The flight itself was fine, food was expired and gross, staff were mostly amazing! KLM messed up rebooking for our first two flights that got cancelled and we almost didn’t make it to Amsterdam for an additional two days

The flight itself was fine, food was expired and gross, staff were mostly amazing! KLM messed up rebooking for our first two flights that got cancelled and we almost didn’t make it to Amsterdam for an additional two days

I think I previously submitted my feedback about flight lead Katherine in a different field by mistake. Please see those comments. Comments for Hyd to AMS are it was good. The flight lead and service met expectations for satisfactory high quality service but the flight lead did not stand out as exceptional as did the leads on the other two flights so I don’t remember anything specific one way or the other besides the fact I was satisfied.

Flight lead was a gentleman with silver hair and he went out of his way to shake hands and interact with each passenger seated in business class. A medical emergency took place during our flight and he handled it with perfect poise and professionalism. He was gracious and confidently competent. Just what you want from a leader,

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

It was operated by Delta. Boarding took a long time. How difficult can it be? Overall decent trip. Liked the Salt Lake City airport. Better option than Chicago for transfers.

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

The counter person at the gate was rude and demeaning, to the point that I wouldn't fly this airline again.

We couldn’t take the direct flight back home in Florida because the flight in Palermo was delayed flor long time and keep us inside the cabin without moving the plane. The plane from Munich to Orlando was still there when we arrived to the gate but they said it was late for us to board the plane. We rushed the most to get there. It was a bad experience and got back exhausted and with pain in all muy body. We are seniors 72 and for us was very bad

ok, butt flght was delyed for 2,5h from Frankfurt, and next Flight to Columbuse same

Very kind Lufthansa agent somehow gave us all no charge extra business class seats and helped us get home rested and happy.

Seats are complete BS for 10 hrs. The guy at counter canceled our return flight from europe. Lufthansa on the way back made United look like a trailer park gathering. If given the opportunity, I will never fly united again. Lufthansa seats werent much better to be fair but the service was a 10 out of 10. Incant express how difficult umited made my trip.

It was hot and not as comfortable as the flight to Chicago. Must have been a different plane that needs to be worked on or replaced.

The flight was canceled. I couldn't get on another flight. Meal voucher wouldn't work. The whole experience was a clusterfuck.

Food was not great. Small seating area for business class

United was excellent. We had very good experience flying the carrier. Certainly. We will opt to fly them for sure. Lufthansa is out.

Short flight, but no drink/snack service. The flights both going and coming were delayed.

That was the last time I booked Kayak. The connecting flight got canceled and the trouble shooting terrible. Next times, I will book the airlines directly. Good bye

I want to highlight the crew members and their excellent work and professionalism. They work hard to make a long trip the most comfortable as possible, the food and drinks they offer are pretty good. And they are always asking if you need something else. I have had experiences with other airlines where you have to basically beg for a bottle of water. This is not the case. Highly recommended!!!

Way too crampled. Charge more and put in less seats.

The seats on Lufthansa’s international business class on the A350-900 is the worst product in the market. Our chief purser was AMAZING though. She is the best FA I have had in many years.

the blanket was great and pillow helped. really need a toothpick packed with meals

This was the worst flight of my life. Economy seat directly behind a premium economy seat with extra recline meant I have about 6 inches between my face and their chair. My seat would not recline at all. I couldn't even use my laptop on the tray table because I had so little room. I was in a casket basically for 10 hours. Completely unacceptable.

Very comfortable plane. The food was very good (for airplane food). The crew was great

I liked the flight, the attendants, and the comfort. But the gate for boarding was poor. Even the elderly had to climb down many many steps to the bus and climb up to the plane.

Cancelled 90 min AFTER Departure! We had to deplane and wait another hour plus for the flight to be shown as cancelled for the customer service team. There were many many angry customers.

Good and they are leaving at time and arriving on time

I have a walker I need it to get from the plane to customs and baggage claim. It had a huge orange tag on it saying it should be given to me as I got off the plane. It was not and the flight staff didn’t know where it was—both on my flight to London and on the return. In It was very frustrating

Late lights, lost baggage and cramped seats. Did not feel that lost baggage was a priority. Communication was slow and often unclear.

Had a plane! Have a plan! Have my luggage! 10 hours of travel turned into 50 hours. Good Lord!

The travel on premium economy class was very positive. Comfortable with plenty of space and leg room. The service throughout was top notch. Crew members were kind and helpful. Food and entertainment were excellent.

Based on my wife's damaged condition, BA very kindly upgraded us from cattle to business class. MUCH appreciated!! One of these days, as it gains more experience, BA MAY learn how to depart on time (with over 30 years experience with BA, no flight has EVER managed to leave on time), Once airborne, the entertainment was ever so very pedestrian. But the flight was uneventful and the cabin crew's service was superb. And whichever driver landed the aircraft had obviously done it before. But BA unfortunately is learning from that scuzzy airline Delta. Delta is ALWAYS stunned when one of its aircraft actually turns up anywhere and is NEVER ready to receive it -- even when it turns up where and more or less when it is supposed to, NOT an example worthy of emulation.

Incredible. The upgrade to Business was a phenomenal way to end my trip, beyond grateful for the generosity and hospitality.

Great! Apart from small sitting in one the flight everything else was good

OK. Needed more information on baggage details with different airlines and airport baggage pickup Also, it appeared they offered free WiFi on their info publications but none did.

They ran out of headphones so my 3rd daughter couldn’t use the onboard TV the entire flight. They also rain out of food, so my 1st daughter didn’t get to choose her entrees or snack (chicken or cheese) because by the time they got to the last row they only had chicken left. Luckily she is not a vegetarian.

Spending 10 hours on a flight with no video or wifi access due to issues per stewardess was not enjoyable nor acceptable. Will follow up directly with the airline as well
