Boarding process of asking for volunteers to check bags goes against the system you had before with 2 bags checked free. This process is more of a guilt trip than a caring attitude toward the customer. In addition bag-size scrutiny has increased which also slows down the process of boarding. My wife said she will not fly on your airline again unless there is no other option.

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

I wish they had movie screens in the headrests. The seats are much improved, more legroom and recently renovated. Bathroom was clean. Staff was outstanding!!

My original flight was extremely delayed but I was able to join the standby list for an earlier flight. I was grateful for this feature but I wish I could’ve gotten my standby confirmation sooner.

Glad flight made it out. So many delays due to hurricane. everyone did a great job.

Very good. Exactly what I expected. We did have a slight delay.

The trip was good. Short, uneventful, and can't ask for more than that My one complaint is that I had signed up for wheel chair assist between gates. I fractured my foot/ankle in two places and needed the help. Neither flight did the requested help appear. I ended up walking through both Atlanta and Nashville Airport and was a very unhappy traveler. While I know that it's the airport responsibility for the service, I wish that SW had at least verified that the assistance was there as requested.

I liked that we arrived safely. I did not like how Southwest personnel blamed the boarding delays on wheel chair passengers. If there is a national wheelchair basketball tournament occurring, be ready as a company to respond with appropriate resources to match your cudtomers needs.

I love Southwest! I try not to fly with anyone else!

Lost cabin pressure and had go back to the originating airport. We were left sitting on the plane for more than 30 minutes with no directions from Southwest on what was going on, other than the app telling us there would be a flight at 12:30 AM. I finally got off and went directly to a SW desk and rebooked for the next day. I understand that malfunctions happen, but SW was totally unprepared to manage the situation and did not serve the passengers. To make matters worse, they took one hour to find my checked bag.

Efficient boarding and early departure. Very smooth flight. Early arrival in ATL. Great flight.

Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

Lost luggage, they need a baggage service representative available all times in Atlanta

I was charged for my daughters bag when I am supposed to receive two free checked bags with my United Explorer card.

Made all groups except 2 check despite ample bin space. Inflight WiFi and entertainment didn’t work most of the time.

The check-in process is not the best They should have agents in site to help with any problem especially a rebook. Why does one have to get on the phone when there were at least 8 agents around that could have help?! Flying is stressful as it is and having someone willing to do their customer service will ease some of the stress.

Flight was quite late as there was no pilot Crew is usually excellent, this flight not as good as usual there were more mistakes, slower and less friendly service But honestly the aircraft was too cramped and uncomfortable for a 4 hour flying get so, do to the aircraft liability the very best you could ever do is mediocre.

The pairing of personal Bluetooth headset did not work, provided headset did not work, then the screen locked and therefore no in-flight entertainment was available.

The staff was so kind and very helpful. I had to use handicap wheelchair services and was so thankful for how well they treated me during my whole trip. Thank you so much. Jessie took time to explain his service and what part he played and how others was going to be available to help. The flight attendants was so helpful in helping me get to my seat. Made me want to plan my next trip with United Airlines. I usually use Delta.

WiFi never works on any flight and the attendants can never get it to work. You would think paying so much for business/first would give WiFi. Also, the food in business is really poor these days.

There were alot of delays without any information. First, my original flight was overbooked so I volunteered to stay back. The layover was hell, I sat in the airport for 4 hours. I was highly disappointed because no one was around to provide answers.

The flight was delayed 4 hours, and when we finally boarded, they told us that the fuel was only just then checked. So, we waited even longer to take off.

Flight was extremely hot and they made us check our bags when the space was nowhere near full

The only thing to like was that we eventually got to our destination

Finding the gate was very confusing. Our boarding pass listed one gate and the staff verbally told us a different gate.

Our 8:45 am flight kept getting delayed. Boarded after a 2 hour delay only to be taken off the plane again. At 12:30 pm, we are told there was a new plane and we had to change terminals. Flight was delayed again to 1:50 pm. Eventually boarded again only to be on the plane for over an hour. Flight finally took off at 3:30 pm. 7 hours after original scheduled time. To top it off, couldn’t even get coffee on the plane due to turbulence.

16 Hours delayed, NOT because of the cybersecurity Microsoft issue, but because we were one flight attendant short, then when the missing flight attendant showed up two hours later, the flying shift of our pilot had expired, so, now no pilot. American Airlines is the new Spirit Airlines, actually, that is not fair for Spirit, they are probably better.

My previous flight was late and did not connect properly. The gate was closed and I missed this flight.

The agents at the gate were rude. The stwards were pleasant. The seats were comfortable. The tray table had crumbs on it. A passenger talked constantlt and very loudly for the entire flight annoying many passengers. The stewards did not ask her to speak in a lower voice but my travel partner did.

Had to rush between flights due to first leg being late, then pulled for additional security screening and attendants were in no hurry, took other people at same time as my husband and I further delaying us and causing additional stress.
