Had a great flight. Delayed takeoff, but comfortable. Snacks were good.

Pretty seamless, just a tad bit late in taking off and landing.

after landing, we stay 2 hours on the taxi way before reaching the gate The airline and the crew were good though

My flight to Chicago left and landed early. My return flight left two minutes late and arrived 2 minutes late. My seat selections were ideal! There were no snacks going to Chicago and no snacks on the return trip. There are no charging outlets on board.

Gate agents were informative and friendly… flight attendants were as well. Had a fun time chatting about their legacy AirTran experiences as a former fan of the airline that Southwest acquired.

The fluidity of the entire process of boarding the plane the flight attendants attentiveness. The flight attendants also provided coloring books for my kids who loved it.

It good. Just not that plane didn’t have power outlets to charge devices etc.

We stood on the tarmac for over an hour. Very bad turbulence the whole ride. Very to get to the restroom.

C Am handicapped and couldn't get help with my luggage.

Healthier snack would be much appreciated. Love traveling on Southwest!
