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

Good but I prefer choose your own seat. With the new assigned seats they should board from the back I see no advantage to this new boarding. Just like every other airline

Snacks are always pretzels. Why can't you also offer peanuts ?

Only downside was the legroom and seat width, which is always a problem unless I spend more for a premium seat.

Very good. Sad to learn Southwest is going start to charge for bags

Forget beverage, they didn't even have water for half the passangers?

Crew was excellent - Plane was fine. Media was good, could use more kid shows; Not a fan of the brownie brittle -- snack could be slightly better.

Nice and easy. You can't go wrong with the value and quality or Southwest.

I loved that the flight was not as full, so we were able to have seats available between us. I just wish wipes are available as we board so that we can clean our areas, as the window area was quite dirty in my case, on both legs of this trip, and it was hard getting the flight attendant's attention for this. She also seemed a bit stingy with the free drinks. I asked for two cups of drinks; she brought one and then waited until I fell asleep and brought the other. Not sure why...

Internet only worked half the trip Drink was flat Staff was great
