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.
