Pros: "seat space was great and I was lucky enough to have medium size passenger next to me :-)"
Cons: "Can't really think of anything . . . my expectations were exceeded"

Wifi wasn’t working well so we couldn't view any media.

Food service was bare-bone. Better bot to have any at all rather than hand out premade coffees and cookies to random few passengers.

Crew was great. Friendly, calm, interesting, happy to be there. That makes a huge difference. Plane was very quiet. Also quite empty so I had three seats to sleep across

Had assistance at airport getting from arrivals gate to departure gate; I couldn't have managed without that extra help. Thank you Delta.

They charge me for the luggage which is was included on the ticket

More space in the cabin. The guy in front of me leaned his seat back and I felt he was sitting in my lap.

Was a great smooth flight from Detroit to San Diego.

When we checked in my friend and I were sitting seperate. By the time we got to boarding, they automatically switched our seats. I really liked that.

Late flight, always blaming the flight crew, stale almonds, pushy people. Why don’t they have the people sitting in the back board first? So much easier getting through an empty plane! Duh!!

As we lined up to board they gave our plane to a flight going to Newark. So then we got delayed until they could find another plane. Flight crew was ok. I’m assuming since it’s a shorter flight they only offered water and coffee.

They didn’t let me get my boarding pass through the app because I have a lap infant. The ticket said to see a gate agent but there was no gate agent available. I was supposed to go to the kiosk. Ended up missing my flight and they said that I never checked in to my flight so there was nothing that could be done. I will never fly spirit again. Not even worth the hassle and poor customer service.

Cancelled my flight , currently stuck in Houston and will likely miss my cruise

Didn’t happen. They stranded us in Orlando and had to book a flight on frontier to get to our destination.

Flight left very close to original projected time. Paid for checked bag weight overage (my fault). Plane was literally brand new & this was its 2nd flight. Seats were alittle uncomfortable (I'm 5'11 * 175lbs and was alittle cramped, & brand new seats had little cushion). Food options were good. Main thing was flight took off & landed on time.

I particularly did not have no problem with my backpack, but a few people in front of me did. The chairs were really uncomfortable. Unless is a super short flight for over a weekend I wouldn't take this airline.

Do I need to call them or will you handle my complaint ? I paid for one carry-on bag. my email said up to 50 pounds when I got to the counter they charged me $79 more for my 48 pound bag!!! they said nope only 40 pounds. My email says 50 pounds. !!! I’m out another $79!!!

Passengers play their phones so everyone can hear them. No one tells them to use earbuds. Very annoying and unenjoyable.

I liked how we boarded early to combat all the chaos from people bringing oversized personal item luggage. It's so painful watching the process and feeling overwhelmed by the process.

Spirit Airlines has the worst customer service. I don't advise flying with them.

I checked a bag because it was $5 less than carry on. They managed to lose my bag on a 2.5 hr direct flight! Frontier has no airport staff at baggage claim to help. As soon as I got home around 11 pm I tried to use their online system to file the claim for lost bag - system wouldn't take the # on my baggage claim ticket - said it was not the correct number. Also said that I had not checked a bag, which wasn't true - even my online boarding pass showed that I had checked a bag. Wasted about an hour on that process with no luck. Tried again in the morning - same thing. So tried online chat with Frontier bot - waited 35-40" twice to be connected to a baggage agent and it never happened. Eventually drove to PDX after work and waited 2 hrs for the Frontier ticket agents to arrive prior to the next Frontier flight out of PDX and FINALLY got some help from one of them, to take me to lost luggage area where I was able to retrive my bag. Probably took 4-5 hrs. of my time and endless frustration to get my bag. This was my first -- and LAST -- experience flying Frontier Airlines. Check-in was also extremely difficult and time consuming. The flight itself (and staff) were fine but everything else about the experience was a total disaster! The fact that Frontier literally has NO WAY to connect to a human voice for customer service (in this case for lost luggage) is the WORST!!!!!

Frontier is a crappy airline nothing about it is honest

I didn't get to do this flight l, hard to review

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.
