The flight was delayed due to earlier issues at other airports. The crew was excellent & made it a good trip.

Full cans of soda would be nice. A choice between two snacks would be appreciated.

The seats were a bit cramped and worn, but otherwise okay.

Gate agents were informative and friendly… flight attendants were as well. Had a fun time chatting about their legacy AirTran experiences as a former fan of the airline that Southwest acquired.

The fluidity of the entire process of boarding the plane the flight attendants attentiveness. The flight attendants also provided coloring books for my kids who loved it.

Excellent. The lady boarding the flight was awesome. Very efficient, and she got everyone on line.

Since the flight wasn’t full, we had some extra room. Crew was great

It was great! The new boeing has much more space and charging ports!

I kept getting h notifications that the flight was delayed. At the airport it was only 2 mins delay. Very confusing. No WiFi on the plan. Snacks very salty. No alternative

I like the boarding procedure. A bumpy ride, but it couldn't be helped. Please make sure the exit seats are clearly indicated.

It was good delayed again but once on board the flight crew were very good the entertainment and wifi worked on this plane and we were offered snacks and drinks

The second half of terminal C at Hartsfield was 80 something degrees. I was sweating just sitting at the gate.

Seat was too small for someone as tall as I am. I was behind an exit row making my leg room even less. There flights were delayed by multiple hours. Some weather related and others staff related. The plane was hot. Horrible experience.

Flight was delayed and then "they did not have time to load food". No snack or drink at all for 1.5 how flight. Somebody wasn't prepared.

Friendly flight attendant Quick checking for baggage drop Quick TSA lines

It was okay. We were delayed for weather reasons, but the pilots and the flight control staff figured a way around the storm and were able to get us to Los Angeles safely. Not all the staff members were polite, but the entertainment on the flight was good.

So terrible. My flight was 4 hours delayed and we weren't notified til last second within an hour of boarding. WE had to sit on the plane for 4 hours. ridiculous.

Missed the Flight from Atlanta to Roanoke due to initial flight from Houston being 2hr. late. Now waiting 17hrs. till my first available flight.

Internet didn’t work for this leg either. The seat was fine but didn’t have seatback screen, which I knew when I booked it. The biggest letdown is Deltas new policy on beverage/snack service not being served for flights less than 350 miles. I know this is a cost cutting measure, but how much does it really cost to give a drink and a snack for inflated airfare? I really am surprised that with Delta Comfort they don’t provide beverage/snack service given these seats cost extra to purchase. Really need to reconsider this, even if it’s for the Delta Comfort and above.

Lady Pilot was perfect in every way wheels up to wheels down communication, professionalism, excellent on time departure and on time arrival, excellent communication! Fantastic job with Superb attitude!!
