Great flight. On-time, comfortable, clean aircraft, and offered snacks pre-flight to plan for a potentially turbulent route. I wish there was Wi-Fi an all Delta Aircrafts but for a short flight this is not much of a problem.

Great flight. On-time, comfortable, clean aircraft, and offered snacks pre-flight to plan for a potentially turbulent route. I wish there was Wi-Fi an all Delta Aircrafts but for a short flight this is not much of a problem.

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

If I pay extra for "comfort+" I expect leg room where I can stretch my legs. I was seated with an attendant's seat blocking my feet. Knee space was fine but my feet had less room than the non-"comfort+" seats. Also, don't go cheap on food when you have flights of 3+ hours. It's insulting.

Everything was good except when we're on a 6 hour flight at dinner time and all they offer as part of the fare are little bags of junk food, it's disappointing. Bring back food service without an added price.

I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

Good and consistent Printer in lounge did not work for me :(

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

Delayed in taking off because no flight crew. The in seat entertainment was working properly.

They didn't have any gluten-free snacks, oddly, which I require...or any flavored soda water or decaf tea options, which seems to be standard.

The flight was great, and I have never ridden in first class previously so I don't have any practical knowledge of the norm. The flight out to DFW was delayed and I sat in economy which was as expected, not nearly as spoiled as I was in first class which had more general room but that is par for the course. I have no complaints and will wait until I fly American again before I can make a valid improvement. I will fly American again in the future.

The plane was very warm and the crew turned on the lights for the entire snack service.

No food, no entertainment. But the flight was really short so maybe they had to skip drinks. I was able to board early ONLY because I am old and decrepit and they let me pre-board. I RESENT your dumping us into category 9 if we do not pay up. And when I paid for a seat I was STILL given 9. The pre-boarding helps. THIS flight was exceptionally smooth, please congratulate the pilots.

On time (actually a little early). Was a good and short flight!

Great - quick boarding and landed early with an available gate.

Boston ticket agent Cheryl Porter is WONDERFUL. Our Iberia flight to Barcelona was cancelled the morning we were scheduled to leave and Cheryl was our super hero - she found us seats on a flight to London and on to Barcelona. Truly a “can-do” attitude which we appreciated so much after the Iberia ticket agents told us there was “absolutely nothing they could do”. (As did the customer service agents at Iberia’s call center) Ms Porter is truly a wonderful person who genuinely cares about travelers!

On time, smooth, luggage was out fast at the end of the flight. About perfect.

Flight departed on time and arrived a bit early. Can’t go wrong with that! And makes a travel experience go so well

WiFi wasn’t working on the flight, several delays and gate changes, ended up taking off 3 hrs later
