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

Flight coming out of Buffalo was delayed, so we had to be rescheduled on another flight from Baltimore to Phoenix which means we had a long layover and got home 3.5 hours late. Shuttle to parking stopped at 10pm, so we had to pay for an Uber to the parking lot and got charged an extra day of parking since it was after midnight. Not the best experience. Long day!

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

Airline travel is always too cramped to really be pleasant, but the cabin crew on this flight did a pretty good job of making up for it by putting on some music during boarding and sprinkling a few funny remarks into the safety briefing and announcements, and just generally being friendly and helpful. It definitely reminded me of why I prefer the in-flight experience on Southwest!

It seems as though the provisions are even less. Although SWA used to be an economy Airline, that isn't really the case anymore. I paid over $700. for a round trip to Denver and I could have flown just about any airline for the price. The drinks are now in a 6-ounce cup and with ice I'm sure a can would fill more than 2 cups. However, I am very proud of SWA for using paper rather than continuing to contribute to the millions of plastic cups being used each day. I've thought of this fr many years and am so glad to see it come to fruition, if not by only SWA so far.

Crew was great - friendly and helpful with boarding - letting folks know where overhead space was available thus getting us out of the gate on time.

AC wasn't working then we sat on the tarmac in Austin for 40 minutes waiting for a gate.

I stopped flying southwest a long time ago. I don’t care for their boarding process, especially when I have a family to try and seat together. The early bird check in made it so much easier. As long as you do that, it’s great.

Excellent! Very attentive & helpful during a weather delay to keep people safe, com, and informed!

Issue during taxi lead to two hours of sitting in the tarmac and a lot of miscommunication and confusion from flight crew

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!

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

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.

They were an hour late and they didn’t have my wheelchair for me

Food service was bare-bone. Better bot to have any at all rather than hand out premade coffees and cookies to random few passengers.

due to delay, we were downgraded in seating, so it was cramped

Crew handling the boarding at the gates are quite aggressive with the passengers and must be given training/ refreshing courses to improve customer experience.

On time departure & early arrival. Made a long day much better.

Leave on time. We waited on the plane for hour hours and it was hot and smelly

It was the most un-special flight experience in my life.

Massimo, flight attendant was very authentic, attentive - wonderful. Food/wrap was just okay.

2 hour delay due to equipment failure. No updates via the app and airport screens (which continued to show a departure time in the past). AA eventually switched planes and the new plane was not catered or cleaned correctly.

The plane was very warm and the crew turned on the lights for the entire snack service.

It is okay. Flight was on time to start and early to land

The gate crew did try to help, however they lacked the information as to whether the flight will operate or not. Being delayed 6 hours and in a limbo on whether the flight will operate or not is not fun. The airline having staffing issues is not encouraging at all.

Gossipy flight attendants talked the whole flight about bar hopping and dating.

Best price with timings that suited us. The flight was punctual.

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….

An absolutely fraudulent experience. Extremely unprofessional. Terrible in all ways possible. Rude staff, flight attendants, and deceptive "policies."

Be prepared for crowds and chaos upon arrival at the Orlando airport
