Worst customer service I booked my flight from delta.com but they put me on a flight operated by KLM and I was being put on the standby list by KLM. They treated us like trash after paying a lot to book a ticket with delta. Shame on delta airlines.

Worst airline ever! Worst airline ever!! we bought a seat for our son and the seat was given to some one else we had to hold him! AVOID THIS AIRLINE THEY ONLY WANT YOUR MONEY!

Atrocious service and policies Atrocious service and policies. Was charged $200 just to reissue my boarding pass when there was an error in the order of my name (Middle Name had to be shifted to the Last Name field to match the machine readable area on my passport). Absolutely ridiculous especially since Spirit and Allegiant (supposedly budget airlines) were more than happy to do it for free. The name change service was outsourced to another company called “Flight Trip Charge” as well which made the whole thing seem incredibly sketchy. Honestly thought as one of the major carriers in the US, I would be getting better service. Will definitely avoid Delta if I can in the future.

Awful Awful. I'd paid extra for comfort+ so I could book seats and sit together, and Delta changed them all so we were no longer sitting together for some of the flights. Only got the seats I selected on one out of four of the flights. Staff were very rude when I was contacting them trying to sort this. They then didn't leave enough time for a connection and we missed our next flight. We were bumped down to economy and weren't even provided with biscuits for the next 8 hours we were in their 'care' trying to get to our destination, which we finally arrived at the day after intended.

Nul point Nul point. The rating here on Trust Pilot does not surprise me. Should have checked before we booked! Missed a connection. Delta's fault. Girl at lounge was kind (we had to go there to ask what to do - no other guidance) but otherwise complete lack of empathy from Delta staff at Boston. We are very frequent fliers and know what good looks like. Never again. KLM (who we booked with), what were you thinking code sharing????
