It was very good and comfortable, Crew was also great

Good experience, although it was a little cramped being a tall person. Otherwise everything went smoothly and professionally though

Delay of more than 3 hours I didnt recieve neither a voucher for food Attention disaster

I'm a platinum member with American Airlines, however, my ticket did not display status and thus I did not board with an early group. I traveled with my two daughters and we were given a row of seats that did not recline. Not the treatment I would have expected for a platinum customer. The flight was also a bit late leaving Portland. Also on my flight to Portland we were not given premium seats. In fact, we were in the last row of the aircraft.

The seats in first class are very dated and quite uncomfortable. I don’t need lie-flat seats for a 6 hour flight, but more recline is really necessary.

One of the stewardess, Tre, went above and beyond to ensure my comfort!

Alaska app and website had numerous problems so couldn’t get boarding passes or check seats

Flight was very warm. It felt like there was no working AC.

Big delay of over 7 hours on next leg of trip with Alaska. Would have been nice to have food or something

Very good. Gate personnel were excellent flight attendants were also able to change my seat at the last minute everyone, courteous, polite, and.

First time traveling on Southwest since bag fees were implemented. Usual good service. Just more expensive now.

It was a perfect flight in all aspects! Both legs!

Boarding process, crew were good. But the seats were so uncomfortable that was all I could focus on. I literally had to sit forward so that all 3 of us could fit in row. I will try to avoid Southwest in the future for any flights over 60 minutes.

Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.

Great experience flying Southwest. The crew was really kind and helpful, and very friendly with our toddler.

Plane late from DC to Austin 30 minutes. Crew made up much of the time enroute to San Diego.

Fine, but how to board on SW versus othrr airlines, is just lame. Goood staff though and all was solid otherwise.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a not a great airport.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a hell hole of an airport. It is the new LaGuardia. Everything Cobbled together. Security gates closed. Terri directional signage

I will be flying again Southwest Airlines. Friendly crew, comfortable and affordable.
