The first time I flew in the extra legroom section. It was difficult to notice a difference. I had bad luck with my neighbors. The crew was okay. Southwest has reduced the live TV options.

The first time I flew in the extra legroom section. It was difficult to notice a difference. I had bad luck with my neighbors. The crew was okay. Southwest has reduced the live TV options.

3 hour delay. Had to change plans and was still delayed.

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

Delays delays delays. Late taking off, late landing, wait for a gate, etc.

First time traveling on Southwest since bag fees were implemented. Usual good service. Just more expensive now.

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

Flight was delayed more than 2 hour do the scheduling issues and then some confusing weight and balance matters, followed by a miscommunication with the tower on which runway was going to be used based on the airplane weight. All these things should have been figured out in advance. Instead of arriving at 12:30 a.m. we arrived at 2:30 a.m. very difficult to find a taxi or other transport at SFO. Luggage was delayed. An extension of an unpleasant flight day

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.

Everything was great except for the in-flight wifi that wasn't working.

no entertainment options available on a 4+ hour flight. packed in like sardines. one bathroom. late flight.
