It was fine, definitely older planes with no charging or anything. There’s no entertainment set up on board, but it is nice that they allow you to access the in flight entertainment from your phone without having to pay for the Wi-Fi and they do offer free texting.

It was fine, definitely older planes with no charging or anything. There’s no entertainment set up on board, but it is nice that they allow you to access the in flight entertainment from your phone without having to pay for the Wi-Fi and they do offer free texting.

I liked that the flight was nonstop from ORD to CIU for $200 round trip.

All flight attendants could benefit by taking an international flight on Qantas Airline. Qantas attendants are much more hospitable in every way. Much superior than and attendants on any US airline.

While the staff was pleasant and helpful, the following observations are for your awareness. There was some delay on the tarmac on take off and landing. The paid lunch/food offerings were limited. Entertainment was only available on WiFi at a cost.

The first flight was better in terms of the aircraft.

So far so good but food and entertainment are not available for this flight

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

Overall poor for me I paid extra for seats with leg room and my regional flights exit row seats have less leg room then the others that's money that could have been saved and on my final flight home the flights air was not operating it was unbearably hot in the cabin I will be contacting United and filing a DOT complaint

It was my first time with United Airlines and I would say it was very good experience and best of all the flights were on time. Will definitely fly with United Airlines next time.

Very modern plane. Good seat spacing. Meals were good. Screens had tons of movies and worked

You get what you pay for. In general I like the service and flight attendants.

Excellent! Outstanding customer service, the best service I have received. Food was served, dinner, snacks, beverages, crew was there to greet you. 10/10

Charging $300 to be able to pick a seat next to your wife was nothing less than extortion.

My carry-on bag was taken from me when I boarded. It was checked through to London at no charge. It took a big of shuffling, but I was glad not to need to mind it until baggage claim.

Great to have power available for every seat in Premium Economy. I do wish the WiFi was less expensive. It was 23-24 Euros for the flight for one device. And there were times it was unavailable.

I’m very mad because I paid an extra $105 to change seats to an exit row with more leg room. The app clearly showed a gap in between the seats in the row I changed my seat to and I paid for it. When I boarded the plane, it wasn’t an exit row seat and no more room than my original seat. I feel like I was ripped off $105.

The crew on AA international flights in my experience are generally lazy, rude, and inefficient. These guys did not disappoint.

I had a great experience , crew was great and enjoyed the entertainment options I will be booking my next International trip with them .

Front desk was closed at 6 pm, I was unable to get my boarding pass and as such missed my connecting flight home.

I wish they could put the pre-tsa check on the tickets or global entry.

The crew was the best I’ve ever encountered. Business class was spacious, immaculate, and very modern.

I wish seats were not reclinable. It's so claustrophobic when the person in front of you spends most of a nine hour flight leaned all the way back. The crew was really nice though and the dinner (red Thai curry) was pretty compelling.

Our flights were severely delayed, then canceled and we had to fly out next day with no sleep accommodation help. This led to our baggage being lost and the service reps after baggage couldn’t be bothered to help. They kept sending us to different counters when we were at the right counter to begin with. The only saving grace was the angel woman supervisor with blond hair who helped us put in a missing baggage claim.

The boarding system was all bogus - employees at the boarding gate were not sound like proffesional or may be possibly rational

I got an email in the morning of the flight 1/7, from Kayak, that I was rebooked from UA 906 to LH 430. Nobody at Lufthansa ot United knew about this. I went to both counters. at the airport. Also, Cheap Flights, who I booked the ticket through, did not know. I ended up staying on the United flight. But this was very disturbing, since I got a very late notice that I was rebooked to an earlier flight, I hurried to the airport to find out after a lot of inquiring that this was a mistake. Not a good Kayak experience.

After living in Europe for five years and flying with Lufthansa and KLM airlines, I’ve realized that United Airlines is now a budget carrier. The flight attendant are not friendly. The seats are not comfortable. And everything comes at a cost. I will be flying with KLM and Skyteam like Delta to the US going forward no doubt. United Airlines is not what it once was:

Delayed take off but I think they waited for passengers.

I had to fly United where the flight crew was atrocious

Flight was delayed for no reason and I missed my connection. This added another day of travel and I missed an event I was traveling home for.

I traveled with my sister, however ,we booked a flight separately, and we don't sitting next to each other. The staff on the board where on the top of this unit they find us sitting together. Ty lufthansa team. U are the best

Boarding was chaotic. Service was poor. Attendant was slow and rude. In business class, I was not offered a drink until 1.5 hrs,after takeoff. Food was inedible.

Great crew, newer plane, boarding was very disorganized, I still don’t understand why airline keep boarding front to back for coach instead of back to front

Paid for a seat I didn’t get. Flight attendant said they would “report “ the problem. Food terrible. No service unless requested. Plane filthy. Seats falling apart. Broken footrest. Bathroom toilet held in place with tape. No gate announcements though delayed 2 hours. Is that enough?

I don't like anything in this flight the food was bad the service was bad the flight was old and not connected to the screen no intertainments at all and it was long trip was bad intertainments the crew not helping

The flight was great. I don’t know about the food because I was asleep and they didn’t leave me any.

The flight was great, smooth and even a little ahead of time.

There wasn't a time for neither food morning entertainment in a short one hour hop over.

Not online or self check in, sent emails in Italian language ,not recommended.

Premium Economy was average for class. Seat comfort was just okay. Crew was attentive. Checkin was fine and moved quickly. Boarding process in Rome was not well organized.

It was horrible the woman next to me was sick and I asked if they would change my seat and they said that they didn’t have any available. I sat next to this women for 9 hour and now I am sick .

Better synchronizing the boarding processes. The audio announcements, the personnel and the digital signage were not saying the same thing. All confusion.

The first class seats were unusable, mine at the end of the flight, my husband's in the middle of the flight, and the one next to me was unusable either, they had to move the person to another seat.

Last minute gate change. Didn’t put our TSA global on our trip even though we asked multiple times to confirm. Did not help with food when could not eat what was served.

Our luggage didn’t arrive with us, that puts a damper on the whole trip.

The cabin was bit colder than I like but the crew members looked after us very well. They did even offer hot water bottle and hot chocolate. I cannot rate the crew enough excellent is not good enough. They really were wonderful.

Boarding is always a challenge as folks in al groups crowd around for no reason, but crew handled it well. I once again applaud the LHR ground baggage staff as they got our bags from a flight at Terminal 5A to a flight in Terminal 5C within 40 minutes...amazing!

This flight from London to Chicago was actually on an AA airline. I did book through BA but the flight was AA. Great flight, hectic in Chicago, I wouldn't choose to fly through Chicago again, but that's not the airlines fault. The flight itself was great.

Push back is not working when I complaint a male staff he told me that most of the seats are like that so we can’t do anything

Seats were way too small. I got claustrophobic waiting for trash from meal to be taken away. I couldn't move to even close my tray until trash was taken.

Was 3 hrs delayed and my poor friend I met in Barcelona was waiting at airport for 3 hrs. Dallas airport was awful
