On time flight. Seat comfort could be better in the Comfort section.

On time flight. Seat comfort could be better in the Comfort section.

My only complaint on any flight is meals but your gnocchi was good. The worst is breakfast. I can’t understand why you don’t just serve something simple like yogurt, fruit and a muffin or cinnamon roll.

The staff and the boarding procedure were all amazing . The one flight was not equipped with WIFI which now adays seems odd. All in all the experience was good

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

It was beautiful easy and smooth experience. Thank you. Will definitely get Delta for my next travel.

No one fussed at me about my pap machine as a 3rd pice on the plane. Boarding was pleasant and smooth. The boarding agent in Anchorage was a fun character- he could be in a movie. :~) The on-board crew were downright pleasant. No militant attitudes on Delta. Like all planes these days the seats are too narrow for standard Americans and at 5’2” there is barely enough leg room. I don’t know how tall people fold themselves into the seats. But that’s nothing specific to Delta

Excellent flight, the planes were newer, they did a nice job with boarding, great service overall.

Delta is better for short flights and very low need for customer service. Avoid for longer flights

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

Delta is a premier airline so my expectations are most always met.

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.

We were given vouchers we couldn’t use with a 5.5 hour delay

I fly UAL 7-8 times per year. This flight was not up to snuff because it boarded very late "due to unexpected delays in restocking the plane" and yet Flight Aware showed the plane had landed some 10 hours earlier--so I think they could have planned accordingly. The FA's were nice but harried. The video system had to be rebooted 3-4 times. The food service was rather abrupt; they forgot my row and when I asked for my meal, they brought it with some impatience. Overall, the flight was fine, but the little details made it feel somewhat mundane and hurried.
