TSA lines in Seattle can get very long early in the day. Also, plan to return your rental car early since you have to take a shuttle bus to the terminal and those lines can get long early in the day, too. Currently there is construction in the North Terminal, so be prepared for moving around barriers. The day I flew out, the escalators were not working.

The flight was okay. The pilots did an amazing job and kept us updated on the flight. The flight attendants were okay. They found time to be chatty with each other rather than focus on the guests. One of the attendants was a little less warm when asking about my bag I had on my lap that I was using during latter part of the mid- flight. Mind you, it was not the departure descent. I’m respectful to each and every attendant, it was the tone in her voice reminding me to place my carryon bag on the floor. I hope to have a better experience next time.

The entire travel day was a disaster from beginning to end. Woke up at two in the morning to make it to San Juan airport in time for a 5:30 am flight to Milwaukee which connected in Baltimore. Massive delays lead to me missing original connection out of Baltimore. Sixteen hours of delays/rebooking/layover time later, arrived in Milwaukee to find that only one of two checked bags made it there (despite the fact that Southwest brought another 737 jet to San Juan to fly us out to our original Baltimore connection—-not squeezed into another booked flight). The flight from Baltimore to Milwaukee was barely half full, so there was no logical reason to ship my bags out of Baltimore on a different flight to Chicago to then ship to Milwaukee. Southwest decided that my bags should not have been on the same connecting flight I WAS ON to Milwaukee, and then proceeded to accidentally leave my larger bag with the important items in Chicago. Terrible logic and support all around. Extremely angered and disappointed with SW. What a clownish operation your company has become!

It was as expected and I was grateful for the wheel chair help and ease of use.

One of the best airlines for fast boarding, on time arrivals, and top notch service!

The new seat assignment thing is wierd. If you don’t pay for a seat they always assign you a middle seat regardless of how many people are on the flight. Idk… the new company that bought Southwest is trying to make it more profitable, but I’m just not seeing it. The flight attendants aren’t having as much fun anymore. It just feels like the airline is slowly dying. IMO. We shall see if Southwest is the next Toy’s R Us.

Terrible. Even though there’s assigned seating now, they are still the slowest boarding airline of anyone.

The Air hostess were very rude on my flight from Houston to Austin . Their regular communication itself felt a they are shouting at people.

Communication about the delayed flight was poor. We were told to move gates three times but that was bad information. We went from gate 128 to gate 126 and then to gate 123 and back to gate 126. Communication about the delay was bad. Ended up being 1 1/2 hour late getting home.

Plane was late. Zero service for 2+ hour flight and it was not that bumpy.

It was good from LAX to Phoenix, But the connection in Phoenix to Tulsa was not that great. The staff on both flights were great. The choice of free entertainment was ok nothing to brag about. The 45 min delay because of some electrical issue wasn't great from Phoenix to Tulsa. We sat there with hardly any air, The seat I had was between windows so the side of the plane pushed in on you. My being a bigger man it then made the seating area uncomfortable. The seats on the plane had no power to connect to recharge your phone or anything. I would recommend that they should look into a slot or clamp to hold your phone to enjoy while watching the entertainment choices hands-free. Also make it possible to raise the inner seat by the window be able to raise the arm rest up to make more room for larger people to set more comfortably. I would also say other then that stop price gouging the airfare or nickel and diming everything. Not fair for people having to fly for emergencies and be paying for higher prices due to the season or holidays. Your making your money either way and the cost of flying is still going to be the same regardless if there's 100 people or 200 people.

Loved this first class flight! Awesome food, snacks and drinks. Comfortable seat with foot rest. Good movie. Very friendly crew! Only thing I would suggest is having a screen on seat back in front of me so I didn’t have to watch the movie on my phone.

The crew was very attentive, boarding was orderly. I really liked the way Alaska Airlines gives boarding passes and dropping off my bags. Very smooth.

Once we were in the air, the flight was nice and smooth. The flight was about twenty minutes late to begin with, though, and then we needed to wait to land for another plane to land first.

Flight crew great! No WiFi not great. Someone took my bag not great!

Alaska Airlines staff go out of their way to accommodate my fragile musical instrument, every time. They are unlike any other airline. I've experienced this can-do attitude on several flights with different staff, so this must be the culture of their company. I appreciate Alaska!

We never had an experience on Alaska Airlines. We missed our flight .

Flight was on time departure & arrival. Staff was efficient & attentive. Food was better than normal. Wish they had some sort of entertainment screens loke Delta. I would fly Alaska again though.

It was a bumpy flight but the crew was very attentive and made it a safe and enjoyable experience.

Very easy, stress free airline. Was a wonderful experience. Will use again

The final trip home wasn’t as bad as the trip there. Even with the paid upgrade the comfort level was mediocre at best.

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

No entertainment. Plane was so small had to pink tag a carry on ive used for 20 years easily on board. The fact the flight got in at midnight, had to wait for crew in fort wayne to allow the plane to approach the gate, THEN had to wait for bag on jet bridge made experience irritating at best.

Crew was great. Near on time departure and early arrival. Snacks are always meh. Not a fan of the "pay for everything including miles " proposal unless base flight rate going to be 100 bucks.

Would have been better if there was a nonstop flight from Tampa to Norfolk or Tampa to New Port News.

Overall Good! The weather delayed our takeoff from Atlanta and our arrival in Miami! If Mother Nature can mess up a flight she will do it every time!

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

Snacks and included beverages were appreciated. Boarding went smoothly. Plenty of overhead bin space. Seats get very uncomfortable after a couple of hours. After waiting 10 painful minutes for my walker, a very nice Delta guest agent pushed me in a wheelchair to the gate. It was finally delivered to me after another 15 minutes . Our checked bag was on the carousel long b4 I was able to retrieve it. Fortunately it was still there but somewhere along the way the straps we used to secure it were removed and and were not reattached. Wish I had made note of the agents name.

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.

The cabin temperature was nice and cool. The wifi was not working.

Could not get my connecting flight boarding pass until four hrs before departure! Ver annoying especially since the staff could not explain why!

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.

There was no wifi available at any price -- the plane did not have wifi equipment. Movie choices were blah - hits from the past; nothing recent. The food was blah airplane food. They should have had Mai Tai drinks available as per the Hawaiian Airlines magazine, but they had none onboard.

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.

The crew at Hawaiian Airlines was fantastic. Kind and hard working. The pilots were great with giving us all the updates to make sure we were informed.

When I booked my flight a month ago - I selected a seat. That seat was NOT the one I ended up with when I checked into my flight the day before. This is the second time this has occurred. So, I checked my next flight on Wednesday and Thursday and no seat was assigned. Poor, very poor customer service.

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.

Incredibly delayed. First delay was due to plane coming in being late. Resulted in 30 minute delay. Boarded and then had multiple mechanical issues. Was on plane for an hour until they told people they could get off if they wanted but couldn't come back. Then gate agent rushed in and said they had lost control of who went off and we would all have to deplane and then get back on. They said flight had not been cancelled. Then while sitting waiting to board again they announced it would take two hours to get new plane and to wait at new gate. New plane arrived, reboarded only to find out that pilots had timed out. Waited for new pilots. In that time one of the flight attendants timed out. Never received food or water while waiting. Was confusing mess as to what was happening. Even flight attendants and gate agents were getting frustrated. Almost 6 hours delayed. Called American to received flight credit but can't get anywhere as Kayak reservation and don't have a ticket number. Reached out to Kayak but never heard back.

American flight was diverted and delayed but app didn’t show that information so I wasn’t able to change my connection until the last min.

Wifi was spotty. Tray table was very dirty when I sat down.

Very disappointing. Flight was delayed by 1.5 hours and food options are very underwhelming even for first class seats (same food given to economy seats)

Was not able to do a online check-in because the American Airlines system doesn't store our visa or other passport information, allowing us to have a trouble-free check-in. We were forced to have to check-in at the counter which Changes are upgrade status given that we were not able to check in much earlier.

The plane was very creaky and lots of ringing. Plane was dirty and dingy. I couldn't hear the captain's announcements from the flight deck. Not sure if it was the captain or the audio equipment, but good thing there wasn't an emergency where we needed clear instructions. The overhead compartments were clearly full, but the flight crew allowed people to stand in the back with their carry on luggage. Then after everyone boarded, they had to go to the front to gate check their luggage because there was no room for their bags and then they returned to their seats...such a waste of time when clearly the overhead compartments were full when they originally boarded.

The new planes (American Eagle) are beautiful and especially comfortable. The flight attendants are consistently professional and courteous. And, while it may seem inconsequential, the new liquid tube of coffee creamer—in contrast to the powdered coffee creamer—makes all the difference in a cup of coffee.

Cleared standby and gave up my seat. Terrible policy and boarding experience
