Fine, but how to board on SW versus othrr airlines, is just lame. Goood staff though and all was solid otherwise.

Fine, but how to board on SW versus othrr airlines, is just lame. Goood staff though and all was solid otherwise.

The last 30 min or so, they put the heat on full. We thought we were being basted.

The plane wasn’t full, so we got the best seats

My experience was find with Southwest. The only issue I have is...at the exact time for me to check in...I don't understand how I always end up in C.

With early bird check in, I might start flying southwest again.

Very helpful, convenient, nice crew members, no extra fees, helped us saving 4 hrs of travel by booking is on an earlier flight

Because of storms in St Louis, plane was diverted to Kansas City. After about 1 hour stay went back to st Louis to finally reach distanation. Made for long day. But southwest took care of us. Can't fight mother nature

We stood on the tarmac for over an hour. Very bad turbulence the whole ride. Very to get to the restroom.

Our first flight was so delayed that we had 10 mins to board the next one. We requested if the flight attendant could allow us off there plane first and they denied our request even though I have seen this done before. Luck was on our side that we didn’t miss our next flight.

It was good. I wish you had gluten free snacks for my husband.

Seats were the least comfortable that I can remember ever having. Seat location just across from lavatory doors was not a good location to say the least. Wife has a back problem and to have a seat that is no adjustable for posture was torture for the three plus hour flight

I flew from San Francisco to Honolulu on Hawaiian Airlines. The flight was operated by Alaska Airlines. Everything was fantastic. On the return flight from Honolulu to San Francisco, boarding was chaotic. They called each boarding group 1 through 6 very quickly, and everyone just ran and got in a very long line. There was no enforcement of boarding groups. Carry-on rules were not followed, and by the time I boarded the plane, there was barely any overhead space. I was boarding group 4. The crew was very professional, and the Hawaiian Airlines terminal in Honolulu was beautiful. I wish the rest of Honolulu Airport looked like the Hawaiian Airlines Terminal.

The take off and landing were smooth as was the flight. The service was great. Bathroom was clean. Thank you

From my interactions with the Oakland airport staff through TSA through the gate agents to the flight crew on Hawaiian they were just so kind professional and helpful.. the only thing I would add would be the they need more help and TSA and on the Hawaiian airlines flight it would be so much nicer for them to play beautiful Hawaiian music on the way over there.. they didn't start playing it until right before we landed..

Would like to see more consideration of older people. I have issues with being on my feet and walking too far. You put me in the last seat on the plane. Way in the back. Other than that everything was vey good.

Portland reservationist required me to check bag… tho always been ok as carryon before this experience. She didn’t ask my name or destination, seat number; only looked at boarding pass. She then sent my bag to wrong destination: Idaho Falls instead of Bzn, Mt. I spent 1 hr in Bzn trying to get this straightened out and locating where my bag might be? The Bozeman customer service was great and figured out the error that occurred in Seattle. They were wonderful, filed a claim and located my bag. They also offered me compensation for my problem which was helpful. Missed my meds last nite and following morning. Hope this will be resolved later today. 🙁

The app is very bugy, did not work well. Other than that it was ok.

Not sure why the counter agent's couldn't have helped us with our flight change and only gave us a number to reservations. I thought their job was customer service, not "call this number"

Nobody’s fault but turbulence all the way meant no service and no access to the bathroom,

late, water or apple juice only, short on overhead every flight announced

I was with one of the last zones to board. It was kind of annoying to finally get called to board and my whole section was already on the plane. Clearly they boarded with previous zones. So by the time I got on board, there were no spaces for my luggage above my head. I had to put my luggage 4+ rows behind me, which meant that I had to wait even longer to get off the plane, since I had to wait for those rows to clear the aisle before I could retrieve my luggage and exit the plane. This also held up the plane cleaners, as they couldn't service my row until I cleared it, so they were all standing there waiting for me, while I'm standing there waiting for the other passengers to clear the aisle. Anyways, I wasn't in a rush this time, so I just waited, but I could see that being a problem in the future. Now, I could have checked my luggage, of course, but coincidentally, a friend of mine on the same flight got their luggage damaged (wheel completely knocked off) and was told by the Baggage Attendant in the airport that Delta doesn't "cover wheel damage" on luggage. This was disappointing to hear. I'm glad I didn't check mine through. If it were my luggage, I'd be highly frustrated to hear that. It makes me not want to check my luggage in the future.

The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?

Typically I give delta excellent reviews. Our flight was delayed 2hrs, I was one of the fortunate ones who were able to get to my connecting flight. Also, annoying that on the connecting flight boarding personnel make me put away a small bag into my carryon. It small enough to put in back pocket seat, why hold me and the line up to just push it into my carryon.

Everything was great. Great service, excellent communication, and early arrival

Delta flight attendants poorly managed the boarding process and overhead storage. My bag was checked last minute and no claim ticket was provided. My bag is now lost. Complete incompetence by all flight crew involved.

Inexpensive, got an exit row aisle aeat with no middle passenger, bought a great breakfast sandwich, flight comfortable & arrived ahead of schedule.

Customer service at the gate in the flight was exceptional. On time. Aircraft and seat was decent. Thanks Delta. 💗

It was terrible, if they ran flights on time it would make a big difference.

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.

How badly can you screw up baggage claim? We were told to go to baggage claim too for our bags from this flight. Another flights bags were there. They finished up. More bags from a different flight arrived. Our bags did not Finally the baggage claim belt stopped working and and are flight was still listed on the arrivals for that baggage claim 2. And then nothing It turns out that they had been delivered not only the United baggage claim but far away on a Delta baggage claim No I never told us. It was only the people looking around who had been on the flight But I’m sure there was plenty of time for the employees to raffle through the bags and steal whatever they wanted

Sucks ! All three flights I was on this trip were delayed.

Long wait before take off without an update for 20 minutes. Flight was good otherwise.

Flight crew was amazing! I don't like that the Polaris seats are side-by-side.

Everything was awful Flight attendant was condescending, rude and not helpful at all. Small outdated plane. No service, uncomfortable seats. Flight attendant was really the worst. He used hand gestures to communicate instead of words and whenever he used words he was condescending.

The entertainment would not work. The comfort of the seats leaves something to be desired, pretty uncomfortable.

Short flying. The seats do not recline at all and very uncomfortable.

Delayed over an hour due to paperwork not being filed correctly. Forced to change planes.

The departure was delayed by 1 hour. The seat was comfortable and selection of entertainment is very good.

I was refused to used the toilet closes to my seat and had to go to the back of the plane .. it was difficult for me I’m a wheelchair customer

A thousand choices for movies and nothing to watch. I avoid 'R' rated shows and others with violence and sexual content, which results in a handful of flicks to view and I have them already.

Two issues. The plane was old and dirty. The armrest looked like an old car that had the vinyl rubbed off. The Seats in these aircraft are about as hard and uncomfortable. I want to tour Italy for a month and I want to buy a one-way ticket to Thailand but I will not sit in the seats these planes have. It is seriously stupid how hard they are.

The gate changed over 6 times in the 4 hours before this flight having us walking all over and back again. The agent told me that the American app and the airport monitors are not reliable and I should Google the flight number for accurate flight information! Shocking tip but the gate still kept changing anyway and then the flight was delayed an hour because of another maintenance issue. Not a great experience.

Promised lounge access, gate agent didn't allow us entry.

I was in a wheelchair and went from international to domestic. I was transferred to several different modes of transport and expected to give a tip at each transfer. I was, although, grateful to get to the gate in time for my flight.

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.

It was okay. I opted to pay for an upgrade to an exit row, but this might’ve been the worst exit row experience I’ve ever had. - The fold out table was janky and didn’t fold out properly. - The seats felt squished together as I was the aisle seat in the group of three, but the guy in the middle felt like he was constantly leaning on me. - Everyone who walked by brushed up against me, or knocked my entertainment screen, to include the food and drink carts. Didn’t get one apology or excuse me. - The community flight tracker screen was right in front of me and was sooooooo bright I could barely catch any sleep on my 13hr flight from Seoul to DFW. Not the best experience at all…

Packed commercial flight was as comfortable as can be expected

I'm not a valued flyer so I'm always in the last group to board...that sucks, always

Domestic airlines have really fallen from what they used to be.
