I like the new adjustable headrest. Unfortunately 2 crying children were in front of us. But it was the first time and not holding Alaska accountable for that. Alaska always seems to have everything in order professional but comfortable.

Very bad, terrible food and late by 2 hours. Then no to open aircraft doors
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…
OK for the price paid but nothing as far as value.
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.
Delayed flight. Nicest crew member was a SW pilot flying seated next to me who kindly move to seat the final passenger. Flight extra delayed. My cup of refreshment of ginger ale was so packed with ice it was literally 2 sips.
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.
Flight wasn’t even full, but too many carry-ons caused us to run out of bin space. New bag fee has folks who would usually check their bags carrying on. Watching Southwest morph into Spirit/Frontier is so sad to watch
Southwest is Southwest. No frills. If you're luck enough to get a happy crew (we did), then it makes for a nicer flight.
It was a perfect flight in all aspects! Both legs!
Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.
I liked the crew member who gave flight instructions on "in case of a problem:. The seats are so small that only a young teenager could sit in middle seat.
Very good. Sad to learn Southwest is going start to charge for bags
Great flight staff. Ease of boarding. Overall, very uneventful and easy trip.
Employees were kind and funny, as always! Flight was late but no announcements were made for people with tight connections to help them transition quickly. No service due to turbulence.
Crew was excellent. Comfort seats not as nice as other kinds of planes.
It was a great flight and the stewards and stewardess were all kind and accommodating!! The seats were comfortable and entertainment screen excellent!
There are 4 flights in consecutive gates with about the same departure time. Two flights were boarding at the same time. One was delayed or boarding would be happening at the same time. I am not sure what Delta and LAX need to do to have a better layout at the end of Terminal 2
There was a security issue at the airport and we were unable to land. We circled endlessly and then landed at another airfield for fuel. We then circled the airport again, almost landed but didn’t fully touch down before circling again. I am thankful to the crew for keeping us safe- the issue was the airline and staff at the airport getting us seats on our connecting flights. That part was hours of searching for someone and getting in double my steps.
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.
Delta flight was on time, seats were comfortable, and crew was nice.
Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!
I have never flown Spirit it was much better than anticipated!
Staff was very friendly. They attended to people nicely and reprimanded, in a professional way, to those who wouldn’t listen. AC wasn’t working on the flight waiting to depart in Burbank, so it was uncomfortable for a while since the flight was delayed but then better before take off.
Good on that leg. When I arrived in Detroit I had to wait over an hour for luggage.
The crew was very nice. I would like to see them offer basic refreshments just like a soda and pretzels, etc. for free.
I missed my flight because I was not informed that I had to check in 45 minutes before my flight and I was not allowed to check in any time after that. I was there at boarding time and their customer service was poor and they told me since I didn't check in 45 minutes prior, I couldn't get my boarding pass. I received an email containing my "e ticket" which I Thought was going to get me boarded.But but they said that was just an Itinerary and it was no good to help me get on the plane. I had already missed one flight earlier that afternoon and had to pay for this flight.And then when I missed it they told me it was gonna cost me another $99 to reschedule my flight
Seats uncomfortable, hard to check luggage, etc. It was like the last flight out of Hanoi
Good experience except for the drunk woman who was with a child. Sad
The flight was canceled and no option was given to get me to my destination even though there were 3 other flights going to Las Vegas later on that night. I will never fly on Spirit Airlines ever again. Terrible service!
I book a filght for me and my daughter from Miami home to Las Vegas and getting her checked in was awful the lady at the baggage check in was horrible!!! She was the rudest person I have ever encountered in my entire life!!!! My daughter dose not speak Spanish and so I was trying to translate for her but the woman would not let me so my daughter was 100 💯 confused because she could not understand what was going on or being said at all horrible absolutely horrible and rude extremely stressful worst experience ever!!!!!!! And then we were actually told by other air port staff not to complain because if we did sprint would make sure we miss our flight ✈️ that they do it all the time 😧
Not good. No updates regarding the flight status until after the fact on the delays and then a cancellation.
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 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.
Although an hour and a half early was told by staff at check in they had overbooked and could not check us in for the flight.
The reps working at the airport counter were dumber than a second coat of paint.
My costume jewelry was stolen out of my bag. Got to airport and my bag weighed 45 pounds- 5 pounds over cost me $100 Long lines in tier one. No entertainment No WiFi no free drinks or snacks
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….
I’ve never traveled on Frontier before. If you want basic, no frills, friendly service at great prices then give them a fly!
Landing in terminal 2, but my luggage is terminal 3. We (and others) were looking for it in terminal 1. We probably missed the crew broadcast, but the communication could have been clearer for non native (or elderly) passengers.
I was not permitted on my flight and had to purchase another flight ticket to Las Vegas.
