On time take off…US cabins look tired and need of refresh!

Backpack should NOT allowed put in the flight bin , only put it under the seat. I can't find space put my carry on luggage!!! and I pay for it ! that was very bad experience

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

Terrible! The plane was old and you are required to connect your own device to their Wi-Fi rather than have entertainment options in the back of the seat in front of you. The Wi-Fi went out during the flight and there was only one plug for the devices every two seats. Three out of five surrounding my family did not work. The seats and spaces under them were so small I could not fit my backpack, which I’ve always brought on flights and fit before no problem. The crew were unpleasant and patronizing.

Due to one crew member not showing up to work, our flight was significantly delayed causing us to miss our connecting flight in Houston to Mississippi causing us to be delayed by more than 6 hours and missing our event all together. Very disappointing. All because ONE crew member called in sick. United did grant us a $15 meal voucher, which was a small but appreciated concession that I wasn’t able to use because I ordered my lunch and paid for it before applying the concession, and the staff said it was too late to use it. Ugh! We also had a TWO delay coming back from Mississippi, but that was on American Airlines and it was due to weather, so not their fault. Anyway, not at all impressed with United’s handling of our flight and the HUGE disappointment of missing our important family event for our 90 year old mother. All that money and all that stress and emotions for nothing. Having to wait the hour to bring an employee from LAX seemed like something that should not have happened. Why don’t you have a local back-up? Santa Ana is not a little airport in a rural area.

Hated every minute of it. This flight should have only taken 1.5hrs but was delayed over 10hours. Now I am being told I cannot be compensated or refunded my ticket price or extra leg room, which I purchased but did not receive, because the airline is throwing the blame on the 3rd party I purchased tickets through and 3rd party putting the blame on airline. No one wants to help. They received their money and that's all they care about. Im going on 3 days of still trying to get to my final destination, had to cancel car rental, car insurance and hotel. Currently staying in airport until hotels open up. Thank you Lufthansa, Kayak, Underpricer and United for making this trip the worst ever.

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Awful. I got stuck next to a person carrying a dog and behind someone with a dog. People need to board these dogs downstairs. The cabin is crowded enough with your pets

Flight was 1/2 hour delayed leaving Phoenix. Otherwise it was an average flight. Flight crew on this trip was very nice.

Horrible - they lied to me about baggage & boarding, even though I specifically spoke to their agents the day before my flight about my issue. When I showed up they did not let me board and stranded me at my airport until I bought a new flight with money I did not have to spend.

Not sure why JAL partnered with American Airlines because their service is no where near similar. Flight attendants were not friendly and didn’t smile. Food was horrible…

The experience was great and much better than the flight going out. of course I was in first class but the service was excellent

Comfort of seats, ease of boarding. Food selection could be better

Food options were limited which is absolutely embarrassing for a Flight of this size The staff did not come around as much and I am not accustomed to such poor service from American Airlines Drinks I believe were limited to soda and water

Crew were attentive and friendly. Flight was smooth and early! I enjoyed the less crowded plane. Thank you!

We are gluten free, there were not any available complimentary gluten free options.

No meal on a cross country flight? SFO-MiA is pretty much the definition of a coast to coast flight. No meal provided. Sky high wi-fi rates too. Stop nickel and diming your customers.

The staff was unprofessional and didn’t communicate very well. The boarding process was very disheveled, potentially due to a power outage the previous day but there was no contingency plan to properly get passengers boarded the following day. Once boarded the aircraft stayed on the tarmac for over 45 minutes due to high winds. The communication was sporadic but an announcement was finally made an additional 30 minutes later that the flight was cancelled but we couldn’t get off the plane. Prior to deplaning one of the gate agents came on the plane and made an announcement for everyone to pickup their checked bags and take a card to rebook a new reservation because they didn’t have adequate staff. Flights were missed, passengers went to different airports and there was little to no assistance from AA.

They need to have enough immigration forms for every one. They should offer free water to everyone, unless some one needs bottled water

Delayed 6 hours! finally able to board, then had to wait 45 minutes for the plane to fill up. Mid flight when food service started, they had nothing to offer with the exception of chips and cookies. Worst flight ever!

The priority seat are great especially the first row! Crew was very cordial and helpful, airplane efficient, the departure and arrival was on time.

I had a flight before this one and I was able to get to the plane, the doors were open and they didn’t let me in. It was still 15 min before departure and the plane was there with the doors open and the hall as well and I went all the way there and they didn’t let me in. Then they tried selling me another flight 4 times more expensive than what the original cost and with a 7 hour layover in a different state when my flight was direct and cheaper. Very disappointed, specially with their 0 flexibility when it comes to travelers with multiple connections.

They not allowed to bord flight, arguing that was cancelled the flight reservation. No chance to find and explain answers, very bad treated by Airline staff… At the end we buying a flight ticket with Aeromexico. Is a low Price Flight Company (cheap), as it is cheap treatment for customers… seme with Kiwi .com app. With we did our reservation. with KAYAK.com never get this kind of treatment.

Buen servicio y muy puntual El problema ENORME es pagar por la página de Viva Aerobús lo cual es imposible aún con fondos suficientes en la tarjeta. Eso te obliga a acudir al callcenter de la aerolínea, en donde para que te atiendan transcurren 45 minutos, y ya que se tiene la suerte de comenzar la llamada, te toma otros 60 minutos terminar el proceso de pago de los tickets o de la maleta extra que deseas comprar.

It is ridiculous that electronic checkin for under age kids can be done and need to be done over the counter. Having said so, we were requested to do the single line for this as if we never did any checkin or made services for this to happen fast. Just ridiculous. Flight delayed as it is the regular business for this airline.

an absolute joke. couldn’t even board because they sold our tickets out from underneath us. we had tickets in hand with assigned seats and they still denied boarding at the gate. i’m sure you guys won’t follow up or do anything so merry christmas.

Flight was on time Flight attendants should be kind and empathetic

Viva continues to strive for the worst airline experience ever.

Overall good flight. The flight attendants were annoying and unfriendly. They would ask me to grab someone else’s trash can just waiting until the person woke up or after the flight is done. It’s not my job to pick up someone else’s trash. Especially when it’s not easily reachable.

The WiFi tv wasn’t working. The flight was over sold and moved several times. The gate assignment appeared on the screens right as we were supposed to board. Because of the flight being over sold we were almost stuck in Cancun for a couple of a days. The flight attendants were unfriendly and would wake you up to pick up other people’s trash.

The reason we chose Volaris to fly from LAX to Mazatlan, Mexico was because of the DATES and TIMES for the NON-STOP flights. When those flights got Totally Changed that was UNACCEPTABLE ! ! ! Also, when my husband Died unexpectedly, the Only statement that Customer Service kept repeating was "they would only offer Credit on a future flight". REALLY?! Volaris was only going to offer CREDIT on another flight to a DEAD PERSON ! ! !

Service of the person who gave us the boarding pass

Overall good but we had a minor scare when a wind shear caused the plane to re take off on the first landing attempt. The crew handled it well and we landed safely on the second attempt

It was unfortunate that I paid more than $120 one way to carry on my luggage to only have to have them checked baggage. We board the flight and there’s a lot of overhead space. They checked our bags in Group 2 but Group 3 was able to board with their luggage. I would not fly Volaris again. The flight attendance on the plane was very nice but the employees at the gate prior to boarding was very rude.

For the price, you pretty much can't beat this airlines. As far as comfort, you could do a lot better, but it'll cost you. Over all cheapest way to get from point A to point B.

To many extra fees, poor customer service and very uncomfortable flight. No leg room and seat wont recline.

I am disabled and was unable to get any assistance from Volaris. I had to wait in line at front desk for 45 minutes, I am by myself, and unable to stand. When I got to front desk check in, they had no assistance for me. I did however, have wheelchair assistance when I arrived in Mexico City. Thank God for that!

It was horrible, our flight back was overbooked and had to take a flight 12hours later in the day but to LAX. Volaris is horrible.

I had a terrible experience with Frontier. I arrived before the 60 minute cut off and was told that Frontier has a two hour window for bags. I was then told the next available flight wasn’t until the end of the day (I had booked a 6am flight). I took a look around and saw other people being told that they could not board their flights or that they had to pay additional fees. I opted to rebook on American Airlines. There’s absolutely no straightforward way to contact Frontier, so this ticket was a complete waste of money. Oh - and the kicker is that the lady lied about the two hour cut off.

Frontier won’t help you at the airport without paying $25. Carry on was $75. Then you get on the plain and every beverage or snack is also a charge. Seats are hard and real packed in. I would never fly them again.

Worst experience I have seen. The flight was cancelled without any reason.

My experience with frontier staff at the Denver airport was absolutely horrible. The manager on duty was even worst if was the worst experience I have ever had, I have never been treated so poorly as a customer in my life! The staff was extremely rude, eye rolls and attitude and then refusal to help me at all. I wish I could never fly frontier again that’s how horrible it was!

The Frontier app wasn’t working. So I could not pay for a carry on the week prior to flying. They charged me 99$ at the gate to carry on a duffle bag.

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.

There were 3 leg for the trip and each leg was delayed by 90 minutes or more. The boarding process takes forever with people waiting on the jetway even though most folks do not have carry-on. The whole process is poorly managed.

They cancelled the flight then did nothing to help us rebook. It was awful - I won’t fly with them again

The process of buying the ticket and navigating all the hidden charges that Frontier throws at you was a terrible experience. The actual airport experience and flying was fine.

The truck that was refueling the plane drove away with the hose still connected to the plane and ripped part of the plane off with it
