Plane did no snacks and had no wifi or entertainment although the flight was 4 hours long.

My original booking was a nonstop flight. It got changed to a flight with a 6vhour layover that became a 7+ hour lay over. I'll never fly this airline again after this roundtrip is over.

I was surprised at how wonderful it was. The aircraft was clean. The crew was warm and welcoming and as a result the passengers were friendly. One warning the only free thing was water. I kind of liked picking wet hat I was willing to pay for and what I was willing to skip.

The flight wasn’t big on frills, which is fine with me. I flew into Islip MacArthur Airport, which saved me from having to go through LaGuardia to visit friends on Long Island. It was inexpensive and super convenient!

Great experience! This was my first time flying with them and I could not have been happier.

Airplane was newer and very clean, lots of space. Crew was great. There was no food and entertainment but that was expected so not an issue.

I like that the price is right! The airplane is clean and the staff is friendly. We landed safely, so that is always a gold star in my book! Great job!

Purposely delayed the flight by 2 hours and 58 minutes so that they would not have to give me the FAA mandated refund for a delay of 3 hours. Offered flight credit instead. All that is offered on board is water and coffee, everything else costs money. They charge you for carry on and checked bags. Would not fly again.

nice flight. no frills but a 3 hour flight I caught up on my sleep. Stan O

First time flying Breeze, was very impressed. I will use Breeze again.

It is southwest seat was ok. Not the most comfortable seat

I’ve always loved Southwest. No issues at all. I was flying standby and the gate agent was extremely friendly and helpful. Boarding was smooth and I was able to get a window seat in the emergency exit row. Crew was fantastic! They were very professional and accommodating. We had to divert from our destination due to weather but the flight crew kept everyone at ease and informed us of all pertinent information. Excellent flight

The price of the tickets isn't matching the flight experience. No matter how long the flight is, you're only getting pretzels. The flight attendants looked unkept and over it.

Plz don't take away free bags and free seating

The seats were a bit cramped and worn, but otherwise okay.

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

After a 3 hour layover in Denver my flight was delayed over 5 hours! No explanation; no assistance; no offer to provide compensation; no one at Southwest was willing to offer any assistance. 8 hours in the Denver airport - ridiculous!

It was a perfect flight in all aspects! Both legs!

Only one drink pass through the cabin for a 4 hour flight. Quite rough and bumpy landing.

Boarding process, crew were good. But the seats were so uncomfortable that was all I could focus on. I literally had to sit forward so that all 3 of us could fit in row. I will try to avoid Southwest in the future for any flights over 60 minutes.
