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

It was canceled. Supposedly weather. But there was no snow in Baltimore. At least we found out before driving to airport

Flight was hours late, unable to sit next to spouse, I have had so much better experiences. Substantially better, only saving grace was that it was a short flight.

I was assigned seat 7E, yet my boarding was Group 5, which caused me to have to put my luggage in the back of the plance above `19 or 20 aisle, as passengers who had boarded earlier took the overhead bins in the front. SW needs to monitor bin space and ensure that bin space above the seat are aligned to those sitting near their seats. Also the seating assignments needs to align with group number. Maybe board those last first and so on? Having said the ALL the passengers on the plane were gracious enough to allow me and other passengers in this dilema to retrieve our luggage and helped us along the way. I always love the flight staff, as always their fantastic and I can't rave about them enough!

Great vacation. Can't wait till next year for another one.

The flight crew was extremely rude and especially not helpful when our flight was delayed.

Check-in, Boarding and flight were smooth. All the employees and crew was very nice and funny. They gave the kids crayons and workbooks to keep them occupied which was a big win. I’ve flown Southwest many times and that’s the first time I’ve seen that and it is a great addition.

Okay, not wonderful. Short flight. Wi-fi didn't work properly. Stuck waiting for a gate to open upon arrival for 20 or so minutes.

They sent a notice that they were boarding an hour early. We had to leave the club and run to the gate. They said sorry, that came from corporate and was a mistake. They did not have enough seating because the flight before it had not taken off on time. They moved our gate and delayed it for an hour.

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

Terrible because it was cancelled due to volcanic ash clouds in Guatemala while all other airlines kept flying. Had to pay for a hotel to stay overnight in Houston and try to fly next day.

Overall we had a good experience during our flight from San Francisco to Houston.

Airport terminal was outdated, flight was on a small jet with no wifi

The crew made our experience extremely bad. They were rude and didn’t have anything for kids.

The power at the seat didn't work and the seat itself was difficult to adjust - this was a business class seat. Flight attendant gave me miles to compensate. The attendant was very professional and on top of his game the entire flight.

I like flying first class, and United has a nice one

Unbelievably poor service from flight attendants. They didn’t even do water service on a four hour flight. Just disrespectful.

Seats had less pitch than a regional jet. Food was OK. Have to buy alcohol on US based carriers flying international. Boarding was a mess. Did not have bags but overhead space was gone quick. Would like to see the airlines enforce the one bag over and one bag under policy

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Crew was excellent. This was a relatively long flight though and had very little leg room, and no entertainment.

Check in was rough because the check in crew did not know how to manage my international visa documents. Required a long process and 4 people to finally be able to proceed to security. They told us incorrect information several times before acknowledging we did indeed have everything we needed from the start.

Mechanical issue delayed us 2hrs and then once we landed sat on tarmac for 30mins because someone left a vehicle in front of the gaye

Plane from partner PSA was filthy. Plastic needs to be thoroughly cleaned. Really disgusting to look at and wonder about cleanliness of parts less visible.

Flight delay for mechanical. Inbound arrived on time. No one said why mechanical delay.

Forced to check bags. Crew uninterested in collecting trash. Unclean seats.

It was a train wreck but on an airplane. First off, flight was delayed then we board only to hear two announcements, First weather delays in Orlando and second backup battery warning on emergency lights. After sitting on the plane for almost 2 hours they have us deplane due to the maintenance issue. We were told they were getting another plane. In the mean time, I notice another American- Orlando flight and ask the gate agent if I can switch. He says he cant help me and I'd have to walk to A13 from A37. Really!? I get down there and get a seat only to get an announcement my original flight was RE-boarding. The Then inflight there's no communication and I notice on flightaware were circling over the Gulf of America. I call the flight attendant and of course she has no clue and apparently 5m later the pilot finally tells us about another delay. Why does American always have these service and delay issues? They are my LAST choice in flights now!

Flight boarded, departed and landed on time. Excellent service from flight attendant in FIRST

Flight to Tampa was delayed taking off due to plane arriving late but no other issues

We missed our flight and got stranded in Miami where we had to rent a hotel we could not afford. they would not work with us because they said it was weather related even though the gate attendant said it was not. I could go on but trying to get satisfaction has wore me down, which I believe is the intent. My only solution is to never fly AA again.

The flight was really crowded. Flight attendants were just ok.

We get stuck in the plane when landed during 45min and no communication from the crew People were listening to their phone and music out loud and nobody told them anything I definitely want stop booking spirit flight it is a disaster

First off, I had a conversation with a flight attendant that was working this flight. I overheard her telling another flight attendant while we were in line for Chic-Fil-A that the flight was not going to land until 12:47 pm. I found this odd since the flight was to take off at 1:03. I commented to the flight attendant that was going to mess up the on-time take-off She said. if you fly alot you will notice that it's a good thing if the flight even arrives at all. I said that was a low bar. I think that flight attendants represent their airlines whether on board or in the airport ordering food. I was surprised to hear such negativity. However, I have noticed that Spirit flight attendants are usually in a sour mood.. Eventually the flight arrived and I boarded and the flight took off an hour late. There was no direction about the on-board wi-fi. Nor was there any info in the seat back pocket. I don't know if there was wi-fi or not, There were no complimentary snacks or drinks for my row 36 as there was turbulence and the captain asked the flight attendants to stop serving just as they were close to my row. When the turbulence stopped, they did have time to serve us but they did not. Upon arriving, the flight attendant asked anyone not having to catch a flight to Ft. Laudersle which was a tight connection to sit down and let those people pass. I complied but I could not help thinking that if Spirit would have took off on time that they would not have to inconvenience their passengers. All in all, I think Spirit is a mediocre airline at best. There are so many things they could do to improve. Yet, since I only fly Spirit infrequently preferring Southwest and Delta, I like to see if they are improving and sadly no, they are not. One good thing - nice modern seats and interiors.

Went as planned. No wifi included and no screens. No free snacks. Didn't buy food so can't rate that. Unable to charge devices on plane. Staff were friendly and flight was fast, cheap and convenient.

I purchased extra legroom so I will be comfortable but the guy behind me is a big guy who keeps on moving and since he is big I can feel his movement at the back of my chair.

Spirit was on time. They maintained updates and information. The crew was friendly and professional. Because this is a budget friendly airline, they have dispensed with a lot of frills and part of that comes with a price, for example, the seats are not quite as comfortable as others. I am ok with a pay for beverage and snack service as I prefer my own anyway so this was not a concern. I thought overall, having a great flight crew and on time service was definitely worth losing some of the frills from other carriers.

Sadly there was a crew member very rude with my kid and with me.

They canceled the flight and didn't assist in getting a new flight on any airline. I had to spend 10 hrs in the airport after getting a ticket On Delta for twice as much. I've flown Spirit many times and this was my worst experience I've had.

Late taking off. ATC sent us circling around Chicago for almost an hour, after landing taxied for 40 minutes.

We had too many delays for the crew not the plane

Awful!!! Spirit cancelled my flight just 4 hours before departure- with no alternative flights available. I ended up missing a huge family gathering because I wasn’t able to get out. Such An awful experience. And on top of that, all the buckle and dime-ing for bags. I will never book with Spirit EVER

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 !!!!!!!

I am writing to express my disappointment with my recent Frontier Airlines flight. I was charged $99 at the gate because my bag was said to be too large, yet once onboard there was no available overhead bin space, and I was required to place the bag under the seat in front of me anyway. This made the charge feel unnecessary and unfair. Additionally, before the flight even took off, I was asked to move from the seat I paid for into a middle seat so another passenger and her cat could have my seat to themselves. I was not offered compensation or an explanation for being moved from a paid seat. Between the unexpected bag fee and being forced to give up my seat, this experience fell well below acceptable customer service standards. I would appreciate a review of this situation and appropriate compensation.

One of the worst travel experiences I've had. Had a flight scheduled with CVG to RSW on VLSWQX this morning departing at 5:30. Two individuals at the gate and one was in training. Not her fault but she didn't have the ability to check people in resulting in at least 15 families that didn't make it on the plane because they weren't checked into the system in time. When arriving at the airport to drop off our prepaid checked bags, the bag drop off agent asked if we could check our bags at the gate because of the long line. We said no problem so arrived at the gate by 5:00. They told those people that had previously paid for checked bags to stand off to the side while they let others that either didn't have a checked bag or their bag was already on the plan through. Realizing the gate workers had an issue, they either called for help or this lady showed up late for work as she didn't arrive until 5:15. The worker who had been there training the other individual and working diligently to make sure all passengers got on board. He even said that at one point all people that are currently in line are fine but asked the person in training to stand outside the ticketing area around 5:15 to notify any late travels that the flight was in boarding process and they arrrived too late. At that point, we're sill standing off to the side with our pre-paid checked bags patiently waiting. When the new lady arrived she couldn't have been more rude. It was an awful seen. Essentially they had asked for those without an assigned seat to board last, those with pre-paid checked bag stand off to the site and any traveling with a larger items that needed to be checked at the gate (such as a stroller), wait on the side. They realized that the flight needed to leave on time so the gate attendant shut the gate. So anyone without a seat assignment, those that had pre-checked bags, and the worst one I saw was a mother with two infant children was in line with use because she was asked to stand to the side because her stroller. When they shut the door to the plan they told her she could no longer get on. Her checked bags were already on the plane with her car keys in them, and the lady told her we couldn't accept anyone else on because the door was shut. She didn't even have a way to get home from the airport. Truely evil behavior. I've flown Frontier enough to know customer service is not a top priority in the company's mission, but this was an all-time low. I'm sending this after an 18 hour drive that our family just completed to Bonita Springs . I felt really bad for the lady being trained and the other individual trying to help, but when the new lady came to the gate she was truly one of the rudest individuals I've ever met. One lady had been there since 4am but because she didn't have an assigned seat they wouldn't let her on the plan.

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

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.

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

We were delayed three times ,and that destroyed my plans, and reservations
