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.

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.

Boarded on time but once we were ready for take off, the crew determined that, although every seat was taken, somehow someone was on the wrong flight. Delay, delay delay, announcements and ended up with one person checking EVERY ID against their passenger Manifest only to figure out it was a "clerical error." We departed 54 minutes late causing me to run in the St. Louis Airport to make my connection and lose the priority boarding spot I had paid for. Unnecessary delay.

I was re-booked onto another flight because my original flight was delayed and I would have missed my connector. I ended up in the “C” group after paying extra to be in the “A “ group on the original flight. At least if you’re going to re-book people, re-book them into the same group.

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

mandatory demand customer to check their carry on because not enough people check bags.

Connecting flight is on time and boarding was a breeze!

Excellent. Would encourage Southwest to keep current boarding procedures with free style seating. Makes for a fantastic experience

As always, the entire Southwest experience was perfect. Purchasing the tickets on the Southwest web site was effortless, departure and arrival gates were spotless and comfortable, plane was clean and comfortable, crew was excellent and flight was on time. Wheelchair service in Las Vegas at departure was somewhat chaotic and disjointed, but I am not sure if that was Southwest problem, airport problem or combination.

I wish they had movie screens in the headrests. The seats are much improved, more legroom and recently renovated. Bathroom was clean. Staff was outstanding!!

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.

Seats are not very comfortable, maybe a little more padding for a 2hr plus flight

Very sad about what Spirit has become, because the flights I had with them were delayed between an hour and a half and two, terrible service

Vegas is such a quick flight that amenities aren’t the important part, in my opinion. Just get me there efficiently and safely, and that’s exactly what they did!

The flight was severely delayed due to the missing flight attendants.

Absolutely horrible. Usually pay $40-$50 to check luggage in. I tried to check my suitcase in and the price is raised to $70. That's ridiculously greedy c'mon. I had to leave my suitcase with all my clothes and hygiene products and repurchase once i landed in Atlanta. You guys make it really stressful to travel. Don't even want to travel anymore.

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!

My luggage didn’t arrive at LAX, so that wasn’t a good experience.

Terrible seat, no in flight entertainment. No complimentary food or drinks. Seats really hurt my back after flying spirit for the day.

Great experience for my first time on Spirit. Wey clean plane, great staff, very smooth. Gave food and entertainment “poor” simply because there was no option for NA….i did not get food nor did I order WiFi….so not a fair assessment but neither would giving top marks without experiencing. Overall, great experience.

Everything was fine. I'm average height and I pack light. I'm ready for my Spirit flight.

Boarding was on time and plane departed as scheduled. There are obviously no amenities (food, drink, entertainment) on Frontier, but there also didn't seem to be any issues with luggage space either.

Inbound plane was on time and flight departed on time with no issues while boarding.

I knew going into this that Frontier, being a low cost carrier, would be pretty bare bones and charge for most extras but this was made up for by the fact that the airplane was a reasonably new Airbus, every employee was great and best of all, Everett Washington is an amazing airport - thanks Frontier for flying there!!!

i was unable to check in the flight. refund requested

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.

Just know that everything, and I mean everything is “ala cart”. 60$ just to put something in the overhead bin. I will never fly Frontier again nor do I recommend them to anyone else.

The single worst check in experience I could imagine. I’ll never do any business with Frontier or any affiliated company

Too many extra fees, uncomfortable, little leg room. Will not recommend this airline.

Everyone seemed to be in zone 1 for boarding. Maybe break it up a little. Otherwise, smooth flight.

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.
