Over all it was great. My original flight was canceled but they quickly rebooked me. I was frustrated because I had to cancel my entire plans for the day but all considered, not bad. The crew tried to keep us calm while we sat in the plane for was felt was an hour or so but they could use a bit of a script. The seats were comfortable and I would give it another try.

Over all it was great. My original flight was canceled but they quickly rebooked me. I was frustrated because I had to cancel my entire plans for the day but all considered, not bad. The crew tried to keep us calm while we sat in the plane for was felt was an hour or so but they could use a bit of a script. The seats were comfortable and I would give it another try.

Having the internet available while flying was great. Better than having to choose from watching movies from a limited selection.

Not able to get boarding pass for domestic connection flight when check in at international airport. I was told I need to get connection flight boarding pass after I entered US. It us very inconvenient.

I was very impressed at how Alaska Airlines handles people with medical needs.

Everything went smoothly from the transfer from Orlando to a quick board. Flight was not full and we were able to get underway a little early. My only critique is that in Orlando, they offered active duty service members and veterans to board ahead of their zones in the initial boarding process. They did not offer to veterans in San Diego. Both flights were comfortable

Good flight overall. Lots of bumps during flight but pilot kept searching for smooth air

The gate agents begged us to check our carryons. They BEGGED us, over and over, and said that the flight was completely, totally full, and said that if we don't check our bags, it will cause huge delays. They finally said that "group suchandsuch will be required to check bags!" So I checked mine. Well, the flight wasn't close to being full, and many of the overhead compartments were *empty*! Moreover, my bag was delayed at the carousel, and it wasn't on the carousel that was posted. COME ON, AIRLINE, you can look at the seating for the flight on your computer and decide whether it's really necessary to beg and beg and beg people to go through the hassle of checking their bags! This is annoying as hell and makes me not want to use your crummy airline ever again.

A gluten free option I could actually eat would have been nice.

Good. I didn’t order food and there was no entertainment available.

It is a hassle to not have entertainment screens on the backs of the seats.

The first time I flew in the extra legroom section. It was difficult to notice a difference. I had bad luck with my neighbors. The crew was okay. Southwest has reduced the live TV options.

No gluten free snacks. Seats felt worn or bare bones even though it was a new 737 MAX 8.

Plane was clean and comfortable. Flight attendants and gate staff were professional, friendly and efficient. Boarding and deplaning were orderly and efficient. All in all, the typical excellent Southwest experience.

Not having a five hour delay with little notice! The crew was very kind, though, and just as tired as we passengers were. The flight didn't depart until nearly 1 am...and no reason was ever given.

This leg was much better, but we did have to have a 3 hour lay o er after coming from a very exhausting hiccup with our flight from BNA to Den

The Air hostess were very rude on my flight from Houston to Austin . Their regular communication itself felt a they are shouting at people.

Boarding was easy. The seats are small and fairly uncomfortable

The problem with the seat assignments is that there were a lot of rows in the front that were empty but my row at the back was full. Just not so pleasant.

No food or entertainment, just a quick 40 minute flight. A little bumpy due to Santa Ana winds but pilot has no control over that. Good flight and landing!

Good but I prefer choose your own seat. With the new assigned seats they should board from the back I see no advantage to this new boarding. Just like every other airline
