Airline reviews

I normally have very good experiences with Breeze. The crew is great, pricing is excellent, and the planes are new and usually clean. This time in Huntsville we were delayed, which I understand can happen, however we were moved from one gate to the opposite side of the terminal and then back again... There was a lot of confusion. Also, my seat had a lot of food crumbs still on the floor where I had to stow my bookbag, so that was a bit disappointing. Other than that, all was good. Crew was great as usual!

Our flight was delayed 7 hours. Due to a change in equipment we were downgraded from "Nicest" to "Nicer," even having to pay for a soft drink. Disappointing. To Breeze's credit that issued a $100 flight credit. A refund would have been more appreciated.

Lost my luggage and terrible experience with customer service trying to track it down

10 hour delay with minimal updates. Couldn’t leave terminal and then ended up on redeye with a dirty broken plane. It is literally impossible to reach customer service via gate agent, app, phone, text or email.

I thought that I had pre-purchased carry-on luggage and was surprised when I tried to check in that I did not have it.

Flight departure was 90 min delayed, and the boarding experience was confused, stressful, and generally poor. Additionally, the wifi on the plane was malfunctioning for all but the final 15 min of the flight into ILM.

Great experience and In love flying in and out of Provo airport

You get what you pay for. It’s like a bus but flying. No frills, no snacks. Leg room was fine, boarding was good.

Overall good. Plenty of legroom and fairly comfortable seats. No issues with capacity and the overhead been even though most people brought several carry-ons on. I don’t think Breeze really enforces the pay for a carry-on rule.

Surprised at how much I enjoyed Breeze. Paid for the Nicer upgrade which made it closer in price to a flag ship carrier but with more comfortable seats and much more leg room. Crew was polite and since we brought our food no loss there. Would make the point that the ‘have to pay for a carry-on is BS’. Most people did not and had several. Still was plenty of room in the overheads.

The entire experience from boarding to landing was amazing! The crew were very friendly. Will definitely be back.

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

First time I've had to use the disabled accommodations. And I could not have had a better experience with Southwest, i was having trouble getting from one terminal to another due to my heart failure. And the next thing I know a Southwest agent had made sure. I had a wheelchair at all my flights. Can't thank them enough.

Delayed flight, lack of information, boarding process is a mess as is the carryon luggage causing issues when leaving the plane….just a poor experience.

Comfortable. Easy. No problems. Just wish they had gf options for snacks.

The crew was very kind and made going to Hawaii relaxing and fun to look forward to! Thank you Southwest for a pleasant flight!

This leg was much better, but we did have to have a 3 hour lay o er after coming from a very exhausting hiccup with our flight from BNA to Den

We waited in the airplane for over 45 min for a southwest employee to make the flight. This cause over half the plane to miss their connecting flight in Denver. When we confronted the desk upon arrival, they told us the only flight they had was the next day leaving at 8:50 pm!!! Or they offered to get us to Burbank or LA, but after that we were on our own to get back to Santa Barbara. I paid for a flight from sba to bna bna to sba. My re entry into mom mode has been 💯 rough because of southwest mistake with my flight. And now I’m leaving to Reno tomorrow for a vballl tournament and just discovered that my leg in Vegas has me and my 3 kids on a stand by flight even though I had booked these ticket last year November!! Do better southwest!

Southwest is kind of a slum airline. It’s gotten more expensive over the years for less and less service. I am a Southwest Chase Visa card holder and was forced to choose a seat in the 26th row in the middle seat. However my wife who is a rewards member but doesn’t hold a card or anything else, gets randomly assigned a normally paid seat in row 6! How does that work?

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