On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

The pilots were good. Disappointing when planes don't have electrical ports

I liked the piloting of the aircraft. Very disappointed about lack of electrical ports. Also, although a short flight. there was enough time to hand out snacks to comfort + seats as was done for first class.

I had a wonderful experience flying with delta. The gentleman taking care of us on our flight was so nice, accommodating, and attentive. He always was smiling and giving pins to the kids which made me smile. The flight was quick too and without turbulence. Thank you for the great flying experience.

Delta is one of the best airlines I have flown

Made the Atlanta to Pittsburgh trip many times, with Delta no issues

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

All flights were on time and boarding was issue free

Terrible! The plane was old and you are required to connect your own device to their Wi-Fi rather than have entertainment options in the back of the seat in front of you. The Wi-Fi went out during the flight and there was only one plug for the devices every two seats. Three out of five surrounding my family did not work. The seats and spaces under them were so small I could not fit my backpack, which I’ve always brought on flights and fit before no problem. The crew were unpleasant and patronizing.

Great! The plane was decently sized and comfortable. The staff was nice and there was great in flight entertainment

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

Our original business class flight was cancelled so we not only downgraded but we were also spread out across the plane not sitting together in separate middle seats. My poor kids were scared and couldn’t see me on the flight and the crew wasn’t sensitive to the situation and what the airlines did to us. Very dissatisfied with United airlines.

Crew were fine, drinks and snacks were as well but we were delayed for around 2 hrs which made our entry into Mexico delayed as well with the influx of arrivals at the same time. Sort of wasted our first day of vacation. We left Pittsburgh at 630am and did not arrive in Mexico until late dinner time.

All four American Airlines flights I took in last seven days were delayed. Caused me loads of problems, missed meetings, loss of time and money.

American cancelled our flight home. Zero option for hotel, alternative transportation and took 3 hours to find our bags so we could take a 3 hour UBER ride home on our dime. Never flying AA again.

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

Flight was cancelled had to move to another gate late again no internet paid for the month and never can use it waste of money

Not being able to purchase my check in baggage online was a negative.

LATE LATE LATE!!! Plagued by late AA flights on this trip. Such a drag. This one was by far the worst.

WiFi connected but only let you go to the AA website, not even text messaging worked.

Too bad that first class seats do not recline significantly causing discomfort

Flight delayed over an over all day until it cancelled at 1:30am. Would not repeatedly delay that late. Offer hotel rooms and rebook early. Very difficult for families with small children

this is starting to seem like an american airlines standard. delayed flights and fake apologies… getting tired of it
