Temperature was very cold. seat was uncomfortable bc headrest did not work properly - the earflaps would not move.

Alaska airlines was good! Friendly staff, good communication and respectful. The alaska airlines help in everyway they can

The person sitting next to me did not fit in one seat, so I effectively only had half a seat to myself. Airlines should come up with a strategy to sit oversized people in a way whereby they are comfortable but don't disrupt or take over other people's seats. It's unfair.

Very below what I expect from Alaska/ On Feb 19, my foight JFK to Portland Flight was three and a half hours late leaving JFK (NOT due to weatherat departure or destination) In addition to losing this time, I then had to take a taxi home, rather than public tranist due to the late hour. This added $45 to the cost of the trip.

Alaska Airlines is always my first choice for airlines. This flight in particular was great because we were all boarded quickly, the staff was friendly, and we arrived at our destination early.

Packed flight. Excellent crew. Served snacks twice all very efficient and polite. Even the lady that checked in our bags was so friendly and pleasant

a 56 flight should ls offer a light snack other than pretzels and a tv or movie

They assigned me a seat last row where seat can’t go back. During online checking could change seat for $130!!! Others who got assigned at gate got better seat free!

The flight was on time and the crew were friendly.

Many gate changes and delays once in Seattle for the connecting flight.. Should load back of the plane first. It’s common sense.

Flight was on time. The crew was efficient and kind.

Did not like the fact that I was charged to take on a bag I usually put in the overhead

My flight was delayed, not by much.?very good communication during fest and waiting to board.

Communication with airline electronically was difficult. No number seemed available to talk to customer service.

What could have been better is if Discover credit card would be able to purchase food

Crew was inconsistent in instructions in advising passengers about seat backs during take off. Perfunctory announcements except from cabin.

The experience with Breeze was really great. The app makes managing flights easy. You can check in on there 24 hours in advance, and your boarding pass is there, too. The flight crew and the staff at both our airports were wonderful. Snacks and drinks were reasonably priced. The seats were very comfortable, they even had adjustable headrests on every seat. The only downside is not having entertainment or Wi-Fi available onboard.

The price is amazing. I was worried about how the flight would be as I never flew then. Seats were very comfortable. We had lots of legroom. The Akron airport was really nice. Overall it didn't have the stress we usually experience with flying. Highly recommend

Flight delayed and moved to another gate. Got a text message updating the gate as final boarding finished. Missed flight, fighting for my refund

Prior to boarding we were told the flight was still on time up until about 20 minutes after the scheduled departure time. Details on the new departure time and gate were not provided to us in a timely fashion and we were lead to board a flight to Pittsburgh only to realized upon scanning my boarding pass that it was the wrong flight when signage at the gate said Providence. However, once on board the plane was comfortable and staff courteous and nice.

Seats were broken in premium select and so was monitored on my seat and other people around me

Boarding was a sh!t show. JFK BOARDING was awful. The agent called three sections at a time Clogging the area then yelling at people to not block the walk way. How are you going to call delta one , premium select and comfort plus at once and the yell at highest paying passengers. Need to do a lot better and the flight attendants in the galley need to understand that their voices travel. They were talking about others and everyone in the cabin heard them

The main person that was coordinating everything was a short white/light skin Spanish man and he was very rude. It honestly made me feel like it was everyone’s First day at work. His announcements were very not reasonable and they did not make sense. The stewardess on the flight that made the announcements she didn’t even know what she was talking about she sounded inebriated. There were no snacks or drinks on our flight there wasn’t even much turbulence. This flight was not enjoyable nor was it what a Delta flight should be and just this past week I flew with Delta 3 times.

The crew was horrible. Cleo was the most unwelcoming flight attendant I’ve ever had.

Do not get fooled by the term “Delta One” flat bed! The seats were super narrow. The ottoman for the feet was so narrow that when you recline the seat in flat bed position, you can only fit one foot in the 8” width space. There was only 1 flight attendant for First Class. The breakfast took 2 hours to get served. Instead of offering French Toast, the served bread pudding. The champagne with orange juice or Mimosa tasted terrible. Almost all the movies offered were ridiculously old. For a long flight from San Francisco to NY, it was frustrating! I DO NOT RECOMMEND this flight!!!

It was a very smooth ride. Not sure on a flight departing at midnight can be much better but it was late arriving and I had an early day so really just the logistics.

The plane looks and feels like we are traveling in a 3rd world country airplane. Dirty bathrooms, horrible food, old and uncomfortable setting, my son’s little table was broken, the chair would stay recline, an so on.

Crew handling the boarding at the gates are quite aggressive with the passengers and must be given training/ refreshing courses to improve customer experience.

Fix the technical issues before departing the airport. We had no entertainment and inflight wi-fi due to technical problem. Imagine up in the air for almost 6 hrs on a cage!!

Pros: "Easy boarding. Good entertainment. Didn’t bother me too much."
Cons: "Better good. More comfortable seats"

Everything was good except for deplaning in NY. Took way too long!!

Jet Blue keeps getting iit wrong. 4 hour mechanical delay followed by terrible boarding experience. This is my third horrific jet blue flight in 2024. I am going to try to avoid this loser in the sky

After we landed, we were held on the plane for 30 minutes. There was no one at the gate once we landed and we forced to sit on a plan that had already over an hour delayed.

Flawless trip. Pilot came out and introduced himself, welcomed everyone, made a light joke to put everyone at ease. Arrived quite early.

JetBlue's check-in was great, but there was an in-flight flight attendant who was very rude and unkind. I didn't realize that the bathrooms were already locked 30 mins prior to landing and needed to use the restroom. Instead of politely asking me to return, she rudely told me, 'No, bathrooms are locked! Go back to your seat!' The flight was more than an hour delay, which made me almost miss my connecting flight. I understand the reasoning, but the action they took to get a hold of maintenance was time consuming. It took them so long to get a hold of maintenance and for maintenance to get started. Most importantly, my 3 checked baggages are missing! I'm writing this review 3 days after my arrival to the Philippines, and my 3 checked baggages, where my wedding dress is, are all missing!

Safe takeoff and landing Better snacks and coffee. Headphones for the TV monitors.

I didn't like the 2 hour delay and then mechanical issue once we were on board.

Long flight but food was good, with free pillow and blanket. CREW WAS GOOD.

For some reason, the seats on this flight seemed unusually uncomfortable. Speaking with friends who took another JetBlue flight later in the day, they brought up the same issue.

JetBlue has really gone downhill. They have all the problems without the discounted price. If you need to get anywhere in time, this is no longer the airlines for you

May never fly American again Delay in take off WITHOUT EXPLANATION Cabin freezing Crew NASTY entertainment did not work entire flight

It was wonderful upgrading to first. Plane was so cold thou. Crew was great. Wish there was a food option in first for such a long flight. Doesnt matter the time of day. Chintzy.

Crew was rude and the flight is not comfortable for long haul.

The flight was so short that the lack of leg room didn't bother me for long. The plane was smaller so only two seats per row and there were chargers. However, they didn't serve any snacks.

Horrible trip. I won't fly AA again Boarding was a nightmare because they squeezed people into the waiting like sardines. My connection was 30 minutes and the run to the gate was horrible. Then the flight was canceled AFTER boarding. The Flight attendants did not know what to do and gave out the wrong instructions. They finally sent us to a different gate. Again, the waiting was like a sardine tin. The flight was okay and my baggage arrived fine.

I will never fly again with AA seats suck. No power ports food was like a shelter trash

I have lost my items and I didn't receive good customer service

Their delay caused me to miss my connection with a twelve hour overnight delay that was terrifying

Impossible d'ajouter des bagages avant l'arrivée à l'aéroport. Obligé de le faire au dernier moment.

Had to gate check bags, even though was empty spaces in overhead bins. No entertainment.
