Southwest is Southwest. No frills. If you're luck enough to get a happy crew (we did), then it makes for a nicer flight.

Southwest is Southwest. No frills. If you're luck enough to get a happy crew (we did), then it makes for a nicer flight.

Southwest is typically delayed, and it gets wearisome. It is no longer a discount airline and you get way less than you pay for when it comes to comfort and Ce.

We sat on the plane on the tarmac for 4 hours.

I'm not a fan of Southwest's model. I don't like the herding style of boarding.

It is southwest seat was ok. Not the most comfortable seat

Plz don't take away free bags and free seating

Excellent! Only question is how we check in at exactly 24 hours in advance and end up at the end of the B boarding group

It was 2 hours 45 minutes late, for no apparently clear reason.

It went well. Plane wasn't full. Will be great when assigned seating is in place

Excellent experience. WiFi worked on this leg of My trip

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.

The flight itself was fine, but the boarding process was extremely frustrating. There is no one scanning boarding passes - passengers just scan themselves and enter the jetway. By the time my husband and I got on the plane and were halfway to our seats they determined there were too many bags on the plane and everything at that point needed to be checked. This created a lot of unnecessary chaos. They should have alerted people before getting on the plane that they would need to start checking bags instead of waiting until people were already on the plane.

The best flight I’ve had in a while. The plane was like 25% capacity, if that. Smoothest boarding and deplaning process I’ve ever experienced. Wish all flights were this smooth.

Traveling with JetBlue from NYC was convenient as accessing JFK airport was straightforward via the LIRR to the AirTrain. Maneuvering through the terminal was hassle-free, which was a pleasant start to the journey. However, the flight experience itself left much to be desired. The seating arrangement was notably uncomfortable; despite securing a window seat, space felt cramped. This was exacerbated by the middle seat passenger encroaching on my area, which made the flight less enjoyable. Additionally, while the in-flight entertainment system initially seemed like a reprieve, the sound outlet on my seat was inoperable. This issue turned what could have been a manageable three-hour flight into a rather tedious ordeal, as I was unable to use the entertainment system effectively. While JetBlue provided a smooth process in terms of airport logistics, the on-board experience highlighted areas in need of improvement, particularly in terms of comfort and entertainment system maintenance.

The flight crew that we had in our section may have been tired or something. I asked the flight attendant about my son’s screen not working and she spoke down to me like I was stupid. He still had no working screen throughout his flight. The other members had no personality and seemed like they were annoyed when you asked them for something. Definitely took a hit for simple things on my JB experience.

Over 2 hour delay for a 50-minute flight is unacceptable, especially in normal weather. Very poor communication via app

Didn't like size of seats. Found charges for checked luggage and carry on too high

Great! We boarded on time! Everything went so smoothly! The flight was so smooth

Prepaid for 1 bag but my prior airline did not provide it to me in time to check it with Spirit and I could not get my $75 refunded.

Plane delayed which seems to be the norm with spirt. Everything is an up charge. I had to pay an additional fee because I was late getting back to my car. Will never fly spirit again

It was horrible. We were not allowed on the flight by spirit staff at the gate during boarding because I had a guitar. The same guitar I had at check in which I paid for and they said I can take it on the plane. We missed our flight, lost our luggage, and had to pay another $900 to rebook flights. Worst travel experience ever and spirit staff are the worst staff ever.

My experience with spirit was terrible. Customer service was terrible. Flight got canceled abruptly with no accommodations made for the inconvenience or any sort of help. I was unable to rebook a new flight.

The flight attendant spilled ice all down my leg and all over my suede boots and didn’t even apologize or anything. They just gave me a look like “what?!” Incredibly rude and dismissive. I saw them roll their eyes at other guests and even once yell at a lady with a baby.

It’s what we expected from Spirit..reasonable cost, good for a 2-3 hour flight. Disappointed that we had a 2 hour delay in departure from DFW for a maintenance issue, but the pilot handled it well once we were outbound on a different Airbus.

My experience was okay. The flight did not offer even water without a fee. Also had to pay extra for my carry on, as I was told I had to check my bag, even though it said I had the option to carry on a bag when booking. This costed me an extra $100. Would likely not fly with Spirit again.

The flight was rescheduled several times without a reason for the schedule changes. I had to be in New Orleans at a certain time and it was just easier to drive at a certain point. I don’t know if the flight ever left. This is my first experience with Spirit Airlines and is also the last.

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!

It was a no frills flight. Would have liked to be able to charge my device

Seats were extremely uncomfortable and it was very hot on the plane.

Since they are a budget airline, I wasn’t expecting too much but they did some things well. They were on time, the plane was clean, boarding was fairly straightforward and the staff was cheerful and friendly. The only downside was comfort. The seats were fairly hard and after a 2 hour flight your rear end is not feeling so great. Maybe a little more cushion in the seats, Frontier!

Check in at Philadelphia international was absolutely terrible! I fly 2 to 3 times a month and avoid frontier at all cost and will never fly Frontier again! The night before travel, I tried checking in however, the app was giving me an error, so I went to the desktop, which instructed you that you need to use the app. The next day I presented at the check-in gate after trying at least a half dozen times prior to getting into the airport and continuing to getting the error in the app. I actually had rebooted my phone numerous times and reinstall the app just in case. My phone is only one generation older than the current model. It has no problems completing a frontier flight purchase or any other app issues. There was only three frontier employees working at check-in and a huge line while I was in line I continued to try and check in via the app. As I approach the desk, I was dreading dealing with the agent. He was extremely unprofessional, anti-semantic & very ignorant, and mean to the people in front of me, as well as the people who ended up being behind me. He literally told people “Man I don’t care bout y’all” in his native dialect! Maintaining my composure I approached and explained the situation. To which he replied, you’re gonna have to pay then! I don’t understand. It’s an issue with their app not allowing me to check in! Not my issue! He told me if I pay cash it would be $15, $25 if I pay credit card. I don’t understand a $10 difference for paying with a credit card? I am completely cashless so I continued to try using the app to avoid the $25 fee, Which I still don’t believe that I should be responsible for since it was Frontier’s technical issue!!! I continued to check in via the app a couple more times after he verified I was doing everything right he proceeded to continue to belittle the people behind me. Yelling at them saying I don’t care about you people! I cannot believe that this is the way that businesses would treat its customers! Unfortunately, the black mail with dreadlocks did not have a name tag all he had was a frontier sweater on! For the $25 fee that I ended up getting charged on my credit card. I should’ve just booked originally with Spirit or any other carrier! I have no problem paying fees that I should be responsible for, but when it’s due to a technical failure of a company, the customer should not be responsible for it! I cannot believe that it’s not frontier going out of business!

they delayed my flight which ended up, causing my layover flight to leave without me, resulting in me missing a flight and having to stay overnight in Houston international. I got no compensation other than a flight to my original location only a day later. i’ve never experienced such a unprofessional situation
