10 hour delay with minimal updates. Couldn’t leave terminal and then ended up on redeye with a dirty broken plane. It is literally impossible to reach customer service via gate agent, app, phone, text or email.

10 hour delay with minimal updates. Couldn’t leave terminal and then ended up on redeye with a dirty broken plane. It is literally impossible to reach customer service via gate agent, app, phone, text or email.

I thought that I had pre-purchased carry-on luggage and was surprised when I tried to check in that I did not have it.

Flight departure was 90 min delayed, and the boarding experience was confused, stressful, and generally poor. Additionally, the wifi on the plane was malfunctioning for all but the final 15 min of the flight into ILM.

Great experience and In love flying in and out of Provo airport

You get what you pay for. It’s like a bus but flying. No frills, no snacks. Leg room was fine, boarding was good.

Overall good. Plenty of legroom and fairly comfortable seats. No issues with capacity and the overhead been even though most people brought several carry-ons on. I don’t think Breeze really enforces the pay for a carry-on rule.

Surprised at how much I enjoyed Breeze. Paid for the Nicer upgrade which made it closer in price to a flag ship carrier but with more comfortable seats and much more leg room. Crew was polite and since we brought our food no loss there. Would make the point that the ‘have to pay for a carry-on is BS’. Most people did not and had several. Still was plenty of room in the overheads.

Comfortable seating, adequate space available, nice to have USB port, polite crew.

My experience is typically great with Breeze. This trip wasn’t any different.

This was my first experience with Breeze. The plane was cleaner and more comfortable than any other I've experienced. The process of boarding was streamlined. We boarded early and arrived at our destination 45 minutes early. The only hiccup was my ticket was rejected by TSA PreCheck and I got sent to the back of a very long line at Fort Myers. I entered my information when I bought my ticket, but it apparently didn't connect to my permanent profile. I'll correct that for next time. I was expecting an Allegiant experience, but Breeze was much more upscale. I really, really enjoyed it.

All good except once again bags took an hour at Midway Airport Happens all the time. Ridiculous

Everything went smoothly and we even arrived a little bit early.

Great vacation. Can't wait till next year for another one.

Great flight but super high price. Glad it was a business trip and not personal

On time. Friendly staff. Took to long to pre bord all the specialty groups. Cramped small plane

The seats were comfortable, and the boarding process was pretty smooth.

3 hour delay. Had to change plans and was still delayed.

The staff was very friendly, professional, and courteous. The overall flight was a great experience.

The crew canceled the complementary snack and drink in anticipation of turbulence that never materialized. I was counting on the drink (water) to take the the doses of medication - prescribed for my heart condition - that were due during the flight. Since no snack or meal was served on this flight, I cannot rate the food quality. Otherwise, this flight was excellent.

Departure was delayed more than 1/2 hour while we waited for luggage (only) transfer from another flight/plane. Once approved for takeoff, the flight was excellent.

Very well recently! Frontier is improving and less harrassing customer on luggages! Positive!

Good for a budget airline! It was easy to get on, staff was really nice. Can’t say anything about the food or entertainment because it wasn’t available, which is fine.

I am writing to express my disappointment with my recent Frontier Airlines flight. I was charged $99 at the gate because my bag was said to be too large, yet once onboard there was no available overhead bin space, and I was required to place the bag under the seat in front of me anyway. This made the charge feel unnecessary and unfair. Additionally, before the flight even took off, I was asked to move from the seat I paid for into a middle seat so another passenger and her cat could have my seat to themselves. I was not offered compensation or an explanation for being moved from a paid seat. Between the unexpected bag fee and being forced to give up my seat, this experience fell well below acceptable customer service standards. I would appreciate a review of this situation and appropriate compensation.

It was costly and difficult to check in. $85 to take a small suitcase with me, carry on or checked and $75 on the return trip, Plus $25 if I didn't check my self in check in $25, because I couldn't do it on the kiosk. Small very uncomfortable seats, waited on the runway for near an hour each way. It was my worst flight to date.

It was ok. It was expensive to check 2 bags ($75.00 per bag), and then it took a long time to wait for shuttle to take us from one terminal to the terminal where the plane was taking off at LAX. And all of this for a flight where we had to pay for any food or drink that was not water.

It didn’t happen. I booked it and then was told it wasn’t available and then forced to pay far higher prices for a worse option

A 630departure flight Delayed 6hours! They changed my gate, I moved to the new gate. Had our flight on the screen for 12noon departure. I go get above to eat, check screen again and the flight was gone, no notice no announcement, nothing!! They sent my bag on the flight I wasn’t on, got it back to me 3days later. Thank goodness they did refund my money but I will NEVER fly them again.

Due to weather, my flight was delayed, further delayed, then canceled. I eventually got through to a support person who helped me find a different route out of MSP, but to get to DIA, they didn't want to, but eventually did help with the connection ticket purchase. But even this replacement flight was delayed time and time again, and I would have missed my connecting flights and I didn't want to get stuck in a layover city, so after 12 hours at the airport with two young boys who were very tired, we just cancelled our plans and spent the week at home, instead of Nana's.

Plane and crew on board were fine. Everything else was terrible.

The third party booking with cheapflightsfares was awful. Kayak should NOT partner with them. They sold me a bundle including seat selection and carry-on, but did not book the carry-ons with Frontier, so I’m out of pocket for $414 more while I await resolution.
