Crew was a little surly. But plane left on time and arrived early. All one can ask for. New 737 Max was nice.

Crew was a little surly. But plane left on time and arrived early. All one can ask for. New 737 Max was nice.

Had to walk back and forth between concourses to figure out which gate I was supposed to be at. The app and the flight board in the airport had different gates listed. Was told numerous times to check bags only to get on the plane and find that there was plenty of room for bags. The flight was over an hour late which had me landing after the last train departed. WiFi was unusable

My experience was okay I changed my returning flight and I was charged extra money which I dont think should be the case, especially because I experienced small delays from my going flight. And many flights were either canceled or delayed after my original flight time. I believe some customers should have the ability to change flights due to certain situations

WiFi was inoperable - second in four recent Southwest flights where that was true. I need WiFi for work and if Southwest cannot provide, I’ll stop using it

Your computers were down and took a long time to check baggage

Flight attendant skipped about 6 rows for drink service. I got a side eye when I asked for a drink - like it was an inconvenience or my mistake. He shouldn't be on a flight if he doesn't like his job and doesn't have customer service first attitude.

They did not fix the wifi that they knew was an issue on an earlier flight. The flight was filled with business people that were clearly frustrated not being able to work. That can’t happen on a 3 1/2 hour flight. Would rather have been delayed a bit.

Eveeyrime I fly they are begging for bags due to cabin overhead space. What they should so ia take the bags that are clearly too big to fit wheels first on their side. And those of us who give up the bag should really get their bags first. When boarding, nobody wants stupid jokes about how hot it is on board. Give us some cool air. Im usually sick from the heat by the time we take off.

My experience will Southwest was good. I wish there was more entertainment and the boarding process was slow at time but other than that my experience was great definitely will be flying with SouthWest again.

if I was good. Not happy that I have to pay extra money to get the seat I need for lake room, but I guess that’s a sign of the times.
