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.

Our travels originated in Spokane to Portland, we left about 1/2 hour late, we had only 45 mins to catch the flight home. In mid flight the flight attend approached us saying that we are going to land after our plane home is going to start boarding. And not only my wife and I are on that plane, but 3 others. We ended up landing about 40 mins the plane started to board, they let us off the plane first, but when we got off the plane and started to go to the next gate, there was no one to guide us or aid us in how to get to the next gate! With that being said, the next gate was VERY, VERY far apart! We practically had to run to the next gate, which was at the end of the terminal. It was not like we took a different Airlines for both legs, but it was the same Airlines.

Excellent gate to gate delivery by wheelchair staff. Really appreciate it!

The flight was delayed an hour and it was not disclosed to the passengers until it was time to board. There was no in-flight WiFI available and such poor communication overall. Unfortunate that I was going to miss my connecting flight with poor communication on alternatives.

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.
