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

My experience is typically great with Breeze. This trip wasn’t any different.

This was my first experience with Breeze. The plane was cleaner and more comfortable than any other I've experienced. The process of boarding was streamlined. We boarded early and arrived at our destination 45 minutes early. The only hiccup was my ticket was rejected by TSA PreCheck and I got sent to the back of a very long line at Fort Myers. I entered my information when I bought my ticket, but it apparently didn't connect to my permanent profile. I'll correct that for next time. I was expecting an Allegiant experience, but Breeze was much more upscale. I really, really enjoyed it.

Great experience. Non stop is great in and of itself.

Lady at check in counter helped me get a seat in the cut row all to myself.

It was great except the other passengers who didnt have children complaining and not giving grace to the mommas with tiny babies who were trying to comfort their little ones during the decent. They were clearly trying and every child travels different.

It was pretty good. Only thing that makes our boarding uncomfortable was, that we had to pass TSA at terminal 1 and after that walk 15 minutes to terminal B, because bus was insufficient to take so many people and waiting time for the bus was more then 1 hour.

Something about the chair was uncomfortable, Maine the curvature of the back.

I would have liked to listen to music and that was not a choice. Would have liked a meal on almost 5 hour flight. 1st class not as nice as others.

Nice aircraft but no in flight entertainment was disappointing. I felt nickel and dimed to death having to pay for my seat, my carry-on and then my soda!

The boarding and seat assignment system no longer works for me, but I know it is being replaced. Otherwise, I am good with the overall experience.

The lead steward kept singing about "San Francisco" and hotel California---more annoying than humorous....needs work. Flight was smooth and on time.

Still a fan of open seating. Flight was on schedule and arrived on time. The 737 MAX is very comfortable.

Airline travel is always too cramped to really be pleasant, but the cabin crew on this flight did a pretty good job of making up for it by putting on some music during boarding and sprinkling a few funny remarks into the safety briefing and announcements, and just generally being friendly and helpful. It definitely reminded me of why I prefer the in-flight experience on Southwest!

No delays and arrived to destination 30 min early. Staff was super friendly.

San Diego airport is brand new, spacious, airy and very smooth checkin at SW baggage drop.

It was rough. The staff was unprofessional, the choice of on board drinks terrible, it was cramped in space at every airport, they always ran out of overhead bin space so they pressured people to check bags for free or we couldn’t leave on the plane— so I did check my bag to help, and they nearly lost my bag. My bag did not arrive on the luggage belt, another man on my flight and I had to waste our time going to the baggage office to search for our bags. I would only fly southwest again if it was my last choice. Also, my flights were consistently delayed over and over again— at one point they straight up told us we were waiting for the pilot to arrive.

Crew could have been friendlier, maybe I'm spoiled by SW crews. In flight wifi was good. Would be nice to have more food offerings on a 4 plus hour flight

Had to get off plane from prior flight even though I had to reboard same plane to continue to my final destination.

Everything a cheap airline should be at normal airline rates.

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.

No food or entertainment, but flight very comfortable and on time.

Baggage claim was barbaric at Wilmington. I realize that this is a startup airline but if they hope to grow or even survive they need to upgrade this airport. There is no automated luggage carousel and at times you are not only fighting your fellow passengers to get to your bags but also passengers coming in from other flights who cross right in front of you

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.

flight was delayed for hours with no explanation. The plane was a very old aircraft.

Communication since no reason or explanation was given for 3 hrs delay

The flight departed more than 1 hour late. Leg room is bigger than most airlines

Excellent. Although they used to greet me as a mosaic member and provide a free drink, early boarding helps me to keep coming back to JetBlue.

No music app working: no economy meal on five hour flight; hour on tarmac at the end waiting for a gate. Flight itself was smooth and easy.

Communication with the customer and stay is important. Staff off with a minor inconvenience but it worked out of course. Also this was a very old Mint Class plane. They snuck this one in on us. The updated aircraft are much better.

Not clean and was told I would get a great seat and it was not great at all

Flight got delayed for 5 hours no good explanation was offered ;(

Horrible. I would never fly Frontier again. The booking process is tricky at best, but fraudulent in my opinion. Frontier customer service did nothing to rectify my purchase -- I ended up paying more than double what I could have gotten from other airlines and nearly triple what I thought I was buying from Frontier. Their booking practices are unfair to the consumer.

Delayed. Text notifications were slow. Not much information o what was happening. Boarding was slow and confusing. Wasn’t even offered water other flight. Had to ask. No entertainment at all. Felt like.a Greyhound bus.

When I wanted to check in 3 hours prior to boarding time, the employees mentioned “a little over an hour delay” so I waited for an hour then I went to go look for food in the terminal and most people from that flight were in the same area looking for food. Finally I decided after food to check to see if it’s anytime closer and now it’s 2 mins until boarding closes?! What are you kidding me? I didn’t receive anything via sms about boarding now nor via email or on the intercom. I luckily made it through, barely, and then there’s no room for my carry on mind you I’m in the very first row so I had to place my purse in one further row back and my carry on sections down. Not sure who pays for better seats to get your stuff placed all over the plane but that was the worst experience I’ve ever had flying with anyone.

Better than expected. Staff were friendly and nice on both flights.

There was no one at the counter to assist with our check in. The app didn’t work, so I arrived at the airport with time to check in and I couldn’t because no employees were there. When I finally got someone on the phone, it was inside the 60min rule and they said I could no longer check in and they could sell me another ticket. We had to scramble and pay an additional $800 for tickets and THEN AFTER (about 60 min from my original convo with customer service and 10min after original departure time) I had boarded my new flight, there was email saying my original flight from Frontier was delayed and leaving 2hr 50min later, but I STILL wouldn’t have been able to check in. Which means customer service should have been able to see it and let me check in because I was well within my check in time. When I call Frontier, they hang up on me. So their app didn’t work and they employees left and they take zero responsibility or assistance with their “customer service”

Terrible. Flight cancelled with no reasoning and no flights to rebook. Employees were useless and did nothing to help. Did not even know where to retrieve luggage from the cancelled flight. Flyers beware.

No fault of Frontier staff: plane was very late, reached Orlando at 1 am, took a while to get luggage. Weather, gov financial shutdown impact on TSA, air controllers seemed to have multiple flights backed up. Frontier staff seemed to cope as gracefully as possible. It did reassure me that I and my new hip could adapt to travel challenges. Food/entertainment were irrelevant to my trip.

Terrible. The canceled my entire flight when I requested a refund for a trip frontier canceled trip one way.
