I have not flown Southwest in awhile and had a very pleasant experience. From ticketing to boarding to the flight. The flight left on time and landed ahead of schedule. It won't be so long next time!!

The Southwest experience has definitely taken a dive from its early days. You can no longer deferentiate from other airlines. Air travel is too expensive. Southwest is no longer budget friendly. They have lost me as a loyal customer.

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.

An entire day of delays. Cost lots of money. Meals and a hotel.

Great plane, great attendants,great flight crew,on time. Wonderful flight home..

The WiFi and crew on the plane were good, however, the boarding experience was awful. I paid for the Choice Preferred and was boarded in group 5 so all overhead storage was full. They found room for our luggage, but further back making getting off the plane a nightmare. Also, we were in row 6 and the seats were extremely uncomfortable. Both my daughter and I had no leg room and couldn’t wait to get off the plane.

The charges were ridiculous for an hour flight and the turbulence was very scary.

Still need to work out the kinks on the new assigned seating boarding process. Otherwise, a very good flight.

WiFi did not work. Boarding with the new seating assignments took too long. The temperature in the terminal was obnoxious. +/- 80°
