Probably not the fault of Delta but there was delay after delay after delay and I ended up getting home 4 hours later then I should have at 1:30 in the morning

Easiest airport experience ever in my life at MSP with Delta check-in and flight attendant gave us a bottle of champagne in celebration of our 10-year wedding anniversary, so overall amazing!

Staff was exceptional! Everyone was kind, professional and friendly making the trip very pleasant. Thank you!

Great. Seamless. Check in agent at kiosk international was amazing and extremely helpful.

Very late arrival at PWM. Late jet getting to ATL. Equipment problem with aircraft - could not get enough water onto plane., Another delay getting FAA approval for flight with bottled H2O. Not the crew’s problem.

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Pretty standard flight. Delta has a good selection of movies.

The flight was so late that I had to change connecting flights, turning a five-hour trip into a fourteen-hour nightmare.

Delta planes have the WORST seat comfort of any plane in history. It's the opposite of ergonomic, in every sense. They also recline minimally, are covered in a vinyl and have no feet rests. Then the disembarking process is chaotic and time consuming (because of the way they load the plane and deal with luggage). Overall, somewhat frustrating but we arrived safely :)

Despite being delayed, we would still give a high score for this flight experience. For the first time in quite some time we had excellent customer service throughout our entire round trip. The flight attendants were the most polite we have experienced in our last ten flights at least (non of which were Delta and include business class). The food offered was a better selection than most—we just didn’t have any of it. Overall, almost as good as flying used to be. Thank you to Delta.

I cancelled this flight 2 days before departure but I followed your texts and emails and IF you were correct this flight turned into a nightmare.

Crew was helpful and cheerful especially when they had no refreshments to work with. The plane was never serviced and had nothing but limited water and coffee onboard. For the price point, a concern of services.

I bought wifi and most of the flight could not even use it my apps would just spin. I couldn't even listen to music. super frustrating.

Seating was horrible. Small seats. Access to flight information and extras very iser unfriendly. Kept losing internet after paying for it. Staff in madison was as unprofessional and unhelpful.

There were several different delays but we ended up being delayed a total of 40 mins or so. It was annoying we had a gate change which made it take longer to leave DFW, and we had to check our carry on. Ugh

The counter/baggage counter was busy and so many people missed flights. We got stuck sitting on the plane over 2 hours at the gate while they were doing an inspection is wrong. Many of us missed our connecting flights because of it.

A much better flight than our previous. The flight attendant took care of us and regularly checked in to see if we needed anything. Brought us drinks prior to the departure and then a couple more times. Totally makes the difference in how you travel when the crew is checking on their passengers. Great job on this leg of our trip.

Our flight was changed from Madison to DC to Madison to Charlotte.

We were told we had no flights before our flight was continually delayed then cancelled.

Boarding was relatively fast and easy and the crew was attentive throughout.
