AC sub par. WiFi not working correctly. Ac sucked. Seats very narrow.

Near 4 hour flight with only 1 service. Had to use call button to request water. Internet and power not working until into flight. Internet would stop working during flight.

Southwest's seats are the least comfortable I have ever sat in.

The cabin was quiet for the redeye flight. The area was clean. The staff was great. The 787 Max was in good condition. Drawbacks were that the seat widths were tight for some passengers. The seat padding was at best average and for a long flight uncomfortable.

Southwest like most American domestic airlines, is a mediocre airline. But it is among the cheapest. Oh well.

My flight was delayed 50 minutes and we were rushed to board to then sit for 15 minutes until the pilot arrived. Unacceptable since we could have waited to board. Also the delayed flight was updated AFTER we boarded to more than the 10 minutes as originally stated.

Other than a bit of a delay, everything was good. Again, the boarding process and picking seats is the only thing I don't enjoy.

If we are going to have to pay for luggage, make it easier to do. Put something on the app during check-in so I don't need to do it at the kiosk. I've done it twice recently and I ended up having to pay at the desk because something went wrong at the kiosk in Tampa.

southwest just starting charging for luggage. hadnt realized it until it was too late. now out $70 when i couldve bought a carry on if i wouldve known. free bags was one of the only reasons i chose southwest over another airline (the other being no assigned seats, which is apparently also being changed). stupid business decision. wont be flying southwest anymore.

The quality of Southwest Airlines continues to degrade each time I fly with them. If it were not for the free luggage, I would probably choose another airline. Their prices are a little bit competitive, but way too high for the quality of the service. Southwest is not unique in this way. Domestic flight in the United States of America has continued to be a lower and lower quality product. Very sad when you compare the quality of domestic airlines to that of many international airlines around the world.

On this flight I felt the food offering was not as complete as on previous flights. The tomato salad was a bit off and there was nothing additional such a bread or butter. The breakfast was only one option, so you either ate what they had or ate nothing. The crew was efficient, but most seemed frustrated throughout the flight. The flight arrived early and was obstacle-free, so I’m overall quite happy, but the shine in the rest of the experience just wasn’t there.

Great flight with Delta! Boarding was quick and easy, the amenities were solid, and the plane was in great shape. The flight attendants had a fun, lively energy while staying professional. All in all, a smooth trip — even managed to catch up on some rest. Thanks, Delta!

De planning was an absolute mess. We were never told that we weren’t at the gate and that we had to go down unstable stairs and then hop on a bus. People were falling, we couldn’t tell who was in charge. Overall terrible communication that ended up leaving a bad impression at the very end of the experience.

For a 69 year old with health problems I had the worse experience, no wheelchair when I entered a lady told me to sit and wait while a gentleman told me I had to walk to the Delta station, which I did. I had a carry on and a bag, and I was traveling with my service dog, which was on his carrier and the lady charged me for my carry on luggage, beside all the waiting cause of the delay, I had to walk to get my luggage cause no wheelchair showed up, I am so disappointed. I will get in touch with the company. I got home at 3:00 am, not good for my health situation.

Food was surprisingly good but the WiFi was not great

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.

My flight was canceled after being rescheduled for four days canceling my trip. Kayak and everyone affiliated with it I.e the airlines, and just fly have been excruciating to deal with. My trip to visit family had to be canceled as there was no way to make it. I am furious at all of you.

They delayed our flight because of bad weather in NY which was completely understandable. Then they cancelled our flight and a later flight that evening. The earliest we could fly was the next morning. We ended up buying last minute tickets on another airline and made it home slightly delayed but safely that evening. Delta kept saying it was weather related but if that was the case how did we make it back on another airline? The weather in NY was cloudy but not bad.

I like for how they process during check in. It was very smoothly.

After I checked in, I realized we had no seat assignment. It said they would be assigned at the gate. This was really frustrating because I usually use a lounge before flights, but I couldn't because I had to be at the gate to ensure we got our seat assignments. The gate agent arrived an hour before the flight left. I was the first one up to ask about seat assignments. She told us to wait for names to be called. Dozens of other passengers were paged, but we were not. Finally, I asked my husband to ask. He went up and was also told to wait. About 10 minutes later, they called for boarding. We still had not been told our seats. We went back to the desk and they were in a panic, saying we actually weren't on that flight. Then they made an announcement telling the stand by passengers to not board (in case we needed their seats). It was so stressful and unprofessional. Finally they gave us our seats. I have no idea what happened and why the two desk agents seemed to have conflicting ideas about our seats, whether we were on that flight etc.

All of the United employees I interacted with were professional and courteous. The aircraft was clean, the food on the flight was good. No complaints here.

There was no food available for this red eye... one little waffle cookie for a 6+ hour flight... thank God I was able to sleep some

Had to cancel first flight because Airporter Bus took over 3 hrs to get to airport which resulted in an extra $378 dollar fare . Is there anyway I can be reimbursed for initial fare since it was not my fault? Sent from my iPhone EJ Ledet

Terrible. Delayed 7 hours, and cancelled the flight, leaving me stranded and out of pocket $500 for an alternative last minute flight

Not a great experience. We paid for the upgrade for premium economy seats and seated ourselves in very comfortable seats. Someone came along with the same seat on their boarding pass. The aircraft had been changed and as a result we were booted out and sent further back to small uncomfortable seats. After complaining we were moved to emergency row seats, which gave us more leg room but the seats don’t recline. For people in our 70’s we found having to sit upright from California to NJ very uncomfortable. Not sure why they chose to move senior citizens instead of the two people that were allowed to take the more comfortable seats. Not happy.

Cramped seat even in economy plus seat 10A. Over booked flight, no space for the bags

Very comfortable (upgraded to business class). The audio on my screen didn’t work, but I managed to play the audio through my phone while watching the screen.

get E+, a must for 5 hours flight if you are tall

Multiple delays and not straight answer from the United team

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

Dreadful experience. Our flight was delayed more than 8 hours due to a maintenance issue and the assistance from rebooking was poor. I was travelling with a bad knee and needed assistance waited in one place more than 3 hours before someone came with a wheelchair. The woman next to me was a 91 year old great grandmother who had waited more than 4 hours. There were moments of support from the staff but it appeared as they were going against the direction of management. It was apathy, lack of ownership and dismissive responses with small moments of kindness and understanding typically from grey haired, female, veteran staff..

Flight was cancelled 3 hrs AFTER etd. Thetefore Missed connection from JFK to New Zealand . No accommodation provided… This cost ne aporox 1000 USD in extra expenses and turned whst should have been a 24 hr trip ftom Boston - New Zealand into a VERY expensive , late 70+ hr nightmare … Complete nonsense!!!

Overall fine, but the delay was annoying and the reasons for the delay were not communicated. The crew on board were phenomenal!

A cookie and a soda, packed like sardines, will never be a positive experience. Also, boarded a 5:30 flight at 7:45pm

Whenever a passenger purchase a ticket his advantage number should automatically to his information. It's not everyone remember the number. You request for your number and American airline agent say they will email it....and they never email anything and you loose your mileage just because you don't remember your number. It should automatically go your information and associate with your email account at all times

Boarding took forever, the plane was cramped and cold, and the seatbelt song came on constantly throughout the red eye flight with a loud pre-recorded message playing each time

Cabin felt crammed Snacks are lame But crew was super efficient getting us out on time despite delay

Everything was great except it became so hot on the plane I couldn’t sleep on my red eye flight. It didn’t really cool down till we started descending.

Flight was empty so had a whole row to myself. Still had to wait to get the bag due to the negligence at Palm Springs departure.

The only thing is if Wi-Fi is available after you land and taxi to the gate. It takes forever to get to the gate, and having the Wi-Fi continue would be great to bide the time at least 5 minutes before you arrive at the entrance. That is my only comment; otherwise, everything was good.

Great for the price. No wifi or entertainment, but gate agents and crew were fantastic and we boarded quickly and left on time.

sluggish boarding and arrival procedures, fake nice flight attendants, and lots of delays.

Disaster. They lied every step of the way. We ended up being delayed due to crew and then allegedly abandoned the flight because of a curfew at LGA. No rebooking to LGA at any reasonable time. No hotel. No meal vouchers. Had to sleep in the airport and fly to Newark instead. Will never fly Frontier again.

What I expected, nickeled and dined and a frontier flight attendant loudly complained about her job and lack of communication as she headed to the gate on her cell phone. Not professional.

As every law enforcement agency I could imagine surrounded the plane and we didn’t disembark for 2 hours and then had to stick around for another hour to go get our personal belongings after leaving them behind and being bused away from the plane, it was scary and inconvenient. We were given no information as to why this was happening. Lack of communication with passengers was disappointing.

After boarding and un-boarding twice over 6+hours, the flight was canceled.

Severe turbulence. Captain never came on to reassure passengers after things settled down.

My first flight was delayed 5 hours. The 2nd flight was canceled til the next day and the never even tried to compensate for it. Worse I was delayed again on the flight the rebooked me on.

Boarding in Orlando was not good. Giant mob at the gate, should have been lines.

Decent clean onboard experience. Okay discount airline experience. Unfortunately, any customer service interactions are difficult and unhelpful. There is no service. Also, a premium seat only gets you premium boarding if you line up first. Once they start general boarding you must go to the back of the line. Not very premium
