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.

Typically good service onboard but baggage delay in airport was significant

My, Syed Zawar Hussein Shirazi frequently flyer membership number was not included on my boarding pass from O’Hare to Istanbul despite my reminder to the attendant at check in. Further she forgot to give me my boarding pass form Istanbul to Lahore and she needs to improve her customer service, please 🙏

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.

Flight from London was delayed so missed the connecting flight. Taking 2 days to get to destination which should have only taken a few hours.

Too cramped up for the better seats I paid for.

I didn’t like my seat in my return flight from Montreal to Orlando at all; considering I paid extra for better seats. That middle seat was cramped up way too much.

Suitcase didn’t arrive to Stockholm. Chairs y comfy and not even water is offered

Bad baggage and people management at boarding forcing me to dispatch my bad despite being the perfect size and respecting everything perfectly, whereas many did not and many free empty spots on the plane as usual… making me loose time and my planned bus at arrival to go to Geneva. Costing me 100 euros extra! So Brussels airlines needs to refund me

I never board the flight. My visa was delayed and when I tried calling Kayak, no one answer and I still have not heard from anyone.

All great. Very efficient. Good emails that kept us in the know

Original flight was canceled, booked another one and find out when checking I was on the waiting list. Horrible experience

Actually this is my first time using airline I was in every single thing that happened throughout our journey, the appearance of the plane inside furnished about the seating the flight attendants and many many more I was so excited throughout thank you Brussels Airlines for the great service.

On board service was decent. I like the legroom at UA that seems to be more than in other airlines

A bit chaotic boarding flight but over all good experience.

The crew were amazing. They should improve the inflight entertainment

The crew was unfriendly and very rude to name a few (Helina). I felt unsafe due to most of the cabinets were open while on flight. All in all the flight was ok, but the crew needed more training on customer service most of all for international flights.

Delay not posted, only departure time listed- not boarding time. We left an hour late and arrived 45 min late. Restrooms had backed up sinks and toilets not flushed ) passenger error). Lots of screen for entertainment didn’t work. But we arrived with our luggage

The plane was old and the luggage racks above us were visibly shaking during turbulence. Water was dripping on our heads during landing. Our flight was over 2 hours late departing but we were not updated or told what to expect as the screen at the gate continued to read “on time”

Check in took over an hour because printer was not working. Attendant did not know how to give free layover Addis Ababa hotel vouchers or update frequent flyer number. After repeated attempts, got voucher emailed. However hotel wanted printed voucher hence more delay. Bus time from hotel back to airport was printed 4:50 hours, but hotel reception called at 3 pm saying bus will leave at 4 pm. Then hotel reception called again saying 4:15 pm. We rushed at 4:15 pm and bus was not ready until 4:40 pm. Many audio outlets were not working in planes.

Our first flight was delayed and when we got off that plane, nobody was really helping to direct us to the next gate. It was very frustrating. One staff simply said hurry, which wasn’t helpful. We had to go a long way to get to the next gate. Another issue on the plane itself was the bathrooms were disgusting and filthy and it didn’t seem like anybody was checking on them were cleaning them and it was a long flight. There was urine on the floor and they stunk. Also, the screen in front of my seat did not work, and I tried different headphones and still had no sound. You would think somehow those things are reviewed occasionally for working order.

My recent experience with ASKY Airlines was disappointing. The check-in process was disorganized, and I was provided with inaccurate information regarding baggage requirements, resulting in unforeseen expenses. Additionally, the ground staff demonstrated a lack of professionalism and appeared insufficiently trained to handle passenger needs effectively. Regrettably, this initial encounter has left me reluctant to consider future travel with the airline.

POSITIVES The hostesses were mostly pleasant, NEGATIVES The full flight wifi was horrible, hardly able to use it. My charger port was not working which made me use my neighbour's port which resulted in an accident which ruined her flight. During dinner, meat ran out when the cart got to us forcing us to eat vegetarian which was not great. We watched everyone around us eating meat. My wifi did not transfer to the second leg of my trip as they promised as they changed the plane. I was thrown off the window seat I booked for the 2nd leg of my journey as they changed planes, all done at my expense. This was not a cheap flight ($2600) which i hurriedly had to book to attend my mother's funeral who passed away suddenly. I was honestly disappointed with the whole saga as I heard Ethiopian Airlines was one of Africa's best.

The food was terrible and the seating was uncomfortable, but the airline did a great thing letting us board in Abbis Ababa on our connecting flight after our original flight was very delayed.

Food quality was low for business class. No snacks between meals. Very confusing “One World” participation. This airline seems to be part of the program but doesn’t recognize the benefits to customers (luggage allowance)???

Due to the operational delay with Southwest, I missed my connecting flight in New York. Southwest rebooked me with Turkish. Southwest paid for my accommodation in NY, but did not provide food at the hotel. I ended up spending 34 dollars on my dinner. Moreover, in Istanbul, where I transited, I had more than 10 hours of layover without access to the Turkish Lounge. I spent 117 USD to have access to the Yotel cabin for only 4 hours of rest and recuperation from jet lag. This was the most painful trip I have ever had in my life.

Cancellation was really bad no organizations at all and I want to choose a direct flight for the 18 January counter agent does not allowed me no even to speak was rude I was forced to got a third world country flight

There is nothing Royal about Royal Air Maroc. Old planes, poor service, no entertainment and everyone of my 4 flights was late.

There is nothing Royal about Royal Air Maroc. Old planes, poor service, no entertainment and not one of my 4 flights was on time.

Good! except for the in-flight announcement which was very poor. The flight attendant was inaudible with her english language throughout the flight. Her communication was bad, very bad. I could not fantom what she was saying in english and she was very fast you could hardly hear or understand what she was communicating. She needs to improve. Thx

Improve food quality and clean the seat . Bathrooms not clean

I had pre booked gluten free as a meal preference. Nothing of that was considered during my flight. The attendant said he had no idea and would check but never returned with a response. I did not eat anything that flight and was super hungry

Stay away at all cost! Late boarding, late departure, inoperable seat controls and entertainment screens, very rude cabin crew,

The flight itself was fine. The flight was delayed for nearly 10 hours and there was inconsistent communication about why it was delayed.
