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 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.

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

It was easy and very comfortable! The crew was accommodating and cheerful. I enjoyed myself!

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.

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.

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!

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.

overall the crew onboarding and providing service during our flight was great; they were friendly and helpful. I said ok to the entertainment because there was none, but the crew explained why which was very helpful. I am a diabetic and the type of snacks are not diabetic friendly (full of carbs and sugar). However, I am always prepared because I know the catering is for the larger population.

We were skipped when the snack cart passed and then the attendant said we weren’t . I am disabled and was in a row toward the back of the plane which was very difficult for me to navigate. Disabled people should not be forced to walk the plank.

Flight was delayed and then "they did not have time to load food". No snack or drink at all for 1.5 how flight. Somebody wasn't prepared.

It is usually very pleasant. Good service for the price, international flights are even better

New high end luggage ruined/zippers broken, items missing. All happened on return flight from msp to mso. Do better! Not store bought luggage but high end personalized ogio custom embroidered luggage. Total slap in the face ontop of an extra luggage fee that took me 3 hrs on chat to resolve.

Third flight in two months where the crew was not there. Comfort seating does not guarantee overhead bin space. Passengers with children are allowed on the plane first - if you are flying to and from Orlando, this means half the plane has boarded before you get on. And somehow all the bin space is taken up. 3 out of 5 flights have had issues with equipment or procedure. Some of these instances caused the flight to be delayed because of a "nuisance" light. One time it was a bag that had been brought on board but did not belong to anyone so we had to return to the gate. Last night we were told the "AC" on the plane doesn't work well and we're 10th for take off- because the crew was late - and that it will get cool when we're in the air. Not sure if this is usual, but I didn't think flight crew could jump seat in first class. Movie and TV selection has not been refreshed for several months- flying one to two round trips each month easily exhausts the list of content.

Definitely a southern flavor. Cordiality was evident even though no drinks or snacks were served.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

The only real hiccups in the flight were things beyond Delta’s control - turbulence which delayed food service and a departure delay caused by some VIP plane which stopped all departures and landings for 30 minutes - and was never explained to us by the crew. Otherwise good flight. I would fly Delta again.

The plane was frigid, and leaked water from the ceiling all over me and my seat.

Did not know that they didn’t have screens for entertainment. I didn’t have headphones so I couldn’t watch anything on my phone.

Gate 461 the worst in LAX Boarding lacks professionalism And as usual, your food sucks.

Flight was fine, but not having WiFi was a major negative

I was trying to take 2 one and a half hour one way trips and I experienced almost 20 delays over the course of those two trips. Only a few of them were due to weather the rest was disorganization

Would have thought that they would gas up plane before everyone got on board

The flights were terribly delayed and then cancelled which forced us booking another night at the hotel. Very poor management from American Airlines

American switched my flight to a 5 hour layover then cancelled my whole reservation with no notice and refused refund. Won’t fly with them again.

We sat on runway for an 1 hour because they were short handed at key west airport was not fun

The WiFi and app don’t work as easily as other airlines

Late. Then next flight was an hour late due to mx.

You did a great job rescheduling my cancelled flight. However, you made me pay for two seats for $118 even though the seats on the original flight were free. I think that was a very unfair thing to do.

The flight was on time the crew was courteous that makes for a good flight.

I liked the entertainment on JetBlue, the service from JFK to JAX was terrible at best

I usually dont fly JeTBlue and I dont think I will ever do it again. The flight was delayed fee time, nobody was giving us any info at at the airport, gate changing, the slowest and poorly organized boarding ever, rude staff.. huh

Like the variety of entertainment options. One crew member was a little on the rough/rude side. Boarding was a mess, attendants didn't do a great job of helping with the luggage storage and it delayed us a couple of minutes.

Flight is delayed by more than an hour without any reason, the jet blue gates kept changing every 20 mins and there is no proper communication. No ear phones provided in flight, there is a screen with entertainment but what is the use, I have earphones but the console has outdated audio connections, no usb C or bluetooth, they are living 15 years behind

Flight was cancelled, no support at JFK even though it is their main hub.. wait times on the phone was very long

I liked the punctuality, the crew, and overall the whole flight

When I agreed to give up my two seats because of overbooking by the airline, I should have been offered some sort of reward or credit towards a future flight. I was not. It was not until the next day when I mentioned it to a Jet Blue employee that I was advised to call 1-800-JetBlue. So here I am, having done Jet Blue a favor and I had to do the work to find out if I was going to get a credit. Such service

It's not JetBlues fault but there was a smell on the plane (possibly other travelers) and 3 children behind me that never quit whining. Soccor fans that were very loud. Pilot brought the plane down from high altitude quickly, dropping us hu dress of feet at a time. I've never felt that intense of dropping on other airlines (usually fly Southwest Airlines). But I arrived safely and I'm thankful for that.
