Airline reviews

Horrible I am at almost 2,000,000 miles on United. This was probably the worst flight ever. An hour and a half before takeoff I get a message that they’re changing the plane and I no longer have a seat in Polaris business Supposedly, there was a problem with the plane, but then there was no other plane Finally, they decided to bring a plane from Newark to Washington Dulles Of course the original flight was at 10:45 PM so by the time the plane got there it was 12:30 AM. It had not been cleaned. It had not been catered. They don’t really have people available to do those things when it’s not pre-programmed at 1 o’clock in the morning. The crew had to be changed And the new plane held 28 fewer people than the scheduled plane There is no way you can hate United Airlines enough The people at the gate were actually just fine, but it was management who was completely useless And did they send extra help to the people at the gate? Did they send supervisors? Of course not. Just don’t take United find somebody else or buy a boat

I flew from Barcelona to Chicago on UA yesterday. The flight was on time, the pilots did a great job and the flight attendants were super nice. All of them. Also food was good, and the drinks, including wine were served a few times during our flight. I highly recommend this airline.

There were no facilities in the middle of the aircraft and premium economy was not allowed to use the business class facilities, and had to share the only two toilets at the back with economy. The upgrade to Premium was definitely not worth it

When I went to check in at the United counter in Barcelona, Spain I had 2 different menat 2 different times in United uniforms (standing around with a couple other employees) ask me if I was traveling alone. The one man asked me 3 different ways if I was traveling alone. I am, 68 yeaers old and have all my faculties. I thought it was weird and it made me feel very uncomfortable. What difference does it make if I was traveling alone or with someone? What if I was a recent widow? That would have been horrible. They never gave me a reason why they needed to know who I was traveling with. I was hesitant to question them because I needed to be on that flight.

I really enjoyed flying with United airlines amazing experience , good customer service and great food

The first flight was an hour and a half late leaving, thus missing my connection. The second flight Departure was two hours late Leaving.

The width of the chair is very small. Not comfortable at all.

No entertainment system or wifi on a 12 hour flight. They failed to include GF meals And snacks as requested on my ticket so I had very little available to eat. Crew seemed indecisive.

one hour to board connecting flight from frankfurt trying to beat the far Z gate and with immigration of USA ppus waited for delayed boarding in gare for an hour and fly half gour late worst transit im frankfurt this airlines are for profit passengers are victim of dysfunctional airline frankfurt so crowded restroom are too small

Seats were very comfortable and everything was in good working order. Crew was disengaged to the point of being rude.

Better leg room than expected in economy. Nice crew. Adequate bathrooms. Seat cushions a little thin, but recline well and have adjustable headrests. Best value. Liked having nonstop from ORD to Lisbon.

The food left a lot to be desired. The crew was great

The cabin crew were curt, not with me, but observed with other passengers. They were unduly rude and it was unprovoked and when they realized they were wrong, they made no attempt to apologize for their own confusion.

I was disappointed of the crew, not friendly and attentive. Delay one way for fuel leakage and the plane is so hot. Not that great all around but I’m glad I experienced it so now know better.

I like the price. I dislike the website where I wanted to ask questions about the unusual high prices of the luggage fees. I called the toll free number from the United States and I cannot get through. You should test your own toll free website for info and you will know what I am writing about.

I’ve never had worse food in business class ever!

Baggage check in was very slow. No sign that the check in was TAP until the station opened. Understaffed and overworked team.

Flight delayed by >1 hour. Long boarding involving riding a shuttle to the plane.

Larger seats on this plane made the ride reasonably comfortable. Our next flight, from Lisbon to Copenhagen, was inconsiderately tight and stressful. The seats were smaller, space between rows was very limited (no button or mechanism to even slightly incline anyone’s seat), and leg-cramping under the seat in front. Just like sardines in a can. Really felt for all the tall Danes on the flight. Their knees were pressed against the seat in front throughout the flight.

Packing people into a bus like sardines and then making them wait for at least 10-15 minutes before driving them to a location a mile away is not the way a national airline should represent itself. And it seems like everyone chosen for additional screening was a woman. What is up with that?

Never took the flight due to strikes which happens but there was no timely coordination to find me new flights. I had to call Lufthansa and Kayak support only to be given no good options and a 75% refund. Ended up spending way more for alternative flights that I coordinated myself for a trip I had booked 6 months prior.

Come on. A two hour, 7am flight and a small bottle of water and a tiny chocolate bar was provided. No coffee, no nothing. Poor.

The United flight was excellent! The flight attendants were attentive and nice, and the food was very good! And the glasses are larger than on Lufthansa flights! I don’t want to have to ask for 15 glasses of water because their glasses are ridiculously small!

Plane was crowded, seats narrow, legroom nearly nonexistent. The entertainment feature didn't work for my row and nobody was able to/interested in trying to repair it. This flight was in direct contrast to a very comfortable Lufthansa flight from RDU to Frankfurt about a week earlier.

Rushed due to connecting Lufthansa flight delay Seating very tight and uncomfortable with poor leg room Long lines for rest room

Better when flight announcements are better produced and slowed down a bissele

My only complaint would be that we paid for insurance in case we needed to change our flights. However we still had to pay to change and was not helped on either travel parties. I would like a refund for my change fees as indicated in our insurance plans.

Le personnel attentionné et trilingue, la tranquillité du vol. Aucun aspect négatif

The only really annoying part was the TV screen. It was kinda messed up. Like it would just randomly turn off or switch. It was also not responsive. Which gets annoying on an almost 12 hour flight

Luftansa over booking canceled my flight 2 days before I left, so I called to reschedule but didn't answer, so I had to cancel. This has ruined my vacation plans and I already had to pay 3 days for a hotel reservation in Barcelona. I don't think I'll ever book this flight again in my life.
