Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

Was happy we finally got upgraded in 1st class. The seat getting old. The cushiness need some improvement.

Ineffective communication with United resulted in lost baggage. Their Baggage Tracing counter at MUC was shut down from 11:00-14:15 on my arrival. Undertrained, underinformed staff had me Running all over MUC to find someone to help me to no avail. Staff was rude, unhelpful, and unable to effectively use the systems they did have operational. They refused to contact United in any way or provide any accommodation or other resources while I waited for my luggage. This has destroyed my downstream itinerary. If they had even the slightest visibility I may have been able to reschedule/plan, but again, their staff provided nothing, and did nothing more than their website, which doesn’t even work on a standard phone browser. Miserable failure at all levels that weren’t associated with the operation of the aircraft.

Sat next to a one year old. She crawled all over the place and made me laugh.

The Crew and the food was the worst I ever had in Business Class. First they told us there were no space for carry on. It was plenty of space over our 2 row seats, we had to ask to let us travel with it which was accepted. They were aware that we had to run for the connection due to the previous flight delay. Have us one hour waiting for more customers and not even offer a glass of water. Then started the service and they started to serve other passengers drinks in business and did not offer any drinks until they serve our pre ordered meal and I ask for something to drink. I had to wait until they finished to serve all passengers until Inget something. The crew was the worts I ever had for Business Class in my life.

Not great experience - we were super late boarding due to issues with aircraft. Then when we finally all got onboard and seated and they started taxiing out to the runway they just stopped then turned around and went back to the airport. Apparently the crew “ran out of time” to legally fly us. They mentioned that they were about 2 minutes away from taking off. I understand the rules and safety but kinda wonder why they would have bothered boarding us in the first place? Had to go all the way back and de plane and then wait in a HUGE line to get a hotel (this is somewhere around 2:30am) finally got to hotel by Uber (no shuttle after 20min so gave up) and they ended up putting us all back on the same aircraft at 10am next morning so got about 2.5 hours sleep. They did give us. $250 credit, but it was a São Paulo Brazil flight out of Dulles. The flight and everything was fine.

Starlink wifi on the Embraer E175 is an excellent experience. I was able to connect and work from IAD all the way to approach into BTV.

7 hours delayed due to operational issues on United’s end. Basically laziness.

Short flight but an "eager to help" crew made the journey more enjoyable!

During booking, I kept trying submitting my payment from the Mexican website and it didn't work. After I had the idea to change it to the Canadian website, it worked but I had to be charged the equivalent of 50 CAD more. I received the clear instruction that I would only be able to check-in at the airport and that it was impossible to select a seat 24 hours before departure, that I had to pay 144 CAD to do so, although not only was I able to check-in 24 hours before departure, but I could have selected my seats for free then. All in all, I almost threw $200 out the window due to misleading information. Besides, the app kept crashing, the information to get to the gate on the app was inaccurate, my gate was switched and I was only informed once in the air (luckily I had noticed the departure pannel), I was not addressed in my language beforehand and even if I tried I was immediately answered in English (which meant the crew understood but didn't want to answer accordingly), there was only one snack & beverage service on my medium haul flight and no beverage service on my short haul flight. To be fair, the planes were comfortable, the crew apart from the language issue was helpful, dynamic and engaging, the plane was clean and the directions were clear and direct. United has a lot of potential to be one of my favourite airlines, but the devil is in the details and a lot of them missed the target.

Everything about that day was great I was happy with how things went as a first time traveling with the airline thank you for all that you’ve doing by taking us there to our various destinations thanks.

They oversold the tickets by one which was my ticket so I didn’t have a ticket till last second

Not good. I was supposed to be in Mint but got in economy class

Service was slow and checked bag was off last evening when flying business

Turkish Airline canceled our tickets in the very last minute, with our luggage and everything else, all prepared and good to go. It’s clear that they sold the tickets for better money to someone else. Bad, Bad, Bad business!!!

Awful seating. Bad food. Staff only have one bottle of water and no cans.

it was like a banya -so hot... They did provide a great experience with special food. one toilet broke midflight In general it was a peaceful and relaxing flight - for business class it was good.

Chicago to Istanbul was a much better experience than I expected since I’m more accustomed to Qatar Airways business class. The business lounge in the Istanbul airport was amazing - loved the lockers and phone charging stations, and the bathroom was a spa experience in itself. The onward leg from Istanbul to Karachi was utterly disappointing. Terrible plane, and I felt like I was in economy - the seats don’t come near to lying flat and the food was mediocre. What a sad downgrade - it isn’t as though the ticket on that leg was cheaper. So, on that front, there’s no contest with Qatar airways.

Second leg of Turkish Airline with Indigo is disaster for following reason. 1) You have to carry your cabin bags through ladder to boeing 777 because it was parked somewhere in parking lot and was not given a gate to board passengers and this seems to be people traveling to and fro from those flights and is not issue with flight itself. 2) I choose non vegetarian food on Turkish portal way ahead of checkin to entire trip, However the Indigo flight gave me random veg food saying they code veg food code from Turkish. 3) Indigo did not served any alcoholic beverages stating some weird reason which is non nonsensical. 4)Indigo have TV screens in front of you but it displays nothing except "Welcome Onboard" with annoying white black ground in dark flight. This is the most stupidest and annoying part because you are held hostage for 7 hours and only thing you could do is stare back at white screen which does not have entertainment package or even flight tracker. Such a shame.

nice and clean plane but the seats and the comfort was not what i expected. i expected more based on all the ads and reviews that i've read. I guess you get what you pay for in economy.

Missed it by a couple minutes and couldn’t find an alternative flight so had to spend the night in DC and after much shuffling from 1 airline to another managed to get a United to Frankfurt.

There were only 2 toilets and one of them did not work in business class. We are not allowed to cross classes so had to wait in line to use the toilets!! The entertainment touch display was finicky and did not work all the time.

We missed our flight. There was not enough time built into the layover to get through immigration, customs, bagclaim, bag rechecking, and the long trip to another terminal and gate. Kayak really screwed up. We took the bus up to Wisconsin and then were picked up in Brookfield by private car. It was lucky we didnt miss the last bus out.

I tried both on line and by calling the Customer Service line to arrange for a special meal as i have food intolerances. I was under the impression from your service representative that I was successful. I was not. I cannot eat spicy foods and get very ill if i eat bell peppers. I could not eat either menu choice and no special meal was actually ordered. ( your representative tried to order it for a flight that did not have meal service!!! - found this out later). Your wonderful cabin crew managed to put together a fruit, salad, roll and cheese tray for me so I had something to eat. WHY WOULD YOU SERVE SPICY FOOD, WITH NO MILDER OPTION,ON AN INTERNATIONAL FLIGHT???

Crew was professional and great, flight was clean. However food was pathetic. I ordered a Hindu meal assuming no meat but they served chicken. Need to be very specific- Hindu meal should be categorize as Vegetarian - no meat or egg. Or it should be specific that we are serving meat.

Late flight Delays Poor service Poor staff Worst airline ever

Ground staff and cabin crew were excellent. Flight was perfectly on time. Zero issues.

Even after a delay, getting off the ground, thanks for keeping me safe, the airline made certain that my connecting flight was rebooked to get me to my final destination. It was actually rebooked twice, and my luggage still managed to meet me. The airline gave me a credit for food and beverage to be used at the airport vendors, regretfully, the credit did not transfer to my final boarding pass. Oh, well…

Trip was smooth, good drew, average meal, almost cold coffee. Excellent landing. Did not enjoy going down the stairs, walking to the gate, walking up the stairs, going a long walk to the exchange gate, and going down the stairs again to be bussed all the way where we originally landed to take our next flight! Over all an average experience. Thank you.

I booked extra leg room, due to seat neighbor i now consider extra shoulder and arm room as well. Seems like the seats shrink in width now The crew was very friendly and professional ( 100%). Food was good not great, breakfast was bad, a dry slice of bread would have been better. Facilities clean.

Overbooked. They left a lot of passengers on the ground

My seat was broken and ducted taped and my monitor did not work the entire time over 8 hrs sitting. And I had no books or anything with me

Good with timing of flights. The crew was exceptionally unfriendly. I heard more than one person say this. And even with the aisle, it seemed more uncomfortable than usual. The movie selection was old and poor, but the dinner was great - the lasagna and tiramisu.

Poor. The airlines left my luggage in Miami. It took 2 1/2 days to get my luggage at my destination. I was forced to buy clothes and daily items for days. There was little concern to get my bag to me which highly impacted my trip. Seats were cramped as well. Would not recommend this airline to anyone.

The check in process is chaotic. It says partially checked-in. Never heard of such a thing. Then lost our reserved seats when we finally checked in at the airport. The seats don’t recline. Then we had to get mew boarding passes at the connection. Last, my companion lost her baggage and up to now there’s no update. We’re already half-way through our vacation and still no news what happened to the luggage.

This was our return flight. It was slightly better than the one we took to go to Rome, mainly because the food was slightly better and more abondant. On our LA-Fco flight the food was way below average. Also, it felt like the legroom in Economy was smaller than other airlines we used in the past - my knees were touching the seat in front of me.

There was so little leg space in middle seat that the blanket/pillow accessories and my feet could not fit. Knees were 1 inch from seat in front and when person in front reclined, it was uncomfortably invasive in my space. I am not large, 5’5” and 130 pounds

Wonderful! Everyone very helpful and kind. Returning flight was cancelled but rebooking was easy.

Flight was on time, there were no issues. It was also direct to SFO. For an international flight, I call that a win.

On both sides of my itinerary, the planes were old, the seats did not work, the seats were filthy, and the crew were unfriendly

The issue was not with BA it was with the link yoiu sent fopr booking the flight

Loved the boarding option from Business class lounge, experience on flight was excellent, plenty of good food choices

Getting the boarding passes between the BA and AA apps was very clunky.

The airline was not clear about a new departure time so we got to the airport early anyway. The flight left early which was great because of weather. The check in process was very easy and staff were friendly and helpful. The crew was great and our flight was very good.

Awful it always is unfortunately is the only way to fly direct to london

I travelled in business class and was disappointed by lack of service, curt and borderline rude time of the crew and to top it off, all of my luggage was delayed. It was like pulling teeth to even report the missing luggage and recover it the next day from the airport.

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.

Boarding was poor. All groups called immediately one after the other resulting in a long queue in the jetty/jet bridge. Seats were very hard and and did not recline on a 4.5 hour flight. No food was available. Plane was cold. There was no entertainment.

The cramped seats are cruel and unusual punishment and may violate the Geneva code.

Check in was was and the agent was very friendly and helpful The lounge was nice...boarding was straight from the lounge Everything worked at our seats, and video entertainment was good ..food was mediocre
