Enjoyed it very much. Especially liked the free WiFi that Delta offers.

Bus to plane was delayed for no apparent reason and our luggage was still on the belt when they shut it off. Took about 20 minutes to turn it back on to get our luggage.

It was a pleasant surprise to have complimentary Wi-Fi on the flight

Round trip flight to Canada and back to the US was smooth and efficient.

I am writing to express my dissatisfaction with the poor service and unprofessional staff we encountered when traveling with an infant. Our flight was delayed, and the gate staff failed to manage the boarding process appropriately. Due to incorrect, unavailable, or missing 'pink tag' stroller and car seat check-in procedures at the gate, we were forced to board last. Furthermore, the gate staff was rude and dismissive, causing significant distress to our infant. To make matters worse, one of our checked items—an infant sleeper/lounger—was returned to us broken. Given the unsafe handling of essential equipment and unprofessional treatment, I expect a prompt resolution regarding compensation for the damaged items.

My seatback screen didn’t work so that sucked because that’s what I was going to do on the plane.

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

The staff was frielndly. The plane was terrible, it was too small and should be decommissioned. There were no back seat screens at all. The only beverages we had a choice from was coffee, tea or water. The only bathroom in the back was behind the flight attendant's jump seat and wasn't working. And I literally felt like I was sitting on top of the guy next to me. It was terribly hot in the plane and we had to sit on the tarmac in Chicago for 1/2 hour due to congestion in Mpls. Wouldn't they have know that before they even boarded us so that we could have sat in comfort in the terminal?

Terrible. Four hour delay because Delta could not find crew to man the aircraft. Terrible communication. Terrible insight into the delays. One of the worst flight experiences I’ve had.

was sitting in the jet bridge for 10 minutes in -20 degree weather waiting for my bag

New plane was lovely. Crew customer service is always lax but expected. Kraft on time and arrived safely.

It was a short flight so I was expecting too much

Had a one hour delay due to mechanical issue. I didn’t think I’d be able to make my connecting flight, but they waited for me and greeted me when I arrived to help things run smooth.

O’hsre taxi and deboarding took 40 minutes. Needed 20 minutes extra time between connecting flights to avoid running through terminal.

Was great in general, try to respect time and excuses when slight changes have been made, appreciated!

Really hard landing... as in slammed into the runway then hit the brakes really hard ...

Every staff member was professional, friendly and courteous. The pizza twist was ok. It was warm but too much dough.

Wonderful in-seat entertainment with seatback screens and huge selection of quality movies. The ability to bluetooth connect headphones was amazing.

Flight left on time and we arrived 25 minutes early! There was a gate available when we arrived so early on a busy Sunday afternoon! Flight attendants came around twice with the drinks cart.

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

Boarding and crew were great, but seats are terribly uncomfortable. No food or entertainment options.

Everything went very smoothly! Thanks for a great first experience flying with small children!

Crew members great. Everything else a 0! Got on plane at 530am. Got de boarded for mechanical issue. Supposed to leave by 830 am. Zero communication from gate agents. Then supposed to leave by 230pm. Then delayed till 330pm. Still zero communication with gate agents. All they would say is if you have an issue call the 1800 number. You call and sit on hold minimum 45 minutes for zero answer. Finally board at 345pm didn’t take off till after 4pm! Sat in airport for 11 hours with 4 adults and 3 kids. Finally offered a $100 (we are sorry) voucher for next trip. Missed whole day in Florida had to change reservations in Florida! Absolute joke of an airline! And I usually really like sun country.

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
