All was good. I just had a hard time getting connected to the WiFi/internet during the flight

Sacrament staff are always polite and helpful. Airport is easy to maneuver and boarding is straightforward.

Great flight. Outstanding Service. Southwest was able to put us on a direct flight to Denver when the connection could have been affected by a later arrival to Baltimore. The direct flight was less expensive that the flight with the connection in Baltimore.

Delays delays delays. Late taking off, late landing, wait for a gate, etc.

Boarded on time but once we were ready for take off, the crew determined that, although every seat was taken, somehow someone was on the wrong flight. Delay, delay delay, announcements and ended up with one person checking EVERY ID against their passenger Manifest only to figure out it was a "clerical error." We departed 54 minutes late causing me to run in the St. Louis Airport to make my connection and lose the priority boarding spot I had paid for. Unnecessary delay.

I was re-booked onto another flight because my original flight was delayed and I would have missed my connector. I ended up in the “C” group after paying extra to be in the “A “ group on the original flight. At least if you’re going to re-book people, re-book them into the same group.

Flight was delayed due to plane not passing inspection And one of the crew had to time out and we had to wait for another one A 3 hour delay

AC sub par. WiFi not working correctly. Ac sucked. Seats very narrow.

southwest just starting charging for luggage. hadnt realized it until it was too late. now out $70 when i couldve bought a carry on if i wouldve known. free bags was one of the only reasons i chose southwest over another airline (the other being no assigned seats, which is apparently also being changed). stupid business decision. wont be flying southwest anymore.

Flight crew and cabin crew were great. I had to rearrange flights because my original flight was 3hrs delayed for weather, the rub is the flight I moved to boarded on time then we sat at the gate for 2 hours because scheduling stole our first officer for another flight, TWICE. Then our actual FO was an hour delayed. To make it worse my original flight went from a 3 hour delay to departing 15min EARLY. Just poor scheduling operations all around.

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

The newer screen was super cool and had the option to watch many different shows or movies. Crew was polite and helpful. However again, many children screaming bloody murder and kicking my seat, and parents doing nothing about it as usual.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

Plane was crowded and even when we hit altitude, the plane was hot, not enough air flow.

Was on time until within 1 hour of flight-how does that happen? Staff very friendly.

Overall it was good. I missed my connection but I was put on another flight.

Gate agent did not hold flight for connection, provided no assistance to get new flight

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

We boarded but then sat there waiting on some missed connection people to get on so we sat for about 15 minutes for that. Then we sat again because the passenger manifest was wrong and they had to figure it out before we could leave. That took about another 20 minutes or so. The crew was working hard to figure it out so it’s not their fault. It ended up being a system glitch where someone was upgraded to first class while another person was also in the same seat and it just created a mess that took a little while to figure out. They literally went to every person on the plane asking their names to see who was sitting in the wrong seat. I also hate the entertainment that must be watched on your phone or tablet. Just give us setback screens. It’s so much better. Almost every Delta flight has this now and it is so nice to have them. The crew did a great job. I have no complaints from them. They were very hard working, even with the mishap and a disgruntled passenger.

My priority checked bag was not loaded on the flight. I had to sit in baggage claim in Las Vegas for 2 1/2 hours waiting for the next flight. All baggage staff were very helpful, tracking showed it as scanned for loading. Nobody told me why it wasn't on my flight.
