I'm not a fan of Southwest's model. I don't like the herding style of boarding.

Flight crew and cabin crew were great. I had to rearrange flights because my original flight was 3hrs delayed for weather, the rub is the flight I moved to boarded on time then we sat at the gate for 2 hours because scheduling stole our first officer for another flight, TWICE. Then our actual FO was an hour delayed. To make it worse my original flight went from a 3 hour delay to departing 15min EARLY. Just poor scheduling operations all around.

Bring back peanuts Take our drink orders when were all seated, especially after you switch to assigned seating.

It is southwest seat was ok. Not the most comfortable seat

I’ve always loved Southwest. No issues at all. I was flying standby and the gate agent was extremely friendly and helpful. Boarding was smooth and I was able to get a window seat in the emergency exit row. Crew was fantastic! They were very professional and accommodating. We had to divert from our destination due to weather but the flight crew kept everyone at ease and informed us of all pertinent information. Excellent flight

Plz don't take away free bags and free seating

Excellent! Only question is how we check in at exactly 24 hours in advance and end up at the end of the B boarding group

It went well. Plane wasn't full. Will be great when assigned seating is in place

Excellent experience. WiFi worked on this leg of My trip

Flight was great, but golf bag never made it until later in the day. Even though I had a nonstop flight it was placed on a different one. They made it right with flight credits and I was able to get it the same day.

Gate agent did not hold flight for connection, provided no assistance to get new flight

Smooth flight, especially take off and landing, and great crew on board. Really loved the stroopwaffles!

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

We boarded but then sat there waiting on some missed connection people to get on so we sat for about 15 minutes for that. Then we sat again because the passenger manifest was wrong and they had to figure it out before we could leave. That took about another 20 minutes or so. The crew was working hard to figure it out so it’s not their fault. It ended up being a system glitch where someone was upgraded to first class while another person was also in the same seat and it just created a mess that took a little while to figure out. They literally went to every person on the plane asking their names to see who was sitting in the wrong seat. I also hate the entertainment that must be watched on your phone or tablet. Just give us setback screens. It’s so much better. Almost every Delta flight has this now and it is so nice to have them. The crew did a great job. I have no complaints from them. They were very hard working, even with the mishap and a disgruntled passenger.

My priority checked bag was not loaded on the flight. I had to sit in baggage claim in Las Vegas for 2 1/2 hours waiting for the next flight. All baggage staff were very helpful, tracking showed it as scanned for loading. Nobody told me why it wasn't on my flight.

The tv monitor in front of my seat was not responding. The flight crew reset it and it still didn’t work.

Our seats were all the way in back of the plane,

Food choices were very limited. Taste of the dishes was average.

Maybe add a seat trade app for flyers that didn’t get seats together

At the beginning of the flight there was some turbulence and the announcement was made that there would be no beverage service. The turbulence only last about 5 minutes then it was smooth sailing. I noticed that first class got their service, but the rest of us did not.

Update departure times in a more timely manner. We are not boarding on time if the plane isn’t arriving until after our scheduled departure time.

Took off on time and successfully avoided weather that looked to be a problem along the way

I liked everything. Except that my neck was hurting on the seat. I couldn't sleep.

We were delayed Al ost / hours after boarding so that maintenance had to add oil to the engines. Then the oil they grabbed had been left out in the Dallas record cold and was frozen. They had to go back to the hanger and grab some that was not frozen.

Flight was empty so had a whole row to myself. Still had to wait to get the bag due to the negligence at Palm Springs departure.

Everything was on time, we arrived early, everything worked well.

Angela was the best fa ever. She made that 8 hour flight a breeze

This was a pleasant, short flight and the crew was friendly.

The service and food needs to improve to catch up with other international flights

Great! We boarded on time! Everything went so smoothly! The flight was so smooth

Seats uncomfortable, hard to check luggage, etc. It was like the last flight out of Hanoi

I will never fly with Spirit again. I was late getting through TSA after dealing with traffic and getting on the wrong shuttle. I got to the gate 2 minutes before the ticket said the gate closes and they agents were gone and doors were closed. They rescheduled my flight for 12 hours later and the agent had the nerve to tell me, “Be on time next time”. I was already upset from nothing going right for me that morning. I booked another flight through Alaska Airlines and they were very accommodating, nerer again Spirit Airlines!!!!

All was good expecting the seats need a bit of cushion. Besides that I can’t complain.

You get what you pay for, and the flights went smoothly. There’s no reclining chairs, no screens, And there isn’t always wifi, but the plane was clean and staff was friendly and the takeoff/landing were smooth.

It’s what we expected from Spirit..reasonable cost, good for a 2-3 hour flight. Disappointed that we had a 2 hour delay in departure from DFW for a maintenance issue, but the pilot handled it well once we were outbound on a different Airbus.

The flight was on time. The seats are very narrow.

Unclear pricing; ended up being charged an extra $52 just to get onboard

Flight crew was great. Spirit leaves a lot to be desired in terms of comfort.

would be great to get basic water, soda at least and stop charging for carry ons

Since you have to pay for overhead bags then they shouldn't be running out of space and asking individuals who paid to remove stuff from the overhead

Book with frontier airlines with the mentality that they'll cancel your flight, kick you off and lose your luggage. Anything besides that is a win. Compare prices with other airlines (to include luggage) and if frontier is still worth it, book it but know all of their policies.

You get what you pay for nothing essentially but a hard uncomfortable seat that doesn’t recline and kids screaming all around you and chaotic boarding and limited check bag weight allowance when compared to other airlines

Not very good. Paid in excess of $400 for assigned seating for my family and that was not provided. I want that money back.

I chose the seats when booked the flight and paid for them. However after checking in I found we were assigned different seats!

It was a no frills flight. Would have liked to be able to charge my device

Seats were extremely uncomfortable and it was very hot on the plane.

Would be great if Frontier can Assign Seats together under one PNR

Since they are a budget airline, I wasn’t expecting too much but they did some things well. They were on time, the plane was clean, boarding was fairly straightforward and the staff was cheerful and friendly. The only downside was comfort. The seats were fairly hard and after a 2 hour flight your rear end is not feeling so great. Maybe a little more cushion in the seats, Frontier!

Check in at Philadelphia international was absolutely terrible! I fly 2 to 3 times a month and avoid frontier at all cost and will never fly Frontier again! The night before travel, I tried checking in however, the app was giving me an error, so I went to the desktop, which instructed you that you need to use the app. The next day I presented at the check-in gate after trying at least a half dozen times prior to getting into the airport and continuing to getting the error in the app. I actually had rebooted my phone numerous times and reinstall the app just in case. My phone is only one generation older than the current model. It has no problems completing a frontier flight purchase or any other app issues. There was only three frontier employees working at check-in and a huge line while I was in line I continued to try and check in via the app. As I approach the desk, I was dreading dealing with the agent. He was extremely unprofessional, anti-semantic & very ignorant, and mean to the people in front of me, as well as the people who ended up being behind me. He literally told people “Man I don’t care bout y’all” in his native dialect! Maintaining my composure I approached and explained the situation. To which he replied, you’re gonna have to pay then! I don’t understand. It’s an issue with their app not allowing me to check in! Not my issue! He told me if I pay cash it would be $15, $25 if I pay credit card. I don’t understand a $10 difference for paying with a credit card? I am completely cashless so I continued to try using the app to avoid the $25 fee, Which I still don’t believe that I should be responsible for since it was Frontier’s technical issue!!! I continued to check in via the app a couple more times after he verified I was doing everything right he proceeded to continue to belittle the people behind me. Yelling at them saying I don’t care about you people! I cannot believe that this is the way that businesses would treat its customers! Unfortunately, the black mail with dreadlocks did not have a name tag all he had was a frontier sweater on! For the $25 fee that I ended up getting charged on my credit card. I should’ve just booked originally with Spirit or any other carrier! I have no problem paying fees that I should be responsible for, but when it’s due to a technical failure of a company, the customer should not be responsible for it! I cannot believe that it’s not frontier going out of business!
