Ridiculous to have to pay for carry on and to pick seats

Ridiculous to have to pay for carry on and to pick seats

We did have a delay but nothing that affected our schedule to terribly. Breeze is the best budget airline that we have found for the eastern seaboard. Price is good. Baggage rates aren't terrible. I suggest checking a bag which gets you more bang for your buck. They fly into smaller airports which is so much easier than trying to get through Logan or JFK. Overall good trip.

First time flying Breeze everything went smoothly. Left early and arrived early to our destination. Definitely will be flying again with them!😊

Great! Only problem is we can’t use the northbound flight on this route as it arrives much too late and is not non-stop.

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.

Our gate was changed twice, but since they were super close it wasn't an issue. We were delayed 90 mins or so, which wasn't great, but sometimes that's just what happens. Communication was the issue. We weren't kept informed about delays--with more information I would have gotten a real meal, taken a "bio break" and purchased a new book. Because another. flight was being updated more frequently about their delays, I thought ours would be shorter and stayed close by. It left me feeling more frustrated than was necessary.

Your feedback should include a "not applicable" button. There was no food, nor entertainment on our flight. Also, a snack on a short flight will be nice to have

Boarding at BDL gate 24 was confused, but balanced out by friendly, responsive gate attendants. The crew were friendly and made for a straightforward flight. Seats were fine, but the aircraft needs to go in for cabin maintenance. The air nozzles overhead were all loose and could not be closed or adjusted.

Head rest did not move, very uncomfortable. Staff was great. There was no entertainment, would be nice not to have to pay for snack.

Worst airline - on our flight down from MCO to EYW, there was a huuuuuge delay. We were supposed to take off 12p and it was pushed back to almost 2:30p. We boarded the plane and then sat on the tarmac forever because we were "over" weight and had to burn fuel. Rather than ask guests to volunteer and leave, they kept us on the plane. Finally a family decided to off board and take their luggage with them. Shortly after, we left the terminal but then the pilot told us we may have to sit at the end of the runway for 15-20mins to burn more fuel. Which we ended up doing and of course it started to rain. We finally took off 2:50p. We were supposed to land 1p and didn't land until 3:45p. Basically had time to scramble off the plane, grab our luggage, request transportation to our hotel, unpack, rinse off and hustle over to our 6:30p dinner ressy. It's a shame Breeze is the only non-stop airline from MCO to EYW. For this, not sure I'd ever go back to EYW - most def will not take Breeze again.

Ever since Southwest starting charging for bags, passengers don't want to pay to check their bags, so the gate agents have to beg people to check their roller bags now because there's "not enough space". This was a terrible business move by Southwest.

Full cans of soda would be nice. A choice between two snacks would be appreciated.

Tried watching free movie and it kept freezing so I couldn’t finish.

All was good. I just had a hard time getting connected to the WiFi/internet during the flight

Sacrament staff are always polite and helpful. Airport is easy to maneuver and boarding is straightforward.

Great flight. Outstanding Service. Southwest was able to put us on a direct flight to Denver when the connection could have been affected by a later arrival to Baltimore. The direct flight was less expensive that the flight with the connection in Baltimore.

Delays delays delays. Late taking off, late landing, wait for a gate, etc.

Flight was delayed due to plane not passing inspection And one of the crew had to time out and we had to wait for another one A 3 hour delay

The quality of Southwest Airlines continues to degrade each time I fly with them. If it were not for the free luggage, I would probably choose another airline. Their prices are a little bit competitive, but way too high for the quality of the service. Southwest is not unique in this way. Domestic flight in the United States of America has continued to be a lower and lower quality product. Very sad when you compare the quality of domestic airlines to that of many international airlines around the world.

It was one and half hour late... Not sure if any other experience matters.

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.

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.

My JetBlue experience was nice. The flights ran on time, the aircraft was clean and comfortable, and the flight attendants were attentive. My only issue, which is isolated to the low-cost (budget) option at JetBlue, is that the check in process makes the user feel that they have to buy their seats. The seats offered for purchase are upgrades from the budget seats you get (which are essentially the last seats remaining). The interface should not make it feel like you must purchase a seat.

I especially liked the lead crew officer. His boarding and safety announcements were made with a bit of novelty and humor. The flight also left the gate 10 minutes early and we landed about 20 minutes early… It was a delightful flight…

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

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.

It took 1-1/2 hours to get our luggage after we landed. That to me is unacceptable

Overall was excellent. Will definitely us JetBlue in the future.

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.

Excessive fees for flight delays. What a Scam. I was not able to attend the wedding I needed to go.

It was terrible, we had to board and unboard the flight with a hour delay that caused me to miss an appointment and a surprise for my wife

Great! I intend to use Spirit for future flights. No complaints .

They cancelled the flight 3 hours prior departure. Had to spend $400 for a ne way flight with Delta Airlines! Spirit Airlines are not serios!

Plastic seat really hurt my back. Cannot even recline on the flight. Very hard to sleep on the plane due to terrible seats . Food and drinks were expensive and not very good. There were like 2 open exit rows behind me. My isle was full so I asked flight attendants if I could sit there. They told me it was a safety issue??? I think it more unsafe to have no one sitting there. In case of emergency, you’d want someone there to help.

The entire staff from check in agents to flight attendants were pleasant and professional. Would suggest a complimentary water.

Very easy boarding! Crew was fantastic and offered us refreshments quickly and efficiently. Quick, nice flight!

My baggage broke and they did not offer me anything. No conversation

It was not good at all, I think the crew could be kinder

Cheap flight but really uncomfortable. Seat cushions flimsy. Jammed in middle seat when flight is not full. They don’t even give you water

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.

It was well done. It was my first time flying with them and I was nervous b/c I have heard of many cancelled and/or delray flights. Everything went smoothly.

Frontier is the Walmart of airlines. Frontier has removed adjustability and comfort from their seats to make the flight lighter and save gas. This makes it impossible to sleep on their flights. Their customer service is abysmal. Once, I bought a drink on the plane, and they swiped my credit card on the plane to pay for it. Then I got three weeks of daily notices from my bank telling me they tried to charge the wrong card number over and over again. I tried to call them, but they removed the ability to actually talk to someone that can resolve such a problem from their company to cut corners. The only way to talk to someone in person is to go to the check-in counter at the airport (40 minutes drive from my house). Eventually their system gave up on trying to charge the card, after 21 days of repeated tries. They don't pad their prices even a little to handle customer service issues like missed flights. They also have a blanket policy preventing helping you reschedule a missed flight if their system says you "cancelled" your own flight online. This is a major problem because their website is broken on mobile devices, the only web browser you have at the airport when their gate staff tell you that you have to reschedule your own missed flight online because they can't help you. I tried to reschedule my flight on my android device and instead, their website crashed and "cancelled" my missed flight. When I got to the counter, the agent argued with me for 5 minutes insisting that I intentionally cancelled my own flight (implying I had to buy another flight). She missed the point: the problem was that I could not buy another flight because their website is broken. I left to avoid more conflict with the "customer service" agent. I tried to redress my issue with their only other "customer service" chanel available: the contact form on their website. The response I got was more of the same: you cancelled your own flight, according to our website / computer records, therefore we won't help you. I was trying to explain the problem with their broken website that cost me hundreds of dollars by crashing / malfunctioning and resulting in a cancelled flight, but they only had deaf ears for this problem. Worst customer service I have ever experienced. I will never buy another Frontier flight again, because it is a risky, painful move that I will likely regret often.

I was 2 hr arrive in the airport and 45 min in the line . After take to my turn . The agent tell me I’m later . I can not board . So my vacation was going to the floor . Just for their bad customer service agent in the airline

2 hour delay due to late plane, wrong size plane causing overbooking, and people getting off and on the plane after boarding was completed.

Since you have to pay for overhead bags then they shouldn't be running out of space and asking individuals who paid to remove stuff from the overhead

Book with frontier airlines with the mentality that they'll cancel your flight, kick you off and lose your luggage. Anything besides that is a win. Compare prices with other airlines (to include luggage) and if frontier is still worth it, book it but know all of their policies.

You get what you pay for nothing essentially but a hard uncomfortable seat that doesn’t recline and kids screaming all around you and chaotic boarding and limited check bag weight allowance when compared to other airlines

Not very good. Paid in excess of $400 for assigned seating for my family and that was not provided. I want that money back.

I chose the seats when booked the flight and paid for them. However after checking in I found we were assigned different seats!
