Red eye from San Diego. Temperature of the cabin was way too warm and the air duct flowed very little air.

Red eye from San Diego. Temperature of the cabin was way too warm and the air duct flowed very little air.

Great job Southwest! My family doesn't fly often but we felt safe the whole time.

Comfortable. Easy. No problems. Just wish they had gf options for snacks.

The charges were ridiculous for an hour flight and the turbulence was very scary.

The seats are now more narrow. I paid for front row the seats in the front are even more narrow than before.

The boarding and seat assignment system no longer works for me, but I know it is being replaced. Otherwise, I am good with the overall experience.

San Diego airport is brand new, spacious, airy and very smooth checkin at SW baggage drop.

No trays in our seats, we sat in first row, purchased a business class fare. Had to hold our drinks and snack in our hands. No plugs for our cell phones. Had to pay for it a drink cocktail each. Seats so uncomfortable.

There was over a 9 hour delay for one thing after another. A toilet problem, they had to change the brakes, they had to refuel, three pilots times out, etc. We had to sit on the plane at the gate for over 5 hours with no air.

Unfortunately it was not a good experience. There was a rude stewardess.

Service was professional and quick. Premium economy seat was comfortable given the class

The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future

Over 2.5 hour maintenance delay on first morning flight with no acknowledgement, compensation or even gesture of good will. Aircraft had overnighted at airport so issue should have been addressed prior to boarding. Over 3.5 hours before first slow and deliberate beverage service.

No seat back entertainment. And app had a hard time getting entertainment loaded.

Complimentary light meal would be appreciated. But great flight crew service on all legs

The food was terrible this time. Otherwise pleasant, quiet, on-time.

It was great with United overall except for two things. 1) It was a 5-hour flight and we were with kids, so we were asking for extra snacks. They were extremely reticent to dole them out even though there wasn't any meal and the kids were starting to hit their limit towards the end. 2) Baggage didn't arrive until 80 minutes after we landed.

Staff was rude. Didn’t give water for 2 hours. Worst service

We took off an hour late due to arrival airport not having enough gates. That was followed by 1:30 wait to get our bags delivered for the entire flight.

It’s a service to take you from one point to another. No frills. You want it, you take it. It’s upon you to bring food, reading material, games to play, movies to watch, etc. The wifi onboard never works - so you cannot even listen to any podcasts, music, or get updated news feeds. The toilet is a mess, and a four flight does not need any hygienic interventions when people either splatter their pee all over the seats or on the floor. It’s a monopolized service and so smile and bear it.

Broke my luggage and I can't get a resolution yet.

There were no TV screens - even in Business class. 5 delays, and only given $12 meal voucher! Terrible!

Flight was delayed again and again ultimately almost three hours getting us to our location at close to midnight by the time we got in and out of airport to destination. I had taken time off work to enjoy an evening at destination and that was now wasted

No food/snack served during the flight. Crew wasn’t interested at all. Flew American First but flying low cost with Ryanair is even better

The flight was good. The only reason I did not say “excellent” was the delay

They could have done a better job announcing the boarding groups and asked for more drinks (water) if needed.

Ac was broken so we deplaned, waited 2 hours, taxiing for takeoff they said the plane would not fly so we went back to the gate and got a new plane which took another hour. In all a 4 hour delay for an 80 min flight.

We were delayed bc ground crew gave the flight crew the wrong paperwork. We taxiied to the runway then back to the gate to get the correct paperwork that no one bothered reviewing the first time we pushed back. Boarding was rude and stressful like it always is. Gate agents and flight attendants are all over 55 years of age, embittered by years of underpayment From AA leading to their passive agressive bitchiness for no reason.

Boarding time was easy & quick. Crew was excellent. In-flight entertainment was great/easy. Seats are too small and not enough room between rows: felt like a sardine/very cramped.

Ground crew forced me to double pay for infant international charges, when I complained about this and told them, with proof, I already paid they threaten to not allow me on the plane because I was “being rude”. Horrible ground management, horrible airline.

Super BAD Everyone Behind the counters in Cancun Not Helpful At All And then on the second flight I Had to purchase Cancun - Guadalajara one of the flight Attendants Kick Out a Couple Out of the Plane and that Flight Attendant Had a Mask So People wouldn’t take pics of her and she was kind of Mean ! I Would NEVER Flight VIVA EVER THEY ARE NOT FRIENDLY AT ALL ! People think They Are Cheap but They Arent!!!

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.

THE AIRLINE FUCKEN SUCKS... NO DAMN PROFESIONALS.. NO CURTESY THEY CANCEL THE DAMN FLIGHT AS ITS ABOUT TO TAKE OFF

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

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.

They cancel the fly and don’t give a money refund.

The air conditioner was poor and we were delayed 1 hour for no apparent reasons and no information provided

We had an awful experience getting our bags checked in. Frontier’s check in on the app manipulated us into buying the business package because that was the only option available for a checked bag which included two checked bags per person which we did not need. Upon arriving to the airport, we stood in line for what seemed like forever at the baggage check in and there was no one available at the counter. We were first in line and we were afraid we were going to miss our flight due to the baggage attendant being late. After realizing there were a lot of other people waiting at the baggage check in and no one available. I reached out to Frontier and could not get any customer service so I had to call the airport to page the baggage attendant to send someone to the counter to check in our bags before we were able to go through security , I finally spoke to the attendant at the counter and explained to her that we had to pay for two checked bags person a total of six bags when we only had a total of three bags between three people she said to reach out to Frontier and they would issue a refund for the three bags that we paid for and did not need. I reached out to Frontier which I was not able to reach anybody by phone so I had to go through their automated chat feature, which sent me around in circles until I finally reached a representative to assist me. I explained to them what happened and they explained that they were not able to assist me. I continued to push the issue with them as this was very frustrating and they finally put in a customer service ticket where we were issued a flight credit and we were so disappointed because after this experience, we NEVER want to fly Frontier again, and we do not want a credit that we will not use. Frontier charged us almost $500 for us to check three bags which is absolutely absurd! The customer service agents were not able to offer anything else other than a flight credit and I do not feel like my frustrations were truly heard , we will never use Frontier Airlines again ! Truly Theft by Manipulation! They should be ashamed!

Every day about it was very different all the boarding pass where all wrong l miss flight no refund all crazy

The trip was good but the last minute changes I didn’t like because I had already talked to the attendee and they didn’t help me with my ticket I was having trouble checking in and when the time was up they help me but charge me for that and last minute luggage it was a small bag. After I was in the airplane I realized you were charging because the flight was almost empty and you have to get the money some how. Thanks for everything.

Our flight was delayed by four hours without notice, the app for getting my boarding pass is super confusing, and I wasn’t able to check a suitcase without paying for a higher cost package

First the gate was a total nightmare-no chairs anywhere! So over crowded and only one bathroom and nightmare of food service - took forever and NOT one place to sit. No inflight entertainment and had to pay 60.00 for a small carry on. I will never fly Frontier again!

I didn't like anything about the flight It was my first time and definitely my last time boarding a frontier flight. Their counter agents need training and they need to learn to communicate regularly and respectfully

Flight was 3 hours late leaving. Poor communication from the staff about delays. Impossible to get in touch with customer service (by design). And it actually didn't come out to be much cheaper than a non-budget airline! Not worth the headache, I'm never flying Frontier again

I did not enjoy the trip home on Frontier for several reasons: there is too much cost besides the flight, which was more than I would normally pay, then having to pay for luggage, and carry-on, seat (if you want to reserve when booking) then you must pay over $3 for a can of soda, and $4 for a snack. A cup of water is free.

Flight was delay 9hrs and nothing was provided at airport, had to go and get a room to sleep in, paid for Uber back and fort with no offers until we landed back home a 1hr later for a $75 voucher for a future flight.

Got ripped off by chatdeal. For 318 would like my money back. Neal. Did not take flight
