One of the crew performed a hilarious skit to accompany the standard instructions. Passengers enjoyed it so much they applauded at the end!

We had a nice flight. Boarding was easy, our seats were comfortable and the on board service was pleasant.
Excellent experience. WiFi worked on this leg of My trip
I used to fly SWA all the time. I know the crew has their little acts that are often fun, and entertaining. On this flight one of the crew was just not nice. Very surprising.
Crew was pleasant; flight was on time. Paid extra for early bird check-in and still got B boarding.
If your boarding Military, it should be with ore board, and with my spouse, so rude and stupid to not let us board together and before a group. All the other airlines clearly understand Military courtesy, this is why I Rarely fly SWA and Always fly Alaska
The crew was nice. Boarding sucked. Instead of loading from the back to the front people just sat wherever and you had to wait for them to move to get to a seat. And the flight was 30 minutes delayed.
The crew was dutiful but seemed detached and bored. The boarding process is ineffective. No reason I shouldn’t be able to sit with my wife. I checked in at the first available minute and still got boarding tow “C”. Southwest used to be my first choice due to value. But no longer. Southwest is like traveling in a cattle car. Suggestion: be the first to make Wi-Fi free!
wifi wasn't working correctly so couldn't watch live tv
Flight was delayed by 12 minutes. Boarding wasn’t fun. The crew was nice though.
We arrived early and finally made it to our gate almost an hour after.
Was a pain having to leave the plane and reboard but glad the plane was fixed
Plane was was better than th YVR to ORD flight but was a fraction of the distance. Fly your better planes on longer distance flights.
Nothing wrong with the flight itself. But due to 2+ hrs waiting in immigration and the additional security checkup in O’hare, I nearly missed the flight.
They need to improve their boarding process. Group 1 and/or paying first class passengers shouldn't be in the middle of boarding process
late departure due to some unspecified issue with ventilating the cabin. They got it running but it was FREEZING for the whole flight. I asked for a blanket but they didn't provide one. They could not turn up the heat. it was quite miserable.
I still prefer Delta, but Delta doesn’t fly to State College PA.
Everything was fantastic. Modern plane. All the amenities! Although the paid snacks and meals are pure robbery. Like i understand airlines need to make money, but 11$ USD for an overnight oats with some nuts in it and barely any pieces of apple.... Highway robbery
The flight was bumpy. No Breakfast or coffee was served, not even a bottle of water. The food was okay but odd. Rice with peas instead of couscous with some unknown green thing. United Airlines did not tell me that there was VERY LIMITED HANDICAP SERVICE IN NAPLES. De-plane via 20 aluminum steps. Taken to Van. You must walk into the terminal, find luggage, and then walk out to the rental car pickup spot that is 1 block from the terminal.
Crew did their best but the plane configuration is too tight if you're bigger than an average sardine. Controls for the entertainment system didn't all work. The aircraft hadn't been cleaned in awhile.
The meals were mediocre and the alcohol selection was poor. I enjoyed the selection of movies and other entertainment.
I chatted with the captain before the flight, and similarly during the welcome announcement, he warned of a turbulent flight that may impact the in-flight service. However, once at altitude, he announced that the weather changed and he immediately turned off the seatbelt sign. But it appeared the cabin crew had already decided to take off this flight. They remained seated and then just chatted in the galley. The flight was fully catered, but only first class received service.
They didn't have any gluten-free snacks, oddly, which I require...or any flavored soda water or decaf tea options, which seems to be standard.
My flight attendant was attentive! The elderly person next to me was flatulent and the flight attendant could see that I was in distress and brought me some face masks
It was as expected for such a short flight. No complaints
My boarding pass wouldn't pull up in the app very easily and had to really dig through my email. That caused a delay in TSA..
I had a TERRIBLE experience with the AA crew. I believe it was disability-related. It’s unlikely I will fly AA again.
Baby cried a lot. Nothing anyone could do about it. Just part of flying.
The flight crew was fantastic! Which the seats had a small TV.
The flight was delayed till next day ! They kept delaying every 30 minutes then after 3 hours they delayed it till next day. We kept waiting in line standing more than an hour to get the hotel and meal vouchers. There was no communication at all. Everything was bad
The people were wonderful, but I hated the way they over charged for luggage, especially for stops which were charged the same as starting point to final destination.
First time flying Spirit and I was pleasantly surprised. Service was as advertised. Crew were very professional and friendly and excellent in dealing with a customer who felt ill on the flight.
Fantastic. Had handicapped traveler and they helped us through security, helped with boarding, helped put wheelchair together, and were all very patient. A pleasant change from previous spirit flights I’ve taken. Highly recommend.
Spirit's seating does not work for an overnight flight and my back is killing me. This airline does not meet the minimum standards for being an airline.
I was booked to Reno with a carry on and a personal item on Alaska airlines. Kayak booked me on a return flight on Spirit on which I was not allowed a carry on. What a nightmare. It cost me an upgrade on Spirit and a checked bag fee, a total of $125, to get a small carry on bag home. Kayak needs to learn about the Go restrictions on Spirit before quoting a price on a round trip ticket.
Seats had more cushion in this flight. Otherwise, I got what I paid for. Will avoid spirit airlines at all cost.
This is the first and last times I take spirit. It’s really bare bones. That old saying that everything comes at a price, that’s really applicable here.
The first flight was delayed which would've caused me to miss the connecting flight. It wasn't the first delay of my overall trip with spirit airlines. They were both due to crew. I was offered a credit after I cancelled my newark flight, but honestly, I won't be flying with them ever again. It's absolutely ridiculous that a full refund isn't given considering it wasn't something mechanical or weather related. It's literally their own crew being late.
Well, the seats were SO tiny. I’m five-foot ten-inches talk as a woman and thank god I wasn’t more than 150 pounds as I would not have fit at all. I understand there are the “big seats”for an upgrade or a blocked middle seat but I was not prepared for the size. Also, there was an incident on the plane with a man who wound up being escorted off the plane at landing by TSA… I understand this was not in the control of the flight crew BUT the flight attendants were arguing amongst themselves at the front of the plane and we could hear them. There was a flight attendant in her 50s scolding a male flight attendant for “placating the guy” that was causing a ruckus and telling him “you should have been on our side not his.” Not only was this unprofessional to do in front of passengers, but it caused anxiety in nearby people including myself. We don’t want to feel like there is a potential danger on the flight - 9/11 flashbacks. The flight crew should remain calm and I believe the male flight attendant was in the right in trying to calm the man who was an issue.
Comfortable and plenty of. Having to buy water and coffee, though is ridiculous!
Delayed each time on a round trip with no significant weather interference. Updates to flight times came after the fact. 30 min behind in boarding and board and phone still show an on time departure. Some mysterious extra 300 miles that came so surprising they had to fuel while we were already on board?
A lady asked to stop the flight after the tunnel pulled away and we began to depart a flight that was already hours late. The attendance respectfully stopped the the plane and had the tunnel return. After the tunnel returned the passenger claimed to have changed her mind . The tunnel was then put in reverse and the passenger remained on the plane .. They should have sent the sick passenger off the plane like initially replaced. They existed a couple off the plane prior to that situation.. So.. all and all.. it was a long and flight.. .
terrible cascading delays and unhelpful customer service. uncomfortable plane. crew was great, however!
I ended up paying $70+ dollars to for a carryon because the website is confusing and misleading. I now realize I did not need to pay that. I request a refund. I will pay extra to other airlines and not fly Frontier again.
With frontier you get what you pay for. The flight was two hours late. It’s a tight fit for the number of people they bring but you get to where you’re going cheap. Sometimes that’s more important than a nifty drink and cool TV..
Charges unexpected. For seat that didnt recline. Please reverse extra seat and carryon charge. Bad business that is a bait and switch.
Although we received an email from Kayak AND the airline, turns out we were not on Frontier’s manifest for the flight. We had to purchase tickets at the gate. Not sure where this transaction fell apart, but it did. We are now disputing the charges for the SLC to PDX flight originally booked through Kayak.
We had an awful experience getting our bags checked in. Frontier’s check in on the app manipulated us into buying the business package because that was the only option available for a checked bag which included two checked bags per person which we did not need. Upon arriving to the airport, we stood in line for what seemed like forever at the baggage check in and there was no one available at the counter. We were first in line and we were afraid we were going to miss our flight due to the baggage attendant being late. After realizing there were a lot of other people waiting at the baggage check in and no one available. I reached out to Frontier and could not get any customer service so I had to call the airport to page the baggage attendant to send someone to the counter to check in our bags before we were able to go through security , I finally spoke to the attendant at the counter and explained to her that we had to pay for two checked bags person a total of six bags when we only had a total of three bags between three people she said to reach out to Frontier and they would issue a refund for the three bags that we paid for and did not need. I reached out to Frontier which I was not able to reach anybody by phone so I had to go through their automated chat feature, which sent me around in circles until I finally reached a representative to assist me. I explained to them what happened and they explained that they were not able to assist me. I continued to push the issue with them as this was very frustrating and they finally put in a customer service ticket where we were issued a flight credit and we were so disappointed because after this experience, we NEVER want to fly Frontier again, and we do not want a credit that we will not use. Frontier charged us almost $500 for us to check three bags which is absolutely absurd! The customer service agents were not able to offer anything else other than a flight credit and I do not feel like my frustrations were truly heard , we will never use Frontier Airlines again ! Truly Theft by Manipulation! They should be ashamed!
I couldn’t check in because the app didn’t work. It took 3 Frontier employees at the counter to get me checked in. Flight left 3 hours after departure time
One crew member was rude about our bags. Be nice about it. We don’t fly a lot. And the fact that you have to pay for a carry on is ridiculous
