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

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

Over a 3 hour flight. The turbulence was almost imperceptible except for 2 short periods which were not bad and over quickly. The attendants claimed "Safety first" and sat looking at their phones for 3 hours with no drink or snack service. This isn't the first time with Southwest. I thinkit may be there new plan of operation. Oh, and it was June 18, Southwest's Birthday which offered free drinks. NOT.

Flight was delayed, full flight and I had to change gates. Southwest flights are always late later in the day.

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

It is southwest seat was ok. Not the most comfortable seat

Plz don't take away free bags and free seating

It was good. I wish you had gluten free snacks for my husband.

Seat were uncomfortable. Snacks were a bag of hard mix things.

Cramped seats. They are like sitting on benches. No lower back support. Very narrow aisles. Bathrooms are getting smaller. I am 5.4 and weigh 150. Barely fit in the bathroom

I liked receiving attention from aged and well experienced flight attendants. I disliked the non-gluten-free snack but I brought my own so I was OK.

They took all carry-on luggage from Groups 6 -9 - I was group 5 and waiting in line to board - they made me check my luggage too. That then went to baggage claim and delayed departure from the airport. There was overhead room in my seating area - Delta over reacted. Also, had a gentleman next to me that took up 1/2 my seat.

The flight was delayed and oversold. I volunteered to give up my seat for compensation. Thinking I could get a good night's sleep instead of arriving home at 2 am. It took over an hour to get the new reservation confirmed, three different gate attendants, and two red coats. It took even longer to confirm the overnight hotel, and when I arrived, the line was 45 minutes long, with two people checking in, and at least 15 people slowly, very slowly—no food except frozen convenience food, no coupon for food from airlines. Slept, headed back to the airport, and that flight had an equipment change and a gate change just as they were about to board. It took an additional hour to board as they cleaned the plane from storage.

Comfort Plus seat 11E seemed smaller than prior flights. The movie selection is good. Watched most of the most recent Tron movie. I'll watch the remaining part later as my movie is saved in the Delta Seatback Experience.

Service in business class was not impressive. I ordered coffee with dinner and then watched other people get 2 refills before I got my 1 cup of coffee, and only after I pressed the attendant button overhead. Furthermore, the seats in the forward cabin need maintenance on this 737-800: the upholstery is detaching from the seat frame, at least on the backs of seats 1C, 1D.

this crew didn't care much. bumping carts into seats more times than i care to remember

Easy boarding with an extremely kind attendant. Seats were spacious and we had 3 seats for 2 people so we could stretch out. Comfortable air flow and very attentive and hospital attendants. Bathrooms and food were the only negative. Bathrooms were so small you could hardly get in and close the door. I don’t think an obese person would fit or a person with a movement disability. Food was the trending food for flights, nonexistent. We spent $40 getting sandwich and snack at airport for our 6 hour flught.

It was a great flight and the stewards and stewardess were all kind and accommodating!! The seats were comfortable and entertainment screen excellent!

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

Seat back monitors and outlets were dead and not working.

The flight was delayed but we got to our final destination.

Always pretty good as far as I see it. Staff was friendly and process was quick to get on and off.

Lost one piece of luggage even though I checked in 2.5 hours before the flight

Horrifying Almost 2 million miles. Bring your own food and drink. One coffee or drink every three hours. Have to order meals on app more than 24 hours ahead Tiny and dirty bathrooms

Seat pitch is horrible especially on the 15 hour flight. Gate crew at SFO was Outstanding. The flight crew was also great.

They delayed the flight from 9:00 to 11:55 At 11:45 they canceled the flight. I paid a premium price for the tickets with poor service

Smooth flight, especially take off and landing, and great crew on board. Really loved the stroopwaffles!

Our seats were all the way in back of the plane,

My window shade didn’t work. So I missed coming into my city. ☹️

Delayed a day due to snow storm. Was upgraded. That kind of made up for significant delays from FLL to COS with no compensation or acknowledgement.

Good. The wife was not working but then it got resolved.

American was the airline that Starlux contracted for this trip. I arrived in time to make the connecting flight on American, and then the baggage-handler debacle happened. For some reason, the first class and premium economy passengers' luggage was unloaded first. Never seen this happen before. They had handlers removing the bags from the carousel for those passengers. Meanwhile, all of the economy passengers were waiting for their bags, including me. And there were a lot of bags because it was an international flight packed full. While waiting for 45 minutes, my bag didn't show. Meanwhile, an American representative showed up asking if anyone has a connecting flight to Phoenix. Of course I spoke up, and they proceeded to try to find my bag because I had to take a bus to the actual terminal to catch my flight. Which I was not informed of before I arrived. After another 15 minutes of searching, my bag was finally found with the first-class passengers' bags because they had pulled it by mistake. So I rushed to the terminal with the American representative to catch my flight, and they informed me that I missed it and could not get another flight until the next day. Of course, after being on an international flight for 18 hours, I was in no mood to hear this. Now, to be fair, there were a few American employees who tried to help me. After hearing about the missed flight, they got a supervisor to talk to. I expressed my situation to the supervisor, and she was not helpful until I asked for compensation. She agreed to get me a hotel room for the night. So I agreed, and she disappeared into her office, and I waited. And waited. And waited. And waited. While waiting, I was asked by three different employees who knew of my situation if I had been helped. I told them I was waiting for the supervisor to get the hotel room, and they said they would check. Finally, after waiting for 75 minutes, one of the employees who had asked me if I had been helped arrived with my hotel room and arranged a ride to the hotel for me. Never saw the supervisor again. It was now 8 o'clock; I arrived at 5:45! My rebooked fight was scheduled for 6:11 this morning and I have now been informed it has been delayed until 10:00. So am I happy with American? NO I'M NOT!! ;

Horrible experience, delays after delays. A flight that should arrive 11:50pm just landed past 1 am, and another 30min waiting for the baggage to come out. Very disappointing.

Ontario airport boarding was very easy to park and access, is clean and TSA took 10 minutes total. Check-in was a breeze and cruise was very nice.

Good flight, seated and had a water within 5 minutes. Crew was hospitable.

The flight was on time and arrived early. The crew were friendly and helpful.

The chair cushions may need an upgrade. I have been noticing they are so worn out, thin so you’d sit in a dip 😄. Other than that, all was an enjoyable trip. Thanks AA!

Everything about the flight was lovely…We left early, arrived early, cabin crew were efficient and helpful. Flight was easy and most pleasant.

The flight left a bit late, but arrived close to time expected…With the flight being close to full the crew did well serving drinks to all in a very timely fashion. The flight was a pleasure…

Flight delayed 3 times. We were directed to go to a gate across from our gate. The plane wasn't there yet so we had to wait for it to arrive, then deplane everyone and then wait again for the plane to be cleaned. After 45 minuites we were allowed on the plane. The first plane had mechanical issues. The 2nd plane must have had bathroom issues because we did not have any food service whatsoever. No snack or beverage. That made for a long time not to have anything considering that we had just made it to the original gate and we had no time to stop to get food or a drink. Then we didn't want to leave the gate to get food because we wouldn't know how much longer the delay would be. Then the next gate change. Had we been told that the total time would have been aprox 45 min later we would have left to get food and a beverage. We had to wait again for the okay to the pilot to take off so we were on the runway for another 20 min. Overall, we were delayed over 2 hours which felt like 4 hours.

From the moment I walked into the airport in Chicago to the moment I was walking off the plane in Florida I had an unforgettable experience! I was traveling with my 3 month old by myself and everyone just made sure I was taken care of. I couldn’t thank them enough!

I usually dont fly JeTBlue and I dont think I will ever do it again. The flight was delayed fee time, nobody was giving us any info at at the airport, gate changing, the slowest and poorly organized boarding ever, rude staff.. huh

Like the variety of entertainment options. One crew member was a little on the rough/rude side. Boarding was a mess, attendants didn't do a great job of helping with the luggage storage and it delayed us a couple of minutes.

I liked the punctuality, the crew, and overall the whole flight

When I agreed to give up my two seats because of overbooking by the airline, I should have been offered some sort of reward or credit towards a future flight. I was not. It was not until the next day when I mentioned it to a Jet Blue employee that I was advised to call 1-800-JetBlue. So here I am, having done Jet Blue a favor and I had to do the work to find out if I was going to get a credit. Such service

It's not JetBlues fault but there was a smell on the plane (possibly other travelers) and 3 children behind me that never quit whining. Soccor fans that were very loud. Pilot brought the plane down from high altitude quickly, dropping us hu dress of feet at a time. I've never felt that intense of dropping on other airlines (usually fly Southwest Airlines). But I arrived safely and I'm thankful for that.

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.

The aircraft was fine, it’s was just the service. The flight got canceled several times and that was very inconvenient for my 69 years old mom.

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).

They put me on a chair in between two men, one overweight who was almost falling on top of me, and the other was even uncomfortable because I was half falling because of what the other was pushing me. I stayed with. my feet were swollen from fluid retention and from being unable to accommodate myself. it was very uncomfortable. I asked for help but they told me that the flight was full and they couldn't help me. I got off the plane almost unable to walk due to the inflammation. and then at FLL airport I asked for help because I couldn't go to my next flight, which was a connection.

I really liked the way snacks and drinks were available throughout the flight!!! The flight attendants were also all fantastic!
