I’ve always loved Southwest. No issues at all. I was flying standby and the gate agent was extremely friendly and helpful. Boarding was smooth and I was able to get a window seat in the emergency exit row. Crew was fantastic! They were very professional and accommodating. We had to divert from our destination due to weather but the flight crew kept everyone at ease and informed us of all pertinent information. Excellent flight

Plz don't take away free bags and free seating

My flight to Chicago left and landed early. My return flight left two minutes late and arrived 2 minutes late. My seat selections were ideal! There were no snacks going to Chicago and no snacks on the return trip. There are no charging outlets on board.

Plane late from DC to Austin 30 minutes. Crew made up much of the time enroute to San Diego.

Gate agents were informative and friendly… flight attendants were as well. Had a fun time chatting about their legacy AirTran experiences as a former fan of the airline that Southwest acquired.

Fine, but how to board on SW versus othrr airlines, is just lame. Goood staff though and all was solid otherwise.

The last 30 min or so, they put the heat on full. We thought we were being basted.

The fluidity of the entire process of boarding the plane the flight attendants attentiveness. The flight attendants also provided coloring books for my kids who loved it.

The plane wasn’t full, so we got the best seats
