I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

Good and consistent Printer in lounge did not work for me :(

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

Delayed in taking off because no flight crew. The in seat entertainment was working properly.

I upgraded to first class only to find out that I still had no access to the sky lounge without a sky miles card or AmEx (something that should be emphasized outside of the fine print!) Also, no food or drink service provided during the flight, so I basically paid 4x more just for “free” checked baggage and a bigger seat. Not worth it.

Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

Bottom seat cushion is almost non existent. Very uncomfortable seat.

Delta was great the entertainment was outdated. Screen was very small and didn’t work.

Plane still had screens for watching movies. Good selection too.

Flight crew was amazing! I don't like that the Polaris seats are side-by-side.

They need to improve their boarding process. Group 1 and/or paying first class passengers shouldn't be in the middle of boarding process

The plane was so gross and dirty. Literally saw dust layering and flowing out the grey vents. Dust was all over the air vent knobs to the point where I took my sani wipe and cleaned them down so at least it wasn't blowing my my face. Also, I upgraded and paid for Wifi and it's always so spotty. I get we are in the air, but don't charge for it if it's not going to work. I expect so much more from United. They really are giving up.

We had a 90 minute delay due to equipment failure that was detected just before we took off. United rebooked my connecting flight.

Short flying. The seats do not recline at all and very uncomfortable.

Flight was on time, crew were excellent. For some reason our originally selected seats were changed. We had to re-choose our seats when we checked in online and options were limited. One of our two checked bags we placed on the wrong carousel. It was only be shear luck that I saw it. That cost us 20 minutes of wasted time. So much for the “priority” tags. They are meaningless, and have been ever since they were implemented. I wish you would do the save some money and stop using them.

The flight attendant was very kind and offered my son a snack for free.

We fly to Ecuador frequently. Checking in is usually a hassle because most United agents take some time before they can verify that my passport doesn't require a visa to Ecuador. This time the process was even longer due to the cyber attack. But she was really nice to us. So glad we brought plenty of snacks to supplement the 3 flights from SEA to GYE.

Two hour flight delay, it was awful and loss of sleep.

The flight was as good as it gets when flying. On time departure and arrival plus no lost luggage.

Flight was cancelled as I was in line for security. Next available flight got me to my destination 24 hrs later than the first. No refunds offered, just credit toward another flight. I booked with delta, got to my destination only 2 hrs behind my original flight schedule. Won’t be using American again.

Checked in the minute I was allowed and still wound up in group 8 for boarding.

great experience. minimal lines at BWI. at DFW they got a long haul 787 boarded in 30 minutes

These are the things that AA did right on this flight:1 Smooth Boarding Process, 2 Departed on time, 3 Arrived early at destination 4, Friendly and courteous staff. Great job AA!

More room. International flight - by the time you put your purse and shoes under the seat in front of you, add in the pillow and blanket they give you- makes for tight fit.

Overall good. Tight connection in DFW because of gate unavailability upon landing.

Excellent customer service at check in at Austin flight to DFW and excellent customer service from Karren in terminal B at DFW.

The flight attendants were talking the entire time on the back and I couldn’t even take a nap. Super annoying

Had to wait a long time for wheelchair in Dallas

Flight was ok with exception of the multiple delays. As with all Spirit flights, the sights are extremely uncomfortable and lack leg space. However, the price savings is the plus.

Okay for the most part but Good boarding and on time

Paid extra for a “comfy seat” which was anything but!

Staying with Dallas 4 hour stay ...it's was torture sorry. .. about to say that

Quick flight. But crew was late so boarding was delayed. No food or entertainment as flight was an hour so no possible eating there…flight was also delayed but I think that was the fault of SAN airport not spirit…

Everything that was available was excellent. Spacious and comfortable, with lovely and helpful crew (one was having a bit of a sour day, but that happens). We sat on the tarmac for one hour and seven minutes waiting for our gate to clear in SAN, but the pilot kept us informed and, amazingly, was very professional in not ragging on the airport (whose fault it was).

Well, the seats were SO tiny. I’m five-foot ten-inches talk as a woman and thank god I wasn’t more than 150 pounds as I would not have fit at all. I understand there are the “big seats”for an upgrade or a blocked middle seat but I was not prepared for the size. Also, there was an incident on the plane with a man who wound up being escorted off the plane at landing by TSA… I understand this was not in the control of the flight crew BUT the flight attendants were arguing amongst themselves at the front of the plane and we could hear them. There was a flight attendant in her 50s scolding a male flight attendant for “placating the guy” that was causing a ruckus and telling him “you should have been on our side not his.” Not only was this unprofessional to do in front of passengers, but it caused anxiety in nearby people including myself. We don’t want to feel like there is a potential danger on the flight - 9/11 flashbacks. The flight crew should remain calm and I believe the male flight attendant was in the right in trying to calm the man who was an issue.

Comfortable and plenty of. Having to buy water and coffee, though is ridiculous!

Better overall experience from my first flight with Spirit several years ago. Efficient boarding (albeit I arrived after all rows were called) and flight actually left earlier than planned. I am still baffled by being charged for everything, even a non-alcoholic beverage. And there is definitely less seat room which makes a flight that’s more than 2 hours really uncomfortable.

The plane crew made the decision to leave a LARGE group of us passengers who were stuck literally at the gate next to the Las Vegas flight & trying to get off. We were lied to & told the Vegas to Dallas plane was going to wait for us. I’m having to fly the whole night to my destination now because of this

Booked direct in July '24. Turned into a 14 hr layover (both ways) in Denver. My 5 day vaca turned into a 1 day . Not good, BUT,... Thank you for the people @ Frontier who were professionally friendly & approachable.

Stop changing gates at sfo. When you are elderly going back for it’s not fun.

We understand and comply with Frontier’s bag sizes. We’ve had some problems in past while having to await other passengers who do not understand the baggage restrictions or have not prepaid and that is usually our biggest concern (others delaying us) with flying Frontier. Flying OUT of ONT, however, has always been a great experience. I’ve also noted even on delayed Frontier flights very knowledgeable pilots who manage expectations well.

There was no easy way to check in. I don't want to install an app to checkin. I will use alaska from now on because they have a web check in method that is easy.

The crew was ghetto lol I felt like I was on an inner city field trip

Horrible! The short distance flight ended up taking 5 hrs! There was a 3 hr delay for the flight to take off and there was a 70 min wait on the tarmac for some bogus reason that the pilot said the gate he was supposed to board was taken up. After a 30 min wait he said the plane that was supposed to push out of the gate called a medical emergency and 40 min later he ended up boarding another gate. For the initial 3 hr delay there was no information/alert about the gate or delay in the app or the boards up until the boarding time and even beyond! Had to walk all the way to the end of the terminal to find the frontier staff to ask what was going on. Avoid this airline at all costs! If you have carryon bags or checked bags , their prices come equivalent to the prices of more reliable airlines. They are the worst in timeliness at 60% (reported as delayed) this year (check the data) by a high margin even compared to the second worst airline. If you are ok with having a miserable flight experience with the odds close to flip of a coin, feel free to try them. If you value your time , money and flying experience, stay away.

There was nothing to like, flight delayed had to move to different departure areas, disorganized to say the leasr

Delayed for two hours due to trivial issues. No reimbursment. Also on arrival further delay due to terminal malfunction.

Our flight was canceled for no known reason. We weren’t told until we were checking in at 5:00 am. This was after our last flight with Frontier where we sat on the plane for three hours (not an exaggeration) before we took off because of a mechanical issue. We won’t be flying Frontier again.

Allowed me to chose my seat without extra charge (I purchased full-price ticket) and boarding was in group1. Didn't even serve water.
