Easy flying with Southwest, Hobby (HOU) and San Antonio (SAT) airports are small and easy to navigate.

Friendly crew. Snacks were carb-heavy. Flight was quite delaye

The service was fine, about the same as you get on most lower end airlines. I dont understand the perks of flying them much anymore for the cost.

I've taken four flights with Southwest within the last three months and every single flight was delayed.

Smooth flights, connection, and friendly crew in the air and at the gate.

Overall great! Internet was a little slow but no other issues.

One, we were met with more than six hours of delays with no information flowing from the airline to the passenger. I had to continually refresh for updates to departure time - which changed multiple times throughout the day. Updates were never pushed to me nor was an explanation provided for the delay until this morning. Two, while they claim that "due to the short flight" no beverage service would be provided. Our flight was mostly empty. I'd think given the massive inconvenience, SW could have shared a Diet Coke and some peanuts. And BTW, SW used to always make these available on this flight back in the day. Let's be honest, this is cost savings at the customer's expense.

I like the staff members they were super nice and helpful very sweet people :)

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

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.

Gate agent and flight attendants were efficient, but more stern than warm.

Great quik boarding, friendly gate agent and crew. Let early

The wifi was barely operable. just enough to charge me, not enough to be useful. I wasted 2 hours of time I could have been working. So now, I' have two hours of work this weekend to catch up on thanks to Delta's crappy technology. Plus I'm out the money!

It’s a 3 hour flight with no entertainment and no WiFi due to Delta using old planes on this route and food is cold. Today we were told no potable water on the flight to even make coffee or tea. Ridiculous service in this direct route for business travelers and non business travelers

Audio Visual Equipment lacking content and features. No connection ability for noise cancellation pods

All good except the dining. Both meals were the worst I’ve ever encountered on any previous flight.

Delta is getting worst by the minute. Where this was at one point my only go to airline, it has become like a budget airline

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

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

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

There was no internet on the flight. As an executive flying during prime business hours, having internet is critical for a smooth experience. This impacted productivity and time that will need to be spent later to do the work I could have done on flight.

They took us all the way to Monterrey to tell us they United were not allowed to land and we were sent back to Houston. Terrible experience.

Great flight and crew. Need more legroom and DO NOT allow seats to recline.

I dont like to buy ticket type no carry on because I can have along with me my personal stuff like computer, headphones etc etc

Flight was very smooth from Boston. But when we got to Houston, the gate was not open and we waited on the runway for over 30 min!!

I couldn’t give an honest evaluation, because the Houston airport has a problem and I was stand up for several hours and after a long trip from Munich I feel really very tired

It was very good. the food was varied and tasty, the movie was the same, maybe I would recommend changing the movie selection every month because my flight to Amsterdam was in September and I came back from Munich en October they are flights so long and we need something to see. But however I liked flying with United

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.

The gate agent in BNA got irritated with a lady for asking her about standby's and refused to hand out assigned standby tickets to ANYONE until Group 6 . She punished all standby passengers because of the one lady she did not like. When we boarded she said thank you to everyone as we scanned our boarding passes except the lady in front of me. Very petty and unprofessional

Totally uninformed of the situation. Not yet sure about compensation. Highly disappointed.

Horrible. Their delay cause me to miss my connection, the the flight they rebooked was delayed over an hour because they over booked the crew. They also left my suitcase out in the rain for hours ruining items I had in the suitcase and blew off my complaint.. worst experience ever.

Crew tried to accommodate late arrival due to late departure

AC wasn't working properly and the WiFi was also not working properly for stretches.

The flight from DFW to SAT started out with a 2 hour delay. It was a five hour delay with no real explanation as to why. In addition, the time of arrival kept changing from 10:00 pm to 11:00pm to sometime after midnight. Driver picking me up in SAT was as confused as I was. Flight attendants were patient thank goodness since folks were a bit upset about a 2 hour delay that stretched into 5 hours.

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

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.

Airport staff was terrible, they made up excusses on how I can get to my terminal, I missed my flight then had to pay for A whole other flight! Worst experience ever, even A employee also loughed and said yea sorry for our poor training.

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.

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
