My boarding pass birthdate was printed incorrectly causing me to spend an extra hour in a check-in and then again TSA line and to miss a chance to have dinner pre-flight. My window seat was given away and was replaced with a middle seat. I would have liked an opportunity to charge my phone and take advantage of movies but many of the departure gate chargers weren’t operational and I don’t know of an in-flight charging option, The flight left 45 late after trouble with unruly passengers, and I was glad staff removed them.

My boarding pass birthdate was printed incorrectly causing me to spend an extra hour in a check-in and then again TSA line and to miss a chance to have dinner pre-flight. My window seat was given away and was replaced with a middle seat. I would have liked an opportunity to charge my phone and take advantage of movies but many of the departure gate chargers weren’t operational and I don’t know of an in-flight charging option, The flight left 45 late after trouble with unruly passengers, and I was glad staff removed them.

Horrible. I likely will have to spend several thousand dollars to rebook my international flights, due to their delays, plus a hotel in SF. I can’t wait to never fly them again!

Quick easy boarding. Airport was unprepared for early landing and we were waiting in the plane for 20 minutes before getting a gate.

It was so easy to board using my boarding pass on my iPhone, and I liked what I was given on the plane for food and drink, and everyone was very friendly.

The flight attendant in the back of the plane was barely understood as she rushed through instructions to the point of being intelligible. She had a bored demeanor in her delivery.

On time, comfortable seats with plenty of leg room, nice staff. Pretty good!

dont re-route to San Jose. Re-route to closer airport. Provide shuttle bus to go to SFO, not just LYFT vouchers.

Staff seemed genuinely nice, not just going through the motions.

I would have rated the entire experience much better were it not for two things: 1. There was inconsistency between what we were told once on the plane vs. the answer I received to the question about "spreading out" from our assigned seats because the flight was sparsely populated, and the entire row we were in was empty but for us. I asked about one of us moving over one seat to make more room for us; before getting on the plane, I was told we could, which seemed like a sensible answer. Once on the plane, it was announced that we needed to stay in our assigned seats despite all of the empty space in our row, which seemed unneccessarily restrictive. 2. To add to the discomfort, we sat on the tarmac once the plane landed in Burbank for over half an hour waiting for a gate to become available. During that time we had to remain seated and buckled in, which was becoming more difficult as time dragged on, especially for my wife. If all of this was due to regulations, that may mitigate the sense of "needless" restriction somewhat, but it points to a need to make regulations less restrictive where it is not appropriate for the current conditions. The crew was not "nasty" about the restrictions, so I do not resent their actions, but it certainly would have been a much more pleasant flight if we had a few more options when it comes to comfort.

I asked to be moved near the bathroom due to kidney issues. The gate agent was very kind and did that for me.

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.

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

The experience was great and much better than the flight going out. of course I was in first class but the service was excellent

Food options were limited which is absolutely embarrassing for a Flight of this size The staff did not come around as much and I am not accustomed to such poor service from American Airlines Drinks I believe were limited to soda and water

Was as expected. Good leg room on planes - much appreciated.

Smaller, regional aircraft limits amount of overhead luggage space. At least there were jetways at both BNA and PHL. First class food service was minimal with the usual assortment of packaged snacks (nothing creative) and no handiwipes. American tries to turn around aircraft too quickly without enough time to clean the planes. WIFI service did not include TV programming.

6 plus hour delay with no explanation. No wheelchairs to transport us on arrival. Very disappointed.

Food choice is limited, entertainment better than average, seat leg room terrible

While I received notice that AA 478 was delayed, the flight departed PHX and arrived PHL more than two hours late. The first class cabin service was mediocre; there were no pre-departure beverages offered; there were no warm mixed nuts served with cocktails; there was no personal greeting to me as an Executive Platinum member by the first class flight attendant. While the flight operated safely, its arrival at 0219 in the morning in PHL ended a very long day. I do not feel that American provided first class service.

Late arrival due to gate being blocked by stalled truck

delayed delayed delayed. was supposed to have a 2 hour layover and very nearly missed my connection.
