The food quality sucks. One must starve if they do not eat flesh Or wheat based products Some variety would be expected. The trivial amount of snacks and or food is inhumane

We Left Calgary 1/2 hour late and that made for a tight connection in Denver. After arriving everything was done to help us make our connection. That was a great effort. Thank You United

Efficient all round, very good crew. Short flight so the food, of course, was just snacks

Overall, it was good. I was seating next to a wonderful lady and did not notice how time flew. Thanks

My flight was delayed about 1 1/2 hours in Chicago, but other then that it was a good flight.

The experience was great, the crew was very polite and hospitable. I will definitely make if my go to airlines.

It was all good flight was on time, service was good I enjoyed a few movies and everything was smooth

Efficient, calm when things were delayed and kept us regularly informed of what was happening.

Airbus plane, nice and polite staff, entertainment even as it was a short flight.

Very nice and clean plane. Transit time between flights was tight though

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

Snacks were just placed and many people were hungry and unaware they were available. Ran out of water bottles. Attendants not available. Missed entire meal.

Very Bad experience with Swiss, they robbed me for additional baggage and misguided. The flight was delayed for 2hr 55 minutes, screens were not functional and food was also bad.

The free Wi-fi for Aeroplan members was a great touch. The time passed quickly. I found the seats seemed a little closer together than I remember. Not Air Canada's fault, but we were about 20 minutes late landing because the airport was too busy. We had to circle around for a while. The boarding and disembarking went very smoothly.

Too many delays. Seats too small. A budget airline. Will never fly Air Canada again.

On board wifi or other entertainment. Landlines option was good but ran late to Pearson

Extremely turbulent landing. Crew was friendly and plane comfortable. Airport and US pre clearance was understaffed

More space on a sold out fight and food trays were dirty

The airplane is way too tight, you can hardly enter into your row to sit.. more like kids seats than adults.

My original flight was cancelled -- but I have to mention the excellent service I was given by the agent working at check-in who found me an earlier flight -- and helped me navigate security, ensured my baggage kept up with the quick check-in and boarding process -- and just generally made the re-booking process a breeze. Thank you! On flight was fine, but we unfortunately meant no in-flight service -- no water, or coffee (it was an early morning flight...), but the crew was pleasant and accommodating throughout.

No in flight entertainment on a 750 mile flight. Made you join their "program" to get it. It was free on my first leg of the flight from Cincinnati to Toronto. In addition, there was brief period of turbulence that prohibited the crew from serving refreshments. They used that short interruption as an excuse to never serve drinks at all. They had ample time to do so and chose not to. They went around serving half cups of water instead rather than have their carts in the aisle with drinks.
