It was efficient and great. DIA took a while to let us leave but other than that it was great.

90 minute delay boarding the plane, 45 minute delay on the terminal, 2 hours late arriving, currently waiting 45 minutes on the tarmac for a gate so we can BEGIN deboarding. Absolute mess. Definitely will be my last flight with Alaska.

Extremely professional crew there are very friendly and first class. Everything worked well on the plane. Food was to be expected. Drinks were very good. Shout out to Charlie in first class who was an excellent flight attendant.

The plug in for my charger didn’t work and on my return flight back home the passenger in the window seat got up seven times

The boarding pass had no gate published and there are many fewer large boards with arrivals and departures I almost missed my flight trying to find the gate

Everyone was so kind, flight was wonderful, check in and baggage were easy. Thank you guys so much for a great trip

For such a long flight, Tampa to Seattle, was shocked to learn that no food was served. Also, there were no TV monitors to be able to watch a movie.

The staff at the check-in counter was responsive to the long queue and intervened to redirect the traffic: foreigners can't complete check-in without human agents; that is the real line which moves quickly enough. On-boarding and off-boarding were smooth and civilized. Overall the operations were efficient and the experience was pleasant.

Ok, but nothing special. Long flight with no blanket/pillow set.

Flight was delayed by 3 hrs. Forcing missed connection and overnight stay. Terrible.

Much better than I expected. I had an economy ticket so I was really happy the flight was so comfy and the service so generous. Passengers were all polite too.

It was a pleasant surprise to have complimentary Wi-Fi on the flight

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

The baggage belt was not updated on the Delta App and was displayed on the wrong belt board. Was not expecting this to happen.

The plan was delayed and left DC 90 minutes late. However, it showed a 20 minute delay on the delta app, then a 12 min delay. It turned out to be an hour delay. I found out where the plane was with flightaware. Stop keeping customers in the dark about what is going on.

Pilots lied about waiting on “paperwork”. Sat in the plane for over an hour, waiting on some papers to be printed according to the pilot and then all of a sudden he says good news maintenance is finally on their way. Maybe they can fix it before we get our paperwork. Ended up missing my connection in LaGuardia and as a result, had a fly home to Lexington instead of the Louisville airport. Then paid $100 to uber to Louisville since it was midnight by the time I got in. I wish they would just be transparent with passengers sometimes and not try to beat around the bush on why things are delayed.

One of the flight attendants was a little cranky. I appreciated the free wifi and plug to charge my laptop

The flight was smooth, the crew was great but the plane was quite old

The flight was delayed 90 minutes The Gate was wrong The Restroom on Aircraft was not clean There was a half used water bottle in my seat

It was fine. 55 minute flight. No snacks or beverage service offered. Boarding went smoothly and my walker was waiting for me on the jet way.

Flight delayed two hours , missed connection flight then connection cancelled- horrible experience with hotel

Omg the disaster at the security was on another level! “Go to this end, sorry closed now, go to that end”. Ridiculous! This took over an hour! As far as the airline was concerned although I booked nearly a year ago I couldn’t get my bag tag - stand in another 15 minute line or my seat on Hawaiian Airlines- 5 more minutes! Then my TSA status was denied. Like what the heck! Makes a person not want to travel with this amount of incompetence

The Honolulu Hub needs 2 to 3 times the amount of things to do as well as shuttles that transport to/from gates and terminals. Arriving from OCONUS locations; transferring to CONUS locations its a miserable experience. Fetching and re-checking bags, then returning to a gate across the airport take longer than any other large airport. If youre confused by what I mean, the process goes like this: Disembark plane Walk a mile to the main terminal Walk half a mile to baggage claim Wait 40 minutes for baggage Walk a mile to re-check-in baggage Wait 20 minutes for checking in those bags Fo back through the wrong TSA line because the signage is poor Almost miss the connecting flight because your gate is across the airport.

The checking was disaster, the crew wasn't behave well. It took us two hours to check in, after that thr line at the TSA was long, we barely make the flight. Bad airline

Fabulous if you have a portable wheelchair. They can store it in the galley and you can just walk out with it. Really nice and the flat seats are just incredible, very nice. iPads for movies, also pretty nice,

The crew were exceptionally nice and accommodating. My wife was tired after the flight from Haneda, Tokyo. They let her sleep and served her dinner later after she woke up, before we landed in PDX.

No charging outlets worked. Other than collecting trash attendants didn’t come around. No one could hear flight attendants announcements during the flight. Seat pads were horrible. Sitting on a board for 5 hours. What happened to Hawaiian airlines comfort, hospitality, and extras? Our pilots did an excellent job trying to minimize turbulence and incredible job in landing in windy conditions.

I like that if they asked you to checked in a bag at the gate they give you priority to board

Horrible food and crew. Crew were laughing and talking loud while people were trying to sleep

Yall need to integrate your system with Alaska more efficiently. They booted me off the first flight because of a discrepancy on your end.

On time departure and early arrival. Flight attendant very nice.

American delayed the flight for a crew rest period. The delay occurred late in the evening - the earliest i can find is 10:20 pm. With a 6 am flight anyone on the flight would have already have been asleep (unless you are insane, a vampire or on drugs) and at least for me i was already on the way to the airport at 445 am the next morning when i discovered they delayed the flight until 9 am. Given the incoming flight was in the air at 6 pm the evening before this should have been figured out a lot more timely that was there only crew to use. Just frustrating given there is no consideration for customer experience anymore in flying.

Early departure meant on time arrival. Only real problem was free internet had issues, although chatting with the internet help desk (you can do this via aainflight.com) got the issue resolved.

The "on the ground" A/C was not working. It was so hot while waiting to get in the air, a passenger from the rear of the plan declared "I just can't!" and waited in the gangway until time to close the doors. It was miserable. But the crew were champs and had an amazing attitude. I know they were as miserable as we were but didn't let that affect their performance.

The captain announced to the cabin there would be a delay because they observed a "cut" on a tire during precheck that needed to be cleared by maintenance. We were delayed during this inspection and allowed to proceed after maintenance "measured the cut and decided it was acceptable". My complaint is not about the delay or due diligence. I wish the captain had been more generic when making his announcement. I was a nervous wreck all the way to Charlotte worried that we would have a blowout when landing!

American Airlines is a miserable experience. It is predictably miserable, in the sense that every time I fly American, I brace myself for the certainty that it will be unpleasant and uncomfortable. But it is unpredictable in the sense that I never know if the flight will be on time or delayed nine hours (both happened to me this week). I never know if I will be able to sit in the seat that I selected when I purchased the ticket or if I will be told by Customer Service (!!!) that I must relocate from first class to a seat in the back of the aircraft with no explanation (both happened to me this week). Will the food be frozen and half defrosted, or scalding hot? Will the drinks be warm? Will the flight attendants be surly and mean? Will the toilets be cramped and foul? Will the seats be narrow and uncomfortable? Will there be a real electric outlet at the seat, or just an unreliable USB-2 port? Will there be enough seats in the boarding lounge or just a few? Will the boarding process be smooth and efficient, or will the gate agents mess it up and delay it needlessly for 30 or 40 minutes? Will the catering and cleaning crew be prompt or will they take an extra 30 minutes? Will the brakes on the aircraft work properly, or will the pilot delay takeoff for four hours while the ground crew attends to what can only be described as routine maintenance that should have been done the night before? I've eexperienced every one of these unpleasant things this year, 2026. The only thing I can reliably count on is that American will find a new way to make the experience of flying as miserable as they possibly can.

The staff and service on American Airlines were truly outstanding. I had requested wheelchair assistance for my mother due to her knee issues, and the team went above and beyond every step of the way—from boarding in Boston to our arrival in Chicago. Their care, professionalism, and attentiveness made the entire experience smooth and stress-free. I’m very grateful for the support they provided.

I'm not sure American is capable of on-time arrivals and departures. When you land at ORD, you almost always get held on the tarmac because your gate is still occupied. I may have missed my connection, but that ended up up being significantly delayed as well. Once again, I finally got home well after midnight.

Same plane as RDU to LGA — internet not working. Pilot issue of some sort at end of prior flight - I was on same plane for my connection. Late/delayed —

Human interaction. Thought there would be more service-even a smile would have been nice.

We had better-than-average leg room and I loved the access to shows and movies. During boarding, we could not hear the agent even though we were close to the boarding door, which was kind of scary when we realized that half of the passengers had already boarded. Also, the entertainment was awesome, but I could not hear the movie as well as I would have liked, because my headphones were crappy. It would have been better if I could connect my own ear buds via Bluetooth or if JetBlue provided headphones.

On time, friendly attendants, quick wheelchair assistance and help checking in bags. Also appreciated change in seats, more forward to make it easier for my 97 year old mother to board and exit the plane. Thank you, JetBlue!

Flight did not have onboard charging and TV screen flickering.

I was seated next to an autistic child who was out of control and had a child behind me kicking my seat for most of the trip. I will never fly JetBlue again. Ever. I don't care how cheap it is. It's terrible.

Boarding process was terrible. No assigned seat until the gate, then a long line to get seat assignment.

This was the first flight I've taken since pre-pandemic. I was pleased with how orderly the boarding and disembarking went. The seats were comfortable. I loved that there was no "first class'. The attendants and passengers I met were all very friendly and welcoming.

Boarding was easy. Provided drinks and snacks. Good aircraft and staff

Not very happy because of the long delaying which causes our luggages were not on the connection flight and nearly missed our connection flight.

JetBlue was good. Kayak offered us a deal if we bundled the rental car. This was a complete scam. Kayak said the total was $222... but when we went to pick up the car the agent at Rent a wreck said that we had to pay "fees and taxes" for a grand total of $750. I would recommend not using kayak or rent a wreck. They are both complicit in this scam. JetBlue worked out well.

It was good. I’m very disappointed that they don’t give commentary ear pods for the movie. I forgot mine at home
