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

My flight from Denver to Minneapolis was excellent. My flight from Minneapolis to Denver was one of the worst I flights I have ever experienced. I had a window seat, the gentleman in the middle seat was morbidly obese and SW should have made him purchase two seats. His elbow dug into my arm most of the way even after I asked to please be careful. I was literally squashed between the him and the window with no wiggle room. The plane was full so it was not possible to ask for a different seat. I realize I should have complained to the flight attendant but I didn't feel anything could be done to rectify the situation. I fly SW often, I will continue to do so as this was my first negative experience.

Everything went smoothly and we even arrived a little bit early.

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.

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.

Serving a coffr Or a Drink would have been nice.

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.
