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.

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.

Everything was really good but the seats are not very comfortable.

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

I had no legroom, although I paid for extra legroom. I could barely put my bag in front of my feet and under the seat. The Wi-Fi was horrible. In fact the flight attendant said that they had to reboot it and see if it was going to work and never did.

The guy with severe body odor sat next to me. For the whole duration of the flight it was a torture. The airline should have better policy on limiting people with bad body odor to board the flight. Passengers should not be the ones to endure bad odor for the whole duration of the flight. The airline should be e the one to ensure decent air quality for ever passenger.

Overall it was a miserable experience... I will never fly spirit for more than a 3 hour flight or overnight.

The boarding attendant was slightly rude when I asked about checking our stroller. Made me feel like I was bothering her.

My wife and I are both handicapped and at boarding they upgraded us to a seat closer to the front rather than all the way towards the back. Much appreciated.

Not much seat room, but that was unexpected. But the seat headrest was very uncomfortable.

First the good, everyone was friendly and efficient. Flight was smooth and plane was very clean and new. Now the bad, seats have almost no padding on your behind. I was in exit row so I had tons of leg room for a 6' 2" bean pole with long legs. Everything was extra - water, soda, snacks everything besides oxygen. Ya get what you pay for, and my flight was cheap as you could ever want it, so no worries.

Not good 😐 Over priced baggage fees Small hard seats No wifi or entertainment options 😕

Didn't like anything!! Horrible flight. Small seating area and hard seats. Butt was sore after 2 hour flight to Seattle No entertainment or free refreshments No wifi or USB charging receptacles to charge phone entoute like other airliners Luggage rates were 3 times as much as competitors. Difficult to navigate online luggue process to pre pay before flight Overall bad experience WILL NEVER RIDE OR RECOMMEND FRONTIER TO FRIENDS OR FAMILY MEMBERS!!! THIS IS A SHAME!! MOST MESERIBLE FLIGHT OF MY LIFE!! AND I THOUGHT SPIRIT WAS 👎 YOU GOT THEM BEAD HANDS DOWN!!

Flight was a little late taking off. Seats are too upright, no ports to charge devices, no wifi, no entertainment

Six hour delay. Poor customer service. No voucher. Bad communication. Missed important appointments.

Our flight was delayed an hour, then when we got to board our flight finally, we were waiting in our seats for take off for 45 minutes before it was communicated that there was a maintenance issue therefore we waited on the plane for over an hour while that was resolved. We did not get to Phoenix until almost 3 hours after we were originally supposed to. This was the first and last time I will be flying Frontier.

Flight was canceled with little warning. Flight was rebooked through Ontario, California and connecting flight was delayed by over three hours. Frontier is living up to their Greyhound of the skies reputation for sure.

I purchased a carry on bag online…was supposed to cost $72 but after a whole slew of bs charges, the total was over $175.00. Because of these hidden charges, I will not even consider flying Frontier ever again. It’s just not worth the hassle. I’m scratching this company off my list forever.

Flight was OK. Seats were good no cell phone charges on the plane no TVs or entertainment.

There were 3 leg for the trip and each leg was delayed by 90 minutes or more. The boarding process takes forever with people waiting on the jetway even though most folks do not have carry-on. The whole process is poorly managed.

Flight cancelled and was told by a rude gate agent that they don’t accommodate on other airlines. Had to wait 5 hours for a connecting flight that had a 7 hour layover. Would not allow bags to be checked early so we couldn’t go through security .Had to rent a car for the afternoon to store bags and get a meal. Also incurred a hotel fee. No apology or reason given for the cancellation- just rudeness.
