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

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

SW can't get their wifi right. I upgrade to insure wifi service but the last two trips had intermittent service. Not worth the extra costs.

One major problem that was very unprofessional and uncalled for. Plane landed and we had to wait 20 minutes to get off the plane since they were waiting for someone to come to the gate to drive the jetway. Southwest couldn't have someone available and waiting for the plane to land? Is there only one person in Hobby airport who knows to drive the jetway? Was he at lunch? In the bar? Uncomfortable and uncalled for!

Southwest is kind of a slum airline. It’s gotten more expensive over the years for less and less service. I am a Southwest Chase Visa card holder and was forced to choose a seat in the 26th row in the middle seat. However my wife who is a rewards member but doesn’t hold a card or anything else, gets randomly assigned a normally paid seat in row 6! How does that work?

The seat was not comfortable. 1D. My back was sore all night and the next day.

One of the best airlines for fast boarding, on time arrivals, and top notch service!

I elected to pay for the upgrades and found very little difference

The new seating arrangement is so over priced for what you get.

Flight was hours late, unable to sit next to spouse, I have had so much better experiences. Substantially better, only saving grace was that it was a short flight.

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

Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

Smaller plane for a longer flight than my first one. Doesn’t make sense.

Another late night flight and MORE men belligerently drinking and yelling. I had to move from first to economy because they were so obnoxious and disruptive. Crazy to go from a cozy chair to cardboard when you were supposed to be in first. Delta allows was too much drinking which leads to belligerent behavior.

Delta flights recently are always delayed AND at jfk tney get the gates further away (need To walk 20’ to get to them/all the way at the end of the terminal). Not sure whats happening but price doesnt match experience!

Only freetext wifi was available in flight; browsing WiFi required payment. Since the seats had no in flight entertainment, Delta should revisit this policy on this longer flight.

Because I was moved to an exit row, the snacks in economy comfort, the selection of snacks was better.

The entertainment screens were not working and there was no air condition the entire flight. Very uncomfortable.

Lounge in Lagos is terrible, food on board from Lagos to Atlanta was horrible. Only bright spot the cabin crew were awesome.

The flight was scheduled for 2:30 PM. Early in the morning we got a text message saying the flight was delayed and rescheduled for 3:00 PM. We got to the airport with that in mind. Then we got a message during check-in at the flight was rescheduled again for 2:30 PM. We almost missed our flight. In fact, our bags Were told that they would not make it. At the end, everything worked out. But it is very stressful.

Our flight was delayed in Atlanta. The staff could have gave us an explanation for the delay and how long it would be.

Flight was 2.5 late. Maybe not United’s fault but late none the less. We were late as well on the first leg. WiFi quit working with an hour left.

Very stressful to locate United Airline boarding area, delayed flight, changing boarding area again to another location with all tiredness 😩. But flying was fine.

Flight staff and all was fine. Food always sucks on planes so nothing new.

Wonderful flight! The crew was good, check-in was good and orderly and the flight was uneventful and good.

The international portion was good. Food and beverage options were good. The sustainable wooden eatery was less than desirable. Your Star Alliance partner ANA provided real silverware. I'm 6'3" & 198 lbs and felt cramped in the exit row. How can that be? Flight attendant all had a pleasant disposition which is always good.

The staff were polite and professional. I found the boarding for First Class Business customers not great. They didn't offer me pre- boarding. Just regular zone 1 boarding which didn't feel great. On board and throughout all of our United Flights we found the staff wonderful. We'll definitely fly United again.

Boarded from a very small gate at LAX. Staff at gate had us line up, then waited 25 minutes to board without a word of explanation. Plane arrived on time then waited 20 minutes for a plane to vacate our gate. Majority of bags arrived after 15 minutes but it took an hour for a small number of remaining bags to be off-loaded despite my “priority” bag tag.

No access to the Wi-Fi, noisy group of people made it difficult for me to hear through my earbuds. Snacks and drinks - limited service when your seat is at the back of the plane - people up front are always served first and the back gets whatever is left. Not pleased.

Didn't make it dir to delays - no support from United staff

My seat was broken. WiFi didn’t work. Gate crew at HOU were rude and condescending. Treated all the passengers badly. Bad experience, United.

Smooth flight, on time, got to DFW early, crew was great, I was on row 11 so lots of room. Snacks were OK. We were pleased.

Flying on this airline is nothing short of a full blown circus clown show. It is so mismanaged it should not be in business as there is no way it can be safe as badly as it is managed. It is 100% about money and customers be damned. On a recent return from my mother’s funeral, my only available choice from IND to PWM was American, which I hesitantly booked as I rarely fly them for many of the following reasons and never will again. I was booked IND-PHL-PWM totaling about six hours. The flight was cancelled due to NE weather. They rebooked me on a two stop flight IND-DFW (Yes DALLAS)-PHL-PWM, still all on the same day. After arriving in DFW, they continually delayed the DFW-PHL flight due to maintenance issues on the arriving flight. Finally it was delayed to the point that my PHL-PWM connection was no longer possible. They then rebooked me thru LGA with the short flight the NEXT DAY to PWM and offered to put me up for the night in NYC (or so I assumed). The flight DFW-LGA was then delayed so much that I asked to be put in an earlier flight with a lessor delay. Throughout this day chats with their AI assistant were useless as were subsequent chats supposedly with a real person(?). Only one customer service agent in DFW was actually helpful and appeared to care. Upon arrival at LGA post midnight, they issued me car and hotel vouchers in Trenton NEW JERSEY at a very old Howard Johnsons ONE HALF HOUR from LGA. The hotel was an $85, 1.5 rated hotel in a very sketchy area of NJ that I would have never voluntarily booked. As I prepared to catch the car back to LGA the next morning I received a text that my flight was cancelled. TWICE IN TWO DAYS. I went to LGA hoping to have AA book me on an earlier Delta flight. The full service line was at least 200 people deep, so I tried to reach a real person agent by phone. After 1/2 hours on hold I gave up and waited for my later LGA-PWM flight. It actually started boarding on-time, but only shortly after announced a maintenance hold. We were told it was nothing serious, just an adjustment to the Captains seat. Only one update was given while we waited 1.5+ hours for a “SEAT ADJUSTMENT”. During that time at least three others flights in my area announced that they were overbooked and were taking volunteers before bumping people. Another flight to ORD announced a gate change and less than five minutes after announced that they were really not changing and announced for everyone to return to that gate. Can’t forget to mention that on all of these planes the WiFi only worked on two.🤡🤡

The seats we paid a lot extra for so we could sit together were horrible. The flight attendant even mentioned this to my wife after she was hit multiple times by the cart. She said something like this, “this is the worst seat on the plane and I know you paid extra for it. Sorry.” The entertainment screen needed to be held while using, the food tray was not useful for the meals they served, and constantly being bumped into by passengers and crew. I offered to switch with my wife multiple times, but since I am so much taller, my knee would have been a much easier target.

American notified via app that the flight was delayed. However, when I went to the gate, they were already boarding and had not updated communications that they had pulled the flight time back. They made the entire flight re-check in which by this time I had lost my exit row seat and ended up in a middle seat. As a 4 decade flyer of American and Exec Plat, my expectations for the company are that the customer service would be better. This unfortunately is no longer a strong point for any of the major airlines including American. They are basically city buses flying at 30 thousand feet.

The power outlets were not working for my row. Also felt like the seats have gotten smaller. I was in the window seat and felt like suffocated, as the two passengers next to me were tall and wide.

No AC, no beverage service and no explanation from the captain. 4 flight legs in 2 days with no internet service.

The gate experience at LAX was abysmal (same for the arrival experience two days prior). Despite the LAX -> SAT schedule of two flights daily, our departure gate was at a smaller hub that we had to be bussed to from Terminal 4. Fortunately, I arrived at LAX extra early and had time to spare, but if I had not known, I might have missed my flight. I looked at the LAX airport map in the AA app and there was no indication of the additional boarding process. Lastly the gate area we were bussed to was crowded with limited food and beverage options. On flight, the fight attendant was hospitable and attentive, the flight was smooth, and AA's free (and working) wifi for AA members were all on the positive side.

Got home at 3am after deboarding the plane. No compensation offered by American

AA was a very good experience. The employees are wonderful

Awkward carry on process. Forced to check all carry on. No overhead space of worthiness. Left delayed, but made up the time. Crew was amicable.

Terrible. Delayed my family flight for several hours affecting family plans

Flight was delayed and then my second leg was completely canceled. Had to get a refund

When I wanted to check in 3 hours prior to boarding time, the employees mentioned “a little over an hour delay” so I waited for an hour then I went to go look for food in the terminal and most people from that flight were in the same area looking for food. Finally I decided after food to check to see if it’s anytime closer and now it’s 2 mins until boarding closes?! What are you kidding me? I didn’t receive anything via sms about boarding now nor via email or on the intercom. I luckily made it through, barely, and then there’s no room for my carry on mind you I’m in the very first row so I had to place my purse in one further row back and my carry on sections down. Not sure who pays for better seats to get your stuff placed all over the plane but that was the worst experience I’ve ever had flying with anyone.

baggage clamed had to wait over a hour and half for all people on my flight it was terrible

My flight was canceled I was promised a reginf still not received.

The confirmation # CK8GNW and my name was not recognized/in Frontier system. I was able to check in on Frintier app so i went to the Frontier ticket agent, at time they told me that my name/ confirmation did not show up as a purchased ticket. I had to purchase a new ticket that cost $289.00 one way.

Worst airline experience. They were rude and kept changing our seats and/or giving our seats away so our family didn’t get to sit with each other. Almost everyone we dealt with at both airports with this airline was rude. The app kept giving us wrong information making things take longer. Dealing with them before TSA can take close to an hour…longer than I’ve ever had to deal with before. Never using this airline again.

It was a short flight so no food or entertainment….

First time experience and though you'll pay for *everything* meaning bags, water/snacks, even a question with a service agent - - all in all, not a bad experience whatsoever.

I like the easy check-in and boarding process. I love the non stop flight
