The flight was late. The crew was rude. There was no food. Cramped and uncomfortable. Nothing about this flight was good.

Crew was rude, flight was late, wifi didn't work, no food, basically nothing about this flight was good.

It was just okay, no frills, basic transportation with no luxury. No screens on the seats, no water or drinks on a short flight. Full flight but at least it was on time.

Flight was constantly delayed with significant changes in time, it was supposed to get to Colorado Springs at 8:30 PM but it got there after midnight.

Over a 3 hour flight. The turbulence was almost imperceptible except for 2 short periods which were not bad and over quickly. The attendants claimed "Safety first" and sat looking at their phones for 3 hours with no drink or snack service. This isn't the first time with Southwest. I thinkit may be there new plan of operation. Oh, and it was June 18, Southwest's Birthday which offered free drinks. NOT.

Flight was delayed, full flight and I had to change gates. Southwest flights are always late later in the day.

Flight was delayed over 3 hours. Planes were dirty. Staff indifferent. And they serve vegan pretzels as snacks.

It was great. The gate staff were very helpful in Portland when my son forgot his rolling bag and had to go back to get it just in time to make it on the plane. We really appreciate that. Great job!

Airline is not very senior friendly. Flights are late, forcing us to run to the connecting flight. Food is awful. Wish they would go back to pretzels and peanuts. During flight, pressurization isn’t quite right and all of our ears get plugged. Everything is nickel and dime, charging for boarding, seat selection and legroom. While a screen at the desk in the gate area says check your roll on bag now for free due to space limitation, the employee at the desk will not check the bag without a $100 fee. Insane.

Kayak could’ve posted the correct gate number. Almost missed my flight.
