Flight was delayed over 3 hours. Planes were dirty. Staff indifferent. And they serve vegan pretzels as snacks.

Flight was delayed over 3 hours. Planes were dirty. Staff indifferent. And they serve vegan pretzels as snacks.

The flight was smooth. The Southwest experience has degraded overall, but this one was okay.

The checking experience in Orlando was terrible, almost missed the flight. Too many travelers and Southwest completely understaffed.

no service at all due to turbulence. they should've at least given us snacks, there were only 10 people on the entire flight.

For the first time in a long time, the Wi-Fi actually worked the entire flight! The flight crew was amazing as usual.

Great flight. I didn't get a drink because I was asleep whole on the flight.

Love them will get a Southwest card to track my points and keep flying with them. My family and I were pleased with the services.

WiFi was not working and didn’t have a beverage service

All good except once again bags took an hour at Midway Airport Happens all the time. Ridiculous

The seats were comfortable, and the boarding process was pretty smooth.

Food was not Good Nuts came very wet & not tasting Good Main course I asked for Steak they got me Chicken because they don’t have more !!!!

It cancelled and we were unable to catch our connecting international flights.

Leaving at 7 when scheduled to leave at 4:20 - you tell me. Understood there was a ground stop. Then having to "reboot" the plane because of a lighting strike, also understood. But basically the flight was a "clusterf#$%".

On boarding crew at the airport called in the boarding numbers too early meaning before the previous line was completed resulting in later numbers getting to board ahead. Also she asked those who boarded from number 3 to have the tags in their carry-on bags and leave it in the jet bridge. Most of the overhead bins were empty though. This is more work for the ground staff in addition to more inconvenience for passengers waiting to get their carry-ons from the jet bridge.

Like the fact that the boarding was expedited. But the delay and chaos around the onboarding was not appreciated.

The flight crew were very helpful. The seats were very close together. There was barely room to sit without touching the person next to you.

I’m an EP on AA every year for more than a decade but this was a very pleasant and surprising experience. Clean and sizable plane for HOU to CHI. 5 row first class. And excellent food in first class the steak option was really good. Your flight attendants even better. Seat 5A

Gluten free snack options and meals that offer both gluten free and dairy free.

Not a bad flight but a long delay boarding and taking off due to the pilot not arriving on time.

I would have preferred a flight voucher and to hop on a different flight. Delayed over 6 hours.

Mostly excellent. However, many too many gate changes. Connecting flight at ORD changed gate 6 times.

Mechanical issues and delays. I get it but bad experience. Turned my 3 hour airport experience into a 9 hours

The baggage process at the gate was terrible. Stay was not friendly at all

Flight was delayed because of mechanical. Could not get landing space which caused me to miss my connection. Messy and not organized.

We landed slightly early but then sat in holding area waiting for our gate to clear out for about an hour, so technically we arrived one hour late at the gate at ORD. The airport may be partially responsible here, but regardless of who is responsible, it was a bad experience to be so close yet unable to get off the plane.

Delays and cancellations. Mechanics weren’t on site. Replacement plane took hours to arrive although it should have arrived within 90 minutes. Flight back was cancelled. Ended up driving over 12 hours and wasting 3 days between everything.

Little bit of trouble getting my KTN and pre-check status onto the ticket, but otherwise the counter staff were friendly and truly concerned to get it right.

The flight could have actually taken place. Canceled flight and no option to rebook that day.

The Mario was so helpful and provided amazing customer service however l have being waiting for a callback for almost a week now and have not heard anything further after l informed them l wanted to change my date of traveling because of my hospital appointment even send them proof and l was unable to use manag your booking on their website is a bit frustrating and l would appreciate an update on My request as soon as possible. And have called them times without numbers no response

Entertainment was okay not because anything was wrong but it is a short flight so having no wifi is annoying but understandable. Crew was outstanding as usual
