Flying with this airline is a true nightmare. We got delayed than stranded on layovers due to maintenance issues both ways of our flight and there’s no way to communicate with anyone other than AI bots that are absolutely useless. Never again.

Flying with this airline is a true nightmare. We got delayed than stranded on layovers due to maintenance issues both ways of our flight and there’s no way to communicate with anyone other than AI bots that are absolutely useless. Never again.

Flight was great except for lunatic lady and her mother sitting middle/window who went nuts when the woman on the aisle wouldn’t stand up right away to let them out even though the aisle was full. Police had to be called. Some people just shouldn’t be allowed to fly.

Flight attendants were wonderful. Seats were comfortable “Nicest” bundle). No screens or meal, but it is a budget airline.

it is an economy airline so lack of perks expected .. however an efficient board, clean plane, pleasant crew and an early arrival for half the price of full service airline

Given some type of snack. Had staff that hated their job and life in general. Have regular overhead bins. The bags have to go sideways and even then, they barely fit. The seats in the front - what would be considered business class were nice. Nothing extra but nice for a short flight. But the regular seats were so close I have no idea how people even fit it them.

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

Well, Kayak should have communicated with Breeze that when I purchased the ticket, Kayak should have relayed that I had one carry on as part of my ticket purchase. So, KAYAK, tell the airlines!

Why do I need to spend $$$ to sit together as a family? It’s beyond frustrating, we were all sitting apart.

Flights were consistently delayed and we were given no reason for the delays. We could not check our bags until two hours before the flight boarded in Myrtle Beach, even though we were there and there was someone manning the check-in at the terminal. It is also asinine to charge $70 to check your luggage at the terminal, but charge $35 if you choose to check your luggage via the Breeze app. The seats were comfortable enough and the flights were quick once we actually got on the plane and off the tarmac. But again, we were constantly delayed.

Prior to boarding we were told the flight was still on time up until about 20 minutes after the scheduled departure time. Details on the new departure time and gate were not provided to us in a timely fashion and we were lead to board a flight to Pittsburgh only to realized upon scanning my boarding pass that it was the wrong flight when signage at the gate said Providence. However, once on board the plane was comfortable and staff courteous and nice.
