Poor customer service, no accommodation for passengers when the flight was delayed over 5 hours.

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!

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 charges were ridiculous for an hour flight and the turbulence was very scary.

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!

The plane arrived 25 minutes late, and the Wi-Fi was slower than it usually is.

Flight was on time and the crew was very nice.

Flight was delayed for 1 hour. Otherwise it was a fairly normal Southwest experience

Main flight attendant made light of the delay and presented some humor to lighten the tempestuous situation. Delayed flight took off 2 hours after scheduled time.
