I elected to pay for the upgrades and found very little difference

The new seating arrangement is so over priced for what you get.

No food or entertainment, just a quick 40 minute flight. A little bumpy due to Santa Ana winds but pilot has no control over that. Good flight and landing!

Snacks are always pretzels. Why can't you also offer peanuts ?

Flight was hours late, unable to sit next to spouse, I have had so much better experiences. Substantially better, only saving grace was that it was a short flight.

An entire day of delays. Cost lots of money. Meals and a hotel.

WiFi did not work. Boarding with the new seating assignments took too long. The temperature in the terminal was obnoxious. +/- 80°

Only downside was the legroom and seat width, which is always a problem unless I spend more for a premium seat.

Paid for premium extra leg room but the bin space for rows 1-3 had to go in rows 4-6 and 4-6 had to go to 7-9 because flight attendants have snacks and their luggage upfront. So we pay extra to have to fight thru traffic to get our bags. Only 2nd day of new seating so hope they fix this.

Great flight but super high price. Glad it was a business trip and not personal

Delay after delay with little communication then AA lost my luggage and at airport would not assist just said scan this QR code to track your luggage and submit a claim. However QR code provided did not work so have to go back to airport

Where do I start!! I was delayed with my flight from Dallas to Tampa. On the way back from Tampa to Dallas the flight was delayed over 4 hours+. I was put on another flight that was also delayed but not as long. Traveling on American Airlines is becoming exhausing.

Dloght delayed by 2.5 hrs . Common theme in my last four american floghts

The flight attendants and the service is getting worse by the day.

They are rarely on time! Very hard to plan your travels when flights or connections keep getting delayed.

Forced to check bags. Crew uninterested in collecting trash. Unclean seats.

Mediocre would be best description. Food bland. Seat biz class uncomfortable to sleep. Crew never dimmed lights completely in an overnight flight to Europe. Would avoid AA if possible.

It's very confusing because Kayak has it as American Airlines, but it was Hawaiian Airlines, but operated by Alaska Airlines. I had to go to the airport for my boarding pass because American said I didn't have any trips.

Massimo, flight attendant was very authentic, attentive - wonderful. Food/wrap was just okay.

I am an AA flyer for a very long time... AA has yet to disappoint.

The entire experience was so surprisingly pleasant. And the blocked extra seat between us was such an amazing and nice bonus. Great experience all around and I can’t wait to fly with spirit again!

For the cost you can't e too critical, but the inablitiy to recline the seat and minimal cushioning in the seats made for a less than comfortable flight. Other than that we had an ealry departure and arrival, boarding was smooth.

Horribly late because they had no crew!!! And then jet bridge didn’t work!! Then we arrived at a gate at lax miles away that we had to take a shuttle to a terminal!! I was over 3 hours late to getting the LA! Should have been here at 8:30 and at an appointment at 10:30 and arrived and left lax at 11 am!! Horrible experience!!!

Liked early boarding for disabled customers. Seat comfort could have been better, would have appreciated an empty seat between my wife and I since I suffer from arthritis, neuropathy, and spinal stenosis. Also aisle seat armrest was immobile and this made it difficult to get into and out of my seat during the flight

Horrible experience. First and last time using this airline. Made an announcement that boarding will start in 15 minutes, canceled the flight 5 minutes later due to no airline staff. Had to book another flight on Delta since Spirit had no other flights arriving to my original destination the same day. I wouldn't recommend anyone to fly with Spirit. No wonder why it consistently ranks high among worst airlines.

The airplane had a strange noise that was constant throughout the flight. Thankfully I had noise-cancelling over-ear headphones that muted much of it.

The plane was supposed to leave at 12:59 Amma and another plane took us around 9:30 am. There were 7 delay announcements. We were to receive a voucher of $12 back to pay for food at any place in the airport. One passenger tried to use the voucher was denied. I did not receive the voucher for me, my son, and grandson. I went to the desk and informed them and they took my phone # and email and they told me to wait. I did and was never sent. The plane was uncomfortable, the crew was dismissive of anyone beyond the last two seats. I will NEVER fly or recommend Spirit Airlines again.

I liked that the crew looked well put together. I also liked that there were little turbulences.

Absolutely horrible. Usually pay $40-$50 to check luggage in. I tried to check my suitcase in and the price is raised to $70. That's ridiculously greedy c'mon. I had to leave my suitcase with all my clothes and hygiene products and repurchase once i landed in Atlanta. You guys make it really stressful to travel. Don't even want to travel anymore.

I was never aware that I had to pay $100 per luggage to them on the plane that are simply carry-ons. This is discriminatory and I’m going to be alerting my entire family and friends and my Instagram following up over 75,000 of this issue and misunderstanding, including mismanaging.

More inflight connection. And leg space is horrible. And the paying for baggage I'd ridiculous!!!

My flight was originally from SAT to MCO connecting from MCO to ORD. We got diverted to ATL and than Frontier staff there was sooo un helpful first they said they couldn’t give us any accommodation since our flight first got delayed that cancelled and now it’s 221am and I am still in ATL since they said they need to create a new flight my final destination is ORD and I have been delayed twice and cancelled. With no real help the frontier app didn’t work no email updates over all such a horrible experience

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!!

Remind customers of the need to have passport or new ID for boarding.

Flight was canceled. Most upsetting was message from Kayak, stating that the flight was canceled and click with Kayak for details regarding rebook, refund details. THERE'S NO INFORMATION PROVIDED BY KAYAK EXCEPT THAT FLIGHT IS CANCELED. AND NOW THIS SURVEY TO FIND OUT HOW WAS THE FLIGHT !!!!!!!

The flight never took off and we spent 7 hours at the airport

Frontier.. nickel and dime add-ons. Flight late, on time, late again, last minute gate change, arrival gate required a shuttle to the terminal. They sure keep you guessing.. if you like a little chaos and airport anxiety, this is the airline for you!

When I wanted to check in 3 hours prior to boarding time, the employees mentioned “a little over an hour delay” so I waited for an hour then I went to go look for food in the terminal and most people from that flight were in the same area looking for food. Finally I decided after food to check to see if it’s anytime closer and now it’s 2 mins until boarding closes?! What are you kidding me? I didn’t receive anything via sms about boarding now nor via email or on the intercom. I luckily made it through, barely, and then there’s no room for my carry on mind you I’m in the very first row so I had to place my purse in one further row back and my carry on sections down. Not sure who pays for better seats to get your stuff placed all over the plane but that was the worst experience I’ve ever had flying with anyone.

baggage clamed had to wait over a hour and half for all people on my flight it was terrible

My flight was canceled I was promised a reginf still not received.
