Southwest has inacted unfriendly customer policies like other airlines. Watch the fine print very carefully if you are having to alter flight arrangements. Rules are now complicated and very stilted to travelers sacrificing travel funds (unlike before where the simple, straight forward flight change policy was worth the extra premium for ticket price.) On the positive side, SW Flight crews are still wonderfully helpful.

Poor customer service, no accommodation for passengers when the flight was delayed over 5 hours.

The flight was late. The crew was rude. There was no food. Cramped and uncomfortable. Nothing about this flight was good.

It was great. The gate staff were very helpful in Portland when my son forgot his rolling bag and had to go back to get it just in time to make it on the plane. We really appreciate that. Great job!

This leg was much better, but we did have to have a 3 hour lay o er after coming from a very exhausting hiccup with our flight from BNA to Den

Connecting flight is on time and boarding was a breeze!

Southwest has a serious issue with keeping their passengers in the dark about delays. They also appear to lack the necessary crews to deal with any sort of hiccup in their operations. The way they run their day-to-day operations is a joke. You are telling me that a hail storm in Denver, where hail storms are incredibly common, results in hours of delays due to every plane needing to be inspected for hail damage? Understandable, but there seems to be a skeleton crew of maintenance workers undergoing this daunting task. There was no particular order of inspecting planes, leading to some planes only having an hour delay or less in others having four or more just because of the luck of the draw of what plane got inspected with no consideration to how long the respective delay was. The entire time the passengers were told nothing except the fact that there was lightning in the area and the ground crews could not load the bags. This always happens that Southwest will incrementally delay a flight with no information given, leaving many frustrated passengers fuming once they find out that their flight is canceled. Don't make people wait around for hours at the airport giving them no information, just to keep them on the hook and prevent any action from being taken by the passengers in terms of finding alternate routes of transportation or accommodations for the night. How many hours of people's times do you think you waste by operating like this? How about having a fully staffed crew in one of your busiest hubs that is famous for severe weather that can effectively deal with a situation like this, or how about having planes on standby to quickly replace in case something like this happens, like all the other major airlines do. This is just like the Christmas fiasco but on a Denver scale, but again this is literally just from a single thunderstorm going over Denver in the spring. I'm glad I've stopped using Southwest as my primary airline and have switched to United. Every single time I fly Southwest, something has to come up. It's ridiculous and I seriously can't wait to finish using my miles so I don't have to deal with your garbage anymore. You used to be so good and I don't know why you thought you could just scrap your quality and expect people to deal with it. Oh, and I walked by someone getting CPR for over 5 minutes in the concourse. I hope he was ok. Southwest needs something similar.

Flight had over 6 people in wheel chairs and there was only 1 gate agent. Very impressed though in how Maddie handled having to efficiency move that many people by herself. We still nursed in a timely manner.

I loved that the flight was not as full, so we were able to have seats available between us. I just wish wipes are available as we board so that we can clean our areas, as the window area was quite dirty in my case, on both legs of this trip, and it was hard getting the flight attendant's attention for this. She also seemed a bit stingy with the free drinks. I asked for two cups of drinks; she brought one and then waited until I fell asleep and brought the other. Not sure why...

Easy boarding, but no power at the seats and no television wasn’t a good experience.

I had called before the flight for vegetarian food. But they did not have it for me.

Flight delayed by over an hour…not their fault exactly, but it wasn’t convenient either. Other than that a great flight and STUCK the landing!

It was efficient and great. DIA took a while to let us leave but other than that it was great.

The flight crew home was so, so friendly and HILARIOUS. I’ll keep flying Alaska like I have for the last 30+ years!

Perpetually delayed, flight out was delayed almost 2 hours, flight home was delayed an hour and a half. On the way back no refreshments as an option, yet they gave it out to 1st class. No apology or notice of the delay going out both ways. Seats are nice feature wise, but the adjustable headrests don't stay up anymore. Feels more like a budget airline

My mother suffers from Lupus and has challenges walking. I specifically called Alaska airlines, stated her condition and made sure my mother’s had wheel char assistance towards gate and into the gate hall so she just had to get into the plane and walk a couple of steps. It was assured by Alaska team that the service was granted in both airports , DEN and SAN . In Denver , the wheelchair assistance never arrived. I had to personally grab another airline wheelchair sit my mom.Then I had to go to Alaska Airlines front desk twice to let them know my mother was waiting at the wheelchair service station. Upon arrival to SD Airport , there was no wheelchair service waiting for her in the hall before deplaning. She had to walk her way out in pain. Absolutely inconsiderate and unacceptable by the airline! Never again flying with Alaska Airlines.

Waiting 2 hours after landing to arrive at a gate was ridiculous.

The pretzels have no taste. How about a choice of snacks? The flight itself was fine.

Flight attendant missed us first pass with beverage. We had to ask for water on second pass as we were going to be missed again.

This was not an Alaska Airlines flight, it was American Airlines flight operated by SkyWest. The aircraft was narrow body ERJ175. But it is a modern regional jet and relatively comfortable.

The flight was excellent. Their was no service as we boarded, the flight attendants spent about 30 minutes just taking and not really caring that the cabin was about 80 degrees and did not offered any beverage to first class passengers or any passenger. The flight from DEN to ONT is not long but not under an hour, we received one drink and bag of chips if you were lucky. I was in first class…. I did leave my hat on the plane and it only took less than five minutes for a United rep to locate and bring it to me.

Destroyed my suitcase. Tired of talking about it. Cancelling my unite mileage plus account.

New plane was lovely. Crew customer service is always lax but expected. Kraft on time and arrived safely.

Wonderful in-seat entertainment with seatback screens and huge selection of quality movies. The ability to bluetooth connect headphones was amazing.

Flight was late - I was downgraded from first class to coach

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

See my previous comments. I was probably booked in business but was moved to economy

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Too many fees (but that seems to apply to all airlines nowadays)

United requires seat selection in order for those booking together to stay together.

Not too much it was pretty good all the way around

The flight attendants were extremely sourly and borderline rude. I did not feel appreciated as an AA customer once.

As we approached Denver, we encountered quite a bit of turbulence. I know this can sometimes be the case as I frequently fly this route but not on American. My gripe: Usually a pilot or co-pilot alerts passengers to the possibility of turbulance ahead of time. This did not occur nor did he communiucate during what was a pretty rough ride.

Terrible. Our luggage was delayed and couldn’t be delivered for several days. We got bad information from the airline agents at baggage claim. We had to pick up our car so we wouldn’t be charged for an extra day. We got lost in the maze of airport parking. The baggage claim agents didn’t offer us any compensation for our extra time and expense. We are tired, hungry and very frustrated.

Mechanical delay and no compensation. Missed connection as a result of their delay. Mediocre performance and service. Horrible airline currently with horrible culture.

Any sort of gluten free snack option would be nice

Crew was late. Baggage was late. 2hs inside the plane waiting fro de-icing and traffic. A 3:30hs flight ended up being almost 6hs inside the airplane.

Timely boarding process, made up for lost time even after a lengthy wait for de-icing

It would have been better if I could have had my flight on time. It was delayed for 5 hours. Caused me to not be able to fulfill my promise to my granddaughters. Other than that it was a good trip.

11h50m total delay. Had to switch to another flight that was still a 7h30m delay.

I paid for the upgraded bundle. Was worth it! Great experience round trip!

It was awful everything about it terrible I will never ever ever ride it again

Crew was kind of grumpy and there was no beverage service at all. Sodas were $4. Disappointing.

12 hour delay required getting on and off plane 3 times - would have at least liked to have been offered a snack or drink

There's no seats that lean back with little leg space i wad uncomfortable the entire flight. Your charges for extra baggage is despicable and costly!!

There was no food and no entertainment, so I'm not sure why these are even in the survey, as my understanding is frontier does not ever offer food without a few, not even a snack, and there are no screens so unless the flight safety talk is our entertainment why ask how we liked it?. One of the flight attendants say in the back of the plane as people filed in to their seats, yelling orders about where to put baggage and telling people to hurry up. It was the least professional experience I've ever had on a flight.

Very bad! No good service delayed my second connection flight

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

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

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.
