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.

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)

The baggage drop-off in Stuttgart is bad: after online check-in you cannot use the automated baggage drop off as indicated on the website. You can use the terminals but have to cue to 1 of three open and slowly working counters to drop the bags. took about 45 minutes wait time.

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.

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

Flight was delayed “due to earlier delays of that plane”, so we were nearly three hours late.

Crew was amazing, takeoff wonderful. The bathroom was disgusting from before takeoff the odor made the flight uncomfortable as you could smell the bathroom from the center of the plane where we were sitting. Smelled like raw sewage. My daughter was throwing up as we landed due to the smell and horrible turbulence as we approached Newark.

Airport terminal was outdated, flight was on a small jet with no wifi

Essy to get on. The hostess gave very little pop, the plane was late getting in, and we are still waiting for our bags. This sucks. :/

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.

Short flight - no food understandable. Flight was delayed for over an hour. Overall, it was good.

We boarded and buckled and then deplaned due to no pilot. Had to wait over 3 hours for a new pilot. Not weather related, just poor management.

Last minute gate change nearly caused us to miss our flight. Change was not announced or displayed in the main board at the old gate. Terrible communication. When we landed we had to wait 20 minutes because there was another plane at the assigned gate. Not the crew’s fault, but adding 20 minutes to a 45 minute flight sucked.

Lounge was top notch h with great variety of food and drinks. Cabin crew were great. Smooth flight.

My seat 3G did not go down fully and the buttons were not working properly

Great staff, great experience, made a 2 hour delay very bearable

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

My ticket was for Premium Economy and all the seats were taken, I was placed in Economy class and I’m looking for a refund.

Unfortunately delayed 2 hrs due to faulty tyre.. which had to be changed, but better safe than sorry.

Lots of legroom on the flight. No interaction from the staff at all on the plane. They only attended to the First Class passengers. There was no entertainment. Security I was body scanned even though I hadn't set off an alarm, my father-in-law in his 80s, was stopped and subjected to a through body search, told that they would have to place their hands in intimate places. There were several border guards present, and as we walked off we could hear the TWA officer talk about the procedure as if he was training. My father-in-law was a little upset about the whole process. A kind explanation would have been more acceptable, and it felt dehumanizing to him.

Needed a 6 hour lay over in Atlanta. How can this be avoided ?

Security area in terminal 3 needs to be made much nicer. Less claustrophobic and use of glass and big ceilings wouldhelp

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!!!

It was okay. Mothers with rowdy children should be invited to sit in front of them.

I had a good comfortable seat. There was nearly an hour delay. There was an accident with the champagne, but I was well compensated. These things happen sometimes.

I wasn’t allowed to board with my children. I was charged outrageous costs for basic carry on size luggage. The entertainment screens were outdated and not user friendly.

Well,I miss a flight to Stl with United,they send me to Stl with a different airline, but same day,which was great

NEVER TOOK THIS FLIGHT. LUFTHANSA CANCELED THIS FLIGHT WITHOUT ANY NOTICE. We were rerouted through Chicago on United airlines with a layover of five hours and then on American Airlines to St. Louis. The United club lounge in Chicago is good but there is no shower unlike Bangalore 080 lounge

At the gate I requested a change of seat to an aisle because of a medical issue, and I was graciously accommodated. Everyone was very pleasant and helpful.

Had to push staff to get good flight due to cancellation and delays for staff shortage

Tiny plane Had to gate check bags, a problem since we were flying back from an international vacation

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.

Great until k found out they never got my check bags onto the plane.

It was pretty decent mostly cause I have leg room.

They ran out of earphones so my 3rd daughter couldn’t use the on board entertainment the entire flight. They also ran out of food choices (chicken or cheese) by the time they got to the last few rows, so my oldest daughter, wasn’t given a choice. Luckily she isn’t a vegetarian because they only had chicken left.

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
