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

Flight was delayed 3 hours. No food and drink vouchers was provided. They offered a mini pretzel bag and water .

Staff was rude. Didn’t give water for 2 hours. Worst service

Was on time until within 1 hour of flight-how does that happen? Staff very friendly.

I liked the choice of lemon ginger tea. I think stewardesses can be more considerate of older people needs.

Flight delay was communicated before leaving for airport which caused it to be a non-event. Great flight and crew!

Wish a flight with more than 2 hours with some snack rather than just cookie/biscuit.

The flight attendant, a black woman with curly hair who sat near Row 21, was wonderful and kind.

Flight delayed and missed connection. Rescheduled flight cancelled after 6 hrs wait. Rerouted thru ORD, flight cancelled, overnight stay in ORD. Still in the air on new flight!

Delayed delayed delayed and no offer for food or vouchers

A couple ladies from the crew were so rude and nasty. Thought they were mad at having to be there especially if you asked a question. This will make me think twice next time if I book a flight with you.

Always seated jammed in rear of aircraft Admirals Club food at DFW terminal D was absolute worst food experience and I pay $600/year to eat this dried out junk

Flight attendants on this flight were very attentive and friendly

You can plug your phone in & use their wifi to watch movies, etc, but the plane’s wifi was disconnected for most of the flight.

Very below average , plane from Dallas to Toyko was very poor designed plane. I had to sit for 13 hours next to fat man. Really bad seat and entertainment screen sucked
