Southwest has been a nightmare. Delayed flights, missed connections, systems down. Never again am I flying southwest.

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

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

OKay. I sat in the back of the plane and it was really loud between babies and little kids, and adults who.like to talk a lot and loudly most of the flight.

it was a short flight, so no refreshments. Could've used some water since I was running from the end of one terminal to the end of another to catch this flight

Easier that prior flight. The airline attendants didn’t really do most of their job as I noted in prior email.

Would like to have screens on back of each seat for entertainment.

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.

The flight attendants were really nice, and of good spirits. Gave all of the safety announcements with a bit of humor and friendly reminders. Easy boarding even as an early c group passenger. Aisle seats available in back of the plane. Coke products and snack mix available. Love the free bag check.

The staff and attendants could have been more helpful with storing carry-ons above in the overhead compartments as well as helping passengers find available seats. There was no food/beverage service due to turbulence There was no internext connectivity due to turbulence The boarding process should be changed entirely and seats should be reserved or assigned to expedite the boarding process.

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

WiFi was a major problem and if it does not work on a 4 hour flight then that lowers the overall experience

I was impressed with how quickly the baggage transfers were made.

I upgraded to first. Quick and easy boarding. Comfortable seat with power and a nice IPA.

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

737-800 in first class was pretty dumpy. Seat had an uncomfortable angle, storage under the seat was blocked so even my very modest backpack didn't fit, power outlet was flaky. Weird tiny seat pockets that couldn't hold a gallon ziploc bag, emesis bag missing, etc. etc. No in-flight service due to turbulence. Crew was excellent, boarding was smooth despite a full flight.

Flight was delayed due to needing a replacement flight crew. Delta changed the aircraft type in Detroit. One hour delay. But once in the air, good flight

The flight was overbooked and the staff at the gate started calling for volunteers to drop out and offering incentives. That delayed the flight

There was no wifi even after my husband paid for wifi it wasn’t working. The plane looked and felt old.

Update the cabin with tv screens or at least music sources.

awesome team work seen since on board till off plane in my destination. thanks you so much.

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

Boarding, time to take off, in flight offerings, and staff were all great. I recommend using UA for this short flight.

This was an auto-rebook due to being delayed from an earlier UA connecting flight. The boarding was fine, but they sat me in a middle seat when my original booking was a window seat. Overall, the flight was fine as it still got me to my final destination.

The flight out of Fresno boarded 1.5 hour past scheduled and made me miss my connecting flight from SFO to SEA.

I missed the flight due to maintenance issues. This is the second flight I’ve missed in four days because United allows such little time between layovers. Very disappointing

My return flight to Honolulu (UA 1170) was on a 777-200. I’d forgotten the weird seating arrangement in first-class (2-2-2); I was in 1B, so I faced the passenger in 1C. Unfortunately, there was a problem with the flight computer, so we left LA an hour late (6:05pm). The meal I chose was Korean BBQ Glazed short rib. It was served with a nice salad and fried rice. This meal was better than breakfast on the outgoing leg. All in all, a decent flying experience. Ratings: 777: 3.75, food: 3.5, service: 5 (out of 5).

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

Tired of being nickel and dimed for every little thing, especially carry-on luggage.

Late start, late arrival and very uncomfortable seats. No legroom, no elbow room because the person next to me was fat. I had to press myself toward the aisle or be rubbing arms with them. As a result, I was bumped every time someone passed in the aisle. But I couldn't get away from the hip encroachment. Who wants to rub hips with an oversized stranger for over 2 hours? I'm not fat, just tall and larger-than-average frame so I need to leg room but it would be nice if other peoples' body parts weren't squeezing under and over the arm of the seating. Why should it cost me so much for simple comfort so United can get a little more profit?

Delayed and WIFI was not working for most of flight.

I am generally an American Airlines loyalist but this flight was not good. I was seated in an aisle seat and the gentleman in front of my had his seat fully reclined which made it impossible to work on my laptop, eat or drink.. The gentleman in the middle seat was watching something on his phone without headphones.

Disorganized boarding. Mandatory to gate check bags. Curt flight staff. No space for cabin bag, even when I was in first class.

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!! ;

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!

VERY disappointed at the agent checking in my luggage. I know that the weight limit is 23 kg, a little over 50 pounds (50.71 pounds). Yet the agent kept repeating "50 pounds". So I said, the limit is 23 kg, and she had the audacity to say 'no, it is 22 kg!" Imagine my surprise. Was she ignorant or was she poorly trained? Not sure. The boarding process was pretty good. The speakers were loud enough so I still could hear them despite inconsiderate passengers continuing to speak while the announcements were going on. During the flight, the teenage girl sitting behind me kept pressing her feet to the back of my chair. I turned around several times, yet she did not get the hint. I did not make a fuss since I sense I had a bad streak that night with AA, so I just did the best I can to lean forward and not let that bother me.

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.
