Airline reviews

Did not travel - unexpected medical emergency. Nonrefundable tickets, but Alaska Air sent credit vouchers for the entire amount (very generous, and I didn't expect that). However, I paid for insurance with Kayak's partner company. The 'insurance' might pay for lost baggage, but they referred to the contract in refusing to a dime on the policy. (If you died from a heart attack in the waiting area, I suspect they would claim the right to DENY if your general practitioner had found high blood pressure previously and prescribed daily HTCZ pills - even tiny ones.) They described a policy to deny any claim with even the slightest whiff of pre-existing. I suspect that they probably almost NEVER pay money out on a medical claim, and that their 'local medical assistance' has no coverage either - that it's just an abusive profit center sending gigantic bills while contributing nothing from your 'policy coverage'.

Not good. Didn’t get to our final destination. No reimburseme t for lost time

It was fine. Very friendly crew. Smooth flight. Landing was a little rough though.

Start to finish perfect flight. I'll be traveling from Cleveland to Seattle more often, And I believe you're going to be my go to

Delayed had to stand for hours guy beside me was to big for his seat and crowded me I paid for upgrade to be stuck there Not much beverage or food service

Short flight so little time for any beverages or snacks-there was no entertainment on this flight

I am shocked at how utterly mediocre the First Class experience was on Alaska Airlines- I really expected better. There was a delay with the food delivery, so we sat on the plane for an extra 30 minutes- not once during that time was I, nor anyone else in First Class offered anything at all, not even water. There's no tv or entertainment available? Really? In modern day? And the Wifi was $8 for the connection that actually works, but free for the connection that didn't work at all? What century is this? While friendly, the staff seemed to be much more concerned with their own personal time while working- listening to headphones, on their phones until someone needed them, I'm so disappointed I can't even believe I was able to find these words.

The flight check-in process was awful. At Seattle Tacoma Airport the Alaska employees couldn’t properly tell me how to/where to drop of my checked “ski” bag which I had already paid for. Boarding was slow and disorganized as well. The baggage claim in Denver was almost as bad with broken carousels (airport employees had to carry bags out to us by hand) taking over an hour!

I would fly again. My trip from Newark to Seattle had a 3 hr delay. Disappointed.

I needed to board early and that was no problem. The snack was just ok. Alaska is an EXCELLENT airlines . . . luggage fast and easy.

The WiFi didn't seem as fast as it normally is

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

The crew was wonderful and attentive. The seats near exit row were restrictive. Offer healthy snacks please

Other then mechanical/ computer problem and 3.5 hours flight delay the flight was great. I guess that what happened when you fly an old airplane now a day.

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

Bottom seat cushion is almost non existent. Very uncomfortable seat.

Coach seating is debilitating, neither my husband or I can walk the following day

Luggage delayed and 6 days later I still don't have it.

It was NOT pleasant. Started from checking our luggage to the last time getting off the plane. The crew was not friendly, the food was horrible and the seats were too close to each other that I got a bruise on my knee.

In thirty years of traveling, mostly with Delta, this was the worst day ever.

Between Las Vegas and Dallas was okay But, once in the Dallas airport, notice, I have disability and ask for a wheelchair, they leave in a middle of nowhere, the personal in charge try to push me on a cart where I couldn't sit because was to high. Then they don't care about me, they bulling, till I start to yelling and crying, ask to everyone around, who can help me. The man in charge make a despective movements and said you are to loosing the fly. The last name in his batch started with an H, I did not have the full name. A nightmare. After all, a woman in charge was walking very slowly and asking me for a tip cause she was helping me to reach the fly. For years, AA has been the preferred airline. The personal in charge of the disabled people are discriminate me. Thank you Kayak.

Flight was late and missed connecting flight. They could have better accommodated, but instead did an overnight and had to arrive the next afternoon.

April was the flight attendant in first class and was the most pleasant, cordial and efficient person I have seen on a flight in years. Good example of the type of people AA should hire to increase customer satisfacdtion.

Two flight changes before the scheduled flight. On the day of the flight, the flight was delayed, which caused the connecting flight to be missed. Then, I was directed to another airport (CUN) and traveled to Tulum. American gave a $12 voucher for lunch. The least expensive item on the menu at a Mexican restaurant was $9.99. Driving to Tulum was a bad auto crash, and traffic was delayed two-plus hours. The bottom line is that we should have been at the hotel at noon, but it ended up at 11:30 PM.

Everything was great except it became so hot on the plane I couldn’t sleep on my red eye flight. It didn’t really cool down till we started descending.

The boarding experience was good; $20 for wifi per flight is uncompetitive compared to Delta, Southwest, and others, and puts American lower on my list given similar pricing.

Flight didn’t get dinner on business. I was starving!

The only thing is if Wi-Fi is available after you land and taxi to the gate. It takes forever to get to the gate, and having the Wi-Fi continue would be great to bide the time at least 5 minutes before you arrive at the entrance. That is my only comment; otherwise, everything was good.

I had two wonderful flights - very relaxing and got me there early!

I wasn’t happy with the hour delay from Dallas to McAllen, but that is the nature of travel. I don’t like to fly in general because of all of the problems all the time.

Most uncomfortable seating I have ever experienced. And they do not provide any beverage unless purchased. Water was 4.59 a bottle. Same for a soda. A cup of water should be free. I will never fly Spirit again.

Seats are uncomfortable and too close together. Also, you missed my connection in Vegas on the way back and I ended up sleeping in the airport, flying back to Burbank instead of LAX and I got home 12 hours late.

They are very particular about size of the bag. Mine is small bag and has wheels. Bag wheel edges are bit outside of the measurements bucket. They charged $99 as carryon bagage

Your crew is a representation of your Standards and Values. The crew from Seattle to LAX, was very disappointing. The crew was more interested in hanging out at the lobby area. Talking, laughing loudly and eating all the snacks. They did not do regular rounds to see if customers needed anything. This was a huge disappointment. I will no longer be flying with your airlines moving forward.

Non-professional acting crew, Very uncomfortable seats…!! Very bad pricing with all the add-ons for seat choice, luggage fees, etc….soon you’ll charge extra for oxygen. The ticket price means Nothing because in the end, the actual amount i paid, i could have and will in the future continue to fly on a real airline…

Your employees need to learn how to talk to people as creations of Yah. We are not their children nor are we lower than them.

Seats were surprisingly comfortable, and crew was polite. I did not like the baggage fee prices, the minimal amount of flight choices for my area and the difficulty of the self service bag drop.

I did not fly Spirit. Connie used my email while booking her flight. I do not know Connie. It's fraud!!!

Flight was ok with exception of the multiple delays. As with all Spirit flights, the sights are extremely uncomfortable and lack leg space. However, the price savings is the plus.

Okay for the most part but Good boarding and on time

Asked for a seat change to be w my wife at the gate they were great in sorting it out to make it happen

Everything went as planned. Crew was great. Seats were still not that comfortable.

The plane failed preflight inspection, so we sat there for 90 mins while they tried to fix it. Ultimately, everything was remedied and we made our connecting flight; instead of a 2 hour layover at the airport, we spent it waiting on the plane.

They changed the timing , first delayed by 4 hours then went back to 40 mins late, we had to run back to airport to not miss our flight. This is ridiculous

Seats were extremely uncomfortable and it was very hot on the plane.

Would be great if Frontier can Assign Seats together under one PNR

Early arrival. Great landing. Pilot updates. Too cold in plane.

Better to put road truck seat in plain it so uncomfortable can not adjustable and fill metal don’t have cushions at all it’s very hard to travel for five hours

Since they are a budget airline, I wasn’t expecting too much but they did some things well. They were on time, the plane was clean, boarding was fairly straightforward and the staff was cheerful and friendly. The only downside was comfort. The seats were fairly hard and after a 2 hour flight your rear end is not feeling so great. Maybe a little more cushion in the seats, Frontier!

They cancelled the flight and did nothing. I should be compensated for my uber rides to and from airport. Not a good service by frontier or kayak.
