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

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

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

There was a little turbulence taking off and landing but mostly it was too late for me to make my connecting flight to Greensboro. Everything else was excellent.

The seats were very nice in premium economy. The service was good. The flight was slightly bumpy. Would have appreciated more updates from the pilots.

The economy seat was much less comfortable for an international flight in terms of recline and moving space when food tray is expanded. Per entertainment, it would be amazing if I could connect my Bluetooth headset or ear phones to the entertainment screen. Or provide in-flight wifi to connect directly from my own device.

Meals were poor and service rendered on return flight was mediocre as compared to the flight we took to Germany earlier where the attendants were more attentive, energetic, and mindful of passengers' needs. Thumbs up to crew of UA 58. Thumbs down to UA 59..

The crew was generally professional. Though one of the crew members seemed to be easily annoyed, the others were fine and helpful. The green olives and almonds snack was really good. A great idea, and nice balance of tastes.

Airport terminal was outdated, flight was on a small jet with no wifi

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

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.

Horrible airport ever. We stood in the security check line for more than an hour. It was past boarding time and we were still waiting in line for the security check. With 2 children and a medically ill person we had a very stressful transit.

We missed our connecting flight in Frankfurt do to security and all hell ensued then.we got rebooked to Washington got there round 10 am ish didn't find out till 630 we were rerouted to United!! Then we started getting updates

Too tight connection. Lufthansa staff pulled 12 of us out of passport control that had tight connections and took us about 1/3 mile AWAY from our gates and put us in another slow, long line. Needless to say all of us missed our flights and the Customer “Service” staff was rude and not helpful at all. Was rebooked from a direct flight to one w a 6hr layover. Asked about an other option that was on my app and was told to book it myself online (which would be $300 extra pp!!). Got rebooked again w a tight connection which was also missed. Rebooked into middle seats that didn’t recline for 9 hr flight!! No compensation (and we paid for seats!) Ended up taking 26hrs to get home from Europe to North Carolina! No longer a fan of Lufthansa—2nd time having these kind of issues w them!

The food on this flight was better than what we had getting to Rome. The flight was comfortable and the staff was great. One of the staff members was a stickler about the blankets in the aisle, which I get, but still. Overall, great flight and will fly with them again!

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

Easy, straightforward boarding process. Flight attendant was lovely and attentive, food was delicious - especially dinner, I had the roasted chicken in a mushroom sauce with potatoes - and entertainment selection was top notch. I would fly with BA again.

I love FRA - LCY route. So much better compared to the FRA - LHR route and the price differential is ZERO

It's useless to complain about the space and the back of the seat, making you sitting vertically like a candle. it's your business model. The "food" - there is no food. But I don't care about the food. It's the seating.

Flight take off delayed 30 minutes; arrived 15 minutes late. Had to take bus from terminal to plane, delaying boarding and unloading.

The checkin experience was terrible. Once we got to the counter, it took them 40 minutes to check us in. Nothing complicated. Just 6 boarding passes and two checked bags.

Great crew! Average flight. T5 at Heathrow is not such as nice experience compared to other major International airports.

Our stroller got lost when flying from San Diego to Frankfurt and our luggage got lost when flying back from Frankfurt to San Diego, We had to rent a stroller during our 4 week stay and had to no stroller during our trip back to the US. Our suitcase is also still missing. We sent and email 3 weeks ago and are still waiting for somebody to get back to us.

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
