The agent changed my seat and upgraded me free. The flights are ALWAYS delayed. We sat there almost an hour while the plane was held for 4 passengers. I was then unable to make my connecting flight. This is why I dont fly alaska unless there are no more flights with delta

The agent changed my seat and upgraded me free. The flights are ALWAYS delayed. We sat there almost an hour while the plane was held for 4 passengers. I was then unable to make my connecting flight. This is why I dont fly alaska unless there are no more flights with delta

The flight was on time and got in early which allowed us to get to our next flight.

The plane not having any overhead bin space was inconvenient. Anytime my luggage has to be checked it ends up covered in scratches and that’s not covered by the airlines for replacement/repair. The WiFi did not work or was not offered for the flight from Seattle to Vancouver.

Most of it was good. The flights were on time. The staff were helpful and friendly. I had a short time connecting flights and they let me deplane first and I made the connection. On the outbound from DTW to SEA I was seated in the middle of two very large people. I am petite and even with my arms crossed they were both hanging over into my seat touching me. The meal had way too much pepper and spice, my lips were burning. Other than those two issues, I was pleased with the service and the trip and will use Alaska Air again.

Wheelchair assistant was on the spot, and very helpful. Gate agent was kind, and made sure I boarded the plane without having to try to hurry with my painful hip. My seat was so comfortable, 20A. I am tall, 5'9 and I need to stretch out my legs due to chronic nerve pain in my back that runs down my right leg, in addition to the bursitis in my right hip. Alaska air has the best economy seating in the market. So much room for legs, elbows, etc. When I arrived in SEA, the next Wheelchair was waiting to take me to the next gate. Great communication.

I had to cancel my trip due to health reasons three days after making the reservation. I was stunned to find out that the ticket was not able to be credited for future travel. $734 loss. Not happy that this was not my experience with Southwest Airlines. I will stick with SW in the future. Boo Alaskan Air and Kayak.

The staff was extremely helpful and accommodating. The only thing I could have done without was the long layover in between flights but I was going to a less popular destination so it was understandable.

All went well, right on time, easy boarding. We ordered the evergreens grain bowl and were surprised and pleased how adequate it was for vegan lunch! Landing was smooth and gate exit was easy

My seat and tray were filthy. Someone’s used straw was in the seat pocket and there were coffee stains and food crumbs on the tray table

On time, good boarding process very quick. Clean planes. Planes are tight, not much leg room ( i am only 5'8"). Some attendants are moving through aisles fiercely and pushing passengers. Got yelled for a tiny man bag that it is an extra personal tem ( size of a wallet) Wi-Fi on the plane does not work well with android phones.

The crew, and fellow passengers, were super gracious and kind. There seemed to be plenty of bin space even though the plane was full. It’s nice to get a glass of wine with dinner in Premiere seating, and there was a lot of food.

First flight out and was 85 minutes delayed. Notification came out way too late

Delta flights recently are always delayed AND at jfk tney get the gates further away (need To walk 20’ to get to them/all the way at the end of the terminal). Not sure whats happening but price doesnt match experience!

Everything I mentioned earlier - the airbus was more comfortable indeed and the experience was further enhanced.

Delta continues to set the benchmark for traveler-friendly service with minimal disruption and clear communication within the mainland US (coast to coast). I am consistently pleased to be a Delta customer, and this experience once again met my expectations. There was a brief delay departing from MIA due to a technical issue that required the aircraft to return to the gate. However, the situation was handled professionally and transparently. Fortunately, my planned layover allowed ample buffer time, so the adjustment caused no stress. Overall, another smooth and reassuring experience.

Good experience and the flight landed early. There was no food I had or entertainment.

Flight was delayed and no reasons provided. After the passengers were boarded, the crew made announcement that the captain has jot arrived and he would take another 15 mins. All passengers patiently sat until the captain came and started. Terrible experience!

Flight was delayed. No information on why it was delayed. After we boarded the flight, , the crew made announcement that the captain hs not arrived and he will take 15 mins more to arrive. Passengers were just sitting patiently for the captain to arrive and start, Terrible experience.

Totally worth the miles to upgrade to Delta Comfort. Plenty of legroom.

This was my first time flying Delta ever and I had a great experience!

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.

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.

Very good. Nice plane and we sat in economy plus - bigger seats, more room. They served a meal and snacks, and the meal was an apple stuffed pancake that was very good! The snack for us was a hummus sandwich - also very good. The flight attendants were helpful and nice. They have plenty of movies and shows to watch. My only negative -- they changed our flights around and did not adjust the layovers, so we ended up with a very long and unnecessary layover in Honolulu.

I liked the Starlink WiFi but didn't like how they said they were the only airline to offer a free meal and it turns out to be just a standalone sandwich and then charge for snacks to go with it. Rather have the free snacks like Southwest, but have the option to purchase a decent meal for a 5+ hour flight.

Flight scheduled to take off at 5.55pm but it did not take off until 7pm due to some food delivery delay.

Unfortunately, I was put into the middle seat in the first row of premium seating. Sounds nice right? No! that is the worst seat in the plane. I wish I was in economy rather than be in that seat! There is no seat back pocket, no tray table, no charger. Nothing! so unless you're row mates are willing to let you share their basic amenities any flyer should have, you are stuck. It was the worst experience ever! And the flight attendant forgot to take my drink order. I felt like the forgotten flyer.

Delayed and cancelled flights were hard and very stressful, both ways!

As great a red-eye flight as red-eye flights can be.

Very old flight - time to retire it for newer airplanes

2+ hours delayed Outlet in row 12 did not work Tv monitors did not work Lights kept off the entire flight for at 5pm-7pm flight

Very disappointing given gate agent behavior. Filed a formal complaint with United.

Do not like the size of the overhead bin. I think staff should monitor the size of suitcases that are being carried on by passengers to ensure they meet the size requirement.

Crew was great (professional, attentive, prompt). Snacks for 4 hrs flight is deplorable.

Flight delayed. WiFi connectivity very poor if not existant. Last minute arrival forced me to run to catch my connection.

Both of my flights arrived early and check in process was smooth

Terrible. No customer service, no food, no drinks on a 6 hour premier economy booking.

Short flight, but no drink/snack service. The flights both going and coming were delayed.

No Snacks or Entertainment. The flight was short, snacks should still be given.

We lost a day of our vacation because AA did not get the plane to the gate on time. Even though the gate attendant was very clear that it was not weather related, AA would do nothing because there was some snow that day. They basically said the gate attendant was wrong even though she was on the front line of the situation and they were not.

See prior comment about how Kayak mishandled my reservation and delayed my arrival by 6 hours.

American Airlines was great and worked very hard to change my ticket so I could get an earlier, direct flight back to Dallas. However, I was informed that Kayak made mistakes with my itinerary and classified my ticket as desiring to be on the earlier flight instead of taking the necessary step of calling AA to get me on the standby list. This ended up keeping me from being added to the standby list and delayed me getting home by 6 hours. I am happy to discuss this further with Kayak so they can correct their procedures so this won't happen again.

The flight was fine. It's the satellite terminal that supports American eagle flights is what sucks. There is only one food option and everything there is way overpriced. I mean I know it's airport pricing, but it's even crazier than that. I bought a sandwich in a plastic container for $18.

Overall it was a good flight. Because we traveled on a Saturday we were upgraded to FC since my wife and I are both Executive Platinum. The only areas for improvement we noted are better snack assortment and perhaps a little nicer plane as American is flying some older planes now. Everything else on this flight was excellent, which is frankly not the norm for American since we have had multiple issues on prior AA flights.

The smell from the bathroom kept wafting through the cabin. It made people sick.

The flight was really crowded. Flight attendants were just ok.

Boarding delayed 20 minutes for no reason, no wifi, in flight entertainment, or snacks / waters?

Didn't get a seat assignment until the last minute even though i picked a seat.
