I think Southwest is the number one airline that anyone can fly I have flown for the first time Frontier and what a joke and their customer service United was a very strange experience I'm only sticking to Southwest from here on out for sure

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

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

Was fine, delayed and feels like southwest is always late

The entire experience from boarding to landing was amazing! The crew were very friendly. Will definitely be back.

Delayed flight, lack of information, boarding process is a mess as is the carryon luggage causing issues when leaving the plane….just a poor experience.

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

The crew was very kind and made going to Hawaii relaxing and fun to look forward to! Thank you Southwest for a pleasant flight!

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

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.

My flight was delayed by 4 hours in 30 minute increments. The gate agents were amazing but the communication was not. We were told that there was a maintenance issue but they didn't know what it was. That didn't inspire confidence. Then they said they found it and it was fixed and the pilot just needed to sign off. Then the pilot needed to talk to the other pilot from the arriving flight and we'd be fine. Then we were waiting for the pilot to call back. Then the maintenance issue wasn't fixed. Then they decided we were getting a new plane (why didn't they decide this earlier??). Fine. But then they announced we were changing gates AND terminals. And we were boarding in 20 minutes. So we all had to run to the new terminal gate. We could have taken off at that time, but we then had to wait for all the people who rebooked on a different flight to book this flight again. That took 30+ minutes because there was only one gate agent. When everyone ditched this flight, I saw it as an opportunity to upgrade to comfort. Delta, the greedy jerks they are, charged me $121. After their delay, their fault, their issues, couldn't even discount an upgrade. They only handed out $12 meal vouchers for the delay. I can't even get a snack from starbucks for that.

Much better than Latam, the worse airline company ever. I hope I don't have the need to fly Latam ever in my life again.

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.

It was terrible, if they ran flights on time it would make a big difference.

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

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.

Everything was great but the difference in paying for comfort + did not seem worth it.

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

My service dog and I were asked to deplane just before they closed the door - clearly very last minute they couldn’t find the documentation that I have filled out many many times before that is for flying service animals. I purposely purchase 3seats (a whole row) since he is large and not all passengers want to sit next to a dog on a cross country flight. The plane departed with my husband on it!!! They made me fill out a hard copy of the same form and had to reschedule me on a later flight where they could find 3 seats together!! I’ve done this so many times before - clearly the error was on their part in a technology glitch - but really people - do better!! Very traumatic - and my husband had to wait for us when he landed ….so bad. Poor pup was confused and tired.

Super friendly with lots of drink options an entertainment. Friendly crew.

I like flying first class, and United has a nice one

United airlines has the best customer experience from booking to arrival. I always fly United airlines. The mileage program is excellent

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Plenty of room for me and the cat in Premium Economy. Seat was comfortable. Boarding was a breeze. The lady at the special check-in desk was great, super helpful and professional.

Excellent staff helping my 96 year old senior promptly with her oxygen needs

This flight was 2.5 hours delayed due to crew issues. This meant that we arrived after 2 AM. Very very inconvenient and we were not really kept well informed.

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

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.

Same plane as RDU to LGA — internet not working. Pilot issue of some sort at end of prior flight - I was on same plane for my connection. Late/delayed —

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

I was in last row so that is never great bc the person in front of me leaned his seat all the way back into me.

Half of the TSA checkpoints at PHL are closed. Also, there is no standby for first class passengers. You can only standby for coach. Very dated policy and inconsistent with peers.

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.

Red eye from LAX. The most uncomfortable First Class seats I have ever experienced. No blankets or pillows. One bag of chip-like objects and two beverages for the entire flight. It felt very stingy.

Boarding was quick and efficient. The flight crew were friendly. There were limited food options available on the flight. The pocket guide said there would be salad and sandwich sections available on flights over 3.5 hours. The only food available were snack boxes. And those were limited as well. My flight was over 5 hours. The entertainment system worked well. I had both extra legroom seats and regular coach seats. The seats were not very comfortable. The entertainment controls in the armrest made it difficult to rest my arm without changing the channel on my neighbors TV. Overall, my experience was mediocre.

Entertainment and wifi were very sub-par - audio issues and no wifi

I was denied a plastic fork to eat my food and was told plastic forks are for paying customers who buy Jet Blue’s food. So I had to make a utensil out of a cup so nourish my body. Like a refugee. Because decency is dead.

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.

Rude crew member. She seemed annoyed at me without me saying a single word. Also loudly admonished me for having my bag next to my seat instead of tucked away before landing. Just telling me to put it away and guiding me without giving me a lecture would have been enough.

The check in and boarding process was a bit of a cluster. Two people at the counter to check in, three random lines that nobody knew which was for what, and people kept getting shuffled from one line to another for no apparent reason because then they’d get shuffled back and end up getting out further back in the line than they were originally. I only had to hand my already checked bag over and it took 45 minutes. I was never assigned a seat so when I tried to board I was pulled out of line again while someone had to try to manually assign me a seat. During the flight I got up to go to the bathroom, and there was an attendant in the aisle offering pillows etc and it was a 30 min wait unbuckled standing by the bathrooms because she said I couldn’t go past her. First and last time flying jet blue to be honest.

Great! I love Jet Blue. My favorite airline! Very efficient, clean and timely.

Always like Jet Blue! It seems, however, that people are getting bigger & seats are getting smaller! We had a very full flight and I couldn't get an aisle seat like I always do. I wish there were more leg room. People sitting next to me were very nice though so it was fine to disturb them if I needed to use the restroom. Otherwise the flight was fine but a bit long.

None of the in flight Direct TV worked. A better selection of Shows would have been better. The baggage was s low. Otherwise we enjoyed our flight!

Seat was surprisingly comfortable and roomy. I like the onboard “pantry”. Lavatory was kept very clean.
