Monitor control didn’t work & couldn’t figure out how to lay bed flat so I slept very poorly. Cabin was very cold

Monitor control didn’t work & couldn’t figure out how to lay bed flat so I slept very poorly. Cabin was very cold

Excellent flight. On time. Great staff. Clean and crisp cabin.

The airline was fine, but I did want to share about Kayak's error through Underpricer. The original booking was purchased with ANA, and Kayak booked it with United. This is a mistake that should not be happening, since the price I paid was with ANA and that was my preference. I appreciate the efforts done to make this right by paying for the seat preference, but sitting in the back of the airplane under economy is not enough to make this error right. ANA Airlines was the experience I wanted considering this was a life time experience that my family and I wanted to have as part of our Japanese experience. Please work on your affiliation with Underpricer to make the right bookings that the customer pays for. In my situation, I could of paid less for a United ticket versus my original payment with ANA Airlines.

The Manila airport was under renovation so there was no business class lounge. The double security check was disorganized and the flight attendants were grouchy.

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.

Patrick and the whole crew were amazing! Hope to have this team for all my European trips.

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.

The plane (Mitsubishi CRJ) felt old, creaking and not very new. The crew was okay. Hot water provision was broken so hot beverages could't be served.

Best flight attendants ever! Very customer and service oriented, courteous, professional and helpful.

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.

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.

I was sent an email that said my card payment was not verified. When I spoke to an agent , he said my card was not verified and the flight I thought I had to booked was no longer available so I booked another flight on another airline(United). Later I got flight updates , etc., concerning my supposed first flight. So if I was charged for this flight on British Airways/American airlines, I need a refund.

Generally very good. I think their service is better than some other big names I used to travel with. Their food variety is second to none - and you can place order beforehand. Their seating design is a bit awkward for service, I'd say. Flight attendants must be tall enough - long legs and arms - to reach the window seat passenger while crossing over the isle passenger. Also appreciated the variety on entertainment.

Lovely big plane. Excellent take off and landing. Cabin crew were so nice. Flight in time no delays

Los Angeles to London. 25th of April 2026. Business class. I was flying backwards with a complete stranger snoring next to me. In Business class. Males and females, strangers lying next to each other. Seats were backwards. I paid for comfort. I got dizziness and stress.

The crew has always been great on BA. They are very friendly and accommodating. I like that they have vegetarian options already in the menu. And the free wine is a nice perk.) I noticed (both directions of my trip) minor upgrades/ replacements needed on the plane itself (touch screen didn't work with touch; bathroom light didn't go on). However, this is one of my favorite airlines.

There was a delay for the San Francisco-London flight, but we were all informed via text and email. The staff was very friendly and nice and the food was good. I do recommend that the airline offer something without eggs or something vegan for the vegetarian meal option. A lot of Indians are lacto-vegetarian, while some could be allergic to eggs/dairy.

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.

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

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.
