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."

Ran from gate F to gate c24 arrived at 10:23 p.m. Slight to the park at 10:25 p.m. and they closed the door on me as I was running up there. Ran across the entire terminal to get there and they would not let me on. Last Flight of the night to Bismarck. Missed my uncle's 90th birthday party. Would not give me food voucher. Delta gate agent told me she would lose her job if she did not close the doors 8 minutes prior. However the Minneapolis flight waited for 15 minutes for people to board that plane. How does that compute? Why would they not wait 3 minutes for me rather than pay the money to put me up in a hotel?"

Pros: "Crew is always friendly"
Cons: "Aircraft broke, had to route me to an additional three stops just to get me home and through the night. Also, still unsure of where my checked baggage is."

Pros: "On time"
Cons: "Flight attendants not friendly"

Cons: "It was ridiculously cold for 2 1/2 hours. When my seat mate asked for a blanket, the stewardess said she only had one more - then walked off. For drinks, they skipped several people. I had to catch her eye to ask for one and then ask her to get my kids a drink in front of me."

Pros: "Got me where I needed to go at the price I wanted to pay. - The gals at the ticketing desk were extremely helpful and cheerful."
Cons: "Not my typical Delta experience: -Boarding for special needs was a joke. A literal ‘run-on-sentence’. No more did I get up and they went to the next group. I was almost knocked over in the rush. -The onboard staff was nice enough. However, between the two of them, one of them had a thick accent. Maybe that one shouldn’t be the one making all on board announcements… and please fix the horrendous crackles too!!! -It seemed our pilot was in training… during our short flight a series of right and left turns were made, no effort to avoid turbulence, and the landing was surprisingly hard. It felt as if my spine took a quick jab to my brain as a result! What’s up?"

Pros: "Delta is the best airline by far."
Cons: "My bag did not make the connection even though there was almost 4 hours layover... :("

Cons: "Was not a wheelchair waiting for Wallace."

Cons: "Kids yelling"

Pros: "On Time"

Pros: "Delta made sure my husband and I had seats together and my husband was thrilled to have a window seat. We took off and arrived earlier than scheduled so we didn't have to run to catch our connecting flight."

Pros: "The crew was great, boarding and exit went smoothly."

Pros: "The crew from SYD to LAX was absolutely excellent! The food is always plenty and hot, and I really appreciate being given a whole bottle of water. Also, thank you for leaving snacks out for us especially those who sleep through the meal service. Very satisfied with the airline so far!"

Pros: "They had aircraft flying to my destination. All other airlines were booked for the time and the destination I had in mind."
Cons: "Long Delays, Over Booked Flights, Customer Service is not helpful, Wrong info delivered by Customer Service, No boarding gate info, Luggage was damaged, and I was charged a large premium with no added value. Delta sold me a 1st class flight because of their delays and overbooking their flights. This was because they could not fulfill the ticket I had. This was Delta's solution to their problem caused by them. I still have no idea why the flights were delayed. On top of all this, I overheard a walk-on pilot ask if there was room for him to catch a lift home. The flight attendant responded with "absolutely this flight is not full at all, you can sit right here". Wait I had to pay 200 bucks extra for an overbooked flight and you are having your Delta representatives say different. This was my first and last trip with Delta. I spent 1000 dollars for round trip ticket from Seattle to Spokane WA. No way is that OK or acceptable under any circumstances to treat your customers like this. The best part about all of this is, I have sent feedback and called customer service to talk to a manager to hear the blame put on back on me. Perception is reality Delta. Awful service, awful prices, awful care, awful communication, and awful value for the money."

Cons: "even though I paid for premium economy, the seating was still cramped shoulder to shoulder"

Pros: "Flight attendants were competent."
Cons: "Air conditioning was extremely noisy."

Pros: "I was upgraded to First at the gate. The crew was very professional and friendly. Food mini-minimal, but OK."
Cons: "On this A320 craft, old style, the First class seats are a joke. I had seat 2B. The pitch is apparently less than in the Comfort+ rows. The passengers in 1A and 1B started reclining even before departure, and during the whole flight. For me and my neighbor, with that seat on our chest, it was impossible to reach down to the seat-back pocket, not to mention to the bag stowed under the seat in front. To get out of the seat, I almost could not get my legs through the 5-in. interval between the back of the front seat and the irremovable armrest. I shook the passenger sleeping in 1B rather violently a couple times. The lady in seat 2B apologized, but she had to climb and put her feet on my seat to get out of hers, there was really no other way. Delta needs to address this ridiculous situation of their First Class seats urgently."

Pros: "Boarding was good"
Cons: "Boarding was good first time flying first class not happy with service when I wanted another Drink had to walk to very back of plane all the flight attendants were hanging in the back tiger no one was in the first class section. In the beginning of the flight took forever to get a drink I have had Reg class has better service. Flew Detroit to Vegas 4.5 hours"

Cons: "Confusion when boarding. Uncomfortable seat. No entertainment on a international flight! What kind of person thinks that is a good idea? I thought I will be flying British Airway for the flight back home that is why I bought this whole flight ticket. If I had known it will be AA flying back, I would fun as far away as possible."

Pros: "Nice people"

Pros: "The customer service/ticket agent skipped her lunch break to get us on the plane. She went way beyond the call of duty. We will be eternally grateful."

Pros: "They finally got us there."
Cons: "The airplane broke on the ramp and they made is sit in the airplane while the tempeture rose to about 100 degrees. I think someone was about to pass out before they realized they had to get us off. Then we were over 4 hours late departing while they were getting another plane"

Cons: "Nothing"

Pros: "The overnight flight made it easy to sleep most of the way."

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."

Cons: "Was delayed 45 minutes and by the time we landed and taxiied I had only 10 minutes to make it to my other flight for boarding. Barely made it."

Pros: "The flight crew was very attentive and friendly. Probably one of the nicest crews I have encountered on my flights."

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

Pros: "The time getting there on time or early"

Pros: "Left early...arrived early"

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: "We were delayed almost 2 hours. Sick of it every time I fly. Get it together. I missed my ride and had a 6 hour wait for a bus. Ridiculous!"

Cons: "Fligh delay."

Pros: "I was allowed to get off the aircraft to collect a bag I left behind"

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: "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: "You will refund for missed flights, everything was good"

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."

Cons: "Well considering I am still in Houston, the plane left late and I was in the last row and I it took 10+ minutes to deplane, I missed my connection to Corpus Christie!!! The schedule between planes is way to tight!! I am very unhappy and too old to be running to catch my connecting flight. I will never make reservations that the airline or kayak do not consider time needed to change terminals etched"

Pros: "The crew were nice though exasperated with cramped new planes and crowded restrooms. Flight was on time"
Cons: "After three years of flying all around US, realized United is the worst of the three major legacy carriers. I'm star alliance gold and it's still a painful experience. Crew admitted in latest redesign of planes they've managed to squeeze another six seats in coach. My seat wouldn't go back but even if it did, would feel too guilty for person behind to do it - so little legroom on newer planes. They've also cut down on restrooms so for most of the flight there was a line of 5-6 people waiting in the aisle. American Airlines seems to have older planes but at least decent legroom (and I'm not tall - anybody over 5'10 would have to sit at an angle on new United planes!). Been very impressed by Delta's service lately. United feels more like Spirit"

Pros: "Nothing because they didn't allow us to board the flight because there was 20mins left til the plane departed. Also the tickets were bought with 24hrs and they didn't refund or give us a flight credit."
Cons: "They didn't allow us tothe tickets were bought with 24hrs and they didn't refund or give us a flight credit."

Pros: "Meh"
Cons: "Our seats were Infront of the emergency exit, couldn't relax. I'm 6'6" , so the incline if the back isn't comfortable and we couldn't recline. We had asked switching seats on our flight to Spokane because we were given the same seats. The airline told us seats were chosen at random and they couldn't control them so we had 4 legs of our two flights stuck in no reveling seats. I was very disappointed."

Pros: "Wonderful experience the entire way! I did fly first class as I've decided if I have to fly all the way across country I want to be very comfortable, and I was! Thank you United!"

Pros: "On time. Boarded smoothly. Pleasant crew. Snacks and beverage included. No cost to check bag."
Cons: "Seat was uncomfortable."

Pros: "All of this trip went well, all on time, great service, no worries!"
Cons: "None"

Pros: "In flight service was nice. Attendants on plane tried to be helpful"
Cons: "Traveled with small children, could not get seats together. Made the journey rough."

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."
