2.0 Poor
They sent a notice that they were boarding an hour early. We had to leave the club and run to the gate. They said sorry, that came from corporate and was a mistake. They did not have enough seating because the flight before it had not taken off on time. They moved our gate and delayed it for an hour.

The boarding and seat assignment system no longer works for me, but I know it is being replaced. Otherwise, I am good with the overall experience.

2 hour delay

10.0 Wonderful
The lead steward kept singing about "San Francisco" and hotel California---more annoying than humorous....needs work. Flight was smooth and on time.
A
10.0 Wonderful
Still a fan of open seating. Flight was on schedule and arrived on time. The 737 MAX is very comfortable.
T
2.0 Poor
Multiple delays, canceled flights, and flight reroutes.
D
10.0 Wonderful
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!

Excellent experience, no complaints.
