Terrible last row seats many seats available but no offer to move to better seat

Delay on my previous leg, had to run to catch my flight. But that happens. Overall ok.

At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

Couldn’t get boarding pass in SLC even with help from a redcoat, so had to find a desk in AMS to get boarding pass. Technical problems so not sure why. Very inconvenient. The KLM app is not as user friendly as most apps. Also had to wait almost an hour on the tarmac for a fuel truck, which caused us to miss a connecting bus in LUX.

The immigration hall in Amsterdam was understaffed, so passport checking was slower than it should be for a major airport. They need to get the automatic readers up and running for non EU passport holders. Waiting in line after a long flight feels a bit abusive.

Ad experience - been flying many years with them but they are losing out to other carriers with their service and bagage / seating policy. My 2 12-yo kids were not placed with the parent. Absurdity.

Our first flight was delayed so we missed our connecting flight. However it was easy to book a later flight on their app.

The service was great. However the lounge only gets passing grade

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

Cabin crew were excellent, very proffesional, polite and friendly, in flight snack was underwhelming, a packet of cheese biscuits, im sure KLM could run to a sandwich!

Check-in, boarding and the flight from Phoenix to Houston was quick and easy. The flight from Houston to Shreveport was delayed 5 hours. It was frustrating but I think United handled it the best they could.

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

In Liberia airport 5 min before our departure the airport was closed for takeoff for 30 min. Upon arrival to IAH we didn’t have any available gate and waited taxing another 40 min. As a result we arrived for 1+ h later. The walkway to the passport control in IAH is about 1-2 ml long. After the passport control you have to pass the security check again. Only 3 out of 16 checkpoints were open and the line was enormously long. As a result, even though we supposed to have 2.5 hrs gap in between the flights we missed our transfer. United rebooked us for the next available flight early morning and provided free hotel and meal vouchers through.

United is an incompetent airline. They parked the plane on the tarmac for an hour after arriving because they “didn’t have a gate available” it was actually some sort of lie because as we de planed there were approximately 9 open and manned and empty gates that we walked past. Many people on the flight missed connections for the hour long sit on the tarmac. Utterly baffling and incompetent behavior from United flight ops.

I boarded flight UA#1318 at Sacramento International Airport going back to Houston TX. The flight was scheduled at 5:10am. I was able to check in virtually using the United Airlines app. When I entered the airport, there was no one outside assisting with checked bags as it was for Delta Airlines. Immediately upon entering, there was a LONG, EXTREMELY LONG line to the kiosks to get boarding passes. I stand in line to get boarding passes then had to move to ANOTHER EXTREMELY LONG line to get my bags checked in. While standing in this line, we noticed an agent taking customers to 3 at a time to her station to check their bags in. Lucky for me, she called me back, checked my bags for me and I was on my way. I then encountered another long line at the TSA check and to avoid I ending up having to sign up for CLEAR to bypass it. So glad, I did.,...Both of my flights were great with no issues, butthe check in progress at Bush Airport was so much smoother. Check-in at SMF airport needs to be anaylzed and corrected. Do better United, I know you can....thanks

everything was pretty good. Houston airport is awful. Unnecessarily inefficient; people working there are rude. Badly run

Staff on board was excellent. Positive upbeat helpful- like it used to be.

The Sears in the 800s are not too good perfect Airbus why cant the new 737 fix that

Ot was overall fine. Left on time and had basic snacks. Weather was finicky but that’s not the airlines fault.

Even though we were delayed, we were able to make our connection

The flight crew was kind, flexible, and accommodating. The seats on the plane were extremely uncomfortable.

Check-in experience, for business call please provide a premium experience

Lost my luggage, ran out of food choices in business class, ground crew was completely unapologetic.

Excellent. The crew and flight were great. Checking in was easy and everyone was very helpful.

Entertainment devices on A380 need to be fixed, the seats might do with updates.

Everything. Employees offered to help me because I had to use a cane.

Check-in and boarding were great. On flight staff were rude and disrespectful. Paid for extra room and found it incredibly cramped. Bathrooms kept in poor condition. Overall negative experience.

Great seat in premium economy, great food and drinks throughout lots of in flight entertainment. 1 hour 40 min delayed flying out , 2 1/2 hour wait at passport control in tampa

Plane was extremely delayed, but not all of it was BA fault (some was). Worst part was lack of room - this had as much space as an Allegiant flight. I thought transatlantic usually gave you an extra inch or two, but not this one. Entertainment system sporadically worked and didn’t have great options. Overhead bins are old and tiny, not as good as aunties new planes.

My seat cushion was poor. The cushion was compressed and was uncomfortable for such a long flight.
