I have never flown on Breeze, but relatives who live in another state have and didn't mention any issues. Some of the airports they fly out of are smaller and makes travel very convenient if you live near that airport. With any airline, you need to compare the total price of all of the add-ins to make sure you are comparing apples to apples. Some airlines have lower 'base' fares but once you add in all of the various upcharges, not such a bargain. Make sure to check the actual flight information since a 'direct' flight it NOT the same thing as non-stop, but many seem to use those terms interchangeably. Avoids a surprise when traveling.
I have also seen some airlines show they have service from A to B but there is some VERY long layover (8+ hrs) in city C. In the past they would show they don't have service from A to B. Make sure you understand the total duration of any flight you plan to purchase.
