Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

The 1st class male crew member was very pleasant - the short female with round glasses , maybe in 50’s had no personality- never spoke when delivering my food, drink, & never smiled the whole trip! In fact looked annoyed when the boarding proses was happening- I would never hire this woman - unfriendly . Have never dealt with a crew member like her-

Absolutely nothing flight was cancelled and delayed for 2 days. Barely a heads up I want a full refund

Best airline! Always friendly and welcoming. Skyclub was great and loved the fast free wifi on board. I also love that you can pre-order your meal on the app!

The boarding was horrible. You couldn’t hear the announcements at all. Probably because there is so much in the area for businesses. They need a louder PA system. Other than that it was a good Delta experience.

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I liked the ease of checking in, luggage check in, wheel chair assistance, boarding and flight.

The main person that was coordinating everything was a short white/light skin Spanish man and he was very rude. It honestly made me feel like it was everyone’s First day at work. His announcements were very not reasonable and they did not make sense. The stewardess on the flight that made the announcements she didn’t even know what she was talking about she sounded inebriated. There were no snacks or drinks on our flight there wasn’t even much turbulence. This flight was not enjoyable nor was it what a Delta flight should be and just this past week I flew with Delta 3 times.

Terrible. Delta delays caused us to miss our flight and they did nothing to fix it.

We were told that our flight would be delayed for 90+ minutes because of weather, so we went to get something to eat only to have them randomly start boarding 15 minutes after the announcement, with no warning.

Entertainment... No earphones passed out. Many including me couldn't use the TV. Legroom was good. Crew was indifferent and a bit surly. Free wifi was a nice convenience. Check in desk location was unknown. Gate number on the boarding passes was wrong.

Confusing. Delay updates were out of whack At one point it said my flight was 25 hours. Three gate changes and two delays only to change back to original departure time. Gate announcer and on board flight attendant (Alejandro) making the announcements was impossible to understand due to accent and speed of speech. After beverage service the rear flight attendants sat back there on their phones. No refills no checking in, one sweep through for trash collection. Very impersonal. Bring back Coke products

Business class is great. New airplane, very comfortable, better than some of the major airlines I am used to

Delayed by almost an hour - I also noticed that all JetBlue flights departing from PBI were delayed yet the weather was perfect.

I loved the wifi, much better than Delta. Seats were old. and bathrooms dingy.

There was no wheelchair or wheelchair escort at the gate..unacceptable

Delayed 4 hours because of maintenance issue they knew about all day. Get another plane. Time is precious!

I liked that boarding and take off were timely despite a 15 minute delay due to weather. The pilot communicated with us the entire flight keeping us informed re: turbulance and slight delays on the runway after we landed.

Has been always great except flight cancelation in the past at very last minute waiting till 2am and we when have to beg for overnight accommodation

Delayed so that missed connecting flight. Connecting flight was also delayed on the tarmac but they closed the gate before the rescheduled time.

Took off over an hour late with multiple mechanical issues. Gate agent in Dallas was lazy and was slow as molasses. Had a line 10 people long. Spirit bad..

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

The Flight attendant had an attitude and didn't allow anyone any time to prepare for landing despite being absent throughout the entire trip

Horrible people at the gate, they force me to check in my carry on, even thought no one behind me has to do it. I had to get out of the airport in NY to get my bag and go thru security again on my way to Honk Kong. The worst part is the employee threatened me with loosing the flights if don’t comply.

Delayed abs delayed Gate crew giving poor info - we are definitely leaving at —- Ultimately to cancel flight after 4+ hours of delays Just cancel it earlier

Delayed flight, few announcements with information, no comps, cluster f boarding because zones weren’t spread out and announced loud and repeatedly, staff did their job -nothing more nothing less, annoying kids were speaking and kicking the heck out of the back of my seat and parents weren’t willing to parent… so another typical day of air travel in the US.,

Flight was delayed until Next day as crew timed out

The flight was great until towards the end when the flight attendant read an excessively long commercial for purchasing an american airlines credit card. The worst part is that we are doing a lot of traveling this year so i was actually interested in getting the credit card, but I was so annoyed with the long commercial that I completely dismissed the flight attendant bringing around the information. Next time, keep the sales pitch to 10 seconds and then pass around the brochures!!

I was able to get on standby with relative ease

The whole day was a nightmare. Flight extremely late. Boarding was a mess of a nightmare.

Never been on this flight as i had missed it due to delayed connecting flight

Missed our departing flight due to poor baggage drop staff. At the airport with 2 & 1/2 hours to spare and waited in bag check in until 15 minutes prior to gates closing before baggage staff asked us to move to the front of the line. We weren’t the only passengers that missed the flight. Poor organizational operations by Spirit staff. Otherwise , the return trip was fine.

Worst airline experience ever. Lost my IPad going thru security. Charged for my dog carriage at the gate not at ticket counter. Gave away my seat 6D. Expressed I wanted my seat back after charging me 99 for dog carriage. Should have thrown it out. Had a 16 yr old Yorkie heading to Boston after being a snowbird. Seats small. Very bad experience. Still don’t have my IPad. Horrible

The boarding gate was moved so many times that I missed my flight. No attendants would help me. The wrong gate was even on my boarding pass. I had to repurchase everything. I’ll never fly again. Really a terrible day as I had planned to see a former student who is dying in Louisville Never ever will I forget that day. Your airline is totally uncaring.

Hated it I would not use Kayak or Spirit ever again.

Flight delayed then canceled! I will NEVER fly Spirit Airlines again and will tell all my friends!

Flight kept delayed from morning to late afternoon so I had to make other arrangements

The crew was not great or professional. It seemed like they didn't really want to be there. A true lack of effort for accommodating customers.

I paid for WiFi, but it (WiFi) was very very slow, will never take again! Impossible open Utube 😤😤😤

Good for the price. My only complaint is that the pilot should keep the air flowing while passengers are waiting to getting out of airplane.

I arrived 1 hour prior to boarding, and they said I was too late for a domestic flight. First time I heard that :-(

Frontier is a crappy airline nothing about it is honest

Crew members are very rude and not cooperate with passengers.

30 minute delay due to boarding and settling of a family.

I am HIGHLY unhappy with the amount of money I spent on the flight. Paid in advance only to find the flight at a discount price a week or so before the flight. I will not fly frontier again and have bad mouthed your business since to anyone I have spoken with about flying (which has been many a people). Crew was mediocre and instead of moving me to a spot where I could gain some leg room they sat their flight attendant there. Won’t be flying frontier in the future.

Well, I didn’t have food! So NA wasn’t an option. I’ll be back!

First time flying with Frontier . From buying tickets ,getting boarding pass and boarding plane was super easy. Definitely would fly again with Frontier .

Our flight was on time and unremarkable which I'm grateful for, as it is not the norm traveling these days. Frontier is a low-cost carrier and it really shows when compared to other "normal" carriers. They don't even give you water during the flight. The coach seats are decent, however it was not as clean as it should be. We had crumbs all over the floor by our seats.

They lost my baggage on my connection flight, it’s been 24 hours since I put my claim in and still no update on my bags.
