Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

6 hour delay including one after we were boarded. Horrible experience.

Horrible. Grateful to be alive but spent 13 hours at airport only to return back to my familys house and flight changed to next day. They tried to fix a part on plane, had no back up plane and after 10 hours , reattempted the flight and it STILL wasn't fixed. We got a meal voucher and rescheduled flight but there should be some other compensation for the 15 hours spent in airport

It was NOT pleasant. Started from checking our luggage to the last time getting off the plane. The crew was not friendly, the food was horrible and the seats were too close to each other that I got a bruise on my knee.

Nothing unusual. It was fine. I hate having to pay extra for my seat.

Everything was Okay. I was disappointed our luggage didn’t arrive with us and came in a flight 7 hours later. Representative said the will be delivered to the hotel. They have not arrived 24 hours later

We splurged and decided to fly first class. Seats were roomy. But flight crew arrived late to the airport. That delayed our flight. Most of the passengers had to try to make connections flights. I felt bad for them. We checked 4 bags. We got three from the baggage claim carousel. 4th one was lost. Delta online help wasn’t good. Baggage claim staff were sympathetic and nice but we waited around for almost 2 hours and it had t been found. They did find it several hours later and we had to drive back to airport to retrieve it. I won’t be splurging on 1st. Lass again anytime soon. I think we got worse service. I am also not a huge fan of delta but we have family in ATL so we don’t have a ton of choice. What should have been an easy flight turned into a stressful event due to flight crew tardiness and baggage mishandling.

Food TERRIBLE! In First Class- so bad - why was it so much better 20-30 years ago? Comfort-awful-would rather have the old, plush First Class seats than the new hard - too short seats in the new pods -would advise avoiding Delta for any International Flights.

7 hour delay for mechanical reasons Handled badly by crew and delta personnel

In thirty years of traveling, mostly with Delta, this was the worst day ever.

The Economy Plus rows weren’t as roomy as expected, and the meal service left a lot to be desired for.

Flight delayed. They made no attempt to get our luggage to our connecting flight so I am without necessities after they begged me to check in my bag. Still dont have it.

The flight was very good. Only complaint was that the usb charging connection did not work for either me or the seat next to me so we both had to use our own portable battery to charge our phones. I also liked the fact that I could purchase Wi-Fi for an hour instead of for the entire flight.

Your seats in the last 5 rows are terrible. My knees were jammed into the seat in front of me and the lady sitting there decided to recline it. Jammed my knees bad. I don’t know if I’ll fly United again.

The flight from Cleveland to Newark was great. The connecting flight wasn’t so good.

This was a short flight with no food. The attendants were great but the comfort was poor: just to cramped. The flight from Denver to Frankfort was excellent! Seating was roomier, food was good, service was good. This was a great experience.

Air conditioning in the plane wasn’t working at boarding, this resulted in a delayed departure whilst they addressed the situation. The cabin was uncomfortably hot.

Delayed over an hour due to paperwork not being filed correctly. Forced to change planes.

I still prefer Delta, but Delta doesn’t fly to State College PA.

The seats on the aircraft are like sitting in a rock. During the boarding process they recognize Active Duty Military, why don’t they recognize Retired Military. I’ve always preferred Delta, this flight confirmed why I still prefer Delta.
