Very crowded and very noisy . No way to really rest .

There wasn’t any entertainment nor food serve on our flight due to the short flight duration

This flight was on time, a bit of turbulence but manageable. Quick "tail wind" flight so no beverages or snacks. Getting baggage is quick

Extremely poor, 1st time this has happened though. Traveling during the holidays, didn’t receive an update that our flight was delayed 3hrs. Lost our place in Airport Spot Saver to go through crazy long line at TSA, gate change and then another hour delay (makes it 4hr delay for a 2 hr flight to Las Vegas), stayed on tarmac for almost 25mins after landing. So 6.5hrs from Seattle to LAs Vegas. Could have went to Cancun instead.

The plane was delayed for over an hour because of a family who didn't speak English, and didn't understand what was asked of them. While I understand the delay, I thought it was unfair to keep us all waiting for over an hour to get to our destination and a better approach should've been exercised.

Finally get a snack n drinks! Just like the good ole days!

The website said ear phones were provided in first class. They were not. But a lot of programs had captions

I didn’t make it because Alaska schedule my flight too tight, I had to run to the other side of the airport, and no one helped me get off the plane early or held the plane for me… so I missed it and it was Alaskas bad, not mine

The flight took off two hours late and involved a gate and plane change. It might have better if they had announced a problem from the beginning, not when we were boarding. Annoying, but better to be safe.

My experience was great! The crew is great always happy and friendly :) thank you Alaska!!

Other then mechanical/ computer problem and 3.5 hours flight delay the flight was great. I guess that what happened when you fly an old airplane now a day.

Coach seating is debilitating, neither my husband or I can walk the following day

Luggage delayed and 6 days later I still don't have it.

It was NOT pleasant. Started from checking our luggage to the last time getting off the plane. The crew was not friendly, the food was horrible and the seats were too close to each other that I got a bruise on my knee.

In thirty years of traveling, mostly with Delta, this was the worst day ever.

Late departure due to large number of wheel chair patrons. Used to having a box of snacks to select from in comfort plus. The flight attendant just rattled off what was available and asked us to pick. Felt rushed and uncomfortable. Seat was great. Prefer having the screen on the seat in front of me instead of having to pull it up from the seat side. Lots of room for my carryon under the seat in front of me.

The flight was canceled two hours before departure, it took over five hours to rebook us on another flight.

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

They were an hour late and they didn’t have my wheelchair for me

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

AA had a nationwide tech glitch today and after two connections snd hours of delay, I arrived 7 hours late to my destination

Was supposedly in main extra (row 10), but the seat spacing appeared to be regular economy (the head rest was blue, as well - same as economy, the seats in front of us had red head rests). Otherwise the flight was good and got in well ahead of schedule.

This was a horrible American Airlines experience, and it discourages me from flying with them again. It may have stemmed from a mechanical delay, but it appeared that the team was unprepared to respond to the delay. After boarding, we waited an hour before finally taking off. After landing at our destination, we waited an additional hour on the tarmac waiting for a gate (at 8:00pm) to be assigned and cleared. The flight crew did their best, but they were clearly tired and also ready to be done for the day. Because of the delay, I missed a connecting flight. It was a very poor experience.

When my flight was delayed due to weather, I was rebooked to another flight since it showed that I would miss my connection. It was a lot of work to get back onto my originally connecting flight which was also delayed. That part caused a lot of stress and frustration. The ticketing agent at the desk was not very helpful.

Flight areas delayed 3 hours , train in the airport didn’t work

The meals were mediocre and the alcohol selection was poor. I enjoyed the selection of movies and other entertainment.

Multiple maintenance delays and the missed and rebooked connection changed gates at least 6 times including one which had us walking 20 minutes to another terminal and then back again. Seated our family of three in different middle seats throughout the plane and then there was an empty seat next to me. Very long travel day which I would have never agreed to if I knew the itinerary would be changed at 5 am, 2 hours before takeoff.

We were offered Flight Change due to overbooking. We accepted and chose an earlier flight. We went to Rebooking center to make the change but agent told us no changes permitted on our Basic ticket. AA should not have made the offer to change our flight.

The flight was as good as it gets when flying. On time departure and arrival plus no lost luggage.

Flight was cancelled as I was in line for security. Next available flight got me to my destination 24 hrs later than the first. No refunds offered, just credit toward another flight. I booked with delta, got to my destination only 2 hrs behind my original flight schedule. Won’t be using American again.

Seats were surprisingly comfortable, and crew was polite. I did not like the baggage fee prices, the minimal amount of flight choices for my area and the difficulty of the self service bag drop.

I did not fly Spirit. Connie used my email while booking her flight. I do not know Connie. It's fraud!!!

Flight was ok with exception of the multiple delays. As with all Spirit flights, the sights are extremely uncomfortable and lack leg space. However, the price savings is the plus.

Okay for the most part but Good boarding and on time

Staying with Dallas 4 hour stay ...it's was torture sorry. .. about to say that

Quick flight. But crew was late so boarding was delayed. No food or entertainment as flight was an hour so no possible eating there…flight was also delayed but I think that was the fault of SAN airport not spirit…

Better overall experience from my first flight with Spirit several years ago. Efficient boarding (albeit I arrived after all rows were called) and flight actually left earlier than planned. I am still baffled by being charged for everything, even a non-alcoholic beverage. And there is definitely less seat room which makes a flight that’s more than 2 hours really uncomfortable.

The plane crew made the decision to leave a LARGE group of us passengers who were stuck literally at the gate next to the Las Vegas flight & trying to get off. We were lied to & told the Vegas to Dallas plane was going to wait for us. I’m having to fly the whole night to my destination now because of this

I liked the airfare price. Seats are not very comfortable. But I would fly again with Spirit for the price.

Nothing. Will never ever travel on Spirit or Frontier. Both of them Garbage Airlines.

Overall experience good. There was no food and seats were not terribly comfortable.

Boarding was organized and flight was on time. Overall very satisfied with my flight.

The takeoff was the smoothest I've ever experienced on any airline and this is the first time I've flown on frontier so this was an extremely pleasant surprise!

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.
