It was good. Last flight was delayed but I always say that is in God's plan

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!

Plane was late. Zero service for 2+ hour flight and it was not that bumpy.

The staff was very friendly, professional, and courteous. The overall flight was a great experience.

southwest just starting charging for luggage. hadnt realized it until it was too late. now out $70 when i couldve bought a carry on if i wouldve known. free bags was one of the only reasons i chose southwest over another airline (the other being no assigned seats, which is apparently also being changed). stupid business decision. wont be flying southwest anymore.

Cluster mess boarding. Can't wait for SWA reserved seating. Internet didn't seem to work on the plane.

The price of the tickets isn't matching the flight experience. No matter how long the flight is, you're only getting pretzels. The flight attendants looked unkept and over it.

I liked the boarding by group and numbers. I didn't like my inability to guarantee our seats together. I didn't like the $8/flight for Internet, but I did appreciate the inflight movie options on their app. I didn't like that there were no charging stations on the seats during either of our flights. One flight was over 3 hours.

I never like the fact that if I don't check in exactly 24 hours before the flight time, I get to board C, and that means sitting between 2 individuals. I would like assigned seating in the airplanes.

Flight only half full. Room to spread out. Newer plane. Very satisfied.
