Requested an aisle seat at the gate and got it. The staff so friendly

Requested an aisle seat at the gate and got it. The staff so friendly

My experience was very good. Everything was excellent except for the food. The food was mediocre. Not alot of options and the flavor was okay.

Flight was very delayed so I was able to get on an earlier flight via stand-by. Crew communicated effectively around delay and worked to make customers comfortable. Wifi was ok, streaming TV was great. App functionality broke down once I was moved to stand-by on earlier flight.

Sat in the tarmac at O’Hare for 65 minutes. This is a regular occurrence for delta at O’Hare

Delta was fine though my flight was delayed 4 hours into LGA and my return into ORD involved a taxi of 1+ hour to the gate

It was as good as it could be. Flying is not a pleasant experience these days.

The plane was very warm the entire time, despite my vents being open. Additionally, we didn't have internet on our personal devices

There was an unruly family behind us that made the short flight miserable!!! The cabin crew did nothing to contain it.

Flight delay was frustrating, also you cannot checkin online without delta app, web browser check-in throw errors

Three adults, three children. They did not give us seats together. Two seats together, in row 23, one in 13, one in 14, one in 10, and one in 17. When we got on the plane, the crew tried to ask people to move but basically threw up their hands. One person moved so we had two pairs of seats together. The 1.5 year old sat on a parent's lap (despite having paid for his own seat).

Flight was delayed multiple times with very little communication to the passengers waiting.

Inability to pay with points for my checked bag was very inconvenient and I was misleqd to believe it could be done at the kiosk but this was not the case.

At my original departure Istanbul I was told my seat and flight was cancelled from the 3rd party. I had no seat to get to my other flights .. they charged me $481 USD to board the flight that I already paid for

Good, the flight from Miami to Mexico City was better than Mexico City to Miami

Flight was on time, good service, but there was no free WiFi, even for first class passengers

My flight was delayed, then I got transferred to a new flight that was also delayed- which wasn’t Aeromexico’s fault, it was because of weather conditions. Most of the crew was very nice and patient, except for one or two flight attendants who were rude. The entertainment wasn’t on, so all the screens were off.

the guy in front of me put his seat back immediately...and then left it back including thru landing and taxiing to the runway. attendants did not check/ask him to put it up for landing.

Boarding - It is unclear where the line for the group are given the signs. A solution would be a diagonal arrow pointing to the lane in which the lane for boarding of a given zone should form. As it is now, you are guessing which side of the pole the "zone 3" sign is telling you to form the line. Inflight Entertainment - The Spanish subtitles function didn't work for movie watching (in fact, all subtitles didn't work), so was difficult to follow along and I watched the movie in silence without words.

An hour-long wait to check in, 90 minutes for luggage to come out, lost luggage, chaotic operations

No everybody brings the proper equipment to enjoy the plane entertainment. Then I was not able to enjoy it.

They miss placed a piece of luggage. My kids booster seat. How am I supposed to drive home with no booster seat?

Painless trip. Only downside: No entertainment system (which we know with Viva & Volaris) and very small seat space. I'm petite and felt squizzed. I'm not sure how most overweight passengers do.

They closed the gate over 25 minutes before departure and I didn’t get to board.

I paid for Viva play and most of the time didn’t work and also I order some drinks and the price was to expensive.

Everything was okay, but boarding begins late and when I was returning there was a gate change. The app never showed the change.

NOTHING.. THEY CANCEL MY FLIGHT WITHOUT NOTICE AND ENDED UP BUYING A NEW ONE..

Ridiculous fees for seats and restrictions of 10kg carry on. Cheap a$$ airline

Viva aerobús didn’t let me check in to my flight even when there was more than an hour before take off.

We had to pay extra for our seats and when we got to our seats a family was already seated in them. The flight attendant just told us to sit somewhere else. What would make it better would be a refund for the seats we were not given.

Great flight with a great crew. So cheap and yet so wonderfully fulfilling. Wish other airlines were this comfortable and well run.

Hate it. They do not provide any food or drinks during the flight, unless you pay. They also charge a ton of money to bring a carry on bag. And their customer service is the worst. I will never fly with them again.

Unfortunately it was not a good flight got canceled had to be at the airport all night long to get a different flight to another airport my first flight with Volaris was very bad. Poor services

In Mexico charges too much for my luggage and I ask for help and nothing one lady she just disappeared 😡😡😡😡😡never going to fly there

Better communication about delayed flight. I am thankful for a small credit for late flight.

Terrible. And they charged over $400 just for luggage. And threatened that I would loose my flight if I didn’t pay. So I didn’t have another choice but to pay.

The flight was delayed an hour and a half, and they would not update the board on when the flight was supposed to take off. Once the plane arrived, they started the boarding process before the plane was even ready for the passengers so we had to wait another 45 minutes on the tarmac while we waited for the plane to be ready for us. In my opinion, there is no point in starting the boarding process when you are not ready to board the plane. This just causes a crowded gate with everyone from zone one and zone two standing up going nowhere.

My experience was good. But it seems that every time I go on Volaris the plane is always full, not sure if because the price is cheaper. And the flight attendants kept hitting my shoulder every time they walked by the aisle with their food cart. I’m 6’4” so I barely fit in the seat next to the aisle. Plus the seat was defective. I had a hard time raising the lever where I rest my left arm. I tried calling the flight attendant 3 times if she could assist me but she was too busy talking in the back with her fellow flight attendants. Finally after 20 mins she looked my way and she too struggled to fix the problem but she finally raised it so I could get out of my seat.

When you make the 3 Lines to board de airplane , I believe that you should make only one line first and then call the next and then last ,,, because the number 3 wait to long just standing there ,, my opinion !!!

Flight got canceled, made me lose my connection flight to Japan. Someone has to pay for it. It might be you guys

I didn’t like anything, they were the worst airline I ever used, charged 40 dollars if you flight as USA citizen, if you want food you have to pay for it, seats are uncomfortable service is the worst

Maximizing profits is one way to a healthy bottom line, the other is repeat business and referrals from satisfied customers. Frontier has clearly chosen the former. One of many examples: Family emergency required me to cut trip short. Headed to the airport to fly standby for the return trip I had already paid for (yes I understand prices vary with demand etc). Was told there is no standby and that I would need to pay for, despite what it's called by the company, what amounts to a new ticket. And surprise surprise, there turned out to be dozens of empty seats on that flight. To say nothing of the sleazy third and fourth party resellers, the flight/ticket insurance I elected and thought I had paid for that mysteriously wasn't there when I needed it before I left, and on and on with third world sleazy management decisions. The inflight coffee (that I had to pay for) was very good though.

Flight was scheduled at 9:40pm. Got delayed to 10 am, the next day. crazy

The bag check, flight check-in, and onboard experience convinced my wife and me that we will actively go out of our way to avoid flying Frontier Airlines in the future. At bag check, we were informed that check-in could only be completed via the Frontier mobile app. Unfortunately, the app was extremely frustrating—sending us through repetitive, confusing loops that repeatedly forced us to decline add-on services with nearly every click. While most airline apps upsell, this one felt intentionally exhausting. As the process dragged on, we became genuinely concerned that my phone battery would die before check-in could be completed. We approached the bag check staff—who were standing together talking—and explained both our frustration and our predicament. They laughed. Later, my wife described the interaction as “gaslighting,” which felt accurate. We were then informed it would cost $25 per person simply to have our boarding passes printed. From that point forward, the tone of the experience was consistently hostile. The bag check employees were condescending and combative, behaving more like bullies than customer service staff. Unfortunately, that same attitude continued onboard. One flight attendant argued with me when I attempted to stow my backpack in the overhead bin. I explained that we had each paid $75 to check our bags specifically so we would not need to use carry-on space and could have adequate legroom. She demanded to see my ticket, pointed out that it said “no carry-on”—which I acknowledged—and I reiterated that this was precisely why we paid to check our bags. Her response was, “I don’t make the rules.” She then walked away, but not before asking if I “truly wanted to fly back to Chicago today?”—an unnecessary and unmistakable threat. It is also worth noting that despite booking our tickets together in the same transaction, we were not seated together. Upon our return to Chicago—where we could once again sit together—we compared onboard experiences. We both remarked on how unhappy the flight attendants appeared and how each of us was separately asked whether we would like to purchase a beverage. We declined. At no point was water mentioned as an option, leaving us with the clear impression that even water came at a cost—or that complimentary water, if available at all, was deliberately left unmentioned. Overall, the experience was shocking and deeply disappointing, but it was also a profound learning experience—one we will not forget and will not repeat. -Steve

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.

This company socks. It's fraud. They canceled our flight yesterday, and today we were late because of a really long line at the check in bag. At the rebook station, there was ton of people. The workers were all rude. I am gonna make a report to FTC.

The single worst check in experience I could imagine. I’ll never do any business with Frontier or any affiliated company

Too many extra fees, uncomfortable, little leg room. Will not recommend this airline.

Severe turbulence. Captain never came on to reassure passengers after things settled down.

We were delayed three times ,and that destroyed my plans, and reservations

The crew was delayed because they came on another flight that was delayed due to weather 10pm flight left at 1.30 am The airline made no effort to align alternate crew
