This was a code share Latam Airlines flight - everything very good except there was no seatback entertainment

Don't waste your money or points on first class. Delta first class is a joke. The seats were rickety, the food was awful, and nothing worked, wifi, my light, the power plug - and it was dirty - the fold out table was gross. For 2-3 hours, tough it out in Economy.

Loyal Delta traveler, but last nights flight was a train wreck. Seated in 1B after multiple delays. Then we couldn’t takeoff because of an issue with the passenger that was ‘not in compliance’ and had to deplane along with the threat if they did not deplane, all the passengers would be required to do so. Finally they were escorted off, but the experience threw off the crew. Disruptive for everyone. Service was a mess, televisions didn’t work, bathroom door kept swinging open during the entire flight whenever empty …

My flight was cancelled twice and the third time I tried to rebook it online I cancelled the flight because it looked like I would get a refund to my credit card. Instead I now have a credit. I was also on hold for three hours waiting for a representative and then disconnected. I will never fly delta again.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

5-hour delay due to storms in Tanoa and airspace restricted by Miami traffic controllers.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

Horrible. This was not first class. This was a connecting flight whi h was late. My original flight never came. I hated the fact that delta gave me a connecting flight from New York to Orlando Florida. No meals and the television screens were not working. There wasn't even any power to charge your phones. This is NOT FIRST CLASS DELTA!!! Do better next time!

Flight was delayed an no one make an announcement about it., they only have Coca Cola and nothing else., the food that was served was cold… very bad experience and service

They did a fine job. Can't wait to use Delta in the future.

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

There was no air on the plane and it was very hot.

Flight crew was amazing! I don't like that the Polaris seats are side-by-side.

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

Flight was 3 1/2 hour delayed with no credit or meal vouchers

Smoothly flight, pleasant flight attendants. I wish there were better food choices.

Everything was awful Flight attendant was condescending, rude and not helpful at all. Small outdated plane. No service, uncomfortable seats. Flight attendant was really the worst. He used hand gestures to communicate instead of words and whenever he used words he was condescending.

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.

This was a 5 hour flight with no entertainment and with a snack being provided (pretzels and fruit bar), which are both high in carbs and sugar. Nuts would have been a better choice.

I love to flight american however my carry on had to be sent with regular luggage and it was broken. Don't appreciate that. If when I buy a ticket says I can take a carry on and a hand item there should be space for mwsy stuff and not be basically forced to send the item even if it's at no charge. A.A. needs to work on that. Everything else excellent.

One of the reasons I fly American is because the seating is more comfortable than most airlines. Even in the back of the plane.

The flight was delayed which was disappointing. There was no pre takeoff refreshment in first, as we had to wait around an hour in our seats before take off that was disappointing too. The inflight entertainment/wifi did not work, and the crew were slow to offer drinks in flight

On time, smooth, luggage was out fast at the end of the flight. About perfect.

Pilots showed up late because they decided to stop and get something to eat instead of going straight to our gate, Forcing an 1 1/2 hour delay, and missed flight. Shame on the pilots.

There was a serious delay of almost 2 hrs to departure.. it would have been to be told what caused the delay. Apart from the delay, boarding and the flight itself went smoothly.

Flight departed on time and arrived a bit early. Can’t go wrong with that! And makes a travel experience go so well

WiFi wasn’t working on the flight, several delays and gate changes, ended up taking off 3 hrs later

The flight was quick which gave me more time to get to my other flight.

Terrible. We had about a 3 hours delay which led to us missing our connecting.

Everything was excellent and as expected. The boarding process was great but deboarding was a bit slow. No fault of the crew; it just seemed like the passengers didn’t want to leave! 😂

The flight was delayed and the announcements were hard to hear, but the crew was great

I liked the low price. I did not like the cramped passenger seats. As a below average size person I was cramped in the seat; I can only imagine how uncomfortable an average or large size person would be. I guess that is part of the deal with low cost airlines.

It just baffled me that spirit boarding process that I was charged 2 check in fees for a person bag and carry on. I ended up lugging 3 kids under 10 with 2 bags and to find out at the boarding area that I could not get on the plane due to my lack of reading the baggage policy. I understand if that was the case but the agent also failed to understand one item was in fact a personal item such as laptop bag and charge me as if it was a carry on not personal item. And knowing it’s a horrible storm and last flight in the destination of travel. I could have very easily handed the items to my relative to keep but I didn’t learned about this enforced policy until I was about to board.

I’m not a fan of Spirit Airlines from a not-so-good experience the last time & I swore I would not fly this airline again- bc they charge for EVERYTHING. I only flew Spirit this time bc it wasn’t my choice. I decided to use a “Mystery Ticket” bc of the great price, not knowing it would choose this airline! I found out on this trip how they pick a random seat with a “sticker” for a prize-are we in first grade? just doesn’t seem right & now the first 3 or 4 rows get special treatment-we all paid for our tickets, not just them.

This was the best spirit airlines fight I have ever had. I take spirit up to 3 or more times a year and I am ready to be the Jared of spirit. 🤪 Best flight ever. Everyone was great. I hope my return flight is the same. When you're traveling with a 9 month old you need a different type of care and accommodation. I didn't ask the staff for anything but I didn't have any added stress.

Everyone on the plane was wonderful. I can't say that the trip of flying was wonderful because I hadn't done that since I was 13 years old. Honestly I was terrified. What would make it better is if they didn't drive so fast but I know they have to. And if they could go up slowly and land slowly. But none of that they can control.

Horrible airline with terrible customer service! I was at the Atlanta airport going to Ft Lauderdale. They delayed the takeoff time several times. We finally boarded & taxied away from the gate where they had us sit in a hot airplane for an hour & a half before cancelling the flight due to weather. They did not even offer us water. They took us back to a totally different gate where they said agents would be available to help. Instead, they dumped us out & left us to fend for ourselves. We had to go out of security to go pick up our checked luggage & wait in a long line at the ticket desk where only one agent was working & by the time we got to the front of the line over an hour later, all the flights were full for the rest of the day & only limited seat availability for the next day. If you were one of the lucky few that was able to reschedule the same day flying to the same or a different airport, you had to go back through security & ride the train to get back to the correct date which took over an hour more. A total waste of time. I will never fly Spirit Airlines again!!

Very bad flight was delayed. After they boarded us kept us in plane four 4 hours because they didn’t have fuel. Very unprofessional. Plane and bathrooms were very dirty. AC was blowing very cold. After everything went very bad because od them they rebooked connection flight next day more than 12 hours. Didn’t provide hotel voucher. Never going to fly this airline

Spirit cancel my flight. Many times happen in my travels.

Airline changed the gate from Terminal A to Terminal D which is quite far and only sent a text message few minutes before boarding. Around 50 people missed their flight and as plane didn’t wait for them.

The personal at boarding are rude and try to steel people with their rule of personal item , really bad experience for us

I did not like that people are purposely split ip who book at the same time because we didn’t buy seats. No other airline does that.

Horrible my trip was delayed 3 hours, we already have set in the plane and they delayed the flight.

Checking in was easy and simple, crew was nice and efficient, but I would improve seat assignment randomness to make it easier to sit together based on when you check in. Overall would fly with them again.

It was delayed 9 hours for operational reasons, despite the plane arriving to the airport on time.

I am very disappointed with Frontier Airlines. They cancelled our flight because they couldn't find a crew member, and then didn't get us to our connecting flight. We had to cancel our whole vacation. We were promised flight and hotel vouchers, but they never sent them.

I fly Frontier because it’s affordable. I understand that the seats are tight and not the most comfortable…but that’s part of it. The problem with this flight was that there was a group of travelers directly behind me at the back of the plane who were ridiculously loud and obnoxious the entire flight. I’m pretty sure they were drunk and I could periodically smell an odd odor that I believe was one of them using a smokeless vape pen. The stewards had to remind them to keep quiet during the pre-flight instruction, but that was it. They never said another thing to them for the rest of the flight. It was a miserable.

Six hour delay. Poor customer service. No voucher. Bad communication. Missed important appointments.

I purchased a carry on bag online…was supposed to cost $72 but after a whole slew of bs charges, the total was over $175.00. Because of these hidden charges, I will not even consider flying Frontier ever again. It’s just not worth the hassle. I’m scratching this company off my list forever.
