Paid for premium extra leg room but the bin space for rows 1-3 had to go in rows 4-6 and 4-6 had to go to 7-9 because flight attendants have snacks and their luggage upfront. So we pay extra to have to fight thru traffic to get our bags. Only 2nd day of new seating so hope they fix this.

Delayed flight. Nicest crew member was a SW pilot flying seated next to me who kindly move to seat the final passenger. Flight extra delayed. My cup of refreshment of ginger ale was so packed with ice it was literally 2 sips.

Southwest is Southwest. No frills. If you're luck enough to get a happy crew (we did), then it makes for a nicer flight.

I would have liked to arrive on time - not 5 hours late!

Board Milian spokesman with pre boarding , not after A group and without my spouse. Total BS, back to Alaska Airlibes I GO. oner 1.2M miles and 900 flights, and every time I fly SWA I regret it, thos will be last time, I only flew SWA but to time requirements fir a Funeral. NEVER AGAIN SWA

Good crew, funny movies, but you need phone ports in the plane and better snacks. :)

Had a long layover in rainy Chicago. The staff were attentive - my husband needed a wheelchair due to a recent fall and unsteady on his feet. They are wonderful for those of us who need a bit of extra care. My only complaint was discovered upon unpacking our suitcases at home. One (we had 3 carry on size and one just a bit larger) had water damage to everything inside. All the clothing (just happened to be the case with the clean clothes) were wet. I know it was raining, but why would items inside be wet? The paperwork packed in this case was damp with ink running. There were momentos from our 10-day European vacation that I was hoping to scrapbook - but alas, they will be scrapped - too damaged to keep. The boxes of French chocolate were damp on the outside. My expensive camera now has a cracked screen and a Gaudi tea-for-one was cracked - even though it was packed in clothing. I know it happened on this flight as I repacked all four suitcases before leaving New York in the morning. My first unhappy experience with luggage at Southwest.

4 hour delay and STILL sitting ON PLANE AT GATE. We were told 25 minutes ago it without be 2 minutes. Let me say that again.. 25 minutes AFTER they said 2 minutes. Well, at least we get free WiFi. Oh, wait.

A bit bumpy, but otherwise uneventful, and made up some delay in flight

The a/c wasn’t working very well and it was a very hot flight

Although there were two delays, they were communicated clearly and the boarding process was expedited. The crew was pleasant and efficient.

Plane was super cold. No entertainment unless you were with mileage program Getting off the plane was super slow

Beverage service was not good. Also just one service in 5 hr 30 min flight. No ask fir water ir anything beside one time beverage service.

Flight was delayed because of a bird strike. They had another plane available within 45 minutes.

It was a code share with Alaska - would have been great if I actually made it on the plane, claimed I didn’t have a ticket or a seat even thought I was checked in.

The main problem was delay. The plane was at the gate early and bags were loaded. However, there was no crew for the flight. They were inbound from LGA and had to land and make their way to our gate. It took more than 40 minutes. Then, once the crew arrived and boarded, one of the crew members had to deplane and then a replacement crew member had to be found. It took another 40 minutes or so to get the final crew member. In all, we took off about 2 hours later than our scheduled departure time. Once in the air, the flight was great. Smooth most of the way. The crew was professional and efficient.

i suspect i caught flu on this flight as i could hear someone coughing a few rows back and ended up with flu a few days later. also tiresome to have to watch movies on my device by holding up smartphone screen, would have liked to have in seat display.

I had trouble finding a boarding pass because I had an hour between Flights and American did not see my flight I believe because I was ticketed through KAYAK. I did not have enough time to go to the desk before boarding so I went to the desk and told them while I was boarding and they had a boarding pass for me within three minutes. Nice. I paid extra to have more legroom and it is definitely worth it for a six hour flight. I would’ve paid for a decent dinner, but they didn’t offer anything but a snack box —not good for six hours.

Terrible flight seats where really uncomfortable I had body aches for 2 days and flight was delays almost two hours

Very smooth for one of the busiest travel days of the year and the crew was great.
