I've taken four flights with Southwest within the last three months and every single flight was delayed.

I've taken four flights with Southwest within the last three months and every single flight was delayed.

I liked the new boarding process. I thought the buyup options (legroom, early boarding) to be easy to request and reasonably priced. All the Southwest team from gate to in-flight were so nice.

Flight coming out of Buffalo was delayed, so we had to be rescheduled on another flight from Baltimore to Phoenix which means we had a long layover and got home 3.5 hours late. Shuttle to parking stopped at 10pm, so we had to pay for an Uber to the parking lot and got charged an extra day of parking since it was after midnight. Not the best experience. Long day!

We had a 5 hour delay on the tarmac in Baltimore

Airline travel is always too cramped to really be pleasant, but the cabin crew on this flight did a pretty good job of making up for it by putting on some music during boarding and sprinkling a few funny remarks into the safety briefing and announcements, and just generally being friendly and helpful. It definitely reminded me of why I prefer the in-flight experience on Southwest!

Flight was delayed due to plane not passing inspection And one of the crew had to time out and we had to wait for another one A 3 hour delay

It was one and half hour late... Not sure if any other experience matters.

It was 2 hours 45 minutes late, for no apparently clear reason.

It went well. Plane wasn't full. Will be great when assigned seating is in place

My bag was damaged and is now missing a wheel. I tried to buy a claim in on the website but it would not accept my confirmation # for submission. Other than that, everything else was good!
