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

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

Nothing they cancelled my connection and couldn't get me on a flight for 3 more days

First flight of the day… MINIMUM FUEL! 15 minute landing delay at HOU due to fog turned into a 2+ hour delay! Rather than circle, they had to divert to another city to refuel! Sat on tarmac at Austin to refuel. We ALL missed our connections! The crew, including pilots, were clueless. Crew was really a mess. At HOU, Untied employees were exceedingly rude to all. It was pitiful.

No lounge access with “United First” ticket. False alarm about late flight, jeopardizing connection. Wrong meal. Loose power socket would not hold plug, could not charge device. In-flight access to text messaging did not work. Toilet seat on plane would not stay up.

Crew were fine, drinks and snacks were as well but we were delayed for around 2 hrs which made our entry into Mexico delayed as well with the influx of arrivals at the same time. Sort of wasted our first day of vacation. We left Pittsburgh at 630am and did not arrive in Mexico until late dinner time.

Boarding was unorganized. They expected passengers to ask people to move their assigned seat they paid for in order to sit together. The seats even in comfort are smaller than other airlines and the flight attendants appeared not to be well prepared

Due to one crew member not showing up to work, our flight was significantly delayed causing us to miss our connecting flight in Houston to Mississippi causing us to be delayed by more than 6 hours and missing our event all together. Very disappointing. All because ONE crew member called in sick. United did grant us a $15 meal voucher, which was a small but appreciated concession that I wasn’t able to use because I ordered my lunch and paid for it before applying the concession, and the staff said it was too late to use it. Ugh! We also had a TWO delay coming back from Mississippi, but that was on American Airlines and it was due to weather, so not their fault. Anyway, not at all impressed with United’s handling of our flight and the HUGE disappointment of missing our important family event for our 90 year old mother. All that money and all that stress and emotions for nothing. Having to wait the hour to bring an employee from LAX seemed like something that should not have happened. Why don’t you have a local back-up? Santa Ana is not a little airport in a rural area.

The customer service was excellent! Check-in, baggage check-in, boarding, the flight went very smooth.

It was delayed several hours which delayed our connection in Denver. Not happy.

Ok, but comfort was lacking as the seats were way to small

Perfect flight. Efficient boarding, on time take off and early arrival. Generally smooth flight.

American is a steady for me. I always get what I expect from them. Sincere effort to get me from one place to another.

Awful. We had an 8 hour mechanical delay- no vouchers and no kind/courtesy/professional representatives in the entire airport. Not only was it a terrible experience for both my 7 year old and myself, I still have not heard back from American about how they’re going to correct it- I’ve sent 2 or 3 emails about our experience- which was just awful. Not to mention according to national traveling laws, we should be reimbursed… but of course they’re not responding.

BAD. As a family could not sit together. The gate agent told us there was only one seat in the middle left, when we got on the plane the situation was very different with whole rows of seats empty

Plane was delayed an hour causing me to miss my flight to London and now I am not arriving until Sunday instead of Friday. I am stranded at airport and they give me $12 of food vouchers. It's a joke and everyone I talked to was rude

The Airline was not prepared for weather delays. We were held up due to an incoming flight being delayed and so we did not have a flight crew. This caused an extra delay for departure by 2 hours.

The plane was freezing cold. Normally I’m fine on planes but I needed to toss a sweatshirt on this time.

I missed this flight due to delays on my previous flight.

My husband and I pre-ordered our food, but they did not have my husband’s order, and my cheese plate was very average. I asked for a blanket and was told they don’t carry blankets on domestic routs. The flight was on time and smooth!

Good flights. Departure and arrivals were on time. DFW was a little problematic in that the Skytrain without prior notice bypassed the Echo terminal so that delayed my arrival at my connecting flight.

There was no water offered to passengers during a four hour flight, five hours on the plane. There is no entertainment on board. The crew interrupt everyone often to sell credit cards and reward packages. Other than that, pretty typical flight. You get what you pay for.

Someone opened my checked bag and stold75 euros Not happy

Terrible experience, will definitely NEVER fly with Spirit again (this was my first AND last time). They canceled the flight JUST minutes before we were about to board, with no warning, no reason, and no recourse. We managed to get on a different, much more expensive one-way flight home (with United) later that night, and arrived early the next morning, although by that point, the garage with our car had already closed for the day. So we were left having to pay an exorbitant $200 Uber ride to get home. Trying to fly with Spirit is definitely “penny wise and pound foolish,” absolutely NOT worth whatever meager savings they promise (and then still nickel and dime you for everything from water to a carry-on bag).

Three out of four legs of my trip were delayed. The last leg of my trip was delayed due to passengers and crew not being ready to take off. The boarding process started way late with no explanation as to why. The flight attendants did not have the passengers in check for takeoff - folks were walking around, trying to change seats, and causing a general disturbance preventing us from departing and the crew did nothing about it. All of this caused us to miss my connection home due to the first flight landing at the same time the second one was due to take off. The entire Spirit crew (except for one flight attendant) was unapologetic and unpleasant about this. No one apologized, no one showed any inkling of empathy whatsoever. The response was basically, "we booked you on the next available flight". That next flight was a full 24 hours later, we would have been stranded in the airport and no one even cared or acknowledged us as customers. I'm disappointed in the lack of compassion shown by Spirit agents and customer service reps as a whole. It felt like we were a burden due to airline scheduling issues. The one flight attendant (did not catch her name, but from (ORD to FLL) was wonderful and empathetic.

Poor response to delay, getting on plane, off plane and back on again

My flight was uncomfortable and crammed. There were no pockets to store things, I couldn’t move my seat back slightly. Beverages including soda cost extra. My husband flew on another spirit airline flight, which was delayed a total of 48 hours, only to be canceled.

The plane was not on time for boarding or departure or arrivals.

Flight expected to leave at 6:40 pm ended leaving at 8:00 am the following day. I slept in a cold airport. Never again Spirit for me…

This was the return leg of my journey with Spirit Airlines. Despite its reputation, I found no issues as it got me from point A to B safely and without delay, especially with no mechanical delays, which is fantastic in my book! The staff, from ground crew to cabin crew, were all pleasant and hassle-free. The flight was smooth from takeoff to landing. I have absolutely no complaints about this no-frills airline!

It was the worst ever, i will be filing a lawsuit to get a refund. Our flight was delayed 4 hours so we would miss our connecting flight, we were not rebooked to our destination the same day, we were not offered any options to get home on the same day despite being clear that we absolutely cannot get stranded at night due to family, we were forced to book our own flights on a different airline to get home, and spririt is refusing a refund because our flight wasn't cancelled, only delayed. oh yeah, and they lost our luggage on the first part of the trip and you cannot get a hold of customer service when anything goes wrong, on hold for 30+ minutes. and their app breaks so you can't use that either.

Better than expected.on time. Friendly staff in NY however MYR not so nice.

The flight crew and flight attendants are poorly trained and demonstrate poor professionalism. They have a sloppy appearance and communicate with patrons poorly. It is embarrassing for them to be representatives of an airline and for them to be called professionals.

After 5 hours of delay, they cancelled the flight. Very disappointed

My flight to LA was cancelled. I waited at the airport for 3 hrs saying it was delayed and then all of a sudden it was cancelled. Frontier only gave me a voucher and refund but could not rebook me. Flights on other airlines were too expensive last minute. I had to drive down to LA and didn’t even take my return flight home since I had to drive. One of the worst airline experiences in my life. It’s crazy how airlines can just upend people’s plans just like that.

Very delayed with little to no communication from the captain or flight crew. All announcements made were not audibly understood by passengers. Very poor communication. After arrival it took approximately 20 minutes to get a jet bridge to the plane.

Flying Frontiier was extremely poor!! I paid for a7:15am flight on flight 1601 from PHL To Las Vegas and the delay was brutally, excruciatingly and disgustingly long (8 hrs). I arrived by Uber to PHL at 5:30 am and had to spend the entire 8 hr delay inside the airport. Even more atrocious was that the flight was delayed twice. On the phone with customer service for two hours and was not fully compensated. I feel taken advantage of with this airline. They offered a menial couched for another flight within 90 days to me and my husband who has never flown but this experience has made us almost 100% sure to not fly this airline and will suggest that others don’t either. We don’t want to book ever again, don’t want a menial voucher and I believe by standard and because the flight was delayed for 8 hours, I should be fully reimbursed for the entire round trip. There is no excuse why this should have ever occurred. After sharing my experience with others in Vegas and Philadelphia, I was told that Frontier airlines is notorious for long delayed flights, poor customer service and refusal to compensate people correctly. I’m very nervous to see what departing from Vegas to Philadelphia will bring.

I fly Frontier often and generally don't have any issues. For some reason, the Denver to Houston's George Bush Intercontinental (IAH) flight always needs to wait on the tarmac in Houston because a gate is not available after landing. I've been stuck for as little as 15 minutes and as much as a little over an hour. I know only fly the Frontier Denver to IAH route when there is not an available flight to Houston Hobby (HOU).

Flight was 3 hours late leaving. Poor communication from the staff about delays. Impossible to get in touch with customer service (by design). And it actually didn't come out to be much cheaper than a non-budget airline! Not worth the headache, I'm never flying Frontier again

I’ve never flown frontier without a flight getting canceled. I understand that things go wrong with planes, but all other airlines handle cancellations so well. Frontier becomes a dumpster fire if a problem appears for them.

Checking in was easy and simple, crew was nice and efficient, but I would improve seat assignment randomness to make it easier to sit together based on when you check in. Overall would fly with them again.
