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.

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.

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.

The seat side plug ins didn’t work in my row, and I ran out of things to do since my iPad and iPhone ran out of juice. The flight attendant offered me a free drink but I don’t drink. I suggested a free snack box instead and she just shrugged and walked off. Why do us non-drinkers get the short end of the stick?

Flight left two hours late with no real explanation and they inexplicably had the heat running on the flight as well

I like Alaska Air fine. Great crew. Late departure still arrived on time.

Plane delayed, emergency light on so we couldn’t board- further delayed, had to sit on run way for an hour for other plane priority

I missed my flight and was not able to rebook. I switched to jet blue for a same day flight. Both legs were cancelled. Unacceptable.

It was just fine. Short flight so nothing special to comment on.

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

I always fly with Delta. My friends tell me their horror stories of flying with other airlines. I just smile and say, “You should fly Delta”

I'm a larger, athletic guy (6'2", 260lbs powerlifter) and I found the seats incredibly uncomfortable with minimal leg room, especially in a window seat. Now, I full understand that being smaller may change my view but even if I was 80lbs less, my legs would be the same size and I was sandwiched between my seat and the seat in front of me.

Horrible. This was not first class. This was a connecting flight whi h was late. My original flight never came. I hated the fact that delta gave me a connecting flight from New York to Orlando Florida. No meals and the television screens were not working. There wasn't even any power to charge your phones. This is NOT FIRST CLASS DELTA!!! Do better next time!

This flight was ridiculous. I had to have a connecting flight from New York to orlando Florida??? The flight left late and because it was a short flight there was no first class amenities. I had one alcohol drink. The flight crew was fine, but it sure did not feel like first class. Delta to me dropped the ball by giving me a connecting flight. By the time we got to Raleigh we would have missed the next flight. Lucky for me the flight never came so now I was stuck waiting for a later flight that came in late also.

Our flight was delayed in Atlanta. The staff could have gave us an explanation for the delay and how long it would be.

I liked the ease of checking in, luggage check in, wheel chair assistance, boarding and flight.

On my way home I had a layover. The flight from ATL to CLT was amended 5x while I was waiting. I could have driven home sooner. Overall from Dallas, Tx to Charlotte, NC I started my trip at 4:30pm, I didn’t get home until past midnight. I know things happen, but 5x to make me run back and forth in an airport from different terminals is excessive. I also upgraded to comfort + , I didn’t feel it was worth it. There was no benefit

They did a fine job. Can't wait to use Delta in the future.

This flight was delayed approximately 4 hours due to bad weather in HNL.

Flight delayed then cancelled then gate changed two times then baggage lost.

The plane is extremely loud and there’s no place to charge devices.

Not great to be very honest. Our flight was delayed after we sat at the airport until 15 minutes after we were supposed to leave . We were then notified the plane was being worked on “and the parts were out in the ground and still not finished .” Even though the work started the evening before and they knew it wasn’t fixed. . Then we were told it would be a 1:15 pm boarding time so we waited then at 1:45pm we were told it would be an 11:15pm boarding . It was changed to and 3:55am boarding the next morning . We lost out on a day in Hawaii and a night of our VRBO rental.

Safety record impeccable and important since flying many hours and thousands of miles over ocean.

Love the food service and attentiveness of the crew. Could have wi-if on flight

Seats on second leg from Hawaii to Tokyo would not recline. 9 hrs is long in total upright position.

Apparently the computer systems were down, so I wasn’t able to check in 24 hours in advance, despite multiple times on the app, the website, and by calling. Then I arrived at the airport and wasn’t assigned a seat right away. I had to wait until I was at the gate and waited about another hour for an agent. She was nice to give me a “free upgrade.“.

The crew worked to help us find standby seats and we were able to arrive at our destination early which was great. Only drawback is airport at Kona which is in need of update - waiting at gate passengers exposed to jet fumes, there’s only one restaurant with minimal choices, etc

Increased effort to keep family members (purchasing multiple tickets in the same transaction) sitting together. Additionally, when faced with choosing seats at the automated check-in kiosk, only exit row seats charging an additional $9 were available, but if you decline to choose seats, it picks seats that are NOT exit row. How does that work, Hawaiian?

So so. Terrible aircraft choice for that leg of the flight.

Due to one crew member not showing up to work, our flight was significantly delayed causing us to miss our connecting flight in Houston to Mississippi causing us to be delayed by more than 6 hours and missing our event all together. Very disappointing. All because ONE crew member called in sick. United did grant us a $15 meal voucher, which was a small but appreciated concession that I wasn’t able to use because I ordered my lunch and paid for it before applying the concession, and the staff said it was too late to use it. Ugh! We also had a TWO delay coming back from Mississippi, but that was on American Airlines and it was due to weather, so not their fault. Anyway, not at all impressed with United’s handling of our flight and the HUGE disappointment of missing our important family event for our 90 year old mother. All that money and all that stress and emotions for nothing. Having to wait the hour to bring an employee from LAX seemed like something that should not have happened. Why don’t you have a local back-up? Santa Ana is not a little airport in a rural area.

Flight delayed from Cape Town to Washington then got diverted to miami and in miami we had to fend for ourselves , im still trying to get to Shreveport now

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

I just wrote a text which was supposed to be for the flight from Denver to spokane not Frankfurt to Denver.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

flight delays, staff only communicating when pushed, food service lasting a grand total of 7 minutes, stuck in seat from 45mins into flight until landing

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

they made me check my carryon. There was space in the overhead bins.

This flight is frequently delayed. The connections seemingly are more frequently delayed. I’ve missed connections as a result twice on the same route to charlotte then Charleston. Final destination arrival has been the next day, twice in a row. No pilots, no crew. Too many excuses. Unfortunately, my days with American are over.

Entertainment was okay not because anything was wrong but it is a short flight so having no wifi is annoying but understandable. Crew was outstanding as usual

Those seats were way too narrow. I had the middle seat, one person was a very skinny person and we still couldn’t avoid touching each other anytime one of us moved. The other person was larger and we were basically sitting in each others lap the entire flight. There was zero entertainment. The flight was long enough to justify tvs, but no. Gotta sit there in your infant seat and twiddle your thumbs.

The Flight attendant had an attitude and didn't allow anyone any time to prepare for landing despite being absent throughout the entire trip

Flight boarded without pilots. Sat on plane for 3 hrs. after over an hour late boarding. Plane never took off. Had to deplane near midnight. Line for rebooking was 3 hours + long. I had to leave.

The flight was great but board was a nightmare. The gate was changed 4 times during the layover period

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

Cold air blew constantly on my legs almost making me numb.

Missed the flight because of them and up geting a rental car

Delayd flight out of atl as always miss my conection in dfw no flight untill next day
