Plenty of leg room, temperature was great and staff was excellent. Would do it more often.

Plenty of leg room, temperature was great and staff was excellent. Would do it more often.

The ticket agents in West Palm Beach on Friday afternoon Nov. 7th were incredible in getting us on an earlier plane to Atlanta during the government shutdown. Had the taken our original flight we would have missed our connection. She did this on her own, We didn't even have to ask, and she did it all with a smile and showing genuine concern that we would be taken care of. We are very grateful and thankful. We fly often, and now we will be sure to fly Delta.

Flight delayed then cancelled. Misplaced luggage. Still do not have. Rented car 1100 mile drive. I had to buy some overnight Hotels clothes toiletries gas food at my expense. Still not home. Not sure where luggage is. Over 4 hours on hold to Felta

I truly love flying with Delta. They have always treated me with the upmost respect

Our flight attendant in FIRST CLASS was one of the worst I’ve ever had. She was not at all pleasant, nor particularly good at her service.

Everything went well and was good. Nothing exceptional, but no complaints either. Cheap seats are pretty comfortable.

Staff were friendly and happy. Delta could make sure passengers that don't have the app know of changes. Without Kayak I would not have known about the change of gate or the delay. Kayak was faster to notify me.

They ended up paying for the bag twice, but the counter wouldn't take my baggage receipt. Left it to me to resolve. Not sure how to resolve the issue.

The customer service before board was very rude and when I expressed my concerns about making the connecting flight she laughed and told me I bought the wrong ticket. I explained once it showed the flight was delayed it no longer let me change seats or anything. I was trying to upgrade to make sure I would get to the next gate on time.

Non stop on long haul is the way to go. Great experience

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.

1) SAS sent me emails that i could check in but that was just a waste of time because traveling to the us i actually had to check-in at the airport. 2) SAS evidently does not care about vegetarians as it does not offer regular veggie alternatives in the transcontinental flights.

Great logistics and timeliness as we arrived quite early. Flight smooth and fast. Excellent entertainment. Plane itself was a bit tired and the crew mostly indifferent. Baggage took forever but that’s on CPH. Would use SAS again for sure.

SAS has too many other airliners. They don't need to exist.

Only one choice for meal seats had no leg room

I didn't book special seats but the ones I got were great. The food wasn't good but on par with other airlines

Older aircraft, no meal, only food was for purchase. Not impressed United.

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

Always wish for more healthy, gluten free options. We have to bring our own.

Having a long layover, I was very appreciative of the ability to stand by for an earlier flight. Other airlines like Delta have refused this to me in the past, just to be mean (because my ticket class wasn't high enough). United went out of their way to help me get to my destination early, which I really appreciated given that it was the third leg of a 24+ hour journey for me.

Other than a way way too cold cabinets for the entire flight, all was great

One bag is incorrect and not acceptable for an international flight. The food was not just good. I won't fly with them again.

Not pleasant trip cross country when the entertainment and WiFi system not working. No entertainment for entirety of route. Staff was rather nonchalant in that they dismissed the problem due to age of plane. It would have been nice to know this up front so I could have come prepared to read or download movies before boarding Coincidentally or not, there was a similar issue with the entertainment system on my previous flight I took on my fist leg of the trip. There are no seat TVs, so you must rely on the app when it works. United can do better. Also, what use it it to pay for boarding group 2 when half of the passengers are in the same line as you?

Plane boarded early a quickly, was mostly full. We left close to on time. And landed early.

My experience on this United Airlines flight was highly uncomfortable, primarily due to two issues: Cabin Temperature: The temperature on the Boeing 737 MAX 8 was unacceptably high, feeling consistently around 80 degrees throughout the flight. This made sleeping impossible and significantly detracted from the experience. Seating Arrangement: Being stuck in a middle seat for a six-and-a-half-hour overnight flight compounded the discomfort. Moving forward, I will always purchase a seat assignment to avoid this situation.

Premium Plus is a really good idea for longer flights

we landed at cmh ten minutes early but had to sit on tarmac for twenty minutes because a plane was at our gate despite the fact that 3 other gates were open.

The experience with American Airlines was good, although the Philippines Airlines flight was much better (better seats, better food, better entertainment options, overall better). Again, the MIA to LAX flight was fine, but nothing in comparison to the comfort and accommodations of the Philippines Airlines flight from LAX to MNL.

I have a gluten allergy so did have any food

I have a gluten allergy so didn't have any food

Loved the crew . Absolutely no complaints. Except for luggage lost

Everything was good The connects, with no blame to crew. Or pilots. I understand they are short staffed. Everything went well for me. I'll be using you guys again in May if not sooner.

this plane was really old, had exit row seats and tray was in arm of seat so super uncomfortable to use. another seat they could t even use the tray it was broke. seat i. front of me had duct tape on it cause seat was ripped open... this plane should either be updated or retired.

We were very rushed by a staff member at the gate when transferring from American Airlines to Fijian. Then the plane stayed put for ages anyhow! The plane was delayed and my bag sent to San Francisco instead of Fiji

Baggage handling poor. Second time this has happened. My bag went to San Francisco instead of Fiji. No apology. Luckily Nadi airport staff are fantastic. My bag arrived in Fiji the next day.

We loved the steward on the plane. He made the night enjoyable
