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

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!!

We were delayed over an hour because of fog at the destination--not Alaska's fault, but it still made the experience a little frustrating on the day before Thanksgiving.

We were amazed by the amazing food, comfort and service received in our coach seats. Pleasantly surprised we received breakfast and great beverages for no charge. Bag check fee was on $35. The crew was so kind and helpful. Highly recommend!

SeaTac was a mess first class check-in not clearly identified Temporary signage needed since only one door into Alaska check-in area directed you to coach baggage check.

We could not find a parking spot in the garage so we left airport to find a parking lot. We were late and afraid we would miss our flight. We were greeted at the new Alaska check in and I was really upset. She got two people to put us in wheelchairs and we flew through the airport and security. Then all the way to the N gate and on to the plane. Somehow they hadn’t taken off. These two individuals deserve a medal for getting us to our flight and onto the plane. It all started with the wonderful greeter at check in. I wish we’d gotten her name and the two who got us there.

When I made my transfer from my flight from Missoula to Seattle to Seattle to San Jose, the gate was at the opposite end of the airport, which I thought was inconvenient since there were so many gates for Alaska right where I landed that everything was good

Cabin was a bit cold. Didn’t seem like they turned up the heat until we were half way. All personnel were wonderful.

Really appreciate the water offered in addition to the beverage service.

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!

Our flight was delayed in Atlanta. The staff could have gave us an explanation for the delay and how long it would be.

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.

Checked in the minute I was allowed and still wound up in group 8 for boarding.

great experience. minimal lines at BWI. at DFW they got a long haul 787 boarded in 30 minutes

These are the things that AA did right on this flight:1 Smooth Boarding Process, 2 Departed on time, 3 Arrived early at destination 4, Friendly and courteous staff. Great job AA!

More room. International flight - by the time you put your purse and shoes under the seat in front of you, add in the pillow and blanket they give you- makes for tight fit.

Overall good. Tight connection in DFW because of gate unavailability upon landing.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

Excellent customer service at check in at Austin flight to DFW and excellent customer service from Karren in terminal B at DFW.

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.

For the price we paid, the service was outstanding, we took off on time, everything went very smoothly, we landed on time, and we didn't need anything extra.

spirt air lines took advantage of two eighty year olds. we paid extra for cancelation due to health reasons they did not honer they have no spirit. I hope they treat there grand parents beter.

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

While booking it was not obvious that I had to pay for carryon. Realized it only during check-in. Overall, meh!

The boarding gate was in Terminal D, but the Frontier counter was in Terminal E. So I had to move back and forth between terminals to check in my luggage. This was the worst experience that I had in terms of flights.

My first flight was moved 6 hours causing me to miss my meeting. The second was delayed about an hour and a half. Most of the crews apparently dont like their jobs or just working for Frontier. Only one flight attendant wasn"t snappy or rude.
