This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

This flight was a first class choice and left much to be desired. Seat backs on seats were falling apart and torn. Seats actually didn't come to a "full & upright position". Pull out table was sprung. Not any significant leg room. All in all we were on an obviously older plane and felt overcharged for what we received as first class.

A 12 hour flight during the day with one real meal service - are you kidding? Also the breakfast was one of the worst and not what was listed

Flight was delayed several times. At one point, they "pulled back" 15 minutes from the delayed boarding and sent a text saying we would board sooner than previously advised. The flight then was delayed again. And when we boarded, there was an unspecified technical issue which had us waiting in the plane for about an hour.

Delta is a good airline. I've never had an issue with Delta. I'll continue to fly with them until they show me that I shouldn't.

The only thing nice I can say is the flight crew was really nice and apologetic about the situation. They shared as much information as they had and advised us on what we could do about missing connecting flights. The boarding process was so slow. The gate agent was working by herself and should have had someone working with her. It took almost an hour to board because she was trying to board a full flight of people and provide customer service to everyone who was flying standby and/or had questions. It was really chaotic. This didn't help the fact that we were delayed and folks were missing connections the longer it took.

The gate attendants and the crew were terrible. Because of high winds, they needed to carry more fuel, so they had to get volunteers to take the next flight at 6 am the next day. They did a terrible job of it - our flight ended up taking off just under 3 hours of the scheduled time. I hope to never fly Delta again.

Did not realize internet screen was hidden between seats and no info printed!!!!

2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.

Very good flight crew and very nice people staff were incredible especially the gate agent

really nothing ...uncomfortable seating, cramped ....no better than a US short hopper flight.. never again

Amazing! Everyone was so nice and the food was so good!!

Cut out the nickel and dime pricing for "seat selection" and baggage, To do this on an international flight is just mind boggling. Seriously, why treat customers this way??? Nobody wants these hidden extra fees and everybody hates them. Also plane was too warm and no air vent, and water dripped from the ceiling at one point,

I have paid for extra legroom on my flight. My seat was broken and did not recline. The crew could not fix it and refused to provide me with another seat

Over all experience was good. However the connection time was too short at CPG. We missed our connecting flight to AMS as the passport control line was too long and by the time we got our passport control done it was too late I wish there were some SAS staff to help us out at the passport control center Though they put us in a KLM flight from CPG to AMS, That flight was also delayed by over two hours

I paid for my seat 💺 assignments for all for legs of my trip, SFO thru Copenhagen to Prague and back the same way. It cost 💲216.00 USD for all four seats. Despite this, on my return 2 flights, my prepaid seats were given away. When I spoke with the information services professional, she said she could not help me, nor provide an alternative seat equivalent or better than what I had. When I spoke with another representative, she was very rude, disrespectful, and did not help.

first of all, the grand person that I tried to upgrade to Business told me there were no seats available. I don't think she really knew how to use the system at all. They were lying to me then I went and sat at my assigned seat and I asked them again if they had seats in business class one of the hostesses proceeded to tell me now the flight is full. The flight was pretty full, but after we took off, there were at least 10 seats in business that they were not occupied so they lied to me basically and I'm really upset about that.

The flight was cancelled without explanation, and the replacement flight was late

No vegetarian option was provided for the regular meal or the pre-landing snack.

The Scandinavian flight was excellent, however the second flight was partnered with TAP Portugal which was not so good. crowded gate area with no chairs, delayed flight, bad boarding process, no entertainment system onboard, and the baggage didn’t get to the carousel until well over an hour which caused our taxi that was waiting to leave. Love SAS, hate TAP.

The flight was delayed by two de-icings. The seatbelt did not work correctly. It did not stay tight.

Everything was absolutely wonderful from check in to baggage claim. Staff was very professional and sweet. Will definitely recommend United to family and friends.

Aircraft was noisy, old and never dimmed the lights on a night flight even on business class! I flew 17 times on United and probably another 40 on other airlines United USA /Europe flights were the worst to include luggage delayed once going to europe and once coming back

Check how old the airframe is, some older ones have inoperable seat back entertainment or power.

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

Hotter than Hades in August. Why, why do crews think that in the winter when we are already dressed for cold weather we need a cabin that is 82 degrees. Even the vents were blowing hot air.

Unbelievably poor service from flight attendants. They didn’t even do water service on a four hour flight. Just disrespectful.

United is an incompetent airline. They parked the plane on the tarmac for an hour after arriving because they “didn’t have a gate available” it was actually some sort of lie because as we de planed there were approximately 9 open and manned and empty gates that we walked past. Many people on the flight missed connections for the hour long sit on the tarmac. Utterly baffling and incompetent behavior from United flight ops.

Flight was delayed. De-icing took a while. When we landed had to wait for another plane to vacate our gate. Just an overall bad experience.

I understand weather is an issue, but making us chase our plane down at five scheduled gates across three terminals in an airport the size of O'Hare was unfair. They'd have probably been better off to leave gates as TBD until the inbound plane is in final approach instead of running us all over the place. Also, props to the consistently-unprepared ground crew in Richmond for once again leaving my lane parked short of the gate because they couldn't have a crew in place on time with 2 hours notice...

Crew were all friendly and helpful. It was a short flight so just a beverage service with a cookie. After we were boarded the plane took about 45 minutes to leave the gate but it was New Year’s Eve so not shocking there was some delay. Overall good experience and very grateful.

After the door had been closed, the cockpit makes an announcement that catering is running late and it is not the airline's fault. It is their fault in the sense that we had to sit for 2 hours or more when we could have stayed in the terminal. Poor communications between catering and airline. This caused a young man to lose his temper and he went storming out hitting objects. He had complained to the gate agent that he had already waited at the gate 7 hours and when can the airplane leave? Airilnes do a poor job of explaining delays, maintenance issues, etc. whereas being truthful may gain more sympathy or understanding.

The flight was very smooth and the meal in business class was great.

The captain brought my 6 year old son into the cockpit and allowed him to ask questions, sit in the captain’s chair and talk about all the gears and levers. Made the trip very special for him.

I take this flight about 6-8 times per year. It is convenient and saves an hour or two by skipping PDX, SEA, PHX, or ORD (but it takes longer to get bags to the carousel than Alaska Airlines). I wish the food service were better (but they might cut back on it because it is a red-eye). The WifI seems to go down about an hour out of Anchorage, and then comes back about an hour later...so be warned if this is an issue for you.

Better service. No food options, but we did get drinks and a cookie.

Boarding was organized and timely. Food was mediocre, especially for first class travel.

We were 4+ hours delayed. AA is absolutely obnoxious. They just kept pushing back the time to the point where we did not get into Vegas until after midnight when we were supposed to arrive like 845pm.

My last flight on 25 Dec, it’s Christmas Day, everyone happy and very good mood. I really enjoy traveling with Americans Airlines from Miami to Minneapolis my home town after long flight from lhe to Doha then Miami. Thank you again to make my travels comfortable and relaxed. Best regards

The boarding process needs to be fixed. The zone don't work, especially when there is hardly anyone in zones 3, 4,and 5, leaving the majority of the passengers backed up in the aisle, especially because passengers seated near the front are blocking passengers who are seated in the rear of the plane. It would also help if the size of carry on bags was more strictly enforced.
