Crew was great flight was great baggage claim was a failure. It took over 1 hour for bags to arrive. Poor communication poor effort when I spoke to the supervisor about the delay

Much better than the.last. flight on SW on Thanksgiving day

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

The movies using Southwest WiFi kept pausing and I had to restart multiple times.

It went well. Plane wasn't full. Will be great when assigned seating is in place

Everything was great except the food. The pretzels are really crappy.

For the first time in a long time we had a flawless experience with Southwest. Both flights were early and no mechanical errors at all. We were shocked and pleasantly surprised 😮.

It was fine. For some reason the flight was much longer than usual. It may have been explained, but I had noise cancelling earbuds on and missed a couple of announcements. The crew was fine, but there was a flight attendant who kept telling dumb jokes, occasionally one I found distasteful. This was my second time with him, but luckily it was a late flight so he didn't do as many. But I heard all of today's jokes twice, which was two times too many. Good takeout and landing.

One of the crew performed a hilarious skit to accompany the standard instructions. Passengers enjoyed it so much they applauded at the end!

It was really nice! I appreciate the gate attendant allowing families with small children to board early on in the process… that was very helpful! The internet service didn’t work with the app I was trying to use even though I paid the $8… other than that it was great! Oh and I should’ve asked for the whole cranberry cocktail can. That cup was about 2 sips…

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.

There were no movies, have to pay for internet, only pretzel, cookie, & a beverage for a 7 hr. flight..

I did not purchase this flight nor have an account with Kayak. That person used my email to sign up for an account to book the flight. Reached out many times, chatted with a representative, no response from anyone. EXTREMELY POOR SERVICE FROM KAYAK.

My flight was cancelled last minute with zero acceptable options and reimbursement. I called Alaska and was told I had to pay for my own flight home so I bought a ticket for $500, I missed work worth $450. I had no babysitter for my child and her father missed work for another $480. I have diabetes and health conditions that require medication and proper diet which was extremely difficult with only $48 of vouchers and not enough medication for the extra 24 hour to 48 hour delays home. I understand things happen but the support Alaska gave wasn’t responsive enough to compensate or reimburse for the inconvenience. It took several hours to get a hotel for the night as Alaskas link was incorrect, vouchers were used and had no more rooms, people were walking the airport 10x to be told their next flights weren’t accurate home. If someone was disabled I don’t know how they even got support.

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.

If I pay extra for "comfort+" I expect leg room where I can stretch my legs. I was seated with an attendant's seat blocking my feet. Knee space was fine but my feet had less room than the non-"comfort+" seats. Also, don't go cheap on food when you have flights of 3+ hours. It's insulting.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

The food for long haul was poor compared to Singapore airlines economy. Pasta plain with tomato sauce . Singapore airlines give me Hagen dash small ice cream cup it was great. The choices of dinner course Singapore air also much better The crew mostly friendly. The economy seat are as expected.

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

Flight was 3 1/2 hour delayed with no credit or meal vouchers

late departure due to some unspecified issue with ventilating the cabin. They got it running but it was FREEZING for the whole flight. I asked for a blanket but they didn't provide one. They could not turn up the heat. it was quite miserable.

Liked that we left on time for each flight. Snacks not the best, but we're okay.

It was fine. The flight attendant appeared to be in a bad mood but everything was fine.

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

Pleasant service from the crew. Arrived early. Efficient boarding and deplaning. Great job!

Everything was perfect except the pad at the top of the seat back. It pushes my head forward in a very uncomfortable position and it is not removable.

Flight attendant walked away once they landed and we were forced to wait another hour after an already 3hr delay.

No overhead space so all carryons were checked. No internet.

The flight was on time and everything went very smoothly.

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.

I think I paid for an extra legroom seat and to be honest, there was not a lot of space available for my not very long legs. The flight was totally full and the staff did everything possible to meet the needs of all passengers. My only concern was for the size and spacing of my seat.

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 meals were mediocre and the alcohol selection was poor. I enjoyed the selection of movies and other entertainment.

I chatted with the captain before the flight, and similarly during the welcome announcement, he warned of a turbulent flight that may impact the in-flight service. However, once at altitude, he announced that the weather changed and he immediately turned off the seatbelt sign. But it appeared the cabin crew had already decided to take off this flight. They remained seated and then just chatted in the galley. The flight was fully catered, but only first class received service.

they should make XXL people buy two seats. sitting next to a person that was half on my seat and could not even buckle the seat belt, so I had to lean in the isle the whole trip.

The flight left a bit late, but arrived close to time expected…With the flight being close to full the crew did well serving drinks to all in a very timely fashion. The flight was a pleasure…
