Delayed 2 hours while stuck on the aircraft. If the luggage was properly loaded the first time we probably wouldn’t have been delayed at all

Delayed 2 hours while stuck on the aircraft. If the luggage was properly loaded the first time we probably wouldn’t have been delayed at all

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

UA594 was delayed multiple times. I ended up getting picked up so I can make it in time for work 6AM on Monday, 7/6/2026

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..

Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.

Was a pain having to leave the plane and reboard but glad the plane was fixed

Connecting flights were poor,especially in Naples.our Lufthansa air bus was a joke.way too small for that long of a flight.no room at all.couldn’t even get out of the seats to move around or go to the bathrooms.we thought we were getting an actual air bus,double decker.i will never fly that long in a plane like that again.kind of misleading to call it an air bus.we actually had more room on our buses that we used.

For a 22 minute flight all you expect is for it to be safe and comfortable

Lost connnection had to stayON in Chicago Was a mess

Booked economy through United - air canada treated it as standby and was almost refused boarding.

Good and they are leaving at time and arriving on time

The flight attendants were wonderful - one man put my carry on in the bin for me. Very attentive service. Loved the blanket and pillow waiting for me in economy. Food was excellent which is a surprise given the reputation of any airline food. Wine was fine with the meals. Delighted with the new movies - flight went by very quickly. I would definitely fly Lufthansa again.

Generally good. Not their fault but the design of the Boeing 747 had seating supports directly in line with my legs. So my legs always had to straddle this support which caused body misallignment. Such poor design from Boeing. There was no USB port for me to charge my phone. The screen touch control was very poor.

Smooth flight with enough time for connection. Ran out of meal options. In-flight and gate staff were friendly and helpful. Good service overall.

They don’t give information on why a flight is delayed in a timely manner. Very frustrating.

I was very happy with everything, thank you for the smooth flight ✈️

Entertainment system is old. Food can be tastier Need to provide toothbrush and toothpaste at least when asked.

The food was straight up bad not gonna lie, seats are uncomfortable so I had to re-adjust my self most of the time, delayed our arrival time by alot.

It was excellent. I upgraded from premium economy to business and it was totally worth it. We were on a 747 and I sat upstairs and enjoyed the privacy. The crew was incredible especially the woman who had been working with you all for 30 years.she was absolutely spectacular as was her cabin. The food was delicious. I would just serve bread with the meal. Don’t take it away!

Wasn’t overbooked, so it was nice having an empty seat next to me. Appreciated the on time flight. Food was really bad though. Received stale vegetarian sandwich with just a slice of cheese and shredded carrots on it. Very strange and not tasty. I didn’t order a vegetarian meal either way of my trip but received all vegetarian meals because they said that’s all they have available.

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.

All service prior to the flight was terrible: online check-in not working, no customer service tel,, multiple airport scanners not working, A huge mess.

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

Service of the crews were great. Food on flight was very greasy, and salty.

Terrible, broken window and the blinded didn’t shut during the entire flight. Nobody could sleep

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.

Horrible. Crew is not helpful. Lounge is sub standard and overcrowded. Getting to your plane is underwhelming “via a bus”. Worst experience I have had.

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
