Long layover in Chicago. Wish that could have been lessened.

Worse experience especially since there were delays and unreasonable accommodations made

Long delay due to mechanical issues. They should have just swapped the plane and not make us wait while they figure it out. Disappointed

sw cancelled our flight 2 hours before we were to leave. Our bags were already checked. Only communication we had was a text that had a link to reschedule that did not work. When we finally got to front of line ticket agent said they could not get us on a flight until Wednesday. This was Sunday. 3 days. The. They stated since it was “weather” related they would not give us vouchers for food, hotel stay anything. So we had to book on a different airline costing us an extra $1000. Unacceptable.

Two hour delay including one of them on the tarmac second year in a row we’ve had a bad experience. Sad that Southwest is no longer a bargain and has failed to keep up the customer service they were once so famous for.

Everything went smoothly and the plane wasn’t full. It was delayed though. .

Really full flight, checked in ASAP and still mid Cs.

Appreciate that when flight was delayed, our next connection waited for us.

no entertainment options available on a 4+ hour flight. packed in like sardines. one bathroom. late flight.

Southwest is definitely the happiest airline to fly with. They are always kind and friendly with a sense of humor.
