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

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.

The plane was ok, I was in business class and was surprised there were no pods and each seat was right next to another one. That said it was comfortable and the food and coffee were good. Entertainment wise again I was surprised to see only movies and no TV shows. Check-in at Toronto Pearson was an absolute disaster, which was especially disappointing as I was a business class passenger. There was no dedicated staffing for the business counter and four (4) airlines employees assisted one economy class passenger for about 15 minutes when one could have easily assisted me. Overall room for improvement, particularly in the on-ground experience and airplane infrastructure.

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”

I had a memorable experience. I dont have any comments at this time regarding waht could be better.

I have my baggage left either in Jeddah or Addis and undelivered to Abuja

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.

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 hardly ever changes Videos not often updated for often travel.

Traveling with Ethiopian is always a good experience. I also enjoy the stay at skylight hotel in Addis

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.

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.

My luggage did not arrive yet, it been 4 days without any information
