The plane was delayed a bit. It wasn't a huge problem though, as we were heading back home.

Flight was great. Boarding was crazy because another flight was boarding late next to ours so everyone was standing and in the way.

very good but no blankets for overnight flight or tv screens…

We were in 1st Class. Excellent service. Easy boarding. No too difficult to speak with someone on the phone. Breakfast was not eatable for me. No screen to watch movies. I don't have or want a tablet. This is first class there should be screens. Even if I had a tablet there was no place to put it. There is a place to put a tablet in economy. Seats were a bit lumpy.

A cheerful and effective crew. Tasty pre-order food options.

My youngest didn't have a assigned seat until we biard6the plane.

There was no seating at the gate, no where to charge your devices, super crowded. Boarding in group F meant all luggage space was taken when it was time for me to board. The boarding crew was short with everyone and seemed irritated. The luggage space was insufficient, the seat was too small for me (6'4") and very uncomfortable trip. I was in a middle seat between a person snoring the whole trip and a person with very strong body odor. The flight crew was terse and unfriendly, seemed irritated and impatient. Yelled a lot at people with earbuds in, understandable. Finally, we arrived 10 minutes early, only to sit on the tarmac for 20 minutes and wait for a gate. Worst flight experience I've had in years.

The flight was delayed by 3 hours and 30 minutes without any explanation.

A little delay but nice flight, nice team. Thank you.

They lock the bathrooms too soon before landing! My bladder was bursting for over an hour. Then the plane had to sit on the taxiway for 1 hour. People started rushing to the bathroom. Creating a dangerous situation.

Most aspects were good however if they assign boarding zones they ought to enforce them or why bother? My luggage from SAN-JFK-MAD was lost in NY so I without my main bag for two days upon arrival in Spain. They were helpful in tracking it and eventually delivered it to my hotel. The flub was because of a delay upon arrival in NYC. I had booked 2 1/2 hours between flights but we had to hold on the taxiway for an hour after landing while waiting for a clear gate which likely caused the baggage error.

Excellent flight, the planes were newer, they did a nice job with boarding, great service overall.

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

737-800 in first class was pretty dumpy. Seat had an uncomfortable angle, storage under the seat was blocked so even my very modest backpack didn't fit, power outlet was flaky. Weird tiny seat pockets that couldn't hold a gallon ziploc bag, emesis bag missing, etc. etc. No in-flight service due to turbulence. Crew was excellent, boarding was smooth despite a full flight.

Food from the flight from Atlanta to Santiago was very poor..

Delta flight was on time, seats were comfortable, and crew was nice.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

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

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

Flight left early and arrived early. the whole trip was excellent.

Same as ive said before. All airlines and TSA need a massive revamp.

Alaska airline sis usually great. However flying nowadays is so stressful and feels more like an interrogation rather than a fun part of the vacation experience. From the TSA to the cramped seating it feels like i am entering a concentration camp having my picture taken via TSA and being forced to have my body scanned. Then we are forced to sit in beyond cramped conditions where our knees are crushed into the back of the seat in front of us with almost no movement possible constantly being reminded to put our seats forward when we want to alleviate the horrendous pain of our knees being shoved into hard plastic. My knees looked like i had kneeled on gravel for 2 days straight after flying for a total of 14 hours for my roundtrip. I keep hearing from our elders about the jopys of flying in the 70s and 80s but now it feels like the joy has been removed as a means of acquiring more financial gain by the airlines. Not to mention that my flight via hawaiin airlines was delayed so long that i had to miss my connecting flight which then forced me to miss another day of work and the only recourse i had was a wonderful conversation with a lady via Alaskan Airlines when she got me a new flight the next day due to the delay. She was very pleasant and helpful. She got me onto a nother flight the following day but when i have to travel 2 hours from springfield Illinois to st louis it was a huge hassle having the delay in the first place. Not even the tiniest bit of compensation was offered either. Not a voucher, not a free meal, not a slightly better seat, just a reschedule when in no way was the delay or the missing of the connecting flight my fault. I want to reiterate that Alaska Airlines is really one of the best airlines overall. I fully understand they dont control the TSA, but it does effect the overall experience when TSA is making it feel like we are going through a re-education camp with rather strange videos playing on the walls the entire way through Security. With that said, Alaska should take cosnideration from years of past and make the flying experience fun again. I understand profit is important, but if just ONE airline made flying like it used to be 40 years ago and stopped making it such a money-driven experience, then i, along with many others would choose to fly more often. We see the smaller soda cans and we laugh, we see the tiny snacks and scoff, we see the ridiculous wifi costs and choose to not pay for it because we download our own prior to flying. Why not get everyone to use the wifi by making it like 2 bucks rather than 8 bucks? Make a much larger first class area with slightly lower costs so it doesn't feel like we are mere peons boarding a cattle car? Create some more leg room and watch how fast people are clamoring for your airline over others. Not one airline is actually catering to the general public, if they did, they would see so many people seeking out their airlines above all others and it is just that simple.

Both flights were late 2+ hours with ZERO communication from the airlines or their staff. No offers for compensation. WiFi didn’t work for streaming and they said to only use browsing but that didn’t work either. Waste of $$. No drinks only boxed water or apple juice. No snack. One of the worst flight experiences I’ve ever had.

If I knew I would be on Alaska Airlines flying back, I never would have bought the ticket. My flight kept getting delayed and Alaska always seems to be late which is why I don’t fly on them.

Good. They changed our gate very late and then when we landed, we had to wait 20 minutes to get off the airplane because another plane was in a slot.

Flight was canceled with no voucher of any kind and next available flight was two days later.

It was very pleasant. The staff and crew are very polite.

On time. Alaska upgraded seat comfort with memory foam seat covers with head rests

the people at the counter, NEED TO BE MORE HELPFUL. we had three suitcases to check in and we were not trying to be an INCONVENIENCE TO YOUR clerks. but she was not helpful and made our trip back home memorable but not IN A GOOD WAY. Sadly to say, you guys need to teach to be and to go above and beyond to help THE CUSTOMER BY ANY MEANS POSSIBLE. they need to leave aside whatever they are going thru in their lives, THEIR WORK DEMANDS THAT OF THEM, IF NOT THEY ARE NOT IN THE JOB THEY SUPPOSED TO.

Not happy that I booked a flight and after I booked it, you guys changed it when I could’ve got another flight and got to my destination on time then got sick and was not able to make the flight and try to make arrangements to reschedule my flight, but because it was a basic flight I wasn’t able to reschedule it without it costing more money so no, I will not be using your guises airline due to the fact that you guys haven’t been pleasing to me from the start thank you

Good experience except for the drunk woman who was with a child. Sad

Too many time late and postponed No electrical power for my electric devices

Spirit is by far the worst airline to travel with, period. Seats are cardboard, flight attendants need anger management and if you ask for water, you’re basically a criminal. I don’t care how much it costs but I will travel with an airline who actually cares about their customers. Oh and one more thing, the next time your gate agent puts his foot on someone’s baggage's scale, I hope they get what’s coming next, a viral video of your scams. You suck Spirit, do better.

I mean, it’s Spirit. But it was frustrating to have our flight canceled, get bumped to a later flight, and then Spirit was unwilling to check our bag until 4 hours before our flight… tell us we could not sit in the waiting area’s chairs… and really negative experience getting checked in and dropping the bag.

terrible service, no room for a dog underfoot, a broken chair that is impossible to sit on and all this costs a lot of money

It was fast but uncomfortable seats. Had to pay a bit extra not sure why? Maybe in selection of all my 4 tix together ? Just knew I had a balance before getting boarding pass online when departing from satx ? And flight was delayed..

Last minute 2-3 hr delay in flight schedule; no explanation Unexpected extra $52 charge What's the benefit of choosing a cheap airline if you trick people last minute and force them to pay extra last minute? Did not appreciate being cornered.

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.

Surprising everything went well. Nice attendants and fast getting on and off the plane. Overall, was happy with the experience.

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…

Cancelled flight after I arrived at airport after 75 min drive and parking. Next flight was 4 days in the future. Had to scramble and buy a much more expensive flight on another carrier.

I never got to experience the flight because they delayed my first flight and I missed this one. Then Frontier didn't want to help me rebook a flight to get me to my final destination.

I liked the turn-style feature at gate 209B at LAX. Very efficient process. The gate staff also made several, clearly directed announcements so I felt very informed.

The seats were awful, hard plastic covered in sheet vinyl. The airline tries to scam you into paying extra to get seat together when the flight wasn’t full. They were going to separate a family with young children but my wife who had a row to herself gave up her seat so the young mom could be with her young boys. I’m never giving this airline my money again.

It was a short flight so no food or entertainment….

Frontier had yet another flight cancellation. Have never made a complete round trip with this airline without at least one leg getting cancelled. Miserable flights - dirty, uncomfortable planes that apparently always have issues since I've had multiple delays and cancellations with them.

Flight was delayed 3 times, would have been nice to have received text message instead of email notifications. Frontier app wasn’t even updated accordingly, no gate number disclosed. No agent at front desk of gate to inform of delay. Very confused and left if the dark

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

No frills for sure. No gate announcements about flight delay, not even water to drink on the flight.

I loked walking out on the tarmac to board and no first class. I didn't like that they have no snacks or onboard wifi to bide your time.
