: "I slept"
Cons: "Provide real food. Board back to front, window to aisle"
Pros: "Everything went smooth"
Cons: "HORRIBLE CUSTOMER SERVICE FROM UNITED AND THE THIRD PARTY CONSOLIDATOR. Awful. Awful. Awful."
Cons: "The only negative was that after waiting to taxi (for almost 10 minutes), we received an announcement that it would be a little longer because they realized that the had yet to re-fuel the plane. That was somewhat alarming."
Pros: "The flight attendants were friendly and attentive to my needs. I like good service and friendliness so for this experience I give 5 stars"
Cons: "I was uncomfortable in my seat but that's expected on an airplane"
Pros: "All"
Pros: "Online confirmation"
Cons: "My seat assignments were changed and we were at the end of the plane next to the bathroom. I know I didn't put those. I don't like the fact that you have to pay for baggage and there is no food provided other than a drink and some really poor substitute even for peanuts. Southwest at least allows you to have a free baggage. It's not the fault of the pilot but it also is very bumpy. The flight crew was fine and it's just the uncomfortable aspects of having my seat assignment changed and the extra charges for anything that makes it comfortable."
Pros: "Wi fi movies"
Cons: "Tiny seats. I'm 6'1" and 225. All passengers need more elbow and leg room."
Pros: "Average experience. Mostly pleasant enough."
Cons: "United changed our flight with No chance to object. Then reassigned us to separate seats. We asked to be moved next to each other. We were repeatedly and rudely dismissed 3 times, at 3 different levels, as if we were in the wrong to ask. If not for the kindness of a fellow passenger we would not have flown together. Very poor hospitality training."
Cons: "Terminals were a bit far a part"
Pros: "Nothing, worst flight I've ever had."
Cons: "Dried throw up on the floor in front of my seat.disgusting. SO MANY FLIES IN THE CABIN!!! Crew seemed like they hated their jobs, were NOT attentive. wasn't cleaned at all. Plane smelled. Charge port didn't work. Tray was extremely dirty. It was the worst flight I have ever had and is making me dread flying United back home."
Cons: "Crowded seating."
Pros: "Nice cozy seat, but seatbelt was about 6" shorter than most planes-wouldnt fit a medium-large person."
Cons: "Paid a lot for an upgrade, and our bathroom was out of order, the stewardess was snippy, and my expectations were less than met."
Pros: "There were empty seats and the very polite flight attendant offered for me to move without me having to ask."
Cons: "I arrived at my final destination and walked to baggage claim. I was just standing there waiting when a young girl walked by me in a uniform and said rudely and almost annoyed, "do you have a question". I replied that I was waiting on my bag. She then said these are it and I said so my bag has been lost? Without any empathy AT ALL she again, rudely and now most definitely annoyed said Do you have your bag tag? I said yes and she proceeded to walk away to a corner office. I assumed I was to follow. She took my tag, no communication at all from her, I said what are you doing and she replied I have to file a claim. She then proceeded to tell me that Newark Airport was horrible and never travel through there if I know what's good for me. This was extremely unprofessional. I was simply wanting some guidance from her on what to expect etc. I had to ask her what my next steps were. She handed me a flyer and said if I had any questions to call baggage information listed on the pamphlet. I left. The next day at about 1 p.m. I called the number and the update said my bag had left the airport and was out for delivery. Keep in mind that I had to work the next day after the airline losing my bag and had to purchase shower items etc due to them being in my lost bag. Portland jetport and my home address is less than 40 minutes apart, yet my bag did not arrive at my home until 8:30 p.m. and I'm also not confident it would have ever arrived because I called around 7 p.m. and spoke with someone who called the delivery service to ask their ETA. I paid $25 to check my bag and yet it was lost. What did I pay for?! If I can help it, I will NEVER fly United again and I'll be certain to tell everyone I know about my experience with this airline."
Pros: "Nothing"
Cons: "Everything. Rather than a new delay each hour and being stuck at the gate would rather just have a set delay time later in the future so you can make other arrangements in time."
Pros: "Nothing special"
Cons: "Flight delayed twice"
