Unfortunately, I left my headphone's case in the bag of the front seat. I was seating on 9C. Hopefully the found it and I can get it back. I have not been able to get in contact with Southwest. Other than that, everything went fine.

Unfortunately, I left my headphone's case in the bag of the front seat. I was seating on 9C. Hopefully the found it and I can get it back. I have not been able to get in contact with Southwest. Other than that, everything went fine.

Maybe different snack selection. To much sodium in them. I know refrigerators are not available but there has to be healthier items.

Wifi was terrible. I couldn't get any work done on the long flight

It's a shame that SW was previously my preferred carrier until they started imposing all these fees (luggage, seats,etc) and pulling back on other perks. I only flew with them this time due to time frame I needed to be at destination. Wasn't provided gate info during check-in, Gate info wasn't displayed at airport until last minute, gate info didn't match what SW personnel announced at fate. Kind of a mess.

Flight was fine. Only thing was flight was delayed nearly 2 hours. Flight was originally scheduled to depart at 7:50pm but didn't depart until 9:50pm. I got home around midnight. It was later than desired and I had to get up early next day to take kids to practice. I have noticed that last flight of day on West Coast for Southwest always tend to have delays.

Wasn't expecting this, but, we actually ended up getting assigned to the first row of seats!!!!! The extra legroom came in handy

Trash experience on all my flights this week. Delay after delay. The flight I’m waiting for has been delayed 6 times and nearly 3 hours.

Fairly good - the seats seemed more comfortable on this flight. The staff out of Detroit were quite friendly. But they directed us to the wrong carousel for luggage. :(

Southwest's seats are the least comfortable I have ever sat in.

Southwest is a discount airline. I get it. You take the (usually) good pricing with the bad (cramped). But Southwest is becoming more and more like the cut-rate airlines *cough* Spirit *cough*. It used to actually be a fun experience. e.g. paying for WiFi is bad enough - having to pay for it on each leg of a flight is ridiculous. Yes, I've seen your numbers that it only "impacts a small percentage", but you and I both know that is misleading at best. While I used to try to fly SW exclusively when flying domestically, now I'll look elsewhere very frequently and price being equal (or close) I'm going to the other carriers.

Great quik boarding, friendly gate agent and crew. Let early

We sat at the gate for over 30 minutes, with no indication as to why

All was fine. Small plane so no food or entertainment.

Very aggressive at the boarding area of only allowing one person passed a line/ sign

Delayed 7 hours Crew and employees were nice Extra long flight but at least we got in

I love how the flight crews are now saying what the weather will be like, when we can expect to be able to get up and use the restrooms etc. I have to say also that our flight crews this trip were incredible - fast and courteous - and somehow managed to do the service even on these short flights with a few bumps. The only reason for an ok rating on entertainment was because these short flights are on planes without seatback displays but that's ok because I just download shows on my iPhone beforehand.

Our flight from Detroit to LaGuardia on Thursday 8/20 was delayed from 555 to 910 due to storms and a ground stop at LGA. It’s never fun to be stuck at the airport but I thought the desk crew and captain handled it well and kept us informed. I especially liked how they referred to us as their “LaGuardia family.” I am a loyal delta customer and this is one of the reasons why.

I missed the flight because the Minneapolis flight was 49 minutes LATE, and the Boise flight LEFT 24 minutes EARLY!

No wheel chair as requested at Atlanta arrival on first flight.

Having to up charge for a seat assignment is not good. Delta can do better

Price was crazy watch it if you Chan he your flight

The price. Omg $1100. Was crazy and it was not clear on the website.

Excellent. I had a medical emergency on flight SNA-ORD and the attendants were very helpful.

This flight is a quick way to get to Chicago, but a bit expensive.

We got delayed three hours and nobody thought to have the bathroom fixed while we were sitting waiting to board? took a full hour to have maintenance come and check it off. Had to shut the bathroom down twice so that the pilots could go to the bathroom. Everyone missed their connections.

Not good - outbound flight was delayed and missed my connection even though I got to the gate after running through the airport - the agent would not let me on because the door was closed (flight had not left). There was no notification from United - overall experience was very disappointing. Additionally, I was downgraded from first class to coach on the alternative flight

I liked that the flight was nonstop from ORD to CIU for $200 round trip.

Some sort of compensation for missing work because of a cancelled flight that was United’s fault

I was told we'd have a hot breakfast option in first class, so I chose not get a hot breakfast. It was a very strange meal, but the fresh fruit was very good quality. Service was excellent from ORD to ELP. No service from MBS to ORD, not even water. However, when flying American from FNT to ORD, which is a shorter flight, they at least pass out snacks and offer water.

Staff friendly and app worked really well. Modest delays were frustrating

I sat in seat 22D near the back right of the plane. My phone battery was getting low, so I plugged my charger into the power outlets below the seats in front of me. They did not work. When I asked the flight attendant whether this was the case for the whole plane he said, "No. It's only this one. It hasn't worked for months". This should be noted to whomever services this plane so that maintenance can fix this for future passengers. I was on Flight AA5614 from Grand Rapids to Philadelphia on Wednesday, September 23, 2026.

Flight delays for communication overall not a good experience uncomfortable on the plane. Person in front of me reclined his seat, putting them inches from my lap.

The passenger in front of of me reclined their seat back all the way the entire flight. Their headrest was in my face the entire flight! I barely had room for the little plastic cup of water to fit on my tray table; can you make the seats and space between the rows any smaller??? You can’t even get up to use the restroom! Worst flight I’ve had in a very long time!

the plane was so hot!! the air-conditioning was barely blowing. The flight was delayed, and we had to sit on the hot plane before take off for an extended amount of time, waiting on international passengers. Would not have been so bad if it was not so hot. They said it would get better after take off, but it did not.

They should have allowed for extra time to de-ice the plane before boarding passengers. This delayed us about 10-15 mins after we boarded. Overall experience was fine. Crew was friendly and on top of everything. We didn’t have any issues during the flight.

Everything was excellent. I loved my flight Thank you so much 😊

I wish the indicator on the side of each row was easier to decipher regarding which seat was the window, middle and row seat. Otherwise, no complains.

Turbulence was bad and flight attendants gossiped about going to the bar and dating. Could have better awareness.

First of all the check in was terrible . No customer service treated us like we are lucky to fly on American . And kayak never notified us of flight changes , I think we got a text at 3 in the morning before our flight . Charges for seats and luggage ! Really flying is just plain stressful .
