The flight attendants were friendly. I liked that I got a mini soda can, not just a small cup. No issues with our flight departure, etc.

The flight attendants were friendly. I liked that I got a mini soda can, not just a small cup. No issues with our flight departure, etc.

My wife and I had seats next to each other, but when our boarding passes were printed, British Airways had moved me away from her and refused to fix it. We tried to fix it at the boarding gate and were just told flatly "no". Never again.

The flight ran out of snacks before any was offered to me. Otherwise the flight was good.

Planes were on time. Pilot kept everyone updated. Crew was friendly and helpful

I had a horrible and traumatic bullying experience the last time I flew ( frontier). I was incredibly anxious about these flights. However, it was so relaxed, organized and the crew was efficient and polite. It was so refreshing and relaxing.

Didn't care for the crowding at the gate area at SEA TAC. Not a fault of the airline.

I have mobility problems and requested wheelchair assistance in Seattle and Anchorage and none was provided at all. Very disappointed. Only one gate agent in Seattle asked if I needed assistance boarding my flight in Seattle.... and only after three gate changes.... requiring even more extremely painful walking without assistance.

I recently flew with Alaska Airlines on a trip to Oregon and had a very frustrating experience that I hope the airline can learn from. I purchased upgraded seats with extra legroom for my flight, paying the additional fees for the comfort and space. During my trip planning, I called customer service to inquire about their pet travel policies and conditions, as I was considering bringing my dogs. However, I ultimately decided NOT to bring my pets and never authorized or confirmed any pet travel arrangements. Despite this, Alaska Airlines took it upon themselves to change my seat assignment without any notification or contact. When I arrived for my flight, I discovered that my paid upgrade had been downgraded to a regular seat - presumably because they assumed I would be traveling with pets based on my inquiry call. I hope Alaska Airlines will improve their communication processes and ensure that customer inquiries don’t automatically trigger booking changes without explicit customer authorization. Better staff training on distinguishing between inquiries and actual bookings would prevent this type of situation in the future. While I appreciate that the airline tries to accommodate pet travelers, making assumptions and changes without customer consent is poor service that needs to be addressed.

Flight was delayed and hour due to tire issue. First flight of the day, this issue should have been discovered prior to boarding.

One of the best roundtrip flights I’ve ever been on. We needed assistance for my elderly mother and without fail, each and every Alaska team member was helpful, kind, and patient. Will fly Alaska again and again.

They changed planes and the new plane couldn’t carry enough fuel to fly across the country so we had to stop in Kansas City to refuel. Flight was delayed .

Flight was too crowded and seats are too small, especially since passengrs are getting larger. Having a middle seat is ALWAYS tough! Woman on my left was large & kept creeping in to my space. Flight personnel were great! Have more savory rather than sweet snacks please.

Flight was crowded and the woman sitting on my left was large & kept crouching in to my space. You need bigger seats or smaller passengers to fit into the seats you DO have! Snack were OK. Would appreciate if airlines had more savory rather than sweet snacks, thank you!

Delayed flight (1hour) plus a long layover after an overnight flight with no backup plane available.

We were delayed, which I think had to do with air traffic control. Otherwise, everything was great.

The boarding process needs to be refined. Sometimes the gate crew calls out the zones and then flip to showing the.zones boarding on the gate monitor display. So, unless you are huddled around the gate lanes watching the monitor, you could miss your boarding zone. Suggest the zones be announced each time a new zone is allowed to board.

The boarding process needs to be refined. Sometimes the gate crew call out the boarding zone, and then flip to the monitor to show which zones are boarding. So unless everyone is gathered around to see the monitor there is usually confusion as wi which zones are boarding.

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

My issue was with TSA agents for delta airlines. My luggage got flagged. The agent was going thru another persons first. He took 20 min to go thru hers. I asked them to bring mine closer so I could sit down . They said you can go sit it will be fine. I said I am supposed to keep my eyes on my bags at all times. The agent was meticulously unwrapping 2 gifts that the lady had and then tried to re warp it. He was trying to be kind i get it but 20 min for me to stand watching him do that was ridiculous. It was 6 am and there were a ton of travelers. Mine was flagged for some air packed tea that I bought in Turkey. My previous delta flight and 2 others before didn’t flag it. Consistency would be nice. Also on the flight the window shades were down for take off and landing - I thought that was very odd I thought they had to remain open for take off and landing.

The flight was an hour and a half late departing which was inconvenient

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.

Flight was timely, relatively comfortable, with decent entertainment and food served. Only problem encountered was with the free messaging which I highly appreciate, but it did not work from iphone to non-iphones.

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.

The entertainment available didn’t work for anyone on the flight. Long 6 hr flight with no entertainment option and the staff didn’t know until an hour into the flight when we made sure they knew about it. They had no way to fix it.

Crew seemed a bit cranky. No seatback screens. But boarding was efficient and on time and we arrived early.

The worst landing I have ever had on a domestic flight. Thought we would lose the landing gear on landing in Newark. Then we spent 40 minutes trying to position the plane in the right place to be able to get the jet way to the plane. The plane arrived stopped. The announcer was that we were there. Everybody got up, then we were told to sit back down because they had to have us towed to a different position. We got towed and then everyone stood up and they told us we were in the wrong position to sit back down again, and then we got towed to a different position This did not happen immediately. It was 30 minutes while we wandered around a small section of the tarmac in Newark close to the gate, but apparently not close enough. Horrifying experience The CAB should be investigating that flight

Boarding was organized. Plane seats comfortable and service was attentive. Food options were good.

This was a very average flight. The seat was out of alignment so more uncomfortable than usual. The cabin felt not well maintained. But I safely got where I needed to go.

Trip was great. A wild landing in Ottawa with the wind and rain, but the pilot did a great job. Always love flying United.👍

I will never book a flight through Cheap fare. They booked me from Portland Main . And would not give me a refund, so I bought 2 tickets one for 299. From Portland Main to ORD. Then I had to buy a ticket from Oregon PDX to ORD that was another 440. So Just so you know they even told me it was there fault but no refund. Bad bussniess. I did inform United but they said they couldn't help me due to the fact I booked through Cheap Tickets. Never again. And I'm spreding the word. I let everyone know at my 50th class reunion
