The only thing that would make the experience better is a little more leg room and the overhead bins are very low. I hit my head when I was settling into the middle seat and was nervous about poking my eye on the corner of a lowered bin when I was deplaning.

The only thing that would make the experience better is a little more leg room and the overhead bins are very low. I hit my head when I was settling into the middle seat and was nervous about poking my eye on the corner of a lowered bin when I was deplaning.

It helps manage expectations to know that this is a discount airline. I brought my own snacks so that I wouldn't have to buy something if I got hungry or thirsty for soda during the flight. One of my seat mates was unaware that he would have to pay $4 for a Coke and was a bit upset. He hadn't listened to the flight attendant say "Drinks for purchase?". All of the employees I interacted with were friendly and professional. My one complaint is that the overhead bins are very low when they are open. I was heading for the middle seat and unexpectedly hit the top of my head on the bottom of the open overhead bin. The headrests were also a little uncomfortable. But overall, for the price, it was a decent value, and I would fly Breeze again.

Flight was on time. The crew was efficient and kind.

Did not like the fact that I was charged to take on a bag I usually put in the overhead

My flight was delayed, not by much.?very good communication during fest and waiting to board.

Communication with airline electronically was difficult. No number seemed available to talk to customer service.

What could have been better is if Discover credit card would be able to purchase food

Crew was inconsistent in instructions in advising passengers about seat backs during take off. Perfunctory announcements except from cabin.

The experience with Breeze was really great. The app makes managing flights easy. You can check in on there 24 hours in advance, and your boarding pass is there, too. The flight crew and the staff at both our airports were wonderful. Snacks and drinks were reasonably priced. The seats were very comfortable, they even had adjustable headrests on every seat. The only downside is not having entertainment or Wi-Fi available onboard.

The price is amazing. I was worried about how the flight would be as I never flew then. Seats were very comfortable. We had lots of legroom. The Akron airport was really nice. Overall it didn't have the stress we usually experience with flying. Highly recommend

Fight crew was not very attentive and the bastions were gross!

Our flight was great we left Kona earlier and got into LAX almost an 1hour earlier as well. LAX AA is in repair so to get out and found our bus to get pick up was a bit confusing.

Plane was good but was delayed. probably not AA fault but caused a 1 hour delay. Seating was cramped.

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

We experience delays on departure and connecting flights resulting in 14 hour to our next departure. We were accommodated with a night's stay but was only provided a 12 dollar meals accommodation. The airlines rules state.at least 50 dollars. In any case, it can not make up for the whole day missed on our vacation in Sydney Australia.

I can say I will not be taking this airline again any time soon. Seat were uncomfortable and too tight. Lack of chair screen and little overhead space.

Plane felt so crowded and tightly packed. The chair itself was not comfortable.

It was wonderful upgrading to first. Plane was so cold thou. Crew was great. Wish there was a food option in first for such a long flight. Doesnt matter the time of day. Chintzy.

They attended to my needs as I couldn't walk and they provided a wheelchair for me.q

Poor availability of food. Cold cabin temperature. Extremely long waiting time for a flight attendant to respond to a call button signal.
