No wifi, seems to be very common with Southwest currently. Everything else was normal.

The Air hostess were very rude on my flight from Houston to Austin . Their regular communication itself felt a they are shouting at people.

The flight crew was extremely rude and especially not helpful when our flight was delayed.

Still a fan of open seating. Flight was on schedule and arrived on time. The 737 MAX is very comfortable.

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

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

Our first flight was so delayed that we had 10 mins to board the next one. We requested if the flight attendant could allow us off there plane first and they denied our request even though I have seen this done before. Luck was on our side that we didn’t miss our next flight.

The flight in it self was good. The delays looking for pilots was unexpected.

This flight left late. We had A46/A47 boarding, but SW boarded 45 people from an interrupted flight ahead of us. It was a zoo. Seats are very uncomfortable, even for a 5’8” person of normal BMI.

The crew was very helpful, nice friendly. The only issue I have was the horrible turbulence that we experienced leaving Dallas love field airport. It lasted about 20 minutes I think.
