The leg room in economy was sub par, everything else was fine.

The leg room in economy was sub par, everything else was fine.

Friendly flight attendants and reasonable good food. Quick service throughout the trip.

I WAS CANCELLED ! I thought entire flight was canceled but it was still ongoing and I was only canceled as a passenger and one day before my flight with really poor "choice" of next flights that completely ruined my family event. Absolutely disappointed by SAS. Will be avoiding this airline now

The flight was pleasant with landing and take off being very smooth. Toilets were a bit busy at times but crew was very accommodating. Food service was quick and hot. The connecting short flight was full and there was not room for hand luggage.

The layovers / connections were too short and too long. I SPRINTED to make the connection from OSL-JFK and then SAT for over 6 hours from JFK-BUF. I don’t mind a longer layover more than I want to RUN to make my next connection

Flight crew was very kind and polite. They had to deal with an unnamed issue right beside me, and did so with respect.

The layover was very long. Other than that, great trip so far

Elderly traveler with disability was bumped from extra legroom to economy with little legroom. He couldn’t bend his knee to fit in the seat. Very uncomfortable for a 7 hour flight and will be reported to DOT. Then the food was disgusting. Boiled chicken with boiled rice and steamed veggies. 3 slices of carrot and one broccoli. We couldn’t eat it. No salt or pepper provided. Disgusting.

Good flight. Mass boarding. Seats fairly comfortable. Food okay although may have upset my stomach a bit.

Airline left me stranded in the U.S. gave me an unrequested refund of 40% of booking and canceled my trip back! When I asked why, the said “we don’t have to tell you why”. “But you can rebook”. Never again! Paid 2x and rebooked on Austrian. What a joke!

Even though the incoming flight was delayed by 20 minutes they managed to get us to SFO 15 minutes early.

Gluten free snack options and meals that offer both gluten free and dairy free.

First class ticket gets you no seat back entertainment? I have to bring my own laptop to see a movie? And most of their movies have ADS? No thank you. Worse: Tiny snacks only on a 2 hr flight?

We purchase first class seats for the first time for multiples of standard economy ticket. There was no access to the club lounge and no priority boarding. The meal and the service once on the plane were superior and the seat was nicer, but not worth the price difference. I will be happy to seat in economy and spend the difference on more travel.

I upgraded my seat and was promised it would be next to the emergency door for extra leg room and they said it was premium plus but it was at the back of the plane...same thing happened from Newark to Dubai

Check-in, boarding and the flight from Phoenix to Houston was quick and easy. The flight from Houston to Shreveport was delayed 5 hours. It was frustrating but I think United handled it the best they could.

After boarding the plane in Chicago, the passengers were told that there was a technical problem with the plane. Passengers remained on the plane as they tried to fix the problem. After what was probably an hour passengers were told that there was a need to change planes as the problem was not solved. Passengers disembarked and boarded another plane. After taxing to the runway and waiting for takeoff, passengers were told that owing to the thunderstorm the flight was unable to take off but would try and reroute. After some time passengers were told there wasn't enough fuel for the new route and the plane had to return to the gate for additional fuel. after another log delay the flight got underway. On the plane there was food, drinks, ice or entertainment. We were a glass of water, which appeared rationed. Flight arrived about 5 hours late. The pilot was fantastic and communicated with the passengers throughout the ordeal.

The woman gate agent in Phoenix was none too sympathetic about my check-in process as I am relatively new with using apps. I almost did not get on because she said I did not check-in. I thought I had via Kayak where I purchased a very expensive ticket. Lesson learned but to be told I may not get on as a matter of factly was difficult to hear.

We were delayed 3x and because I didn’t purchase my tickets directly from United Airlines I was told I Have to take care of it myself so I called Underpricer and they helped me but before I changed my flights I took the risk of sticking by what my tickets were and was lucky to have gotten on the original all flight with only 15 mins before take off. not sure if I will do this again

Awful, rude staff. Their abrasive comments are unnecessary. Most seek a frictionless experience and will cooperate if you ask. Additional childish bullying of customers is not acceptable or tolerated. We had the same problem with our departure flight. We will never fly United again.

The new buisness class pods are 100% worth it. Loved it.

Pretty bad. No welcome drink (the Lufthansa signature drink they advertised but did not serve). No 2 round of beverages. No coffee to end your meal. No snack before landing on an overseas flight. Mediocre everything and unattentive staff. Munich and Frankfurt as connecting flight airports are terribly big (20 min walk for transfer!) and confusing. Will not fly again.

Seating was average for a first class seat. It very modern. I expected better.

The agent, who took my mother to her gate, kept talking with one of her male coworkers and treating my mother like a sack of potatoes. She was ignoring my questions because she was too busy flirting with her male colleague. This was a very unprofessional behavior. We also had to wait for close to half an hour for an agent to arrive.

Very good flight, only problem is the boarding process where some peoples do not have manners and do not how to fly ( preparing your documents, oversized carry-ons, not understanding or feigning to not understand directives).

The flight was delayed and I would have missed my connection so I had to be rerouted on a much earlier flight.

I really like it and travel to Europe and back with Lufthansa, but it is getting expensive, a bit beyond my me

Not available crew to load the luggage for all the passengers,comon situation for local European destinations , not acceptable situation, never Lufthansa again 😉 🙄

I had to rebook my flight or I should say I tried to rebook my flight and all I got was a complete run around. The response to my first call/request was "call back on the day of your flight". My second call/request was more positive and I was told that yes flights/seats were available for the dates I requested but to call back the next day as the price for the flight would drop. I called back the next day and was then told there were no seats available for any of the dates I was requesting which covered a period of all of April, all of May and all of September. I knew then I was getting a run around. I called my CC company and submitted a request to stop payment. They have done so. I will never, never book through KAYAK again and will never fly with Lufthansa. Finally, I am a seasoned traveler and have lived and worked overseas for most of my life. Never had such poor service.

Flight was overbooked. Crew did a great job but passengers weren’t nice and really not patient. Flying in these times is not the best idea tbh.

Would like to see clean bathrooms, especially the bathroom by the end of the crew flight the cleanest not the bestest thank you

The flight was excellent in World Travellor plus. Well worth the extra money. Boarding at Phoenix was the usual poorly organized event. Very stressful.

The onboard service makes it extremely difficult and slow to go to the toilet

So very uncomfortable! The seats were dreadful and the space in a middle seat was too small. I don’t know what I would have done if I were 6 ft. Tall. I feel like the airline deliberately made the seats so close together for the purpose of selling the more expensive seats. Economy is on thing, but there should be a minimum standard of care. The meals were taste free and soggy. I can choose not to eat the meal, but I was trapped in the seat- so overall the lack of seat comfort is the biggest issue on such a long flight. I have flown overseas British airways, although about 10 years ago, and it was a fine experience quite unlike this flight.

The BA team at Sky Harbor is deplorable, full of unnecessary attitude and poor communication. It seems like every member of the team was looking at another to solve the problem, instead of taking agency to do so themselves. I saw no less than 6 altercations with the same gate agent where he threatened to revoke the passengers boarding pass for asking a wildly reasonable question, something as simple as where the cue to board was. I’ve complained to BA before but it seems this isn’t an issue for them, which is very disappointing

The boarding process was a disaster. No one respects the boarding groups—tired old aeroplane. There are no sockets to charge phones. The cushion seats are ancient and hurts back and gluts

Baggage took two hours to arrive in hall after landing.

Do not book through Kayak with connecting flights. You have to deal directly with airlines if there’s a problem. Our business class BA Flight was delayed 2.5 hours. This delay would have caused missing flight to Aman airport. We had booked business class and BA scheduled us on cattle class in last row on American. Even thou there were comfort seats available. Beware

I like the way they are friendly and helpful . More food options.

Flight delayed at the phoenix location itself. Missed connection flight and the alternate route given was 1 more extra day. It was a horrible experience
