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.

We arrived early and finally made it to our gate almost an hour after.

Was a pain having to leave the plane and reboard but glad the plane was fixed

Plane was was better than th YVR to ORD flight but was a fraction of the distance. Fly your better planes on longer distance flights.

Nothing wrong with the flight itself. But due to 2+ hrs waiting in immigration and the additional security checkup in O’hare, I nearly missed the flight.

They need to improve their boarding process. Group 1 and/or paying first class passengers shouldn't be in the middle of boarding process

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.

I still prefer Delta, but Delta doesn’t fly to State College PA.

Everything was fantastic. Modern plane. All the amenities! Although the paid snacks and meals are pure robbery. Like i understand airlines need to make money, but 11$ USD for an overnight oats with some nuts in it and barely any pieces of apple.... Highway robbery

The flight was bumpy. No Breakfast or coffee was served, not even a bottle of water. The food was okay but odd. Rice with peas instead of couscous with some unknown green thing. United Airlines did not tell me that there was VERY LIMITED HANDICAP SERVICE IN NAPLES. De-plane via 20 aluminum steps. Taken to Van. You must walk into the terminal, find luggage, and then walk out to the rental car pickup spot that is 1 block from the terminal.

Crew did their best but the plane configuration is too tight if you're bigger than an average sardine. Controls for the entertainment system didn't all work. The aircraft hadn't been cleaned in awhile.

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.

My flight attendant was attentive! The elderly person next to me was flatulent and the flight attendant could see that I was in distress and brought me some face masks

My boarding pass wouldn't pull up in the app very easily and had to really dig through my email. That caused a delay in TSA..

I had a TERRIBLE experience with the AA crew. I believe it was disability-related. It’s unlikely I will fly AA again.

Baby cried a lot. Nothing anyone could do about it. Just part of flying.

The flight crew was fantastic! Which the seats had a small TV.

The flight was delayed till next day ! They kept delaying every 30 minutes then after 3 hours they delayed it till next day. We kept waiting in line standing more than an hour to get the hotel and meal vouchers. There was no communication at all. Everything was bad

Smoothe flight. Pilot and crew did a great job. Uncomfortable seat in this jet, felt worn out

seats were way too small. Too short of a flight to offer amenities.

The takeoff was the smoothest I've ever experienced on any airline and this is the first time I've flown on frontier so this was an extremely pleasant surprise!

Delayed each time on a round trip with no significant weather interference. Updates to flight times came after the fact. 30 min behind in boarding and board and phone still show an on time departure. Some mysterious extra 300 miles that came so surprising they had to fuel while we were already on board?

A lady asked to stop the flight after the tunnel pulled away and we began to depart a flight that was already hours late. The attendance respectfully stopped the the plane and had the tunnel return. After the tunnel returned the passenger claimed to have changed her mind . The tunnel was then put in reverse and the passenger remained on the plane .. They should have sent the sick passenger off the plane like initially replaced. They existed a couple off the plane prior to that situation.. So.. all and all.. it was a long and flight.. .

terrible cascading delays and unhelpful customer service. uncomfortable plane. crew was great, however!

I ended up paying $70+ dollars to for a carryon because the website is confusing and misleading. I now realize I did not need to pay that. I request a refund. I will pay extra to other airlines and not fly Frontier again.

With frontier you get what you pay for. The flight was two hours late. It’s a tight fit for the number of people they bring but you get to where you’re going cheap. Sometimes that’s more important than a nifty drink and cool TV..

Charges unexpected. For seat that didnt recline. Please reverse extra seat and carryon charge. Bad business that is a bait and switch.

Although we received an email from Kayak AND the airline, turns out we were not on Frontier’s manifest for the flight. We had to purchase tickets at the gate. Not sure where this transaction fell apart, but it did. We are now disputing the charges for the SLC to PDX flight originally booked through Kayak.

We had an awful experience getting our bags checked in. Frontier’s check in on the app manipulated us into buying the business package because that was the only option available for a checked bag which included two checked bags per person which we did not need. Upon arriving to the airport, we stood in line for what seemed like forever at the baggage check in and there was no one available at the counter. We were first in line and we were afraid we were going to miss our flight due to the baggage attendant being late. After realizing there were a lot of other people waiting at the baggage check in and no one available. I reached out to Frontier and could not get any customer service so I had to call the airport to page the baggage attendant to send someone to the counter to check in our bags before we were able to go through security , I finally spoke to the attendant at the counter and explained to her that we had to pay for two checked bags person a total of six bags when we only had a total of three bags between three people she said to reach out to Frontier and they would issue a refund for the three bags that we paid for and did not need. I reached out to Frontier which I was not able to reach anybody by phone so I had to go through their automated chat feature, which sent me around in circles until I finally reached a representative to assist me. I explained to them what happened and they explained that they were not able to assist me. I continued to push the issue with them as this was very frustrating and they finally put in a customer service ticket where we were issued a flight credit and we were so disappointed because after this experience, we NEVER want to fly Frontier again, and we do not want a credit that we will not use. Frontier charged us almost $500 for us to check three bags which is absolutely absurd! The customer service agents were not able to offer anything else other than a flight credit and I do not feel like my frustrations were truly heard , we will never use Frontier Airlines again ! Truly Theft by Manipulation! They should be ashamed!

I couldn’t check in because the app didn’t work. It took 3 Frontier employees at the counter to get me checked in. Flight left 3 hours after departure time
