I have taken 4 Alaska flights in the past 3 weeks and every single flight was delayed. They give you a $12 voucher for airport food, sometimes too late, after you’ve already eaten. That might get you a bagel. Reservations, rentals, etc have to be cancelled with no repercussions. Will be avoiding Alaska if possible.

I have taken 4 Alaska flights in the past 3 weeks and every single flight was delayed. They give you a $12 voucher for airport food, sometimes too late, after you’ve already eaten. That might get you a bagel. Reservations, rentals, etc have to be cancelled with no repercussions. Will be avoiding Alaska if possible.

Window seat and a packed plane. A very uncomfortable flight.

My flights went about as good as they could be. I’ll always take Alaska when possible.

Excellent flight, hour and half flight so no food was served other than pretzels, which was fine. Excellent , very professional.

I made a mistake with my reservation and customer service refused to help me. They basically said that it was my fault and that I need to pay for another flight if I want to make changes. The flight was delayed. I should have checked before I rushed to the airport, but it would have been nice to get an email. At the airport, the waiting area was too small, so there wasn’t enough space to sit. During the flight, there wasn’t enough air and there was a terrible odor on the plane.

I wish it hadn't been delayed. I'm thankful my husband got home safely but I understand turbulence was NOT GOOD.

The flight duration is 1.5 hours. Besides the point of 2h late…

SFO gate staff super fun playing music and singing having customers waiting to be boarded to participate. Flight staff was nice enough. At least not rude like others I have experienced.

I was delayed for three hours. I didn’t really like anything.

Quick boarding No carry on fee Free beverage Reasonable price

Did not like the fact that I was charged to take on a bag I usually put in the overhead

My flight was delayed, not by much.?very good communication during fest and waiting to board.

Communication with airline electronically was difficult. No number seemed available to talk to customer service.

What could have been better is if Discover credit card would be able to purchase food

Crew was inconsistent in instructions in advising passengers about seat backs during take off. Perfunctory announcements except from cabin.

The experience with Breeze was really great. The app makes managing flights easy. You can check in on there 24 hours in advance, and your boarding pass is there, too. The flight crew and the staff at both our airports were wonderful. Snacks and drinks were reasonably priced. The seats were very comfortable, they even had adjustable headrests on every seat. The only downside is not having entertainment or Wi-Fi available onboard.

The price is amazing. I was worried about how the flight would be as I never flew then. Seats were very comfortable. We had lots of legroom. The Akron airport was really nice. Overall it didn't have the stress we usually experience with flying. Highly recommend

Flight delayed and moved to another gate. Got a text message updating the gate as final boarding finished. Missed flight, fighting for my refund

Prior to boarding we were told the flight was still on time up until about 20 minutes after the scheduled departure time. Details on the new departure time and gate were not provided to us in a timely fashion and we were lead to board a flight to Pittsburgh only to realized upon scanning my boarding pass that it was the wrong flight when signage at the gate said Providence. However, once on board the plane was comfortable and staff courteous and nice.

Perfect. Even got a screwdriver in Pitt to fix my sons luggage. Awesome airline.

Airline did not explain reasons why flight was delayed two hours. Explanations were badly needed and rarely provided. Problem seemed to clearly be the airline’s fault and not the fault of the weather or airport.

Very uncomfortable seats and seat backs, and I am only 5’9”. Delayed due to crew issues, spent a long time with no ventilation. Teeny overhead bins. Wifi worked well. Arrived safely.

I was delighted that we were able to get on the 4:40 pm flight rather than our original booking at 6:55 pm!! Other than that, the flight was comfortable and landed early😊

Our flight was delayed many times throughout the day. The final delay was about 8 hours. I spent time in line to speak to someone at their understaffed desk, and also spent time waiting online and then chatting with a service rep. None of the United employees were any help at all. I desperately wanted to go get rest and possibly re-book my trip but I was denied any compensation or voucher for a hotel. I was repeatedly told it was not United's fault and therefore they had no compensation to offer. Overall, a cold and callous experience.

Paid WiFi was only available for a few minutes. Avoid at all costs.

Everything was great, only problem was that flights were delayed

Flight crew and pilots did great. Flight way delayed due to a part needing replacement. Based on what the pilot indicated- the maintenance crew could’ve resolved this more efficiently than replacing whole part- and taken less time

Pretty turbulent, but not anyone’s fault. They got us there. Impressed that they carried on with a drink service.

Please please take consideration when setting cabin temperature. The vents were not functional and it was over 70 degrees in the cabin during the winter months when most people are used to much cooler indoor temperatures. I was down to my white t-shirt and the sweat pants I wore from Auckland to San Francisco and was sweating profusely and there was NO VENT!

The best part was we weren’t too delayed. Seating space in economy is insulting and about as uncomfortable as one could expect before mutiny breaks out. Prep for landing happened well over 45 minutes before wheels down: no final garbage pickup and it interrupted those of us who needed tray tables down for dinner, etc.

Its so random that they only allow 40 pounds on checked bags when all airlines take 55. They then charge you for each 10 extra pounds, so my checked suitcase was $130 and the flight $30 ... its like whattt, im for sure not traveling with Spirit again

So bad. The check in process was laborious and the check in agent didn't seem to know how to manage the process efficiently and was confused about how to check in my son's sports equipment. The baggage fees were outrageous and so expensive. $90 for a carry on bag? And $200 additional for 2 check ins. The security lines were insanely long and the terminal was not very nice in the Spirit area. $5 for a water on board. It was my first and last time flying Spirit - I tried to save $ by flying them due to the accommodating schedule but I should have paid for Southwest, because it would've actually ended up less expensive due to the free bags with Southwest. There were no charging ports on the airplane, no wifi and really uncomfortable seating. The flight crew were great though, courteous and efficient in their boarding. Flight was delayed 1 hour, but we made up 15 minutes in flight.

My experience was better than expected. What I did find not so great was the seats. Very little room, they did not recline and the tray table was the size of a post card. There was no food to try, just standard snacks that you had to pay for and I don’t know of any entertainment. I would fly again even though everything was an upcharge. Flight was on time with little disturbance

thy don't even ofer water we have to buy it for $4.49 and paid for our cary on bags $100 each we never will fly in this company again.

Super cool and laid back, three lovely ladies. Couldn’t ask for better service.

It was fine. Boarding was a little rude. On flight staff was great. The cost to purchase everything was a bit annoying but I get that's the business model.

I liked the fast check in and boarding. The flight fare could be a lot less than what I paid…..

Minimalist interiors are great for legroom but terrible for comfort.

The cost of the ticket was great its literally 1/3 of an equivalent swa ticket

Seats are extremely cramped. There was't any type of complementary snacks and there was zero entertainment provided beyond purchaseable wifi.

The check in at the airport was awful. Told I need to pay for a bag. The item was taken at screening. I went back to get my $ back and they gave me a coupon with a QR code that doesn’t work. Worst costumer service ever!!!!!

4 hour delay because they used our aircraft to fly a different segment (per the captain)

Lost baggage on my connecting flight. 24 hours later, still no update on my bags.

I had to cancel within 1hour of the reservation an they put you through hell to . no live customer service desk. I'm handy caped and they make it almost impossible to cancel. They are steeling my money. You should not have that airline on your site. Contact me and I will give you all info. Of what the are doing to me just notable treatment they are set up like that to take people

The flight was delayed and I had to cancel because I would have missed my connection and there were no other flights for the next two days. They also lost my bag!!

absolutely horrific. delayed flights, overbooking. over charging. nightmare service beyond words. stay away.

late late late late no accountability no refund no adjustment no reasonable solution

My husband didn't get boarded on this flight. He was asked to pay $50 extra by the Frontier staff to get two boarding passes for check-in at the Las Vegas airport. He refused to pay this extra $50 charge and tried to do check-in online by himself but it seemed to be late with only 7 mins left. It ended up that my daughter and my husband missed the 7-minute time window. They had to take the next non-direct flight which took more than 12 hours from Las Vegas to San Francisco, a very poor experience for them.

Frontier is a no-frills airlines were the focus is low cost. You get basic service so don't set your expectations high. Watch out thought because this airline, like a few others, will try to nickel and dime you.

Several delays in a row totaling two hours with no information announcements and no explanations given. Rude and unapologetic onboard flight attendant addressing those of us in overpriced emergency exits as if we were idiots. It had been a while since I felt treated like cattle. I will do my best to avoid Frontier as much as possible in the future.
