It was friendly. Also, we had some turbulence due to the wing of a plane in front of us, and I was grateful the pilot explained that reason to us. It made me feel like we were safer than if there were no explanation and it was inherently interesting to learn.

Our original flight was cancelled and we were rebooked on a flight the next afternoon. Finally gotten it straightened out at guest services and we were able to get on a delayed flight that departed about an hour later that our original flight. The Guest Services and Gate staff were very helpful!!

Wonderful except my seat cushion had no “cushion” left Cs. It was quite hard and I’m very petite and can us some padding on my back side lol. Other than that we were very happy.

Smooth boarding process and comfy seats! Will definitely fly Alaska Airlines again!

Stop with the fake cheerfulness and the too often expressed sentiment that all you care about is our safety. Bull…. You use that as an excuse to keep us cowering in our seats. How about you go back to the old standby of telling the truth… like why you overbook, why you are delayed, why we don’t get vouchers for your screwups.

No communication on fact flight was delayed. Sat in sweltering plane for 45 min without explanation. Sat on airplane without explanation again after landing.understand delays happen but lack of communication and concern for my lost time was disappointing

Very good. Plane was newly renovated so everything was very clean

My first leg was canceled 3 hr before leaving. My return trip left late. I leave it to Alaska higher ups to figure out what can be improved. Just put yourself in the passengers position.

This flight was miserable. Initially delayed due to weather in Las Vegas. Gate staff did not explain it was due to weather, blamed air traffic control which is harder to understand as it was a scheduled flight- ATC should know we were coming and the landing slot should have been secured. Airplane on the ground for 3 hours in San Diego. Then when the pilots got on, it required maintenance. Could have figured that out hours ago. Then when we got on the plan, pilots had to switch out which further delayed us. New pilot spent some time talking on the PA- wish he would have just gone up and flew the plane. Got in the air (finally). Then they canceled in flight service (they had time to serve, it was just an ERJ). Southwest serves a whole 737 on this route pretty much every time.

Several gate changes and then the plane kept getting delayed. The delay is understandable but this constant gate change I think twice or three times is just ridiculous.

I liked how it boarded fast. I do not like how the seats are just too narrow, and I’m not a big person.

had to check bag at gate when there was still overhead bin space. As usual the WIFI didn't really work.

Red eye from San Diego. Temperature of the cabin was way too warm and the air duct flowed very little air.

Great job Southwest! My family doesn't fly often but we felt safe the whole time.

Comfortable. Easy. No problems. Just wish they had gf options for snacks.

The charges were ridiculous for an hour flight and the turbulence was very scary.

The seats are now more narrow. I paid for front row the seats in the front are even more narrow than before.

The boarding and seat assignment system no longer works for me, but I know it is being replaced. Otherwise, I am good with the overall experience.

San Diego airport is brand new, spacious, airy and very smooth checkin at SW baggage drop.

No trays in our seats, we sat in first row, purchased a business class fare. Had to hold our drinks and snack in our hands. No plugs for our cell phones. Had to pay for it a drink cocktail each. Seats so uncomfortable.

The only issue is that the plane was HOT. This was not the case on my first flight so not sure why, but thankfully I had a portable fan with me. Everything else was great!

Seats were old and very uncomfortable. Coach seating is way too tight

Flight was delayed at airport with large backlog and WiFi was spotty

Flight was delayed from San Diego due to being overweight for weather conditions. We missed our connecting flight to our final destination due to the delay, as well as the connecting flight leaving before the scheduled departure time. We missed the connection within 10 - 15 minutes. We were booked on a later flight arriving 7 hours later. There were 7 passengers sharing the same originating and connecting flight.

Horrible, mismanaged ground issue resulting in a long delayed, next flight left early, waiting extra 7 hours in the airport, screen did not work

The internet on these planes stinks. Need to get starlink

Very good flight. Crew was great. No issues and we even arrived early.

Loved the crew! Sucks that we went from 1 hour and 8 minute layover to a 3 hour layover. But weather sucks like that.

Delayed flight (1hour) plus a long layover after an overnight flight with no backup plane available.

Crew was excellent. Comfort seats not as nice as other kinds of planes.

Entertainment was great. Seats were good. They did not have my pre-ordered hot food product available but did comp me something cold in place of the item.

Flight was on time, clean, etc. Despite connecting to your wi fi I was unable to use your app to watch entertainment.

The back to back mechanical delays from Denver to San Diego and then on my return flight from Denver to Great Falls it added extra time both ways

Service was professional and quick. Premium economy seat was comfortable given the class

The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future

Over 2.5 hour maintenance delay on first morning flight with no acknowledgement, compensation or even gesture of good will. Aircraft had overnighted at airport so issue should have been addressed prior to boarding. Over 3.5 hours before first slow and deliberate beverage service.

Complimentary light meal would be appreciated. But great flight crew service on all legs

I was in first class. The outlets at my seat did not work. The plane was shabby and run down. I had prepurchsed a day subscription for internet that was not redeemable. I had to repurchase the internet for my flight and then it didn’t work anyway. Quite disappointed in what was supposed to be the launch of a great vacation.

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

Flight was ok. Unfortunately it was a Boeing 737, which is a cramped / tight airplane. I prefer the Airbus as they are a more comfortable flight experience.

They lost my luggage and have ruined first day of my vacation. Still don’t have it. I have nothing. I also paid for a seat I did not get. They changed both our seats with no notice. Will never fly this airline again.

Flight was delayed 3 hours. No food on plane besides snacks

I have flown Jet Blue many times between JFK and SFO. I appreciate how clean the planes are, the ability to select my onboard entertainment and the flight crews have always been amazing! Unfortunately, my trip from SFO to JFK on August 23 was unusual. I arrived early at SFO for the 12:00 noon scheduled boarding. The flight was supposed to take off at 12:45pm but after sitting for a while, the plane had to return to the gate to have a generator inspected. After deplaning and then reboarding, we eventually took off around 3:30 pm. It was explained to the passengers that because the plane was using a backup generator, additional fuel was needed and the flight would take longer than originally scheduled. We were originally supposed to arrive at JFK at 9:32 pm but instead, arrived at midnight. Unfortunately, I was exhausted for the funeral I attended the next morning. As a passenger, I have always expected that the plane will be in good mechanical order and that all parts will function as expected. I'm not entirely certain that if I fly Jet Blue in the future, that I will have the same level of confidence that I had become accustomed to. Thanks for the opportunity to provide this feedback.

My screen didn’t work, my seat didn’t recline, the flight attendant was rude and completely dismissive, the airplane was freezing, the seats are way old, slanted and uncomfortable. I payed for a full ticket and got a horrific experience, with a flight attendant who dismissed me even though I was calm respectful and polite.

JetBlue cancelled the flight. We had to rebook on another airline.

The flight was on time the crew was courteous that makes for a good flight.

The seats were roomier than other airplanes I’ve been on.

Seats were great, the staff was great, and the food was about the best I've had on a plane, and is especially the best of any US-based carrier I've flown. Free Wi-Fi was also great.

It was inexplicably canceled and we are stuck in LA, haven't gotten home and it has been an inconvenience having lost work (on unpaid leave for my husband).

Flights with JetBlue from San Diego to Boston are a miserable experience. The flight was delayed about 1.5 hours due to “weather” supposedly but the flights for other airlines left on time so it just have been some kind of weather that only affects JetBlue. I had a small carry on - purse. The crew stored it in a bin 2 rows down from me because they were using the bin next to my seat for other people’s stuff. The TV screen in the emergency row seats does not work. It just was awful from start to finish. When we landed, we had to sit inside the plane for a very long time because the plane had to be moved to a different gate.
