I prefer spirit over all other airlines! Yes, you have to pay for everything à la carte but I believe it is worth it. The staff and crew are friendly! I avoid frontier at all cost!

Contour was a great choice for Plattsburgh. Much easier than flying to Burlington and taking the ferry across the lake.

Frontier's add-on fees for personal items is outrageous.
JeremyFlew with Sun Country AirPHL-MSPJun 2024
Don’t fly Sun Country. Not worth the savings.
Verified travelerFlew with Alaska AirlinesPHL-SEAApr 2024
No US airlines have any easy boarding, comfortable planes, decent food offerings, ambiance, etc like they used to. Suggestions: take off baggage fees, start serving real food offerings ( not a snack item), treat all people on board as paying customers instead of just 1st class or premier seating. In other words, all US airlines need to step up their game!

United seem to have the best track record of actually getting you to your destination as scheduled.

8.0 ExcellentAnonymous, Apr 2025LAX - DEN

Delta flight was on time, seats were comfortable, and crew was nice.

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

Terrible and im avoiding them in the future. My initial flight was delayed causing me to rebook my flight and when speaking with the representative to rebook I explained this is the second time my flights were delayed and they did nothing to help me. I wasn't booked to comfort plus or given a voucher or anything. I was almost late for my meeting that I needed to attend on Monday because of the games delta played delaying my flights even more and putting me in the very back of the plane next to an extremely intoxicated passenger

Flights on time. .Ride was as comfortable as can be expected in steerage. Luggage arrived at destination. Attendants were fairly friendly.

Multiple delays and not straight answer from the United team

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

Electric plugs didn't work. Entertainment system wasn't working

The design of the light switch on the arm rest is ridiculous.

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

leg space better than expected. two washrooms for one plane isn't enough.

The gate attendant let me walk right by her with a bag too big for the overhead compartment

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

Everyone was nice. It was on time and the food was. Airplane food, but not horrible

One bottle of water and a package of cookies for comfort plus. We had to literally beg a flight attendant for an extra bottle of water later in the flight due to feeling dehydrated.

late again! but its my only option to not take 9 hours to get to Memphis

Almost everything was outstanding. First, we boarded on time and the flight crew did a great job getting everyone seated. Then the pilots took their time and care to make sure the plane was full de-iced three times as there was a bad ice storm a few hours earlier. The plane ride was smooth and comfortable and even the economy seats had decent room and comfort. Flight Attendant Lisa went above and beyond to make sure I was comfortable - she is outstanding. The only thing wrong with the flight, and it is something which needs to be addressed, is that the gate to gate time was over 6.5 hours and not one meal was served. The only thing offered to eat were two small cookies for a transcontinental flight - unacceptable. Charge me more but give me a meal for a long flight. Thankfully Lisa found something for me.

Very poor. Our special services attendant gave us incorrect information. I also was mishandled at landing. There was no wheelchair waiting. I fell deboarding the plane. Appalling!

I had a very unpleasant encounter with one man from customer service: he was extremely rude and miserable. And his condition was reflected on his decision to send me to the worst airport hotel and get an awful flight connection. My hotel shuttle had never arrived and I had to book another hotel. People served by other representatives got a much better treatment and deal.

The flight left a bit late, but arrived close to time expected…With the flight being close to full the crew did well serving drinks to all in a very timely fashion. The flight was a pleasure…

They didn't have any gluten-free snacks, oddly, which I require...or any flavored soda water or decaf tea options, which seems to be standard.

My flight back my reservations were list because they said I didn't pay my pet fee when I had a receipt

They could have done a better job announcing the boarding groups and asked for more drinks (water) if needed.

terrible service, no room for a dog underfoot, a broken chair that is impossible to sit on and all this costs a lot of money

Easy boarding. Met expectations for a 2-3 hour flight. Early arrival at DFW caused a 39 minute delay on the tarmac in getting to our gate. 😏 overall, good flight.

Very efficient process and boarding, seats felt standard. Flight conditions from take off to landing had been very smooth. Alcohol on the menu however was not available… Will fly Spirit in the future for the price, you can’t really complain if you fly light.

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.

Worst airline ever! The guy weighing my bag had his foot on the metal plate and when I called him out on it, I got this stupid little smirk. La is a scam and so is Spirit Airlines. All the flight attendants looked like they hated our flight just as much as we did.

My experience with Spirit went pretty much as expected. It's a no frills airline, and you get what you pay for. I don't require much, so I was grateful to have an inexpensive way to travel. It is sad to me that the gate agents and flight crew don't smile much or seem very friendly or helpful. They are competent and efficient, and that's really all I need.

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.

It was fast but uncomfortable seats. Had to pay a bit extra not sure why? Maybe in selection of all my 4 tix together ? Just knew I had a balance before getting boarding pass online when departing from satx ? And flight was delayed..

In a word, it was horrible. The flight crew timed out and this, apparently was not accounted for by management. This meant that our 10:15 departure turned into a 1:30am departure the next DAY!!! And some brainchild decided to email us 12$ food vouchers set to expire the 9th, but they sent them after EVERY VENDOR WAS CLOSED in the Miami airport and obviously none would be open in New Orleans. I found this to be another sterling example of, at best, shitty management…at worst an absolute lack of empathy for your customers.

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

The seats were hard molded plastic covered in plastic vinyl. And the scam to charge people extra to sit together. Don’t they know we can just ask someone to trade seats. And watching the staff separate young children from parents… super classy. We had to guilt them into offering up our seats. This companies policies suck. Don’t give them your money.

The seats were awful, hard plastic covered in sheet vinyl. The airline tries to scam you into paying extra to get seat together when the flight wasn’t full. They were going to separate a family with young children but my wife who had a row to herself gave up her seat so the young mom could be with her young boys. I’m never giving this airline my money again.

It was a short flight so no food or entertainment….

Seats are uncomfortable but price is good. Guess I can put up with misery for four hours.

I’ve never traveled on Frontier before. If you want basic, no frills, friendly service at great prices then give them a fly!

Cancelled and declined to find alternatives Earlier flight is 2 days later Sent the cancellation notification very late, wish I knew earlier would have stayed to watch the Miami open final game Very disappointing service

The worst flight of my life. Never will I fly frontier again

Landing in terminal 2, but my luggage is terminal 3. We (and others) were looking for it in terminal 1. We probably missed the crew broadcast, but the communication could have been clearer for non native (or elderly) passengers.

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