Round trip flight to Canada and back to the US was smooth and efficient.

Round trip flight to Canada and back to the US was smooth and efficient.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

Spanish speaker flight attendants were incredibly rude. A male flight attendant named Allen, grabbed my bag out of the overhead bin and moved it without my permission. When I asked what he was doing, he informed me that the overhead bins were public space? It would be easy to ignore this comment, as you don’t know the whole story, but the flight attendants were militant and rude. Delta, you can do better!

In ATL they have two sets of departure screens. Follow what is on your airline's departure board - the ATL Airport Authority departure board had completely incorrect details about the gate assignment for my flight, which would have made me miss boarding.

Flight was delayed it was hot while sitting on the plane, one engine was working on the plane until they had to do some jimmy rigging down the runway in order for the other engine to charge up. It was ridiculous

The flight was very good and the staff was very friendly and helpful!

The only thing I would say is we tried to get on a standby earlier flight, but with our fair we couldn’t. That seems senseless to leave with open seats..

Very easy to use and convenient, you can perform any action within the same portal

In a world of delays, Delta was on time both ways! Boarding was fast and efficient. Staff was friendly. AND wifi worked.

My business class seat was inoperable and unable to recline for 10 hour flight.

All went very well. We used the AIFI Airport, such a lovely facility. Definitely needs better transportation options to get there.

Both ground crew and flight crew were rude, and did not provide any level of service. They made it very difficult as we were traveling with a passenger the required assistance.

From the check-in, to the flight, and arriving, everything went very smoothly. Unfortunately, when I received my baggage it was severely damaged. I have a hard shelled suitcase and it was completely smashed it. I’m not sure how this could happened but I am extremely disappointed that my belongings were damaged beyond repair and continued use.

Really nice, all good, nice crew and all on time

Unfortunately I had an awful boarding experience. Our first flight with Aeromexico was fine and landed on time however it couldn’t find a gate and we were late which made us lose our connecting flight with Aeromexico. The staff handled it horribly when we explained our situation and would not led us board when we missed the boarding time by a couple minutes. The staff were extremely rude and did not attempt to even help us. Because of this incident, my husband and I missed a full day of work which negatively impacted our salary which we need. Please compensate us for the work that we missed.

It was OK. The flight is pretty long for the airlines to only offer a simple sandwich on business class. The entertainment is similar to that on other Skyteam members. Ultimately the airline lost my bag and didn’t deliver it to me until the next day after a lengthy lost baggage report.

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

Aeroméxico cancelled my ticket without advice AND It make a last minute mess in my intinerary, no solving my situation, bad advice and bad customer service

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

It was good in general. The Crew during the flight were very nice at all times.

It was cancelled at the last moment and the customer services seemed unnoticed to this change and hanged me off the phone the first time I called.

Staff especially Alan Hernandez was a great help with arrangements for my partner and me sit together. This made the trip do much more enjoyable. Thanks so much.

One of the flight was delayed an hour. We then boarded a new flight. We were told to unboard after some other time. To wait for the next flight for another hour. I paid for a short flight that turned in to half a day of travel.

No entertainment, charging, nor wifi on board but I napped for basically the entire time so it was alright. Was allowed to switch seats because the flight was not full but everyone was assigned to the back. Comfortable seats and we got moved to the emergency exit so the extra room was nice.

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.

I was charge $90 for my bag more then the fight crazy!! And the plain hit a couple of birds on the take off bird strikes we returned back and had to change planes bad customer service everyone has an attitude problem!!! Bad experience!!!

The bad thing is they didnt send me the deatils about how much alowed bagage ehight 1 carryon or cheacking bag Also they just send in spanishlanfuage i couldnt understand emails

The boarding process was ridiculous. The boarded groups into a walkway just before the aerobridge (about 20 mins late), whilst we watch the crew stroll casually onto the plane, running late. And then they made us line up on then aerobridge with no aircon for 10 minutes before we boarded. Staff are just as ghetto as the customers. Wouldn’t fly again

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

No empathy for my situation, arriving at the check-in counter 5 minutes after the deadline to deposit baggage due to a very delayed incoming intercontinental flight. The attendant simply stared past my shoulder and picked up the microphone to announce a "reminder that all passengers must arrive at least one hour before the flight" before speaking to the passenger behind me. I understand that there are rules above deadlines but at least show some damn empathy. It was Christmas morning and I'd been travelling for 20 hours for goodness sake!

The flights were on time, the ground crew and on board crews were kind and efficient. The free snacks for Premium+ were good, similar to US First Class snacks. The plane were clean and bright! Complaints? The seats were worn and the seat-back pockets were missing. Overall, I'll book again with Volaris. Ignore the negative social media posts, understand what your fare includes, buy the add ons you need. We had no problems with our personal items and carryons.

It’s a 2 1/2 hour flight so good and comfort was not my real concern. Safety, easy, fast was what I was looking for. The crews were great, plane was clean, boarding from CBX was fantastic! Definitely traveling this way again.

The money you save flying volaris is not worth it

Is was a good short flight with some turbulence! I would fly Volaris again.

We had boarding passes for the next flight but we could not catch the flight in the small airport just because volaris closed the boarding at the counters an hour before for which we had to sepnd almost 3+ hours to catch next flight. There are hardly anyone who can speak english, but thank God, we have found an young man who could not only speak English but helped us book for the next flight. The air crafts are noisy and scary sometimes to hear that squeeking noises during the take off and during the flight. They do not even offer a cup of coffee for free in flight. The prices are super high and the services are zero. That’s pretty much for this airlines in summary.

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

The boarding , and it would be nice if they would let us know head of time about flight changes

The flight was delayed by two hours. I had paid for extended leg room. Due to the delay, the plane was different and I didn't end up having extended leg room. I finally was able to reach Volaris on Whats App and they gave me an airline credit. I wanted a refund to the credit card since I hardly ever fly Volaris. Other than that, it was a very comfortable flight.

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

The check-in is either at a kiosk that didn’t allow me to check-in because my middle name was not on the reservation or at an agent that cost $15.

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

Plane was hot and miserable and the crew was rude!

12 hour delay required getting on and off plane 3 times - would have at least liked to have been offered a snack or drink

They didn’t offer a water, even after I asked

Zero issues with this flight. Crew was outstanding and flight was super. Plane was clean and fine. The seats need more padding and water should be provided without cost. I recognize it's Frontier but there are some things that should still be part of the flight. But still very satisfied with the experience and quality.

They switched our terminal 3 times and we were delayed for four plus hours!!!

It was an early flight and most people napped/slept and the crew let us which was nice.

The crew acted like they had never done this and kept barking passive aggressive orders at people. + the security line + the delay + sitting on the tarmac for 2 hours + none of the apps or signage updating with correct times

More inflight connection. And leg space is horrible. And the paying for baggage I'd ridiculous!!!

My flight was originally from SAT to MCO connecting from MCO to ORD. We got diverted to ATL and than Frontier staff there was sooo un helpful first they said they couldn’t give us any accommodation since our flight first got delayed that cancelled and now it’s 221am and I am still in ATL since they said they need to create a new flight my final destination is ORD and I have been delayed twice and cancelled. With no real help the frontier app didn’t work no email updates over all such a horrible experience
