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.

Better WiFi. I cannot understand that in 2025, United is so behind on a technology that is now a necessity and still painfully unreliable, slow and keeps disconnecting.

Great service on board. Boarding a bit slow due to process. Food was pretty average.

Very small cramped plane for an international flight. Everything else was good, but it was maybe the smallest comfort-wise I've ever been on for longer than 3-4 hours and the trip was 7.5

This flight with a lot empty place , and I have more room, feeling comfortable.

Super experience. Earlier than schedule departure and arrival. Baggage handling was very good

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.

The cabin crew was professional and there were plenty of movie choices, but the food was a bit sub-standard.

Plane left an hour late, I missed my connection and my bow case was never even loaded on the plane in VA. I deal with this type of nonsense everytime I fly air canada.

Check in agent was very helpful and polite. He helped me board the earlier flight back home instead of waiting 2 hours at the airport for the next flight

The flight was delayed an hour, but not because of Air Canada. The crew was polite, professional, and competent. The food was above average for Air Canada, but just fine. The stand out for me in the 10 hour flight was the entertainment package. The best of any airline I’ve experienced so far. Looking forward to my return flight to finish some more of the shows I was watching.

Very good!👍!especially the typhoon coming, the speaking Chinese language service is excellent 👍!

Not to out myself as both a child at heart and kind of a terrible person, but the Pokémon safety video was the first time I watched an airplane safety video in like a decade. It was ADORABLE!! A great way to encourage attention from young and old alike.

Seamless! Long but the seat back entertainment kept us all busy the whole time! Meals were excellent! Crew fantastic! Very attentive!
