The staff and the boarding procedure were all amazing . The one flight was not equipped with WIFI which now adays seems odd. All in all the experience was good

Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

Really low quality food especially for an international flight. The crew also was surprisingly unpleasant except couple of ladies. I know we were not in first class but that’s no reason to treat customers as less.

Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.

Crew was good. The reservation got mixed up and they didn't have my TSA number. I am also a Silver Medallion and wasn't able to use Sky Priority.

Delta made it easy, comfortable and timely. The crew was fantastic.

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

Delayed due to thunderstorms and no in-flight service due to rough weather — both of which are out of Delta’s control. Flight was good overall.

Flight was delayed not sure why no explanation given and no apologies either. Otherwise the flight was fine

Did not get the seat I selected and paid for.

Crew should be nicer and emphatic with customers. Same cookies as the past 20 years. Seat are ok and the plane was clean though it was delayed.

Plane was delayed for 6 hours, at first by weather, which is understandable, but was further delayed with NO given reason for 2 1/2 hours more. We had no clue when we were going to depart actually until they opened the ramp. VERY POOR to ZERO COMMUNICATION!!!

Flight was delayed and after being in the airport for like seven hours, it was canceled.

Flight delays numerous times. Everytime we would get close to boarding it would be delayed again. Strung along the entire time.

Overall very good, only complaint I have is the crew from CLT to SAT could have collected trash sooner.

Above and beyond effort from this crew in a tough situation. So helpful and understanding. Thank you!

We started with trouble checking in 24 hours early. Then my husband did not get his TSA precheck. Finally flight delayed due to no crew. I know things happen

Delayed because of weather in Nashville. I think God or some higher power generally has cursed me when it comes to flying out of Charlotte on American. I'm delayed pretty much everytime. We need Team Cobra Kai types to come in and "sweep the leg(s)" of the Charlotte ops people on principle. Don't let the sweet southern rocking chairs fool you, Charlotte is a sinkhole
