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.

Comfortable seating, adequate space available, nice to have USB port, polite crew.

Long layover between flights to Long Island from BWI - need better coordination between flights

I elected to pay for the upgrades and found very little difference

The new seating arrangement is so over priced for what you get.

The problem with the seat assignments is that there were a lot of rows in the front that were empty but my row at the back was full. Just not so pleasant.

No food or entertainment, just a quick 40 minute flight. A little bumpy due to Santa Ana winds but pilot has no control over that. Good flight and landing!

Good but I prefer choose your own seat. With the new assigned seats they should board from the back I see no advantage to this new boarding. Just like every other airline

I realize they are still working out kinks with the new boarding process, but by the time I boarded in group 5, most of the bins were full. All airlines should better enforce small bags and jackets going under the seats until everyone has boarded.

WiFi was not working and didn’t have a beverage service

Snacks are always pretzels. Why can't you also offer peanuts ?

Flight boarded late after announcing on time boarding. Flight arrived only a little late despite late departure. Had trouble connecting to WiFi

Flight was smooth. We boarded early and left Grand Rapids about a half hour ahead of schedule. We then arrived in Lakeland about 40 minutes early. Flights attendants (3) were welcoming and pleasant. Wish we would have at least been offered to buy a bottle of water. No beverage service at all.

I really liked the young man who checked me in and took my bags! He was so kind and was very helpful! I told my sister about the great service and him and she said that is why she flies Avelo Air.

The flight was delayed by a lot and the seats are pretty tight

Surprisingly was one of the better flights I’ve been on

Short 2-hour flight, we took off on time, ETA was earlier than stated, no interaction needed with stewards, no food, no entertainment on such a short flight.

Avelo provided exactly what I expected. They are a low-cost option with no frills but the experience was comfortable and the staff was great! I will be using them in the future for trips when cost is a priority for me.

Expect nothing and you will be fine. Seats are crammed.

Terrible landing. Uncomfortable seats. Great cabin crew-helpful and pleasant!

Tight fit in middle seat but OK for short flight. Crew was more interested in talking to each other than helping passengers - strickingly dissappointing. DAB is a great airport. New Haven sucks! Excellent value for the .

Avelo is definitely a budget airline and you get what you pay for. The plane was packed and the seats were not particularly comfortable. Staff was very nice and both of our flights were on time. The one thing I wish I had known was that the staff does not show up at the airport desk to check your bags until two hours before the flight. We had a 4:30 flight and had to check out of our hotel at noon. Since we have lounge passes we planned to check our bag, go through security and hang out at the lounge until we had to board. But because we could not check our bag until 2:30, when the staff showed up, we could not go through security and access the lounge. Passengers with boarding passes and carry on luggage would not have this issue. I might fly Avelo again but would only do carry on or plan to get to the airport no sooner than two hours before check in. And I would not recommend a long flight on Avelo since there is no food or entertainment and the seats are not comfortable.

Automated scanning was slow and somewhat haphazard. Too many people were unfamiliar with the tech and were forced to learn on the fly. The hands off approach of the gate staff made it more uncomfortable. This needs work. Overall the flight and cabin crew were excellent.

Crew were fantastic and so catering and wonderful! Full score for the entire crew!

Terrible. They canceled our early morning flight after midnight on the day of and had no available flights to rebook my family on for the next 72 hours. Yet they still had other flights that were not cancelled from JFK so it couldn’t be based on the weather. It felt like they canceled the flight based on it not being profitable enough for them. I am not interested in traveling with the again. The absolute worse customer service and lack of accountability.

First time flying with JetBlue and never again. I went to the counter to request meet and assist because I'm 74 and my wife is 79. I walk with a cane and my wife is handicapped and has her own wheel chair. I told the agent that my wife and luggage was at the entrance door. The ticketing agent said to me that they don't offer meet and assist. I need to bring them our luggage and then go back and get my wife in order to get my boarding pass. As I went back to get my luggage a Southwest agent along with a TSA agent recognized the situation and came over and took my wife and luggage to the JetBlue ticketing counter alongside the line and told the JetBlue agent to issue to take our luggage as soon as they could.

Flight was fine, price was good but food onboard was abysmal. I was on there for breakfast and lunch and dinner 845am EST to 845pm GMT and all I got was a yoghurt parfait, fruit and a piece of cake. Later snacks included an ice-cream brownie and a pizza twist. I was hungry by the time I landed and the airport amenities were closed. Not happy.

Not a pleasant experience, service was poor. Didn't like it

Plane was in bad shape. TV’s and WiFi didn’t work. Plane need a refresh. Not enough room for bags.

Everything was great. I liked the text updates so that I never miss a gate change & I have all the latest info.

No internet on a flight over three hours in this age is criminal. Staff inattentive and dismissive

Worst flight experience ever flights canceled. JetBlue told us just did not even bother standing in line to come back in one and a half hours then without any information we had to go pick up all of our luggage and spend over $2000 in accommodation just to get home. JetBlue said that the next flight available for us to get home would be three days later. Absolutely absurd hasn’t offered to give us any compensation do not fly JetBlue horrible company. They said it was based on the weather and the weather is great in all locations that we would’ve been flying to total hoax. I think it’s a conspiracy theory.

Remind customers of the need to have passport or new ID for boarding.

Flight was canceled. Most upsetting was message from Kayak, stating that the flight was canceled and click with Kayak for details regarding rebook, refund details. THERE'S NO INFORMATION PROVIDED BY KAYAK EXCEPT THAT FLIGHT IS CANCELED. AND NOW THIS SURVEY TO FIND OUT HOW WAS THE FLIGHT !!!!!!!

The flight never took off and we spent 7 hours at the airport

Gate not determined until I got to the airport - hard to plan the trip to the airport.

Our flight was canceled. I will never use Kayak nor Frontier for travel again. The entire experience was a headache.

Frontier.. nickel and dime add-ons. Flight late, on time, late again, last minute gate change, arrival gate required a shuttle to the terminal. They sure keep you guessing.. if you like a little chaos and airport anxiety, this is the airline for you!

This is my second time flying with Frontier. My current experience was very favorable. The staff from the gate to the plane was friendly, warm and professional. The food options lacked in my opinion. This area needs some attention in my opinion.

First of all we hade waited 3 hours in the airplane waiting to leave. Second the return schedule was changed and it messed up my entire vaction. I won't buy never again another flight and recommend to nobody traveling with them.

There was no food and no entertainment, so I'm not sure why these are even in the survey, as my understanding is frontier does not ever offer food without a few, not even a snack, and there are no screens so unless the flight safety talk is our entertainment why ask how we liked it?. One of the flight attendants say in the back of the plane as people filed in to their seats, yelling orders about where to put baggage and telling people to hurry up. It was the least professional experience I've ever had on a flight.

Very well recently! Frontier is improving and less harrassing customer on luggages! Positive!
