An entire day of delays. Cost lots of money. Meals and a hotel.

I appreciate the staff who allowed me to board though I arrived a little late! Regarding the assigned seating, I had booked my flight before this change and wasn't aware of the change at the time, and so I didn't select a seat at booking as I didn't realize it was relevant. Better communication about the change would have been helpful for preparing.

Paid for premium extra leg room but the bin space for rows 1-3 had to go in rows 4-6 and 4-6 had to go to 7-9 because flight attendants have snacks and their luggage upfront. So we pay extra to have to fight thru traffic to get our bags. Only 2nd day of new seating so hope they fix this.

Departure was delayed more than 1/2 hour while we waited for luggage (only) transfer from another flight/plane. Once approved for takeoff, the flight was excellent.

Flight was on time. Wi-fi was a little spotty/slow. Boarding and exit were efficient.

Near 4 hour flight with only 1 service. Had to use call button to request water. Internet and power not working until into flight. Internet would stop working during flight.

My flight was delayed 50 minutes and we were rushed to board to then sit for 15 minutes until the pilot arrived. Unacceptable since we could have waited to board. Also the delayed flight was updated AFTER we boarded to more than the 10 minutes as originally stated.

If we are going to have to pay for luggage, make it easier to do. Put something on the app during check-in so I don't need to do it at the kiosk. I've done it twice recently and I ended up having to pay at the desk because something went wrong at the kiosk in Tampa.

Delayed flight. Nicest crew member was a SW pilot flying seated next to me who kindly move to seat the final passenger. Flight extra delayed. My cup of refreshment of ginger ale was so packed with ice it was literally 2 sips.

Everything was on time. I was disappointed by the front section female, African American flight attendant. I did not see her name tag or would have identified by name not race. As passengers moved to the bathroom early in flight, she would say with a disdainful tone “I have to say the seat belt light is on” then go back to her book. Better trained flight attendants say something like be careful the seat belt light is on.

Everything was good except wifi and a leaking drink chiller. The floor was all wet and my bag was soaked. Did not notice until debarking. Have not heard back from Delta. Even though this was leg one of an international flight in first class, they denied access to their Sky Club - very disappointing!

An awesome flight crew. FC seat cushion just doesn’t cut it for a 3+ hour flight.

Delta continues to set the benchmark for traveler-friendly service with minimal disruption and clear communication within the mainland US (coast to coast). I am consistently pleased to be a Delta customer, and this experience once again met my expectations. There was a brief delay departing from MIA due to a technical issue that required the aircraft to return to the gate. However, the situation was handled professionally and transparently. Fortunately, my planned layover allowed ample buffer time, so the adjustment caused no stress. Overall, another smooth and reassuring experience.

Totally worth the miles to upgrade to Delta Comfort. Plenty of legroom.

This was my first time flying Delta ever and I had a great experience!

The flight was great as well as the airline staff

Prior to takeoff, the pilot told us there was a possibility of not being able to land and going to Portland. Well that happened, we took off and then did 8 loops around Spokane before the pilot told us we ran out of fuel and had to go to Portland. So for a 35 minute flight we have now been on the plane for 3 hours (boarded at 6:50 am and landed in Portland at 10:30). Then, we just sat in Portland's airport with no updates of when we can start heading back. All of a sudden, our pilots and crew just left, leaving us stranded in a different city and state. We continued to sit in Portland until we finally got a new crew assigned and boarded the plane (This was from 10:30-2). We then sat on the plane for an additional hour before take off because they had to count us multiple times. We finally landed in Spokane at 3:55 PM. So a flight that should have taken at max an hour took us 10 hours and we missed the majority of the recruiting event we went for.

Comfort seating was on the tight side. Maybe it was a smaller plane(?)

Excellent flight and got us around tough weather. Only issue was seat TV did not work and crew tried to reboot.

Connection through Atlanta was difficult. Mechanical issue on plane caused a two hour delay. New gate was a mile away.

Plane outlets in my row not working to charge phone. Staff response was, well it should be. Plug into seed for volume not working well. Had to find the sweet spot for plug in or it would shut off and on.

Everything was absolutely wonderful from check in to baggage claim. Staff was very professional and sweet. Will definitely recommend United to family and friends.

Very turbulent trip made it pretty bearable, plus the lack of refreshments served and the lack of any air conditioning before takeoff which took an hour or more.

It was nice to have gotten up upgraded to first class with a meal on a three hour flight

They charged a fee for 1st bag checked. Others in same party were free.

Flight team stood out for perzonal attention, kindness at bright cheery attitudes at 8am. Very helpful.

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.

It is clear that someone knew, and competent, is in charge of food at United Airlines at least for the international flights. I was flying in coach, but the choices of the dinner were excellent. Tasty, and appropriate size. I had the beef, which was a little bit like a shepherds pie, and it was good. Nothing comparable has been served on a United flight in years. It will not be confused with three star food, but it is very good for airline food. Even better was the breakfast choice between a cinnamon roll and a breakfast sandwich. I chose the breakfast sandwich which was absolutely delicious and which I would happily order again at my local Starbucks or Panera. It is clear that someone knew indifferent is in charge of the food and it’s about time.

Flight attendant in first class gave poor service (like he didn't want to be there) and food was awful. We sat waiting for gate upon arrival over 45 mins.

Boarding is always an ordeal. Less dogs on flights. I am highly allergic to dogs and cats. Why are there so many animals these days?

I am an AA flyer for a very long time... AA has yet to disappoint.

Everything was good. Flight was very full so crew was busy. After we boarded and plane pulled away from the gate, we were delayed about 40 minutes- sitting on the runway - due to weather en route or at the destination. While weather is not the fault of the airline- it’s terrible to sit on a plane and not moving.

The smell from the bathroom kept wafting through the cabin. It made people sick.

Beverage service was not good. Also just one service in 5 hr 30 min flight. No ask fir water ir anything beside one time beverage service.

Waited for oxygen tanks for 30 minutes after boarding was complete.

Awful. Original flight was delayed 5 hours. Had to to take a connecting flight instead of direct. Had a 4 hour layover. I missed all of my morning meetings getting in 5 hours later than I was supposed to and had to change to take a later flight the next day to get them back in which cia time another $150.

On time on a day with lots of weather cancellations on other flights. Thank you for getting me home during a winter storm!

Don't change gate multiple times make people run across the airport. Announce delays in a timely manner. Have maintenance crew ready. Don't delay and keep passengers on the plane for 3 hrs. on tarmac.

The attendants were kind and helpful. A sugar-free drink would have been very welcome.

Booked through Kayak for $236. They canceled the flight unknown to me; retaining $100 for canceling it. Found out when I went to check in. Rebooked the same flight for $400. Incredibly disappointed. The Sun Country part was as to be expected. Crowded, no food, no arm room but got me where I wanted to go.

3 seperate extremely rude unhelpful staff. Delayed flight. Lost my bag

Sat between 2 big men. I was uncomfortable. Flight was delayed twice. About 2 hours altogether.

It was a good experience. I do wish the seats were roomier. Also, I did not like being charged for my carry on bag

Exceptional take off and landing in snow and wind…thank you to the well skilled pilots!

I liked entertainment system being downloaded on my iPad. The selections were limited but I appreciated being able to use my own screen. The flight was just fine. My only issue was both terminals being far from the main airport. Especially stoning at LAX near midnight and having to wait for a bus to take us to baggage pickup. Very inconvenient.

Just fine but comfort is always an issue since the seats are so close

The Flight was fine, the staff treated me well, the flight got delayed over 5 1/2 hours for maintenance issues....but it worked out OK,, they were very apologetic about it, and it is better to not fly if there is any issue than endanger peoples lives, so in reality that was a good thing, It did cost me extra for parking because I went beyond the time I had purchased for parking at MSP. But all in all, Good flight

I did not take this flight because the reservation made by Kayak was wrong! Kayak owes me a trip from Minneapolis to Duluth.

When I got to the airport in Seattle, they told me the flight "did not exist". Kayak reserved me a seat on a flight that did not exist. This is inexcusable. I was able to change my reservation to a flight that actually did exist, but the flight was later and then I didn't make it in time for the next leg of my trip from Minneapolis to Duluth. Kayak owes me a trip from Minneapolis to Duluth, and a big apology for messing up my reservation.
